Payment Gateway Integration for Websites, Portals and Business Applications
Online payments connected to your orders, members, bookings and accounts.
BSD Infotech integrates payment gateways into websites, web applications, member portals, e-commerce and booking systems, and connects the result to the rest of the business: payment status, receipts, reconciliation and, where required, accounting in Tally. BSD has experience integrating Paytm, PayU, Stripe, CCAvenue, ICICI, HDFC, Cashfree, PayPal and Razorpay.
What Is Payment Gateway Integration?
Adding a “Pay now” button is the easy part. The real work is what happens around it: creating the payment with the correct amount and reference, verifying the gateway’s response on the server, handling payments that fail or stay pending, issuing receipts, processing refunds, and reconciling what the gateway settled with what the application recorded. That is where BSD’s software and integration background matters.
Where BSD Integrates Online Payments
E-commerce checkout
Order payment for custom e-commerce and online ordering.
Member dues & fees
Members pay outstanding dues online from a member portal, with receipts.
Bookings
Facility, venue, room or event bookings paid at checkout.
Registrations
Event, workshop and conference registration fees.
Donations
Donation websites where donors choose a cause and pay online, with automatic confirmation.
Wallet & card top-up
Online recharge of cashless or smart card balances, as in BSD’s cashless solutions.
Payment Gateways BSD Has Integrated
BSD has experience integrating the following gateways. The right one depends on the business’s bank relationships, payment methods, fees and whether international payments are needed.
| Gateway | Typical fit |
|---|---|
| Razorpay, PayU, Cashfree, Paytm, CCAvenue | Indian businesses accepting UPI, cards, net banking and wallets, depending on the gateway and account |
| ICICI, HDFC | Businesses using their bank’s own payment gateway |
| Stripe, PayPal | Businesses that need international card payments, subject to their merchant account |
BSD is not a payment gateway provider and is not presented here as a partner of these companies. Each business opens its own merchant account with the gateway it chooses; BSD integrates that account with the application. *Payment methods available depend on the gateway and the merchant account.
How a Payment Integration Works
Payment created
Amount and reference generated by the application.
Checkout
The customer pays on the gateway’s checkout.
Server verification
The gateway response is verified before anything is updated.
Status update
Order, booking or dues marked paid, failed or pending.
Confirmation
Receipt and email, SMS or WhatsApp notification, where configured.
Reconciliation
Gateway settlements matched with application records.
What BSD Covers Beyond the Payment Button
Refunds & cancellations
Refund and cancellation workflows tied to the booking or order rules.
Reconciliation reports
Reports that compare gateway transactions with application records.
Primary and alternate gateways
A second gateway configured as an alternative, where the business wants one.
Receipts
Automatic receipts that members or customers can view and download.
Accounting
Receipts and payments posted to Tally where required, through BSD’s Tally integration.
Existing applications
A gateway added to an application or website that is already running, subject to access and assessment.
Security in Payment Integrations
Integrations are designed so that card and bank details are entered on the gateway’s checkout and handled by the gateway, rather than stored in the application. Payment responses are designed to be verified on the server, using the gateway’s signature or status check, before an order or account is updated, with gateway keys kept on the server rather than in the browser. Compliance obligations such as PCI DSS belong to the gateway and the merchant; BSD does not claim PCI certification.
