Counterzap Fast GST billing counter for retail shops, with AI sales insights
A browser-based billing counter for small retail shops. Add products, tap or scan them into a bill, apply discounts and GST, print the receipt, and see what sold at the end of the day.
What Counterzap does
- Tap, search or scan billing
- Product tiles with price and stock, a search box that accepts barcode scanners, and category filters to find items quickly.
- GST handled on every bill
- Per-product GST rates of 0, 5, 12, 18 or 28 percent, with prices that either include GST or have it added on the bill.
- Discounts and round-off
- Give a bill discount in rupees or percent. The total is rounded to the nearest rupee and the round-off is shown.
- Printable receipt
- A narrow receipt with shop name, address, GSTIN, items, CGST and SGST breakup and your footer line, ready for a thermal or normal printer.
- Stock and low-stock alerts
- Stock reduces with each sale and returns when a bill is cancelled. Set an alert level per product to see what is running low.
- Daily sales report
- Sales by day or hour, top products, categories, payment modes and a GST summary for today, 7 days, 30 days, this month or any dates.
- AI sales insights
- A written summary of what sold, patterns by day and payment mode, and suggested actions, based on your own bills.
- AI reorder suggestions and questions
- Ask what to reorder or type your own question about sales and stock, and keep the answers saved.

- Import your product list from a CSV file and export products, bills, bill items and the GST summary at any time.
How it helps
Counterzap turns any laptop, tablet or phone into a billing counter. Your products appear as large tiles you can tap, search by name, or scan in with a barcode scanner. Quantities, discounts, GST and round-off are worked out for you, and the bill prints as a narrow thermal-style receipt with a CGST and SGST breakup.
Every bill reduces stock automatically, and products that fall to their alert level show up on the Today screen. If a bill was made by mistake you can cancel it and the stock goes back. Loose items sold by weight work too, because quantities can be decimals such as 0.5 kg.
The report screen shows sales by day or by hour, top products, category split, payment modes and a GST summary by tax rate for any date range. Bills, bill items, products and the GST summary can each be downloaded as CSV.
The AI insights screen reads your last 30 days of bills and current stock. It can write a plain-language summary of what is selling, suggest what to reorder and how much, and answer questions you type about your own sales. Everything else works without AI.

Questions about Counterzap
How much does Counterzap cost?
There is a free plan, a Starter plan at Rs 399 a month and a Pro plan at Rs 999 a month. The plans differ in how many products you can keep, how many bills you can make each month and how many AI requests are included.
What can I do on the free plan?
The free plan lets you keep up to 40 products, make up to 100 bills a month and use 10 AI requests a month. All screens, receipts, reports and exports are included.
Can I export my data?
Yes. Products, bills, bill items and the GST summary can each be downloaded as CSV files from the Settings and Reports screens, on every plan.
Does it work on a phone or tablet?
Yes. The counter, bills and reports adapt to phone and tablet screens. On a phone the product tiles sit above the bill, with a bar at the bottom showing the running total.
Do I need a barcode scanner or a special printer?
No. You can tap or search products without a scanner. If you have a USB or Bluetooth scanner that types like a keyboard, scan into the search box and the item is added. Receipts print through your browser to a thermal or normal printer.
How is GST calculated?
Each product has its own GST rate. In Settings you choose whether your prices already include GST or GST is added on the bill. Receipts and the GST summary split the tax equally into CGST and SGST. IGST for inter-state sales is not covered.
Is the AI required to use the app?
No. Billing, stock, reports and exports work without it. AI insights are an extra that read your own sales data when you ask for them, within your plan's monthly allowance.
