Questions

Does it work without internet?

Yes. Sales are recorded on the till and sync when the connection returns. Receipts print with their real invoice number at the time of sale, because each till reserves a block of numbers in advance.

What happens if stock goes negative after an offline sale?

The sale is accepted and flagged for you to check. The goods have already left the shop, so refusing the sale afterwards would not put them back — instead you get a discrepancy to reconcile with a physical count.

Can my staff see what things cost me?

No. Cost prices, margins and profit are visible to admins only, and that is enforced on the server — the figures are never sent to a sales account in the first place.

How is profit calculated?

Revenue minus the cost of the goods sold, minus expenses you record such as rent and salaries. Item cost uses a weighted average that updates each time you restock, and the cost is frozen onto each sale so changing a price later never rewrites past profit.

Can I run more than one shop?

Each shop is separate, with its own stock, staff and books. One person can hold an account at more than one shop.

Does it work with a barcode scanner?

Any USB scanner that types like a keyboard works with no setup. You can also type an item code by hand if a label is damaged.

What about my existing data?

You start fresh. Adding items as you restock is usually quicker than importing a list that has drifted from what is on the shelves.
