A small café chooses between paper and a cloud POS that wants a monthly subscription and a working connection to take an order. The interface problem is sharper than the architecture one: the same product has to serve a cashier mid-transaction, where every extra tap is a real cost, and an owner doing the month's numbers.
Made the local store the source of truth, with CouchDB replication as an option rather than a requirement.
Modelled the menu properly — portions, add-ons and per-item routing to the right kitchen station.
Replaced the usual role dropdown with a per-screen permission matrix, so a shift lead gets exactly the screens they need.
Added shift tracking and categorised expenses, so the day closes against something.
Built backup, restore and sync configuration into the admin surface rather than a support call.
