The useful starting point
A useful shop site connects a clear catalogue to records you can actually find.
Start with the right information
List a few real products with stable identifiers, prices and delivery rules. Build a cart around those records so a customer can see the total before submitting.
Put it into practice
Place one small test order. Open the site inbox and check its item quantities, contact details and timestamp. Reload the page to verify that the record was saved.
Check before you share
Move an order through the available statuses, export it and inspect the courier fields. Keep payment verification separate from delivery progress.
