What Is a Payment Gateway?
A payment gateway is a secure software application that acts as the digital link between your website and the banks involved in a transaction. When a customer buys something from your online store, the payment gateway captures and encrypts their payment data and forwards it to your acquiring bank and payment processor. The processor checks with the customer’s bank to approve or decline the payment. Then the result comes back through the gateway, and both you and the customer see whether the payment was successful.

How Does a Payment Gateway for International Payments Work?
Accepting cross-border payments means extra steps and extra security. An international payment gateway allows you to process payments from different countries and currencies safely. Here is how it works in a few simple steps:
- Your customer places an order on your website and enters their payment details at checkout.
- The payment gateway encrypts this information to protect it from hackers and fraud.
- The payment data is sent to the payment processor, which contacts the customer’s bank to check if they have enough funds.
- The issuing bank approves or declines the payment based on the available funds and fraud checks.
- The gateway relays the response to your website and your customer sees the confirmation in real time.
- The funds are settled into your merchant account according to your payment provider’s payout schedule.
An international payment gateway also handles currency conversion, supports multiple payment methods, and stays compliant with local laws like GDPR or PCI DSS.
Payment Gateway vs Payment Processor: Know the Difference
Many business owners confuse these two terms. A payment gateway and a payment processor work together, but they are not the same.
A payment gateway is like a digital security guard that captures and encrypts payment details. It securely passes that information to the payment processor. The payment processor does the heavy lifting by routing payment data between banks and making sure the transaction is approved.
Think of the gateway as the lock on your door and the processor as the mail carrier that delivers money from your customer’s bank to yours.
Some providers combine both services, but knowing the difference will help you make better decisions when comparing payment solutions.
Understanding Payment Gateway Charges
One of the most important things to consider is how much a payment gateway will cost you. Payment gateway charges vary by provider, country, and transaction volume. Here are some common fees you should expect:
Setup Fee
Some providers charge a one-time setup fee for account creation and initial integration.
Monthly Fee
Many payment gateways have a fixed monthly subscription fee for access to their services.
Transaction Fee
Every transaction will cost you a percentage of the total sale plus a fixed fee. For example, 2.9% plus 30 cents per transaction is common for many providers.
Cross-Border Fee
When you process foreign transactions, you might pay an extra cross-border fee of around 1% to 2% to cover the additional risks and currency exchange.
Refund Fees
Some gateways charge you when you issue refunds to your customers.
Always read the fine print and compare costs when choosing your gateway. Look for hidden fees and try to negotiate better rates if your sales volume is high.
Why You Need a B2B Payment Gateway
If you run a business that serves other businesses, you need a payment gateway that handles the specific needs of B2B transactions. These transactions are often larger and may require payment terms like net 30 or net 60, invoicing options, and multiple payment methods.
A good B2B payment gateway should support high-value transactions, bank transfers, wire payments, recurring billing, and detailed reporting. It should also integrate with your ERP or accounting systems to make reconciliation easy.
By offering flexible payment options, you make it easier for your business clients to pay on time, which improves your cash flow and reduces payment friction.
What to Look For in a SaaS Payment Gateway
SaaS businesses often run on subscription models. You need a payment gateway that supports recurring billing and automated invoicing. Look for solutions with robust APIs so your development team can customize the integration and automate renewals.
A SaaS payment gateway should also allow you to accept global payments, handle currency conversions, and provide detailed analytics on churn, payment failures, and customer lifetime value. Stripe and Braintree are popular choices for SaaS companies because they are developer-friendly and support subscription billing out of the box.
The Benefits of White Label Card Payment Gateway Solutions
A white label card payment gateway lets you offer payment services under your own brand. You do not have to build the technology from scratch. Instead, you partner with a provider that has a ready-made gateway and rebrand it as your own.
This option is perfect for businesses that want to control the customer experience while using secure and proven payment technology. White label solutions are common in the fintech space and among SaaS providers that want to offer an extra layer of service to their clients.
Payment Gateway API Integration: What You Need to Know
Seamless payment gateway API integration is key if you want to provide a smooth checkout experience. APIs let you connect your website or app to your payment provider’s system. Look for a gateway with clear API documentation and good developer support.
A good API will allow you to handle transactions, refunds, chargebacks, subscriptions, and detailed reporting. It should also be flexible enough to grow with your business. If you have an in-house development team, make sure they have enough resources and access to test environments to set up and maintain the integration properly. Need help setting up?
