Payment Gateway Integration

It is the work of connecting the gateway to your own system, so that when someone pays, the order is confirmed, your records update and the customer hears back.

A payment that goes through first time is the easy part. The real work is what happens when a payment fails halfway, takes a while to confirm or is attempted twice. A good integration handles those cases without your team stepping in.

Razorpay and Stripe most often. Razorpay is widely used for rupee payments through UPI, cards, net banking and wallets. Stripe is a common choice for international cards and subscriptions. We also integrate bank payment gateways where a bank or a payment type calls for it.

We recommend one based on where your customers are, how they pay and what your registration allows. The same integration can start in one currency and add others later.

Businesses adding payments to a site or app for the first time. Stores selling to customers in more than one country. Platforms that take subscription fees or pay out to partners. And teams whose checkout has a history of lost orders and confused customers, where the fix is usually in the parts nobody sees.

We map your payment journey first: what you sell, who pays, in which currencies and methods, and how orders, invoices and refunds work today. Then we list the edge cases, the rare situations that cause the most trouble: failed payments, pending payments, partial refunds, cancellations and duplicate attempts, each with the behaviour you expect. You approve the list.

We build in the gateway's test mode, where no real money moves, and run every case on the list. Webhooks are connected so your system learns the true status from the gateway, not only from the customer's browser. At go-live we follow a checklist, switch to live mode and run a real low-value payment with you.

A customer pays, sees a clear confirmation and gets an email. If their bank is slow, they see a pending message instead of a blank screen, and the order resolves itself when the payment clears. If they are charged and the page closes, the order is still created.

On your side, every payment links to an order, refunds can be issued from your admin screen, and at month end the gateway's payouts are matched to your orders, with anything that does not match flagged for a person.

• Secure by default: card details never touch your servers, gateway keys are stored as secrets and never in the code, and admin access to refunds is limited to the people who need it.
• Built to scale: the integration is built so adding a currency, a payment method or a subscription plan extends it, not replaces it.
• Tested before it ships: every payment case, including the rare ones, is run in test mode before a real customer pays.
• Looked after after launch: gateways change their rules and connections, and a Care Retainer keeps the integration current and the payout reports checked.
• Small changes handled, not invoiced: a wording fix on the checkout or a change to an order email gets done, not quoted.
• Honest advice: if your store platform's built-in checkout already does what you need, we tell you, and you skip the custom work.

If you want a payment licence or plan to become a payment aggregator yourself, that is a regulatory matter for specialist advisers. We build the technology around gateways that already hold the licences. Tax and legal questions about your payments belong with your accountant or counsel, and we flag anything we notice for them.

Payments sit in the middle of a business. If you are building a store, e-commerce development includes them. Subscription products need them inside SaaS development. Payments can start from a mobile app or from a payment link sent through the WhatsApp Business API. For how customer data around payments is protected, see Trust, Security & Compliance, where we implement and partner counsel advises on interpretation.
