Do you fix checkout bugs on staging or directly on my live store?

We reproduce and fix on staging first, every time. Checkout is the most revenue-sensitive part of your store, so we never debug live by trial and error. We confirm the fix on staging with a full test order, then deploy to production during a low-traffic window and place one real verified order to prove it works. If you have no staging environment, we set up a safe clone before touching anything.
