Separate POS, separate stock
The till knows what sold; the stock system finds out later, if at all.
Point of Sale that works offline, stock shared across stores and online, and daily takings posted to Accounting without a spreadsheet in between.
The till knows what sold; the stock system finds out later, if at all.
Stores move stock between each other on WhatsApp; counts drift.
Z-reports typed into accounting each evening; card settlements reconciled by hand.
We scope POS + stock + accounting for a single location first, then roll out.
