GST billing software for small shops, on your phone and the web

Every invoice carries what a GST tax invoice needs, laid out in the design you choose:

• your business name, address, GSTIN and logo;
• an invoice number that goes up by itself (INV-2026-0001…) and the invoice date;
• the customer's name, GSTIN and state, which sets the place of supply;
• each item with its HSN or SAC code, quantity, rate and GST rate;
• the taxable value, CGST + SGST or IGST, a round-off line and the total;
• your bank details and “Authorised Signatory”.

The Classic and Ledger designs also show the amount in words, in lakh and crore, and an HSN-wise tax summary. You can add a due date, payment terms, a vehicle number, the buyer's order number and a ship-to address.

1. Pick the customer, or add a new one with their GSTIN and state.
2. Add items. A saved product brings its price, HSN code and GST rate with it.
3. Check the tax summary: CGST + SGST for a same-state sale, IGST for an other-state sale.
4. Save, then share the PDF on WhatsApp or email, or print it.

Save each product or service once, with its HSN or SAC code, GST rate, unit (Pcs, Kg, Ltr, Box, Hour and more) and price. From then on it fills itself into every bill, so the code and rate are the same each time.

GST rates changed on 22 September 2025, and most goods now fall in the 0%, 5%, 18% or 40% slabs. Before you save an item, check its current rate with the HSN code finder and GST calculator or with your CA.

Under GST, a sale to a customer in your own state is taxed as CGST plus SGST, half each. A sale to a customer in another state is taxed as IGST. BillBabu takes the place of supply from the customer's state and splits the tax for you.

For example, ₹10,000 of goods at 18%: in your state the bill shows CGST ₹900 and SGST ₹900; to another state it shows IGST ₹1,800. The total is ₹11,800 either way.

Each sale lowers the stock of the items on it, and each purchase bill raises it. Edit or delete a bill and the stock is put right. The customer's ledger shows the new bill, the payments you record (cash, UPI, cheque, card or bank) and what is still due.

Use the Android app at the counter and the web app at app.billbabu.com on a computer, with the same mobile number and OTP. There is nothing to install on the computer. BillBabu needs internet: it does not work offline yet. PDFs, reports and payments are in the Android app. Read more about online billing on phone and PC.

BillBabu is made for kirana and general stores, hardware and electrical shops, garment shops, traders and small distributors who issue GST tax invoices. It suits shops that bill from a saved list of items: there is no barcode scanning yet. The app works in English, Hindi, Marathi, Tamil, Telugu and Kannada; bills print in English.

BillBabu makes your bills and reports. It does not generate e-invoices (IRN) or e-way bills and does not file GST returns such as GSTR-1 or GSTR-3B. Those are done on the GST portal or by your CA, who can work from the sales, purchase and monthly GST reports you share as PDF.
