Customer invoice

The customer invoice is the one the buyer actually opens — GST-compliant, with your GSTIN, the buyer's address, item details, taxes split correctly, and a signature space if your category requires it.

Customer invoice format errors are a classic returns-trap: the customer flags the invoice as wrong, the marketplace processes a return, and the deduction lands. Even when the goods were correct.

Robnu generates customer invoices alongside the packing slip and vendor invoice from one canonical order record. They stay in sync automatically — no copy-paste between three systems, no drift between print runs.
