CGST and SGST or IGST
Pick your state and the place of supply. When they match, each rate is split into equal CGST and SGST halves, or CGST and UTGST in union territories without a legislature. When they differ, the whole rate is charged as IGST. The quick rate buttons are 0, 5, 18 and 40 percent.
E-invoicing and e-way bills
Businesses above the e-invoicing turnover threshold, Rs. 5 crore since August 2023, must also report B2B invoices to the invoice registration portal and print the IRN. Goods moved above Rs. 50,000 in value usually need an e-way bill. The template has fields for both numbers.
Questions
What characters can a GST invoice number use?
Up to 16 characters made of letters, digits, hyphens and slashes, unique for the financial year. The default format, such as INV/2025-26/001, fits the rule and the checks warn if yours does not.
Why does the invoice round to the nearest rupee?
Indian invoices commonly round the total and show a "Round off" line. It is switched on for India and can be turned off in the tax settings.
Can I make a GST invoice in Excel?
Yes. The Excel download keeps taxable value, CGST, SGST or IGST and the totals as formulas, so editing a quantity in Excel recalculates the tax.
