Frequently Asked Questions

Troubleshooting & Common Government Rejections

Why do I need separate GSP credentials instead of my main GST portal password?

The Government of India (NIC) strictly mandates using API / GSP sub-user credentials for third-party billing software. This protects your main tax account security so your master admin password is never shared, and allows you to revoke or regenerate API access anytime without affecting your main tax filings.

Is there any government fee to create GSP credentials?

No. Generating GSP API credentials on ewaybillgst.gov.in and einvoice1.gst.gov.in is 100% free of cost provided by the National Informatics Centre (NIC).

What if I get the error 'Invalid GSP credentials' in ClayBill?

This usually happens if the 3-character suffix was typed incorrectly or if a different GSP name was selected during registration. Verify that 'GSTZen' was chosen as the GSP provider on the government portal, and check that the username prefix matches.

Who is required to generate E-Way Bills vs E-Invoices?

E-Way Bills are mandatory for all ceramic tile consignments where invoice value exceeds ₹50,000 (interstate) or state-specific threshold. E-Invoicing (IRN) is mandatory for businesses with aggregate turnover exceeding ₹5 Crores in any preceding financial year for B2B transactions.

Can the ClayBill support team generate these credentials for me?

Because the government portal requires an OTP sent to your registered mobile number, you or your accountant must click the OTP button. However, our support team can join a live WhatsApp video call or screen-share to guide you through every single click in under 3 minutes.
