A WooCommerce engineer
who already knows your store.
Checkout work, custom product types, subscriptions, integrations, and the backlog you've been putting off. You get a named engineer who stays on your store instead of a different contractor every project.
Every new developer spends
the first two weeks learning
what the last one knew.
You hire a freelancer for a checkout change. They do it, they move on. Six months later something related breaks and you hire someone else, who opens the codebase cold and quotes you for the time it takes to understand a decision the last person made and didn't document.
So the cost of every change includes the cost of onboarding someone into your store, and it never amortizes. Meanwhile the workarounds pile up: a snippet in functions.php nobody remembers adding, three plugins doing what one custom field should, a checkout template forked so long ago it no longer gets updates.
The expensive part isn't the development. It's starting over every time.
WooCommerce work that
survives the next update.
Built against WooCommerce's own hooks and APIs rather than around them, tested on staging with a real transaction, and shipped with a rollback path.
Checkout and Payment Work
Custom fields, conditional shipping, tax edge cases, one-page checkout, and gateway work. The highest-risk code in your store, which is why it goes to a senior engineer and gets a real test transaction before it ships.
Product Types and Variations
Configurators, bundles, made-to-order, per-unit pricing, and variation matrices that outgrew what the admin can express. We build the product type your catalog actually needs instead of forcing it into a workaround.
Subscriptions and Memberships
Recurring billing, plan changes, proration, dunning, and gated content. Subscriptions fail quietly and expensively, so we build the renewal and failed-payment paths with as much care as the signup.
Integrations and APIs
ERP, 3PL, accounting, CRM, and email platforms wired to your store with proper error handling, retries, and reconciliation. An integration that silently drops one order in fifty is worse than no integration.
Custom Plugins and Extensions
When no extension does what you need, or the one that does brings forty features you don't want. We write focused code against WooCommerce's own hooks, so it survives core updates instead of breaking on them.
Migrations and Replatforming
Shopify, Magento, BigCommerce, or an old WooCommerce build that has been patched past saving. Products, orders, customers, and URLs moved with redirects mapped so you don't lose the rankings you already have.
Scope, build, ship.
Scope
You describe what you need in plain language. We come back with what it involves, what it touches, and what it costs, plus anything in your current setup that would make it harder than it should be.
Build
A named engineer builds it on staging against a test-mode gateway. You see progress as it goes rather than at the end, and anything near checkout, payments, or auth gets reviewed before it ships.
Ship and Keep
Deployed with a rollback path and verified against a real transaction. The engineer who built it stays on your store, so the next request doesn't start with someone relearning your codebase.
