Know who you are doing business with

Wrong or inactive GSTINs cause rejected input tax credit, failed invoices and onboarding fraud. A GST verification step at the right point in your workflow prevents these problems.

Where to use it

  • Vendor and distributor onboarding — verify before you create the account.
  • B2B checkout — auto-fill business name and address from the GSTIN.
  • Invoicing — validate buyer GSTIN before generating a tax invoice.

What we integrate

GSTIN format and checksum validation, lookups through authorised GST data providers (legal name, trade name, registration status, registered address and taxpayer type), caching to avoid repeat costs, and clear error handling in your user interface.
