How to Create Your Own Payment Gateway: Step-by-Step Guide

Creating a payment gateway means building and certifying the software that authorizes, routes, and supports the settlement of card payments. Once integrations, compliance, infrastructure, and operations are included, it can become a multi-month, high-six-figure infrastructure project.

The payment environment continues to expand in both volume and complexity. According to Federal Reserve research, general-purpose card payments in the United States grew by 6.0% in number and 10.5% in value between 2021 and 2022, while mobile wallet payments reached 14.4 billion in 2022, up from 2.9 billion in 2018. This growth increases the pressure on payment businesses to support higher transaction volumes, additional payment methods, and reliable processing infrastructure.

For payment service providers, fintech companies, SaaS platforms, and ISOs, understanding how to create a payment gateway starts with recognizing the scale of the responsibility. Owning gateway technology can provide greater control over payment flows, merchant services, data, pricing, and product development. However, it also creates permanent engineering, compliance, security, and operational obligations.

This guide explains how to create your own payment gateway through 12 practical steps. It also covers the real costs, essential architecture components, security controls, and the questions companies should answer before committing to an in-house build.

For companies that want to operate payment infrastructure under their own brand without creating every layer internally, a white-label platform such as Akurateco can provide a more practical route.

What Is a Payment Gateway, and How Does It Work?

A payment gateway is the backbone of online payments. This technology allows businesses to accept transactions securely. It connects a customer’s payment method, such as a card or a digital wallet, to the merchant’s acquiring bank or processor. Its primary mission is to verify, encrypt, and transmit sensitive payment data to ensure every transaction is completed safely.

In the world of online transactions, it is easy to confuse terms such as payment gateway, payment processor, payment service provider, and merchant account. Although they are all essential parts of the payment infrastructure, each performs a distinct function.

A standard payment transaction follows five basic steps:

1. The customer initiates payment on the merchant’s website.
2. The payment gateway captures and encrypts the payment information.
3. The payment processor connects to the card network for authorization.
4. The issuer bank, which is the customer’s bank, approves or declines the transaction.
5. The gateway returns the issuer’s response to the merchant and, in real time, confirms the result to the customer.

In simple terms, a payment gateway acts as a secure communication layer between the customer, merchant, processor, acquirer, and issuer. It ensures that sensitive payment data reaches the correct parties and that the merchant receives a reliable transaction result.

Why Build Your Own Payment Gateway? Pros and Cons

Companies usually decide to build their own payment gateway when payments become a central part of their product or revenue model. Instead of adapting their operations to a third-party gateway, they want to control how transactions are accepted, routed, monitored, and reported.

The potential benefits are significant, but building a payment gateway also means taking permanent responsibility for critical financial infrastructure.

Fee control

A custom gateway lets a payment business choose processors and acquirers, negotiate commercial terms, set merchant pricing, and control margins. At scale, lower external gateway fees may create savings, although interchange, network fees, acquiring costs, fraud losses, hosting, and staffing still remain.

Customization

An in-house platform can be tailored to a specific business model, region, merchant segment, or transaction flow, including custom routing, checkout, integrations, billing, reporting, and merchant-management tools. However, every feature must be built, tested, secured, and maintained internally.

Data ownership

Operating a proprietary gateway provides direct access to transaction data, merchant activity, provider responses, declines, refunds, chargebacks, settlements, and performance indicators. This can improve routing, reporting, pricing, fraud analysis, and product development, while also increasing responsibility for data security and access control.

Market differentiation

A custom gateway can support specialized payment methods, risk controls, reporting, routing, and merchant experiences that differentiate a PSP or fintech. This advantage depends on continuous investment in provider integrations, security, payment methods, and product development.

Costs and operational responsibilities

Building and operating a gateway requires engineering, DevOps, QA, security, compliance, product, and payment operations resources, alongside infrastructure, certifications, fraud management, reconciliation, merchant support, and ongoing releases. When estimating the expenses of internally developed software, maintenance must also be included and can amount to approximately 20 percent of the initial development cost annually.

Building is most likely to make sense when payment technology is a strategic business asset, and the organization is prepared to maintain it as permanent financial infrastructure.

Build or Buy? A 5-Question Decision Check

The choice between licensing a white-label payment gateway software and building in-house depends on the strategic value of owning the technology, the available budget, and the required launch timeline.

Before making a build vs buy decision, answer these five questions.

1. Is payments your core product?

Building is easier to justify when payment technology is central to the company’s revenue and competitive positioning rather than a supporting function.

