Checkout not completing, or payment errors
Orders failing at the last step are the most expensive bug on any store. Usually a gateway configuration, SSL, or plugin conflict at the point of payment.
Checkout errors, payment gateway failures, shipping and stock miscalculations diagnosed and fixed, tested with real transactions before I call it done.

WooCommerce is not one system, it is WordPress plus a payment gateway plus a shipping and tax rule engine, usually with a caching layer sitting on top of all three. Checkout is the one moment every part of that chain has to work correctly at the same time, which is exactly why it is the most common place things quietly break.

Wrong rates, zones not applying, or tax miscalculating at checkout. I audit the rule configuration rather than just resetting it and hoping.
Variations missing, stock showing available when it is not, or products not appearing in the catalog. Usually a sync, cache, or attribute configuration issue.
A store that works fine in testing but buckles during a sale or a traffic spike. I look at hosting, caching and plugin load together, not just one of them.
Which step breaks, for which customers, and since when. A failed order or a screenshot of the error is enough to start.
WooCommerce’s own status logs, the gateway’s transaction log and the PHP error log get read together, since a checkout failure usually leaves a trace in more than one of them.
I reproduce the issue on a staging copy or with test transactions, isolating whether it is the gateway, a plugin conflict or a configuration setting, so live orders are never put at risk during diagnosis.
A full backup of the store database and files is taken before anything changes, since checkout and payment settings are not somewhere to guess.
The confirmed cause gets corrected — a gateway setting, a rule, a conflicting hook — on staging first.
The fix is tested against actual checkout flows, not just the sandbox, including the specific payment methods your customers use.
Most storefront traffic checks out on a phone, so the cart and checkout flow get tested on mobile specifically, not just confirmed on desktop.
SSL, API keys and any exposed endpoints get checked, along with a look at whether the fix added any drag to page load at checkout.
Deployed during a safe window with a rollback point taken first, then watched through at least one full order cycle to confirm it holds under real use.
Running and fixing WooCommerce stores has been a recurring part of eleven years in web development — checkout failures rarely surprise me, because I know where gateways, caching plugins and shipping rules tend to collide, having hit most of those collisions before.
Yes, this is one of the most common jobs I get. I check the gateway configuration, SSL, plugin conflicts and the checkout flow itself, then test with real transactions to confirm the fix actually works.
Yes, and most of the major WooCommerce payment gateways. If you use a less common regional gateway, tell me which one and I will confirm before starting.
Yes. These are usually a rule configuration issue rather than a bug in WooCommerce itself, and I audit the actual rules against what you intend to charge.
Yes, and if you have a specific date coming up, tell me early. Fixing an issue before a major traffic spike is a different priority than fixing it after.
Yes, core, plugin and gateway updates, plus monitoring, on a monthly arrangement. Plenty of store owners bring me in for the initial fix and then handle updates in-house afterward. See WordPress Maintenance for plans and pricing.
That is fine, most people who contact me are in that position. Describe what you have noticed and I will run a proper diagnostic to find the actual cause.
No — a fix targets the specific broken function, such as a gateway, a shipping rule, or a plugin conflict, not your orders or customer records. I also test on a staging copy first specifically so live order data is never at risk.
Small, well-defined issues are usually quoted as a fixed price once I’ve seen the error. Unclear or intermittent issues start with a paid diagnostic so neither of us is guessing at scope.
