(02)In detail
Getting paid shouldn’t be the fragile part
Payment integrations look simple until something goes wrong: a customer pays but the order stays “pending”, a webhook fails silently, or a refund needs manual reconciliation. I integrate payment gateways with the edge cases handled — so payments, orders and bookings stay in sync automatically.
Gateways I work with
- Razorpay and PhonePe for India — cards, UPI, net banking and wallets.
- Stripe for the USA, Canada, Australia and international cards, wallets and subscriptions.
- PayPal for international buyers who prefer it.
- eWAY for Australian businesses.
- Custom bank gateways where your bank provides an API or hosted payment page.
Done properly
I use hosted or tokenised checkout flows so card data never touches your server, verify every webhook signature, and make sure each payment state — success, failure, pending, refund, dispute — updates your orders or bookings correctly. Deposits, partial payments, pay-later and recurring billing are all possible.
For any platform
Whether you run WooCommerce, a custom booking or ordering system, a membership site or a bespoke web application, the gateway is integrated cleanly into your existing flow, tested in sandbox mode end-to-end and then switched live with you.

Questions about Payment Integrations
Can’t see your question? Ask me directly — I reply within one business day.
All questionsYes. I use each gateway's hosted or tokenised checkout, so card details never touch your server, and all payments run over HTTPS with verified webhooks.
Yes — with the right gateway setup you can accept multiple currencies and show local payment methods such as UPI in India.
Webhooks confirm the real payment status. Failed or abandoned payments are marked automatically and stock or booking slots are released.
