What you need to know
A store is ready when customers can find an item, understand the offer, pay, receive a correct confirmation, and get help. Test operations, not only the homepage.
How to apply it
Verify stock and options, shipping, payment outcomes, receipts, policy pages, analytics events, and staff access. Run the full order flow in a safe test environment.
Common mistake to avoid
One successful test payment leaves cancellations and failed notifications undiscovered. Check the whole order lifecycle.
