Solutions · Business software
Billing that keeps up with the queue at the counter.
A kirana at 7 pm has no time for a slow screen. We build billing apps that print a GST invoice in seconds, keep the customer credit book honest, and tally cash and UPI at closing — for one shop or a chain.
Who it's for
If this sounds like you.
- Retail chains and distributors who want their own billing system
- Software companies building a billing product for small merchants
- Franchise brands that need the same counter in every outlet
- Wholesalers with credit customers and supplier orders
Every side of the product

Questions
About your gst billing app.
What does custom billing software cost?
It depends on the number of stores, devices and reports you need. Every project gets a fixed quote within 48 hours of your brief. Our guide to app development cost in India explains typical ranges and what moves them. A single-store counter app costs far less than a multi-store system with stock transfers and accountant exports.
Will billing work without internet?
Yes, if you need it to — and most shops do. The counter app stores bills on the device, keeps printing receipts, and syncs to the owner's console when the connection returns. We design the rules for conflicts, such as two counters selling the last packet of the same item.
Does it work on a basic Android tablet?
Yes. We build for the low-cost Android tablets and phones shops actually buy, with large tap targets, quick item buttons and screens that stay fast with thousands of products. Receipt printers, barcode scanners and cash drawers are tested with the actual models you plan to buy, before launch rather than after.
Can it send GST e-invoices?
We can integrate with the government e-invoicing system through an authorised provider if your business is required to issue e-invoices. Your accountant should confirm which rules apply to your turnover; we build the flow and the reports to match. Smaller shops that don't need e-invoicing still get clean GST invoices and reports.
Who owns the software?
You do. Source code, designs and documentation are handed over in full, so you can run it, sell it or extend it with your own team. There is no per-store licence fee to us, and your sales data lives in your own database and cloud account.