2. Can you fund a permanent payments and compliance team?

The work continues after launch through annual audits, software updates, integrations, infrastructure monitoring, fraud operations, support, and regulatory changes.

3. Do you need to generate revenue from processing itself?

Owning infrastructure may make sense when transaction fees, merchant services, and payment technology represent major revenue streams.

4. Is launching within six months critical?

An in-house build is unlikely to be the right option when the company needs predictable near-term market entry.

5. Do you already have PCI DSS and payment-security expertise?

Without internal expertise, the company must hire specialists, work with external consultants, and allocate additional time for remediation and certification.

Several “no” answers usually indicate that purchasing or licensing infrastructure is more practical. For a complete analysis, read our build-vs-buy guide for PSPs.

How to Build a Payment Gateway from Scratch: Step-by-Step

Learning how to build a payment gateway from scratch starts with understanding that the product is more than a checkout page or transaction API. It must connect merchants, processors, acquirers, payment methods, security systems, reporting tools, and operational teams.

The following steps to create a payment gateway cover the process from defining the business model to operating the platform in production.

1. Understand the business model of a payment gateway

Before starting the build, determine how the gateway will generate revenue and what role it will perform within the payment ecosystem.

Revenue may come from transaction markups, setup charges, recurring platform fees, gateway access, fraud-management tools, reporting, currency conversion, or other value-added services.

Define the merchants, industries, regions, payment methods, and transaction flows the gateway will support. Akurateco’s guide to how payment gateways generate revenue explains the most common pricing structures in greater detail.

2. Establish objectives and requirements

Document the gateway’s functional, technical, operational, and regulatory requirements.

Define expected transaction volumes, currencies, merchant types, settlement models, provider connections, payment methods, user roles, reporting needs, and deployment regions.

The requirements should also specify availability targets, response times, data-retention rules, security controls, disaster-recovery objectives, and the responsibilities of each internal team.

3. Recruit a skilled development team

Assemble a team with experience in software engineering, payment processing, infrastructure, cybersecurity, and compliance.

A typical project may require a product manager, business analyst, solution architect, backend and frontend developers, DevOps engineers, QA engineers, security specialists, and compliance professionals.

Payment-domain knowledge is essential. Transaction states, retries, captures, refunds, chargebacks, settlements, and provider responses cannot be managed like ordinary e-commerce records.

4. Choose technology stack

Select programming languages, frameworks, databases, infrastructure, observability tools, message queues, and deployment technologies that match the gateway’s performance and security requirements.

The technology stack should support horizontal scaling, service isolation, automated deployment, disaster recovery, secure secrets management, and reliable processing during traffic spikes or provider outages.

5. Design architecture

Create a scalable architecture based on expected transaction loads, merchant configuration, provider connectivity, and operational requirements.

Define how the payment API, token vault, routing engine, provider connectors, reporting services, ledger, merchant-management system, and administrative interface will communicate.

The architecture must also define the cardholder-data environment so that systems outside this boundary do not unnecessarily enter PCI DSS scope.

6. Implement core features

Create the central gateway capabilities, including payment creation, authorization, capture, voids, refunds, transaction-status retrieval, error handling, recurring payments, and tokenization.

For a commercial PSP platform, the core functionality should also include merchant onboarding, user roles, fees, limits, routing configurations, transaction monitoring, reporting, and operational tools.

7. Ensure system security

Implement layered controls to protect payment information and gateway operations.

These controls should include encryption, tokenization, hosted payment fields, access management, network segmentation, fraud prevention, audit logging, rate limiting, and protected key storage.

Payment routing should remain separate from the fraud and security controls that determine whether a transaction is safe to process.

8. Integrate with payment processors

Connect the gateway to the APIs of processors, acquirers, banks, payment methods, fraud providers, and other required services.

Each connector needs request mapping, response normalization, authentication, timeout handling, retry logic, status synchronization, reconciliation support, and continuous maintenance when the external provider changes its API.

9. Perform a system test

Run unit, integration, contract, performance, resilience, security, and end-to-end tests.

Test both successful transactions and edge cases such as duplicate requests, timeouts, partial captures, delayed webhooks, processor outages, authentication failures, and inconsistent statuses.

Load and failover testing should confirm that the gateway can continue processing or fail safely when individual components become unavailable.

10. Obtain the necessary certifications and licenses

Complete the certifications, registrations, contractual approvals, and audits required for the gateway’s business model and target jurisdictions.

