However, even approved transactions can later be reversed through the chargeback process, which is governed by card network rules and enforced through issuing and acquiring banks. Once a transaction is authorized, it enters a separate phase where funds are actually transferred between institutions. This phase operates on a delayed timeline and is governed by clearing and settlement processes defined by card networks and banking systems. Various means are used to develop a merchant account; an acquiring bank creates a gateway entry to a merchant account and third-party payment services. Some merchants apply for their merchant accounts, and others aggregate with Square, PayPal, etc.

Will The Payment Gateway Integrate With Your Existing Technology?

• However, it’s essential to check with your specific payment gateway provider about their international payment capabilities, supported countries, and any additional fees that may apply for cross-border transactions.
• Marketplace payment infrastructure allows multiple sellers to connect to buyers simultaneously; often, a multi-party settlement is required.
• Transitioning to more modern solutions can often be painful for businesses, as it entails changes at all levels.
• A payment gateway is not just an API endpoint that sends transactions to a processor.

The digital payments market is booming, with e-commerce, digital wallets, and real-time payments driving unprecedented growth. Now is the perfect time to capitalize on this momentum and seize market opportunities before they pass. The legacy payment infrastructure, which was once effective, simply cannot cope with what users and businesses expect. And here, for example, cloud technologies and artificial intelligence come to the rescue, providing tools and capabilities to enhance your own products, making them more adaptive to various requests and budgets. Many gateways support international payments and currency conversion, though fees and exchange rates vary by provider.

By using multiple payment gateways, you can offer support for a range of payment methods and enable your customers to pay in their preferred currency. This approach makes your business more flexible and scalable, especially for merchants expanding globally. A gateway is responsible for authorising, encrypting and transferring online payments, while a merchant account is where your funds will be deposited after the transaction is completed. The merchant account is typically linked to your business bank account, acting as an intermediary for processing both credit card and debit card payments. After some time, after the payment is approved and fees are charged, the money will be redirected to your primary bank account. An online payment gateway uses encryption and other security measures to protect customer payment information from being intercepted by third parties.

According to the McKinsey Global Payments Map, global cross-border payments totalled approximately $179 trillion in 2024. As platforms expand internationally and offer payouts to sellers, contractors and employees worldwide, they need payment operations that handle multi‑currency, compliance and reconciliation at scale. A card swipe, wallet tap, or checkout click starts the journey—this is known as transaction initiation, the formal process of starting a payment. At this stage, the payment data is collected but hasn’t yet been approved by the bank. The specific steps might vary depending on your website’s architecture and the technology stack that you’re using. Start here for more detailed instructions about implementing Stripe payment solutions in a way that’s tailored to your needs.

If you’re a newly minted small business owner, you’ve likely heard the terms “payment gateway” and “payment processor” used interchangeably. And while most modern payment processors include a built-in payment gateway, they’re technically different. Popular gateways like PayPal, Stripe, and Square have different fees, which can also vary based on your country and transaction volume.

It connects a merchant’s website or card reader to the payment processor while gathering sensitive customer information and relaying it securely. The first step is to select a payment gateway that aligns with your business needs. Third-party payment gateway solutions are readily available common payment infrastructure errors at U.S. launch systems that small and medium merchants integrate to complete transactions.

While both models ultimately enable the same transaction flow, they differ significantly in how responsibilities and risks are distributed.

Tokenization is becoming a cornerstone of secure payment systems by replacing sensitive data with unique, non-reversible tokens. If you use platforms like Stripe, Shopify, or PayPal, the gateway is already included. For online-only businesses, hosted or API-based gateways are more suitable since you won’t have to handle in-person bank cards. With API gateways, customers stay on your website throughout the entire checkout process.

Payment gateways provide the digital infrastructure that is indispensable for enabling merchants to implement key strategic advantages like omnichannel commerce and expanded customer reach. This method isn’t common among e-commerce businesses based in the U.S., but they’re widespread in countries with lower credit card penetration. Regardless of geographic location, they’re often more complex to set up but typically boast low transaction fees.

