What happens if the power cuts mid-sale?
Each line is written to the terminal as it's added, not committed at the end. When the till powers back up it reopens the transaction exactly where it stopped, and the cashier either continues or voids it.
Do I have to take the online shop?
No. Plenty of stores run the till and back office only. The storefront can be switched on later without migrating anything, because it reads the catalogue that's already there.
How does the shop know what's really in stock?
It queries the same product tables the till writes to, so it shows true availability rather than a nightly feed. At checkout, every price and stock level is re-read from the database inside a locked transaction — the browser's numbers are never trusted, and two customers can't buy the same last unit.
Can we keep our existing hardware?
Usually, yes. TillStack drives standard ESC/POS thermal printers, USB and Bluetooth barcode scanners, retail scales and printer-driven cash drawers. Send us model numbers and we'll confirm compatibility before you commit to anything.
We have several branches. Do they share stock?
They share the catalogue and prices, but hold their own stock figures, which is how real branches work. Transfers between sites are tracked, and you nominate which branch fulfils online orders.
Who can see costs and margins?
Only the roles you nominate. Cashiers see their own session, store managers see their site, and cost, margin and group-level figures are restricted to the accounts you grant them to.
Where is our data stored, and can we get it out?
On the terminals in your stores and in the hosting region you select at sign-up. You can export everything you've put in, in full and in open formats, at any point — including after you leave.
Do you integrate with our accounting system?
Sales, purchases and reconciliation data export to the common accounting packages, and a documented API covers anything not on that list. Integration support is part of onboarding.
