In Zoho Books, go to Sales, then Invoices, and click New Invoice. Select the customer: their GSTIN, GST registration type, and billing address auto-fill from the customer record. Add line items, selecting each item from your Item Master or typing a new description. Assign the correct GST rate (0%, 5%, 12%, 18%, or 28%) to each line. Zoho Books determines whether the transaction is intra-state (CGST + SGST) or inter-state (IGST) based on the comparison of your organisation’s state and the customer’s billing state.
Zoho Books auto-generates sequential invoice numbers using your configured prefix and format (for example, INV-2024-001). For GST compliance, every B2B invoice must include the customer’s GSTIN, your GSTIN, the invoice date, HSN or SAC codes for each line item, the taxable value, the GST amount split by tax type, and the total amount. Zoho Books includes all these fields by default in its invoice template.
For businesses with annual turnover above the e-invoicing threshold (currently INR 5 crores), Zoho Books generates the Invoice Reference Number (IRN) and QR code by submitting the invoice to the GST portal’s Invoice Registration Portal (IRP) directly. Once the IRN is generated, the e-invoice is legally valid and must not be modified. Zoho Books stores the IRN and QR code against the invoice record automatically.
An invoice in Zoho Books is a billing document raised to a customer requesting payment for goods delivered or services rendered. It records revenue, calculates applicable GST, and updates Accounts Receivable automatically.
Go to Sales, then Invoices, click New Invoice, select the customer (GSTIN and GST treatment auto-fill), add line items with HSN or SAC codes, and Zoho Books calculates the correct CGST, SGST, or IGST. Save and send via email.
