A point of sale that fits in an apron pocket.

01 · Hardware

The cheapest POS terminal is the phone already in the shop

A traditional point-of-sale setup is a machine, a scanner, a printer, a cash drawer and somebody to install it. BillCountr needs none of it: the camera is the scanner and the phone is the terminal — and from Pro, a second counter is a second phone signed into the same shop, not another box.

• No POS machine, no dedicated scanner
• Barcode scanning through the phone camera
• A second counter is another phonePro
• The same shop on any computer you already have

02 · Speed

Scan, quantity, payment, save

The bill screen is built around the four things that happen at a counter and nothing else. Items come up from the first two or three letters or from a scan, quantity takes decimals for loose goods, the customer is only chosen when the sale goes on credit, and the payment mode is one tap. Everything downstream — stock, the customer's balance, the day's total — follows without another screen.

• Type two letters or scan the barcode
• Decimal quantities for weighed goods
• Cash, UPI, part payment or udhaar
• Print or share the moment it is saved

03 · Receipts

A thermal roll or an A4 invoice, from the same bill

The same saved bill renders as a narrow monospace receipt for a counter roll printer or as a full A4 invoice, and there are several designs to pick from. It prints through the phone or goes out as a PDF on WhatsApp, which for a lot of shops has quietly replaced printing altogether.

• Thermal receipt layout for roll printers
• A4 invoice layouts with your logo and details
• Share as a PDF on WhatsApp instead of printing
• Reprinted from the stored bill, never rebuilt

04 · Staff

More than one person billing, without more than one owner

Pro covers two people and Business five people. On Business, each person also gets a role that decides what they see — a cashier makes bills but cannot open reports or profit, or change settings. Whatever the plan, each person has their own invoice series letter, so two people billing at once produce separate consecutive series instead of competing for the same next number, even when both are offline.

• Owner, manager, cashier and auditor rolesBusiness
• A separate invoice series per person
• Every change recorded against the person who made itBusiness

A queue at the counter is the worst time to be waiting on a tower

Every bill is written to the phone before anything is sent, including its invoice number. There is no path through this where a customer waits on a network call, and no renumbering afterwards — which is what keeps a GST series consecutive in a shop that loses signal every evening.

• Billing, stock, khata and printing all resolve locally
• Invoice numbers assigned on the device
• Queued work syncs itself when signal returns
• A repeated sync cannot double a bill or a payment
