How to make a GST invoice

With BillEasy you can create a GST invoice in three steps: (1) fill in your business details and GSTIN, (2) add your customer and their state, and (3) add line items with quantity, rate and GST rate. The tool automatically calculates the taxable value, the tax split (CGST + SGST or IGST), the grand total and the amount in words, and renders a clean invoice you can download as a PDF or print.

What a GST invoice must contain

Under the GST law, a tax invoice issued by a registered supplier should generally include:

• Name, address and GSTIN of the supplier (your business).
• A unique, consecutive invoice number and the date of issue.
• Name, address and GSTIN of the recipient (if registered).
• HSN code for goods or SAC code for services.
• Description, quantity, unit and taxable value of each item.
• Rate and amount of tax split into CGST, SGST/UTGST or IGST.
• The total invoice value, and a signature or digital signature of the supplier.

CGST/SGST vs IGST — which one applies?

The tax split depends on the place of supply. For an intra-state sale (supplier and customer in the same state), the GST is split equally into CGST (Central GST) and SGST (State GST) — for example, 18% GST becomes 9% CGST + 9% SGST. For an inter-state sale (different states), a single IGST at the full rate applies instead. In BillEasy, just use the "Same state (CGST + SGST)" toggle to switch between the two.
