The Windows app keeps an encrypted local copy of prices, customers and recent invoices. Sales are priced with the same tax engine as the server and uploaded when the connection returns.

What you get
- Same maths as the server
- The desktop app imports the server's own tax engine. Nothing is re-implemented, so the offline slip matches the final invoice.
- An OFFLINE slip
- The customer gets a slip with a provisional number. On upload, the invoice records it as its reference so you can match the two.
- Paid in full
- Offline sales are taken in full, because nothing can be refused after goods have left.
- Never silently dropped
- If a sale is refused on upload (the unit was sold elsewhere, a discount was over the limit), it stays and is flagged Needs attention.
- Returns and payments too
- Returns and customer payments queue offline the same way.
- Encrypted on the PC
- The local copy is encrypted, and the key is held in the Windows credential store.
