How to Create an A4 Tax Invoice
A tax invoice should clearly show supplier details, bill-to details, invoice number, date, item rows, tax summary, net amount, payment terms, and signatures.
- Enter the business name, address, email, GSTIN, and PAN.
- Add the buyer name, address, state, invoice number, invoice date, and reference number.
- Fill item rows with description, date, quantity, and unit rate. Totals calculate automatically.
- Check HSN code, SGST, CGST, payment terms, and signature labels.
- Use Print / Save PDF or Download PDF to create an A4 invoice.
Invoice Total Formula
Line total = Quantity x Unit Rate. Subtotal = sum of all line totals. SGST and CGST are calculated from the subtotal using the selected percentages. Net Amount = Subtotal + SGST + CGST.
