Payments & GST e-Invoicing Integration, done properly
UPI treated properly
As the primary method most Indian customers use, not an option listed under cards.
IRN and signed QR
Registered with the IRP at billing time and printed on the face of the invoice.
Survives portal outages
Queues and retries rather than losing the sale or printing something invalid.
Cancellation handled
Inside the window it cancels; outside it, a credit note. Staff cannot simply delete a registered invoice.
Why it matters in Mangaluru
Mangaluru businesses and payments & gst e-invoicing integration.
Mangaluru has the concentration of B2B trade where e-invoicing stops being a compliance detail and becomes an operational one. Above the threshold every B2B invoice must be registered with the portal at the moment of billing, and an invoice that missed its window can never be made valid.
UPI treated properly
We build it into your billing so it happens at the counter, with a retry queue for when the portal is unavailable — because a Mangaluru distributor cannot stop dispatching while a government service has a bad afternoon.
Refunds and reconciliation
Including partial refunds and settlement matching, which is where most integrations quietly break.
Stored, not just printed
IRN, acknowledgement number and QR payload kept in your database where they belong.
