GST E-Invoicing and KYC Verification, Automated

GST e-invoicing integration is required for businesses above the e-invoicing turnover threshold -- invoices need to be pushed to the government's Invoice Registration Portal (IRP) to get an IRN and QR code before they're legally valid. This gets integrated directly into your billing/order system so an invoice is generated and registered in one step, not two separate manual ones.

PAN and Aadhaar verification API integration is the other common request, mostly from fintech-adjacent businesses, lending platforms and marketplaces doing seller/customer KYC -- confirming a PAN or bank account is genuine before onboarding someone, rather than manually checking documents.

Frequently Asked Questions

It depends on your annual turnover crossing the government's e-invoicing threshold -- if you're unsure whether it applies, that's worth confirming with your CA first; the integration itself is the same either way once required.

This is the technical integration connecting your system to the government/verification APIs -- it's not a substitute for advice from your CA or compliance consultant on whether/how the requirements apply to you.

Most projects range INR 8,000-70,000 depending on whether it's e-invoicing alone or e-invoicing plus PAN/Aadhaar/bank verification.
