GST Billing Software Development, Built for Your Counter
Off-the-shelf billing tools are fine until your business does something slightly different — a special rate for wholesale customers, a job-work invoice, a delivery challan before the bill, or a credit customer who pays in parts. We build custom GST billing software that fits the way you actually bill.
The result is a fast billing screen for the counter, a billing app for the shop owner's phone, and clean GST reports your CA can use directly.
What a good billing system should do for you
- Bill in seconds. Search or scan the item, pick the customer, done. Rates, discounts and GST (CGST/SGST or IGST) are applied automatically based on the customer's state.
- Follow the GST rules for you. HSN/SAC codes, correct tax split, e-invoice IRN and QR for eligible businesses, and e-way bill generation for goods movement.
- Track every rupee owed. Credit customers have a running ledger. Partial payments, cheques and UPI are recorded against invoices, and overdue amounts are highlighted.
- Remind customers politely. Invoices and payment reminders are sent on WhatsApp with a UPI payment link, so collections don't depend on phone calls.
- Give your CA clean data. GSTR-1 and GSTR-3B-ready summaries, sales and purchase registers, and Excel or Tally export at month end.

Frequently asked questions
Does the software generate e-invoices and e-way bills?
Yes. We integrate with a GST Suvidha Provider (GSP) API so IRN, QR code and e-way bills are generated from the invoice screen.
Can I use it on my mobile?
Yes. The owner gets a billing app for Android and iPhone to create bills, check sales and see who owes money.
How much does custom GST billing software cost?
Cost depends on your features, users and integrations, so we don't publish fixed prices. Share your requirements and we'll send a detailed quotation with scope and timeline — usually within 24 hours.
Can we move our old data from another billing software?
Yes. Customers, items and opening balances are imported during setup.
Can it print on a thermal printer?
Yes. We support 2-inch and 3-inch thermal receipts as well as A4/A5 invoices.
