What you build
Your service answers the check before payment and refuses a sale while any line carries the placeholder price, with your own sentence.
Limits
- Answered when the cashier presses Pay, not when the line is entered.
Tell the customer
A sale with a line at the placeholder price cannot be paid; the cashier is told to correct the price first.
What next
- Tell the customer the 1 limit above, and write it into the proposal.
- Follow the recipe: Several till rules in one app, with the shop's own settings (till guard rules).
- Copy the sample: S23 — Till guard rules (a check before payment and a capture on scan, one app), and change it.
- Build and test it on your sandbox (request one if you have none; what is on it).
- Run the checks: your own tests, the kit's checks and the money kit's release gate (testing and release).
- Release through the customer's own release gate (14. Testing and release); an app other shops install goes through the App library.
Test it with your service stopped: the till applies the answer you declared for when it is down.
