Stock the shelf once. Card taps on the WisePOS E and online orders land in the same feed, same stock, same totals — with zone shipping rates, low-stock flags and refunds handled. Watch the day add itself up.
0 orders — 0 at the terminal, 0 online — in one ledger. One refund netted off, VAT within already separated, and the low-stock flag is on the reorder list. Same maths, server-side, in the real product.
