Calls I made

01
Non-blocking writes
The UI does not wait for the database. Saves run in the background while staff process the next customer.
02
Service-and-product bundles
Frequent service-and-product combinations are pre-defined as one-tap packages. Faster billing, fewer errors.

Trade-offs accepted

Kept the feature scope narrow and shipped the operations that mattered.
Staff select from preset lists rather than free-text entry. Slightly less flexible, more accurate.
