Off-the-shelf extensions that almost fit
Most WooCommerce extensions are built for the average store. When your checkout, shipping or product logic needs something specific, you end up stacking workarounds around the 20% it gets wrong.

The cost of the wrong extension
Is an off-the-shelf extension creating more problems than it solves?
If any of these feel familiar, a custom extension is not a luxury, it is the fix. Every one of these problems is solvable with the right approach.
Plugin bloat slowing checkout down
Every extra extension adds scripts, styles and database queries. Poorly written WooCommerce plugins are one of the most common causes of slow checkout and abandoned carts.
Security vulnerabilities from unmaintained extensions
Popular WooCommerce extensions are high-value targets, sitting right next to your payment flow. An abandoned or carelessly built extension becomes a liability inside your store.
No real connection to your other systems
Off-the-shelf extensions do not know about your ERP, your 3PL or your accounting software. A custom extension connects WooCommerce to the rest of your business stack properly.
Checkout and product logic that fights your workflow
Generic settings pages rarely match how your store actually operates. A custom extension is built around the exact pricing rules, shipping logic and checkout fields your business needs.
No ownership of functionality your store depends on
When checkout or fulfillment depends on a third-party extension you do not own, a pricing change or an abandoned plugin can break critical functionality overnight.

Why choose us
WooCommerce plugin development done the right way
Anyone can write PHP that hooks into WooCommerce. We engineer extensions that are secure, lean, compatible with the next core update and fully owned by you, then stay around to maintain them.
Start your project-
Built on WooCommerce hooks, not overrides
Every extension uses WooCommerce's native hook system and coding standards, so it behaves predictably and survives theme and core updates.
-
Security by default
Nonce verification, capability checks, sanitization and escaping sit next to your payment flow from day one, not bolted on after a review flags a problem.
-
Lean by design
Assets load conditionally. Queries are optimized. Your extension adds functionality without adding to checkout load time or cart abandonment.
-
Connected to your stack
We integrate with your ERP, 3PL, accounting platform and APIs so WooCommerce becomes part of your operation instead of sitting outside it.
-
Built for real checkout logic
Payment gateways, shipping methods and pricing rules are built around how your business actually prices and ships, not a generic flat-rate template.
-
You own the code
Full IP assignment on every contract. The extension belongs to you outright, with no recurring licence fee on your own functionality.
-
Overlap with your hours
Three to four hours of daily overlap with US, UK and Canada time zones, so demos and decisions happen in your working day.
-
Long-term compatibility
We keep your extension updated as WooCommerce and WordPress release new versions, so a core update does not break checkout overnight.

Client words
Trusted by stores that depend on their WooCommerce extensions
Our shipping rates depend on weight bands and zones no off-the-shelf plugin handled correctly. The custom method they built calculates it exactly right at checkout, every time.
We needed a payment gateway integration that no plugin on the market supported. They built it directly against the processor's API and checkout has not had an issue since.
Tiered pricing for wholesale customers used to need a manual override on every order. The custom product logic they built applies it automatically and nobody touches it anymore.
Questions, answered
WooCommerce plugin development FAQs
How much does a custom WooCommerce extension cost?
Most custom extension projects land between $3,000 and $35,000 depending on complexity and the number of integrations. A focused shipping method or single payment gateway sits at the lower end; a multi-feature extension with custom product types and ERP integration sits higher. Every quote is itemized before work begins.
How long does a WooCommerce extension take to build?
A focused single-feature extension typically takes 2 to 6 weeks. A multi-feature extension with admin interfaces and third-party integrations usually runs 6 to 12 weeks. You see a working build early and a demo every sprint.
Can you build a custom payment gateway integration?
Yes. We build payment gateway plugins on WooCommerce's Payment Gateway API for processors that do not already have a maintained integration, or where the existing integration does not support a feature your business needs.
Can you build custom shipping methods?
Yes. Custom shipping calculators built around your actual rate tables, carrier APIs or zone logic are one of the most common reasons clients commission a custom WooCommerce extension.
Will the extension be compatible with the new Checkout Blocks?
Yes. We build checkout customizations on WooCommerce's current Checkout Blocks API rather than the legacy shortcode-based checkout, which is the supported path going forward.
Can the extension connect to our ERP, 3PL or accounting software?
Yes. REST API and webhook integration is one of the most common reasons clients commission a custom WooCommerce extension. We connect WooCommerce to your existing business systems so orders and inventory sync automatically.
Will the extension slow down our checkout?
We engineer extensions to load conditionally and avoid unnecessary database queries, so functionality is added without dragging down checkout speed. Performance is tested before launch, not assumed.
Can you add features to an extension we already have?
Yes. We audit the existing codebase first, identify technical debt or security issues that need addressing, then build new features on a clean foundation so they do not introduce instability.
Will the extension stay compatible when WooCommerce or WordPress update?
We code to current WooCommerce and WordPress APIs rather than deprecated hooks, which significantly reduces compatibility risk. Our maintenance plans also include testing and updates with each major release.
Do you handle WooCommerce Marketplace submission?
Yes. We prepare the extension to meet WooCommerce Marketplace review guidelines and handle the submission process, addressing any reviewer feedback until the listing is approved.
Do you provide maintenance after the extension launches?
Yes. Our maintenance plans cover WooCommerce and WordPress version compatibility, security patches, bug fixes and a monthly bucket of improvement hours, with most issues resolved overnight your time.
What happens after the extension launches?
Every project includes a handover, documentation and a warranty window for fixes. Most clients move onto a maintenance plan so the extension stays current as WooCommerce evolves. We are still available for version two, not just while the invoice is open.
