A checkout problem costs sales every hour it stays live.

Checkout is the one page that can't hide behind a cache
Every other page on a WooCommerce store can be served from a cache. Checkout can't — it's dynamic and personalized by nature, so it runs the full PHP, database and JavaScript stack on every single load. That means any plugin conflict, validation bug or inefficiency there is felt directly, by every customer, with no caching layer to mask it. Most checkout problems trace back to exactly that: something running on checkout that shouldn't be, or running badly.
WHAT USUALLY DRIVES THIS
- A "security check failed" or session-expired error blocks checkout for some customers but not others
- Checkout loads slowly because a plugin is loading scripts there it doesn't actually need
- Order totals don't update after a coupon or shipping method changes, without a page refresh
- A required custom field (VAT number, delivery instructions, terms checkbox) needs adding, removing or making conditional
- The block-based checkout doesn't render an older plugin's field or payment option correctly
- Customers abandon at checkout for a mix of real reasons — unclear costs, too many required fields, no guest option — that need separating out, not guessing at
- Duplicate orders appear from a double-click, or a customer using the back button after paying
What I deliver
- Checkout error diagnosis — validation failures, redirect loops, blank/white-screen checkout
- Custom checkout fields and checkout flows built around how you actually sell
- Abandoned-cart cause diagnosis — friction, trust and technical failures separated out
- Block-based checkout vs. classic shortcode checkout compatibility
- Checkout performance — profiling and fixing a checkout that loads slowly
- Duplicate-order and totals-not-updating fixes
- Page-builder (Elementor) checkout customization
TECHNOLOGY I USE
- WooCommerce
- WordPress
- WooCommerce Blocks
- Elementor
- PHP
- JavaScript
- Query Monitor
- WP-CLI
How a checkout job runs
-
Reproduce it on the actual checkout, not a guess
A checkout error is tested against the real cart, real shipping/tax setup and real plugin stack — not a generic WooCommerce install, since the cause is usually specific to your configuration.
-
Profile what's actually running there
Query Monitor and browser network tooling show exactly which plugin, query or script is causing the error or the slowdown, instead of disabling plugins one at a time and hoping.
-
Build and test on a staging copy
Custom fields, flow changes or a checkout fix are built and tested against a copy of the real store, including a full order end to end, before touching live checkout.
-
Confirm caching doesn't break it again
Checkout needs specific cache-exclusion rules on most hosts — verified as part of the fix, not left for the next caching-plugin update to break again.
-
Ship and watch a run of live orders
Deployed with a rollback point taken first, then watched through a run of real checkouts to confirm the fix holds under actual traffic.
Who you’re working with
Building and fixing WooCommerce checkout flows under real traffic has been a recurring part of eleven years in web development — enough to know where checkout usually breaks, and where the fix actually belongs, in the plugin, the theme or the hosting layer.

Questions I get asked
Can you fix a WooCommerce checkout that isn't working at all?
Yes — a blank checkout, a redirect loop, or a "security check failed" error are each traced to their own specific cause (a plugin conflict, a caching exclusion missing, a nonce/session issue) rather than treated as one generic "checkout is broken" problem.
Do you add or remove custom checkout fields?
Yes — adding required fields (like a VAT number or delivery instructions), removing ones you don't need, conditional fields, and matching the checkout flow to how you actually sell rather than the default WooCommerce layout.
Can you help reduce cart abandonment?
I diagnose the actual cause first — a technical failure (slow load, an error partway through, an unexpected step) is a different fix from a trust or friction issue (unclear shipping cost, too many required fields, no guest checkout). I don't guess at generic "best practices" without checking which one applies to your store.
Do you work with the new block-based checkout?
Yes — setup, migration from the classic shortcode checkout, and fixing compatibility issues where an older plugin or custom field doesn't render correctly in the block-based checkout.
My checkout is slow — is that something you fix?
Yes. Checkout can't be page-cached like the rest of the site, so any plugin or script inefficiency there is felt directly. I profile checkout specifically (not the homepage) to find what's actually slowing it down.
Can you fix duplicate orders being created?
Yes — usually a missing submit-lock combined with a slow gateway response, or a customer using the browser back button after an order already went through. I fix the underlying flow, not just the symptom.
Do you customize checkout inside Elementor?
Yes — Elementor's checkout widget/template customization, matched against the store's actual WooCommerce settings so a styling change doesn't quietly break a required field or a payment step.
Is there a fixed price for checkout work?
A single checkout error or a small custom-field job is usually a fixed quote after a short look at the store. A larger checkout rebuild or an abandonment-cause investigation is scoped the same way — priced before work starts.
