GST Invoice Format for Small Businesses (With Free Template)
A good invoice format makes your business look professional and helps your accountant at filing time.
Here is a simple structure that suits most small businesses.
Top section
- Your business name, address, GSTIN and contact.
- Invoice number (unique, in sequence) and date.
- Buyer name, address, state and GSTIN if registered.
Item table
List each item with description, HSN/SAC, quantity, unit price, taxable value, GST rate and tax amount. Add a total row.
Bottom section
- Total in figures and words.
- Bank details if you accept transfers.
- Terms, signature and seal.
Invoice numbering tips
- Use one series per financial year, for example ABC/26-27/001.
- Never reuse or skip numbers without a record.
- Keep a copy of every invoice you issue.
B2B vs B2C invoices
For business buyers, include their GSTIN so they can claim input tax credit. For consumers, a GSTIN is not needed, but name, address and place of supply should still be correct.
Save and share
Print the invoice or use Print → Save as PDF in your browser, then email or WhatsApp the PDF to your buyer.
Your details are remembered
Business name, address, GSTIN and logo are stored in your browser, so each new invoice only needs the buyer details and items. Nothing is saved on a server.
