Know your shop’s real profit in 3 steps, through LINE

August 5, 2026 · by Posless Team

Many shop owners hit the same problem: busy selling all day, but when asked how much profit is actually left, they can’t answer. There’s no time to jot down income and expenses, and purchase receipts pile up in a drawer.

Posless makes this much easier, in just 3 steps through LINE:

1. Pick what you sold

Add your products (name, price, cost), then log a sale easily: tap “Log sale” and pick a product and quantity, or type in LINE like “sell coffee” · sell several at once with commas, like “sell coffee 2, tea 1, water 3”. The system records the sale and works out real profit instantly, with no long data entry.

2. Snap a receipt = cost

When you buy stock for the shop, send a photo of the receipt and AI reads the items and total automatically, then logs it as cost. You just confirm it’s correct before saving.

3. Know your real profit, every day

One tap shows your real profit = sales − cost by day, week, and month, with a clean summary card you can share on social to show off your numbers.