These gateways allow developers to integrate payment processing capabilities directly into a website or app using APIs. Confirm that the gateway provider complies with PCI standards to keep your customers’ data safe. Otherwise, you run the risk of being exposed to potentially devastating data breaches and fraud. Hosted gateways redirect customers to a secure page outside your website to complete the payment. Look for customizable options that offer straightforward integration with your chosen platform for a smoother experience for both you and your customers.

Many integrated gateways use application programming interfaces (APIs), allowing developers to customize the payment experience. This flexibility enables merchants to tailor payment fields, display multiple payment options and create a branded experience that matches the rest of their website or app design. As they grow, businesses also need to plan for high volume and redundancy so they don’t have to stop working. Avoiding legacy infrastructure bottlenecks and picking payment service providers with a good track record of uptime helps keep things running smoothly. This guide provides a technical, system-level view of payment architecture, covering transaction flows, infrastructure layers, and business models such as traditional merchant accounts and Payment Facilitators.

Think of your bank as the destination for your earnings, while the payment gateway is the secure road that the payment travels on to get there. You need a bank account to receive funds, and if you’re accepting electronic payments, you typically need a payment gateway to process those transactions securely and efficiently.

What’s The Difference Between A Payment Gateway And A Payment Processor?

These are payment gateways, payment processing solutions, card networks, banks and compliance systems that keep payment info safe and protect sensitive payment data. Payment gateways operate by verifying customer payment details, ensuring adequate funds are available and enabling businesses to receive the money. This includes encrypting sensitive data – such as credit card numbers – to securely transmit information between the customer, the business and the payment processor. A payment gateway provides a way to process online transactions without directly handling sensitive customer data, such as credit card information. It securely sends and forwards the customer’s payment information — specifically encrypted payment information — to the appropriate parties for authorization.

Plans the payment gateway project (goals, timeline, budget), prioritizes the scope of work and monitors its execution, coordinates the project team, reports the progress to the stakeholders. For our project – building a Bitcoin mobile wallet on Cordova – we needed the assistance of a skilled mobile developer. ScienceSoft promptly provided us with an expert who joined our project team and quickly got up to speed with our Scrum processes. The developer quickly understood the existing code base and proceeded to modify and evolve it according to our requirements.

While some companies can develop their systems, compliance, security, and integration challenges make ready-made solutions an attractive alternative. Platforms like Akurateco provide a secure, scalable, and cost-effective payment processing solution, enabling businesses to focus on growth rather than infrastructure management. A white label payment gateway is also a third-party solution, but it is highly customisable to fit your brand, website design, and business model. This option offers businesses greater control over the payment process, more branding opportunities, and potentially lower costs.

Issuers approve or decline transactions based on sufficient funds, available funds, fraud detection rules, and account status. They are part of the system that allows secure communication between the business’s platform and the payment gateway. There is a shortcut if you cannot create your own payment gateway while white-label solutions don’t meet your needs. You can license the code of an existing payment gateway to deploy it in the preferred PCI-certified environment and change some features.

To ensure safety, payment gateways protect encrypted payment information during transmission, using protocols like SSL or TLS to secure card data from unauthorized access or theft. At its core, payment infrastructure is the collection of systems, networks and payment processing services that allow businesses to accept contactless payments online and offline. It connects consumers’ banks to merchants’ accounts, ensuring each payment transaction is authorised, processed and settled securely. A payment gateway is a technology that acts as an intermediary in electronic financial transactions, ensuring seamless processing of funds and securely authorizing transactions. It equips businesses to securely manage various payment methods, including digital wallets, debit cards, and credit cards. Payment infrastructure is an integrated network of technologies, systems, and processes that enable modern financial transactions.

The United States has a variety of payment rails that function with slightly different settlements and applications. Immediate authorisation is in place to prevent fraud and ensure that scammers can only attempt to steal a limited number of times, while settlement occurs to guarantee that the correct value is wired to the seller. The MT/ISO cross-border coexistence period ended⁠ in November 2025, retiring legacy MT messages for cross-border payments, with structured-address and reporting requirements following through 2026 and 2027. Smart retries on soft declines, issuer-aware routing, and domestic processing where possible are not configured once and left alone — they need revisiting as provider performance shifts and new markets open. After Stripe processes the payment request, you’ll receive a response on your server. If your project is successful, the number of transactions it will handle will grow.
