GST E-Invoicing Setup in Zoho Books

GST E-Invoicing is mandatory for businesses with annual turnover above Rs. 5 crore. Every B2B invoice must be registered on the Invoice Registration Portal (IRP) to get an IRN and QR code. Zoho Books accounting and GST features automates this so your team does not visit the IRP portal manually for each invoice.

What Is GST E-Invoicing?

E-Invoicing means registering each B2B invoice on the government IRP before sharing it with the buyer. The IRP validates the data, generates a unique IRN, digitally signs it, and returns a QR code. The registered invoice auto-populates into filing GST returns with Zoho Books and the buyer’s GSTR-2A/2B.

Setting Up E-Invoicing in Zoho Books

Go to Settings > Taxes > GST Settings > E-Invoicing. Authenticate with the IRP using your E-Invoice API credentials. After setup, every B2B invoice is registered in real time when you confirm it.

The E-Invoicing Flow

1. Create a B2B sales invoice
2. Confirm it and Zoho Books sends JSON to the IRP
3. IRP validates, generates IRN and QR code
4. Zoho Books stores both on the invoice record
5. The PDF now includes IRN and QR as required by law

Handling Amendments and Credit Notes

Credit notes against E-Invoiced invoices must also be registered on the IRP. Zoho Books handles this automatically. E-Invoices can be cancelled within 24 hours; after that, issue a credit note instead.