These may include PCI DSS validation, penetration testing, processor or acquirer certification, card-scheme requirements, data-protection controls, and authorization as a regulated payment provider.

Technology certification and regulatory licensing are separate workstreams. The exact obligations depend on whether the company supplies gateway software or also performs acquiring, money movement, merchant settlement, or other regulated services.

11. Go into the live mode

Deploy the gateway through a controlled production launch.

Start with selected merchants, providers, transaction types, or regions before increasing volume. Use monitoring, dashboards, logs, and alerts to track latency, errors, approval rates, processor availability, queue delays, reconciliation differences, and suspicious activity.

12. Conduct ongoing maintenance

Establish permanent processes for software updates, provider changes, vulnerability management, infrastructure scaling, support, certification renewals, and incident response.

The team must continuously maintain integrations, improve routing, update fraud rules, add payment methods, renew certificates, and adapt to regulatory and card-scheme changes.

Architecture Blueprint: What You Are Actually Building

Payment gateway architecture design begins with defining the card-data environment boundary. Card numbers, card verification codes, encryption keys, and detokenization services must remain within a tightly controlled environment.

Merchant dashboards, analytics systems, support tools, and most business applications should receive tokens or masked data instead of raw card details.

A secure token vault receives sensitive payment data and replaces it with a non-sensitive token. Other gateway services use the token to process recurring or subsequent transactions without storing the original card number.

The gateway also needs a transaction state machine. A transaction may move from created to authorized, captured, and settled, but the model must also support failed authorizations, partial captures, voids, refunds, reversals, chargebacks, and expired transactions.

State transitions should follow explicit rules rather than allowing individual services to overwrite transaction statuses freely.

Idempotency keys protect customers and merchants from duplicate charges. When a merchant retries a timed-out request with the same key, the gateway should return the original result instead of creating a second transaction.

Message queues help isolate services and handle tasks that do not need to block the initial payment request. Webhooks, reporting, reconciliation, notifications, and provider-status checks can be processed asynchronously.

Merchants should receive signed webhooks for events such as authorization, capture, refund, chargeback, and settlement-status changes. The contract must define signature verification, duplicate-event handling, retry intervals, and event identifiers.

Finally, the gateway needs an internal ledger and daily reconciliation process. The ledger records the financial effect of transactions, fees, refunds, chargebacks, and settlements. Reconciliation compares these records with processor or acquirer reports and sends discrepancies for investigation.

Read Akurateco’s guide to payment gateway architecture for a deeper technical explanation of gateway components and data flows.

The Core API Surface

To create a payment gateway API, begin with a small and stable contract covering the complete payment lifecycle.

The purpose is not to expose every internal service. Merchants need predictable operations, clear error responses, and consistent transaction states across different processors.

Each request should include a unique merchant reference, an idempotency key where appropriate, amount and currency validation, structured error codes, and a consistent response model.

The webhook contract should document event types, payload versions, signature generation, verification instructions, retry behavior, and the conditions under which merchants should retrieve the latest transaction status.

This article describes the minimum API surface at the contract level. It does not provide production code or a working processor integration.

Security Implementation Checklist

Understanding how to create a secure payment gateway requires translating PCI DSS and security principles into concrete technical controls:

• Hosted payment fields isolate card-data collection from the merchant’s general application.
• Tokenization replaces card numbers before other gateway services store or process transactions.
• Encryption in transit protects merchant, processor, administrative, and internal-service connections.
• Encryption at rest protects databases, backups, logs, and files containing sensitive information.
• HSM or KMS infrastructure protects cryptographic keys and supports controlled rotation and revocation.
• Network segmentation isolates the cardholder-data environment from analytics and corporate systems.
• 3-D Secure 2 supports issuer authentication and challenge flows.
• Fraud scoring evaluates transaction, device, merchant, payer, velocity, and behavioral signals.
• Audit logging records administrative actions, configuration changes, and access to sensitive systems.
• Rate limiting protects payment APIs against abuse, credential attacks, and accidental retry loops.
• An incident response plan defines detection, escalation, containment, communication, and recovery.

After the technical foundation is ready, setting up a payment gateway moves into the practical launch sequence: completing integrations, testing the full transaction lifecycle, obtaining approvals, deploying gradually, and establishing permanent support. That sequence takes the platform from initial testing to a fully operational live environment.

Key Factors to Consider When Building a Payment Gateway

The transaction API is only one part of what is required to make the platform commercially viable. A platform operator must consider how the system will perform across multiple merchants, payment methods, processors, markets, and operational teams.

