Launch day for an ecommerce store is unforgiving — the first customers who show up either have a smooth experience or they bounce, often for good. Most of the launches that go wrong don't fail because of one big mistake; they fail because one small, boring checklist item got skipped under deadline pressure. Here are the seven that matter most.
1. Test the Payment Gateway With Real Cards
Test mode passing isn't the same as live mode working. Run a genuine small transaction through your live payment gateway before launch — including a refund — so you're not discovering a configuration issue from an angry customer's inbox.
2. Actually Complete a Purchase on Mobile
The majority of ecommerce traffic is mobile. Don't just look at the site on your phone — go through the entire checkout flow, on a real device, on real mobile data, and time how long it takes. If it's frustrating for you, it's frustrating for them.
3. Get Shipping and Tax Rules Right
Incorrect shipping costs or missing tax configuration are two of the most common reasons carts get abandoned at the last step. Test every shipping zone and rate you offer, and confirm tax is calculating correctly for your actual jurisdictions before a single real order comes through.
4. Check Page Speed, Not Just Design
A beautiful store that takes six seconds to load will lose customers before they see how beautiful it is. Run your key pages — home, category, product, checkout — through a speed test and fix anything that's obviously dragging, especially unoptimised images.
5. Set Up Abandoned Cart Recovery
The majority of carts get abandoned, that's normal — but if you have no system to follow up, you're leaving recoverable revenue on the table from day one. Even a simple automated email sequence recovers a meaningful slice of otherwise-lost sales.
6. Get Your Legal Pages in Order
Returns policy, shipping policy, privacy policy, terms of service — these aren't just legal box-ticking. Customers actively check them before trusting a new store with their card details, and payment processors often require them to be present and accurate.
7. Confirm Analytics Is Actually Tracking
Nothing is worse than running your first ad campaign or promotion and realising afterward that conversion tracking wasn't set up correctly. Place a real test order and confirm it shows up correctly in your analytics and ad platforms before you spend a penny driving traffic.
None of these seven things are hard. They're just easy to deprioritise when launch day is looming — which is exactly why they're the ones that trip people up.
Run through this list a few days before launch, not the night before — you want enough runway to actually fix anything you find, not just enough time to notice it.
