The Problem

  • Fake seller registrations with invalid GSTIN or PAN numbers
  • Address entry errors during checkout increase return rates
  • Failed seller payouts due to incorrect UPI handles or bank details
  • No automated vendor KYB (Know Your Business) verification at scale

The Solution

  • Auto-validate seller GSTIN and PAN during marketplace onboarding
  • Pincode-to-address auto-fill reduces checkout abandonment by 15%+
  • Verify seller UPI handles before processing payouts — zero failures
  • IFSC validation ensures accurate bank transfer details for settlements