Organizations that intend to build a payment system must account for scalability, fraud operations, merchant conversion, regional payment preferences, and long-term product expansion.

Scalability and uptime

The gateway must handle growing merchant numbers, transaction volume, traffic spikes, and provider integrations without creating a single point of failure.

Capacity planning should cover application services, databases, queues, tokenization systems, dashboards, reports, and connector traffic.

High availability also requires redundancy, automated failover, backups, disaster-recovery testing, and clearly defined recovery objectives.

Fraud and chargeback management

Fraud controls should combine transaction rules, velocity checks, payer and device signals, merchant-level configurations, blocklists, allowlists, and third-party scoring.

Chargeback functionality should allow operational teams to receive dispute notifications, connect them with the correct transaction, collect evidence, monitor deadlines, and report trends to merchants.

Checkout experience

A platform operator must optimize checkout across the different merchants it serves.

Hosted pages, payment fields, redirects, authentication steps, mobile behavior, local languages, and payment-method presentation can all affect your merchants’ conversion rates.

The gateway should support merchant-level configuration without requiring custom engineering for every checkout variation.

Multi-currency and local payment methods

International payment acceptance requires more than displaying prices in different currencies.

The gateway must manage currency validation, provider availability, settlement currencies, regional restrictions, payment-method-specific fields, refunds, and reporting.

Supporting cards, bank transfers, wallets, and local payment methods helps merchants offer customers the payment options they already trust.

Value-added services

Recurring billing, digital wallets, Buy Now, Pay Later, invoicing, payment links, network tokenization, account updater services, payment analytics tools, and automated onboarding can expand the platform beyond basic payment acceptance.

These services may improve merchant retention and create additional revenue streams.

Microservices approach

A microservices approach can isolate payment processing, merchant management, provider connectors, reporting, reconciliation, billing, fraud management, and notifications.

Teams can deploy and scale these services independently when their boundaries are designed carefully.

However, microservices introduce distributed-system complexity. The architecture must account for duplicated events, eventual consistency, service communication, monitoring, deployment coordination, and recovery.

How Much Does It Cost to Build a Payment Gateway?

A realistic cost estimate must cover more than just the first software release.

The total investment combines product engineering, certification, infrastructure, provider integrations, security tooling, permanent operations, and long-term maintenance.

ScienceSoft’s estimates that a custom gateway costs $100,000–$300,000+ and takes approximately 6–11 months to build. Stripe states that creating the necessary gateway software may take between six months and one year, depending on complexity.

These figures are initial benchmarks rather than complete three-year cost-of-ownership estimates.

The final figure depends on the number of integrations, payment methods, merchant tools, supported markets, availability requirements, deployment model, and level of customization.

A basic transaction API connected to one processor is not comparable to a commercial PSP platform with merchant onboarding, routing, cascading, billing, reconciliation, reporting, fraud management, and 24/7 support.

Companies evaluating internal resources can also explore payment gateway development services to better understand the expertise and implementation work involved in building production-ready payment infrastructure.

The Break-Even Question

Owning a gateway becomes cheaper than paying an external technology fee only when annual savings exceed the gateway’s amortized build cost and fixed operating expenses.

The break-even calculation requires three main variables: annual fixed cost, savings per transaction, and annual transaction volume. Processing a high monetary value does not automatically create a break-even point because the relevant metric is the avoidable fee per transaction.

A simplified formula is:

Break-even annual transactions = annual operating cost plus annualized build cost, divided by savings per transaction.

For example, assume a company spends $300,000 on the initial build and amortizes it over three years. If annual operations cost $250,000, the annual cost base is $350,000.

If owning the gateway saves $0.05 per transaction, the break-even point is:

$350,000 ÷ $0.05 = 7,000,000 transactions per year.

This example does not include financing costs, fraud losses, downtime, unplanned integrations, or the opportunity cost of delaying market entry. Companies should calculate conservative, expected, and high-volume scenarios before approving the project.

Can You Create a Payment Gateway for Free?

No. You may create your own payment gateway without paying software license fees by using open-source components, but operating it in production still involves high costs. Even if the software license is free, operating the gateway still involves ongoing costs for infrastructure, security, processor relationships, certifications, and staffing.

The unavoidable expenses include:

• Hosting, databases, backups, monitoring, and network infrastructure
• PCI DSS assessments and penetration testing
• Processor, acquirer, and payment-method fees
• Engineering, DevOps, security, and QA personnel
• Continuous monitoring and incident response
• Provider integrations and certification
• Fraud prevention and chargeback operations
• Compliance and legal work
• Maintenance and vulnerability remediation

Open-source software changes how certain engineering costs are allocated. It does not eliminate the responsibility for operating secure and compliant payment infrastructure.

