Most launch-day problems aren't design problems - they're small settings nobody double-checked. A missing shipping zone, a broken discount code, a checkout that was never tested with a real card. Each one is minor on its own, but on launch day, with real traffic arriving and no room to quietly fix things, they turn into lost sales and support emails all at once.
Launch day is the worst time to discover your checkout doesn't work on mobile.
Working through a short checklist a day or two before launch catches almost all of it - here's exactly what to check, and why each one matters.
The Pre-Launch Checklist
- Place a real test order with an actual card to confirm checkout and payment processing work end to end
- Test your homepage and product pages on an actual phone, not just a resized browser window
- Double-check shipping rates and delivery zones for every region you plan to sell to
- Set up analytics and conversion tracking before your first visitor arrives, not after
- Proofread your shipping, returns and contact pages - these get more traffic than most stores expect
Why a Real Test Order Matters More Than a Preview
Most platforms let you preview checkout without actually charging a card, but a preview skips exactly the parts most likely to break: real payment processing, real tax calculation, and the real confirmation email a customer receives. Placing one genuine order, refunded afterward if needed, is the only way to confirm the full path actually works.
Don't Skip Analytics Setup
It's tempting to launch first and "add analytics later once things are running." The problem is that your first wave of traffic - often your most engaged, from friends, social followers or an initial ad push - is also the data you'll never get back if tracking wasn't running yet. Set up conversion tracking before launch, not after the first sale surprises you.
Double-Check Your Discount and Email Automations
A welcome discount code that's misspelled, expired, or set to the wrong percentage is one of the most common launch-day complaints - and one of the easiest to prevent with a single test signup. The same goes for abandoned cart and order confirmation emails: send yourself a real test of each so you know exactly what a customer sees, rather than assuming the default settings are correct.
Confirm Your Legal and Policy Pages Are Real
Placeholder privacy policies and terms pages are easy to forget about once the rest of the store looks finished. Beyond the trust impact, some ad platforms and payment processors specifically check for genuine, complete policy pages before approving an account - a placeholder page can quietly block advertising or payment approval right when you need it most.
The Pages Nobody Thinks to Check
Shipping, returns and contact pages get far more traffic than most new store owners expect, especially in the first few weeks when customers are still deciding whether to trust a new brand. A shipping page with placeholder text, or a returns policy that was never filled in, quietly undermines trust at exactly the moment a hesitant buyer is looking for reassurance.
It's also worth revisiting common mobile checkout friction points specifically during this test, since checkout issues are the most expensive thing to discover after launch rather than before it.
None of these take long individually, but skipping them is how a promising launch turns into a week of cleanup instead of a week of sales.

Frequently Asked Questions
How far in advance should I run through this checklist?
One to two days before launch is usually enough - close enough that nothing changes before go-live, but early enough to fix anything that comes up.
Do I need to test shipping to every country I plan to sell to?
At minimum, test your top few markets and spot-check the rest - shipping rate errors are common and easy to miss without checking multiple regions.
What's the most commonly skipped item on this list?
Placing an actual test order with a real card - many store owners rely on a checkout preview instead, which doesn't reveal payment processing issues.
Should I soft-launch before a full announcement?
It's a reasonable approach - a small, quiet launch to a limited audience can surface issues before you send traffic from a bigger campaign or announcement.
