Overview
Taking a payment is the easy part. Getting reconciliation, refunds, failed-payment handling and recurring mandates right is where integrations usually fall short — and where the finance team ends up doing manual work every month. We build the whole flow, not just the checkout button.
Payments come in but reconciliation is manual and refunds are messy
Customers pay by UPI to a QR code or transfer to a bank account, and someone matches the credits to invoices by hand. Failed payments are not retried, refunds are processed by exception, and settlement reports never quite agree with the order list.
You will recognise this if
- Payment references are matched to invoices manually every day
- Customers pay but the order is not marked paid until someone checks
- Failed payments are simply lost rather than retried
- Gateway settlement figures do not reconcile with your own records
What you get out of it
The difference this makes
Payments confirmed automatically
Server-verified webhooks mark orders paid the moment money is confirmed, so nobody has to check a bank statement to release an order.
Reconciliation that balances
Settlement reports are matched against transactions automatically, with discrepancies and gateway fees accounted for.
Recovered failed payments
Automatic retries with an alternative method recover a meaningful share of payments that would otherwise be abandoned.
Secure by construction
Card and UPI credentials never touch your systems; the gateway handles them and you verify signed confirmations server-side.
What we build
- Integration with Razorpay, PayU, Cashfree, Instamojo or Stripe
- UPI, cards, net banking, wallets and EMI options as appropriate
- Payment links sent over WhatsApp, email or SMS for offline sales
- Signed webhook verification with idempotent handling to prevent double-crediting
- Subscriptions and recurring payments via UPI AutoPay and e-mandate
- Refunds and partial refunds with status tracking
- Automated settlement reconciliation including fee accounting
- Failed payment retry and recovery flows
- PCI-conscious design: no card data stored or logged anywhere in your systems
How it gets used
A service business collecting advances
Payment links go out over WhatsApp with the quotation; payment confirmation updates the job status and issues a receipt automatically.
A subscription product
UPI AutoPay mandates handle monthly collection, with dunning sequences for failures and automatic plan suspension on persistent non-payment.
An online store
Checkout supports UPI, cards and COD, with webhook-confirmed payments releasing orders to dispatch without manual verification.
Technology we typically use
You do not need to care about this list — but your next developer will.
- Razorpay / PayU / Cashfree / Stripe
- Python with FastAPI
- PostgreSQL
- Webhook handling with signature verification
- Idempotency keys
Timeline: Typically 1-3 weeks per gateway