What About Open-Source Payment Gateways?

An open source payment gateway can provide useful building blocks rather than a complete operating business.

Projects such as Hyperswitch offer open-source payment orchestration and modular payment functionality. Kill Bill provides open-source billing and payment infrastructure with APIs and gateway plugins.

These projects may provide a transaction model, connector framework, routing functionality, billing engine, APIs, or administrative components. They can reduce the amount of software that must be created from zero.

However, a self-hosted payment gateway still requires deployment, security hardening, provider integrations, PCI DSS preparation, monitoring, certification, reconciliation, operational support, and continuous upgrades.

The software license may be free. Running the platform is not.

Custom vs. White-Label Payment Gateway: Which Option Is Better?

The right decision between a custom build and a white-label platform depends on product strategy, engineering capacity, available capital, and launch expectations.

An in-house payment gateway gives you full control over the entire infrastructure, but it also comes at an equal cost.

A custom payment gateway provides control over the codebase, architecture, integrations, product roadmap, and operating model. However, the company remains responsible for engineering, testing, security, certifications, provider maintenance, monitoring, documentation, and support.

Adding a single connector, for example, can take two months. Multiply that by dozens of connectors, and the timeline and costs rise exponentially.

A white-label platform provides a ready technical foundation that can be branded and configured for the payment business. The company retains control over merchants, pricing, commercial terms, provider relationships, and market strategy, while the vendor maintains the core software.

A custom platform is most suitable for organizations with mature payment-engineering teams and a strategic reason to own every technical layer.

White-label infrastructure is usually more practical when speed, operational readiness, and predictable costs matter more than complete source-code ownership. For a more detailed look at this model, see the complete guide to white-label gateways.

How Akurateco Helps You Launch Your Own Payment Gateway Faster

Many PSPs, fintech companies, and payment businesses use white-label technology because they need control over a branded payment offering without creating the complete infrastructure internally.

Akurateco’s white-label payment gateway provides a ready foundation for launching and operating a payment platform under the client’s brand.

Instead of creating merchant management, provider connectivity, reporting, billing, reconciliation, security tools, and back-office functionality as separate projects, companies can configure them within one ecosystem.

Businesses retain control over branding, merchants, pricing, commercial terms, target markets, and provider strategy. Akurateco maintains and updates the core software, supports integrations, and offers different deployment models.

The ecosystem includes:

• Smart routing
• Cascading
• Recurring billing
• Automated merchant onboarding
• Payment analytics and reporting
• Fraud-prevention tools
• PCI DSS Level 1–certified infrastructure
• Chargeback-management functionality
• Merchant, fee, and limit configuration
• Provider-agnostic payment connectivity

A white-label gateway does not replace the legal, licensing, acquiring, risk, and commercial responsibilities of operating a payment business. It provides the technical foundation needed to manage those responsibilities without independently creating every software component.

Real Results: How Businesses Succeed With Akurateco

A white-label platform is most valuable when it helps a payment business solve a specific regulatory, integration, localization, or scaling challenge.

Dinero Pay and TESS demonstrate how Akurateco’s infrastructure supports different market and operational requirements in the MENA region.

Dinero Pay — Saudi Arabia

Dinero Pay needed to launch a mobile-focused payment platform in Saudi Arabia while meeting local hosting, data-protection, and financial-sector requirements.

Creating the complete gateway infrastructure and wallet integrations internally would have increased the cost and delayed market entry.

Akurateco configured its white-label platform for deployment on Oracle Cloud Infrastructure and supported integrations with Apple Pay, Google Pay, Tabby, and Tamara.

The project also included local infrastructure configuration, merchant onboarding, routing, retries, analytics, training, and fraud-prevention tools.

Outcome: Dinero Pay achieved SAMA certification, reduced engineering and operational costs, accelerated integrations, and enabled merchants to offer major mobile wallets and local BNPL methods.

TESS — Qatar

TESS needed scalable payment infrastructure that could support Qatar’s data-localization requirements, local and international provider connections, PCI DSS certification, and future migration from SaaS to a dedicated environment.

The company initially launched through Akurateco’s SaaS platform. Akurateco supported connections to providers including MPGS, Doha Bank, and NAPS, assisted with certification, and prepared the platform for migration to Microsoft Azure infrastructure.

