What GST Verification Is Used For

B2B vendor verification

Confirm a supplier GSTIN is active and belongs to the business you think it does, before you raise a purchase order.

Invoice and input credit validation

Validate the GSTIN on an incoming invoice so your input tax credit claim is not rejected later.

Supply chain compliance

Screen a vendor master for cancelled or suspended registrations and stop transacting with them.

Business onboarding

Pull legal name, trade name, constitution and registration date to prefill a merchant application.
