GST Billing Software for Small Businesses

Namma Billing is online GST billing software that makes correct tax invoices in a few clicks. Add your products once with their tax rate and HSN / SAC code, and every bill works out the taxable value, CGST and SGST (or IGST for other states), round-off and the total in words – no calculator, no mistakes.

What a Namma Billing GST invoice shows

• Your business name, address, GSTIN and logo
• Customer name, address, GSTIN and place of supply for B2B bills
• Invoice number from your own series (for example NB2026-0001) and invoice date
• HSN / SAC code, quantity, unit, rate, discount and taxable value for every item
• CGST + SGST for sales inside your state, IGST for sales to other states
• HSN-wise tax summary and amount in words on the Pro GST design
• Bank details, UPI scan-to-pay QR, terms and conditions and signature

Built for the way Indian shops bill

B2C and B2B in one place

Walk-in customers get a quick receipt; business customers get a full tax invoice with their GSTIN. You choose the customer and the software picks the right format.

Inclusive or exclusive prices

Set selling prices including GST (common for retail MRP items) or excluding GST (common for wholesale) – the tax is split out correctly either way.

Credit notes, returns and quotations

Take back goods with a sales return / credit note, send quotations and proforma invoices, and convert them into bills later.

Reports for GST filing

Sales and purchase tax reports by rate help you or your accountant prepare your GST returns every month or quarter.

Print or share, your way

Print on A4, A5 or Letter paper, on 58 mm / 80 mm thermal printers, or send the bill link on WhatsApp. Pick from ready designs – Pro Modern, Pro GST Tax Invoice, Pro Minimal, Pro Bold and Pro Thermal – and set your colour, font and logo. Learn more in GST invoice format: what must be on your bill.