Outcome: TESS secured its Qatar Central Bank PSP license and PCI DSS certification, entered the market quickly, and gained high-profile clients, including a major regional telecommunications provider.

Read the complete TESS case study.

Conclusion

Building a gateway is a major infrastructure project that only makes sense for companies with sufficient payment expertise, capital, transaction volume, and long-term engineering capacity. Teams need to weigh the control and flexibility of owning the full technology stack against the cost and responsibility of operating it.

For many PSPs, fintech companies, SaaS platforms, and ISOs, white-label payment gateway software like Akurateco offers a faster alternative, combining brand ownership with ready-made provider connectivity, payment routing, reporting, fraud controls, and merchant-management tools.

FAQ

Can I create my own payment gateway?

Yes, but it’s complex. Custom payment gateway development requires extensive knowledge of payment processing, PCI DSS, security, encryption, and applicable regulatory requirements. You’ll need to integrate with acquirers, processors, and other payment providers, manage transaction routing, and ensure your system is secure and scalable.

How to set up a payment gateway?

If you’re looking into setting up a payment gateway, you’ll need to follow steps such as defining business requirements, developing core functionalities, ensuring security compliance, and integrating with financial institutions.

What licenses or registrations do you need to run a payment gateway?

The exact licenses and registrations depend on the services you provide and the countries where you operate. You may need a registered legal entity, PCI DSS certification, an acquiring bank or processor sponsorship, data-protection registration, and authorization as a payment institution or another regulated payment provider if you handle funds or provide regulated payment services.

Do I need to build a payment gateway for my website?

No. Most online businesses simply integrate an existing gateway. Custom building is mainly relevant to PSPs, fintechs, PayFacs, ISOs, and other platforms that manage complex payment flows or serve multiple merchants.

Can you build a payment gateway like Stripe?

In principle, yes. A realistic first version needs hosted checkout, tokenized card storage, recurring billing, merchant and administrative dashboards, developer APIs, reporting, and dispute handling. However, Stripe-level scale requires hundreds of engineers and direct card-scheme and financial-institution relationships, so most companies target a focused first version for specific merchants, regions, and payment methods.

Can you build a payment platform like PayPal?

Yes, in principle, but a PayPal-like platform is much broader than a payment gateway. It may require digital wallets, stored balances, peer-to-peer transfers, merchant payments, identity verification, AML monitoring, payouts, fraud operations, dispute handling, and a regulated internal ledger. Most companies begin with one focused payment product instead of recreating a global platform.

How much does it cost to build a payment gateway?

ScienceSoft estimates that building a custom payment gateway costs approximately $100,000–$300,000+, depending on its features, integrations, architecture, security requirements, and deployment model. The total investment may be higher once PCI DSS certification, infrastructure, fraud tools, provider integrations, 24/7 operations, and ongoing maintenance are included.

How long does it take to build a payment gateway?

A custom payment gateway typically takes between six and twelve months to build. Stripe cites a range of 6–12 months, while ScienceSoft estimates 6–11 months for a custom project. PCI DSS preparation, security remediation, processor certifications, card-scheme approvals, and connector integrations can extend the timeline.

How do payment gateways make money?

Payment gateways earn revenue through transaction, recurring platform, setup, and other technology-related fees. These charges are separate from interchange, scheme fees, and acquiring costs, which go to other participants in the payment chain. Providers that also offer processing or acquiring may earn additional margin from those services. 

What is the difference between a payment processor and a payment gateway?

A payment gateway securely captures and transmits payment information from the customer to the payment processor. A payment processor handles the transaction after it’s sent by the gateway, working with banks and card networks to authorize and settle the payment.

Is it hard to integrate a payment gateway?

Integrating a payment gateway can be straightforward with the right API documentation and pre-built libraries, but it can get more complex depending on your system and needs. If you require advanced features or need to comply with PCI DSS standards, the process may take more time and expertise.

How to become a payment gateway?

Becoming a payment gateway or provider means launching a payment business with the necessary licensing or sponsorship, secure infrastructure, financial integrations, compliance procedures, and merchant operations. See Akurateco’s guide to starting a payment processing company for the complete business and operational process.

Can I use a white-label payment gateway instead of building one?

Yes. White-label payment gateways provide ready-made infrastructure that can be branded as your own. For most businesses exploring how to start a payment gateway company, a white-label solution offers a faster route to market. It can also reduce operational and compliance workload, although regulatory and PCI DSS responsibilities still depend on the business model, integration, and jurisdiction.
