/What it is
The point of sale and daily management of a shoe-cleaning business: pair reception, storage, payments, inventory, online booking and order tracking for the customer.
/The real problem
In a business with several cashiers working at once, two people can't mix up orders, and the total of a payment can't depend on what the customer's browser calculates.
/Decisions I made
- D-01
The server does the money calculations
Amounts are always calculated on the server and in whole cents. Any operation touching several tables is saved completely or not at all.
- D-02
Every change has an owner
Each modification is attributed to the real person who made it, not a generic user, and changes to the database cannot be altered afterwards.
- D-03
What happens when several people work at once is tested
Tests verify that two cashiers don't cross orders and that inventory stays correct even when several people change it at the same time.
- D-04
Private photos, public tracking
Photos of the pairs are private and only open through a link that expires after 5 minutes. Customers follow their order with a personal link, protected against bots.
