Commerce platform readiness: a pre-launch checklist

Launching a commerce platform is less about the storefront looking good and more about the dozens of small things that have to work the first time a real customer pays you. This checklist covers the readiness items that are easy to skip and expensive to miss.

Test the full payment flow with real (small, live) transactions, not just the sandbox: successful payment, declined card, refund, and partial refund. Confirm the webhook that marks an order paid is verified and idempotent, so a retried notification does not create a duplicate order or double-fulfill. Make sure failed payments leave the order in a clear, recoverable state rather than a silent dead end.

Customers — and payment providers — expect a clear privacy policy, terms, a refund and shipping policy, and a real way to contact you. Show the business name and support contact prominently. These pages are not legal box-ticking; they measurably affect conversion, because a shopper deciding whether to enter card details is looking for signals that you are a real, accountable business.

Speed matters most on the pages closest to the money: product, cart, and checkout. Optimize images, cache catalog pages, and keep the checkout lean. Then test under realistic load — a launch promotion that triples traffic is exactly when the checkout must not fall over. Know your slowest page and your capacity ceiling before launch day, not during it.

Decide how inventory is decremented and what happens when two customers race for the last item. Confirm tax is calculated correctly for the regions you sell to, and that shipping options and costs are right. Make sure order confirmation and shipping emails actually send and land in the inbox — transactional email that goes to spam is a support burden and a trust problem.

Before launch, confirm backups run and have been test-restored, that you can see errors and order volume on a dashboard, and that someone knows what to do when a customer reports a problem. A store that can take orders but cannot recover from a bad deploy or answer “where is my order?” is only half launched. Readiness is as much operational as it is technical.
