Payment Gateway Integration for Razorpay, Cashfree and UPI Collections

For businesses collecting through Razorpay, Cashfree or UPI, we connect the gateway to your billing system so payments are matched to invoices, settlements are reconciled, and refunds update the same record automatically.

What Payment Gateway Integration Solves

A payment gateway confirms that money arrived, but on its own it does not know which invoice that payment was for, whether the settlement matches what was collected, or what to do when a customer asks for a refund. Integration connects the gateway's data to your billing or order system so each of those questions has an automatic answer.

What the Connection Automates

Payment Link Generation

Invoices or orders trigger a payment link or QR code automatically, sent to the customer through the channel you already use.

Payment Confirmation and Matching

A successful payment marks the correct invoice paid, using a reference that ties the transaction back to the original order even when amounts are split or partial.

Settlement Reconciliation

Daily settlement files from the gateway are checked against what your system expected, flagging the difference between what was collected and what actually reached your bank account.

Refunds and Failed Payments

Refunds initiated from your system are pushed to the gateway and the resulting status is written back, so accounts are not tracking refunds in a separate spreadsheet.

Details That Shape the Build

  • Whether you use one gateway or several, since customers on some platforms prefer different providers
  • How partial payments, part-refunds and disputed transactions should be handled
  • Whether payment links need to expire or be regenerated automatically
  • How gateway fees should be recorded against each transaction in your books

Where This Removes Manual Work

  • Accounts manually checking the gateway dashboard against a list of pending invoices
  • Customers messaging to confirm a payment that already succeeded but was not marked in the system
  • A monthly reconciliation exercise between the gateway's settlement report and the bank statement
FAQ

Frequently asked questions

Can you integrate more than one gateway at the same time?

Yes. Many businesses run Razorpay and Cashfree together, or add a second gateway as a backup, and the integration handles each transaction against the gateway it actually came through.

How are gateway fees recorded?

Fees are captured from the settlement data and posted against the transaction, so your books reflect the net amount received without accounts calculating it by hand.

What happens if a payment succeeds but the customer's connection drops before confirmation?

The gateway's own webhook and status-check are used together, so a payment that succeeded is recorded even if the customer never saw the confirmation screen, rather than relying on a single notification that might not arrive.

Do refunds still need manual approval?

That is your decision to make, not a default. We build the refund flow to match your existing approval process, whether that is automatic under a threshold or always requiring sign-off.

What drives the cost of a payment integration?

The number of gateways involved, how many payment scenarios need handling, such as full, partial, subscription and refund, and whether settlement reconciliation is included or only payment confirmation.

What sets the timeline for a payment integration?

Mostly how quickly your gateway API keys and sandbox test credentials are issued, and how much testing is needed across success, failure and refund scenarios before going live with real transactions.
