Ecommerce Checkout Not Working

Higher-risk issue — be cautious and consider professional help sooner.

Customers can't complete a purchase — the cart, checkout, payment, shipping, tax, or confirmation step fails.

Common signs of this issue

Safe checks you can do yourself

None of these require sharing passwords with anyone.

What this usually means

Checkout failures usually trace to a payment gateway misconfiguration or outage, a plugin/app conflict after an update, or a shipping/tax rule that blocks completion. Missing confirmation emails are a separate deliverability issue.

Because real money and customer trust are on the line, store issues deserve careful, prompt handling.

What not to do

When to get help

A broken checkout is directly costing you sales, and payment settings are easy to get wrong. This is one of the clearest cases for prompt, careful help — ideally tested so you're not debugging on live customers.

Not sure what to do next?

Answer a few short questions and we'll point you to the safest next step — DIY, a freelancer, or a direct review. No passwords required.

Is this a business website? If this issue may be costing you leads, sales, or trust, you may want a direct review instead of trial and error.

Frequently asked questions

Orders work but customers get no confirmation — why?

The checkout itself is fine; the email is failing. That's the same deliverability issue covered in the email guides — usually fixed by sending through an authenticated mail service.

How do I test checkout without real charges?

Most platforms and payment providers offer a test/sandbox mode. If not, a small real purchase you refund afterward can confirm the full flow.
