The cost of the wrong extension
Is a bolted-on plugin quietly costing you sales?
If any of these feel familiar, a custom extension isn't a luxury, it's the fix. Every one of these problems is solvable with the right approach and the right team.
06 friction points we design out of every checkout
- 01
An extension built for somebody else's store
Marketplace plugins are written for the average catalog and the average checkout. The moment your pricing rules, product logic or fulfillment flow gets specific, you're stitching together workarounds around the gap.
- 02
Every added plugin taxes your checkout
Scripts, styles and extra database queries pile up fast. A bloated plugin stack is one of the quietest, most common reasons carts get abandoned before payment.
- 03
A dependency nobody's patched in years
Extensions that sit next to your payment flow are high-value targets. An unmaintained plugin isn't just outdated, it's a liability parked inside your store.
- 04
No real line to the systems you run the business on
Off-the-shelf plugins don't know your ERP, your 3PL or your accounting stack exists. A purpose-built extension closes that gap instead of leaving your team to bridge it by hand.
- 05
Checkout logic that fights how you actually sell
Generic settings screens rarely map to your pricing tiers, shipping rules or custom fields. Built-for-you logic follows your workflow, not the other way round.
- 06
Functionality you rent, never own
When checkout or fulfillment leans on a third-party plugin you don't control, one pricing change or one abandoned update can take your store down with it.

What we build
Our WooCommerce plugin development services
From a single shipping method to a multi-feature extension with custom product types and ERP integration, every project starts from a blank file.
Payment Gateway Integration
Gateway plugins built directly on the WooCommerce Payment Gateway API, wired to processors that don't already have a maintained off-the-shelf connector.
Custom Shipping Methods
Rate calculators built around your real zones, carriers and weight bands, not a flat-rate plugin forcing your logic into a shape it doesn't fit.
Custom Product Types & Pricing Logic
Bundles, subscriptions, tiered pricing and configurable products engineered as proper WooCommerce product types, never bolted-on price calculators.
Checkout Customization
Custom fields, validation and flow changes built on the Checkout Blocks API and WooCommerce hooks, so checkout stays fast and PCI-aware.
REST API & Third-Party Integration
Connections into your ERP, 3PL, accounting platform or CRM via the REST API and webhooks, so orders and stock sync without anyone touching a spreadsheet.
Admin & Reporting Tools
Purpose-built admin screens and reports on the WooCommerce Settings API, giving your team the exact read on orders, stock and customers they need.
WooCommerce Marketplace Submission
Extensions prepared against current review guidelines and submitted to the WooCommerce Marketplace, so approval isn't a last-minute scramble.
Security Hardening
Nonce verification, input sanitization, output escaping and capability checks built in before any extension goes near checkout or payment data.
Performance Optimization
Conditional asset loading, tighter queries and caching, so new functionality never comes at the cost of checkout speed.
Plugin Audit & Refactor
Existing extensions reviewed for security gaps, deprecated hooks and slow queries, then refactored to current WooCommerce standards.
Maintenance & Support
Ongoing compatibility updates for WooCommerce and WordPress core, security patches and a helpdesk that keeps checkout running while you run the business.

Why choose us
WooCommerce 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 hooks, not overrides
Every extension runs on WooCommerce's native hook system and coding standards, so it behaves predictably and keeps working through theme and core updates.
-
Security as a default, not an afterthought
Nonce checks, capability gates, 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 and queries stay tight, so your extension adds functionality without adding to checkout load time or cart abandonment.
-
Wired into your stack
We connect to your ERP, 3PL, accounting platform and APIs so WooCommerce operates as part of your business, not off to the side of it.
-
Built for how checkout actually works
Payment gateways, shipping methods and pricing rules follow how your business actually prices and ships, never 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.
-
Real overlap with your working day
Three to four hours of daily overlap with US, UK and Canada time zones, so demos and decisions happen while you're actually at your desk.
-
Built to age well
We keep extensions current as WooCommerce and WordPress release new versions, so a core update never breaks checkout overnight.

Client words
Trusted by stores that depend on their WooCommerce extensions
Our shipping rates run on weight bands and zones that no marketplace plugin ever got right. The method they built calculates it correctly at checkout, every single time.
We needed a payment gateway integration no plugin on the market covered. They built it straight against the processor's API, and checkout hasn't hiccupped since.
Wholesale pricing used to mean a manual override on every single order. The pricing logic they built now applies it automatically, and nobody has to touch it.
Questions, answered
WooCommerce plugin development FAQs
How much does a custom WooCommerce extension cost?
The cost depends on the extension's functionality, integrations and technical complexity. A single shipping method or payment gateway is simpler, while multi-feature extensions with custom product types and ERP integrations require more development. Every project is scoped and quoted individually.
How long does a WooCommerce extension take to build?
A focused, single-feature extension typically takes 2 to 6 weeks. A multi-feature build with admin interfaces and third-party integrations usually runs 6 to 12 weeks. You see a working build early, with a demo every sprint.
Can you build a custom payment gateway integration?
Yes. We build gateway plugins on WooCommerce's Payment Gateway API for processors without a maintained integration, or where the existing one is missing a feature your business needs.
Can you build custom shipping methods?
Yes. Shipping calculators built around your actual rate tables, carrier APIs or zone logic are one of the most common reasons clients come to us for a custom extension.
Will the extension work with the new Checkout Blocks?
Yes. We build checkout customizations on WooCommerce's current Checkout Blocks API rather than the legacy shortcode 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 extension. We connect WooCommerce to your existing systems so orders and inventory sync automatically.
Will the extension slow down our checkout?
We engineer extensions to load conditionally and avoid unnecessary queries, so functionality gets added without dragging checkout speed down. Performance gets tested before launch, not assumed afterward.
Can you add features to an extension we already have?
Yes. We audit the existing codebase first, flag any technical debt or security issues, then build new features on a clean foundation so they don't 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 cuts compatibility risk substantially. Our maintenance plans also cover testing and updates with every major release.
Do you handle WooCommerce Marketplace submission?
Yes. We prepare the extension against Marketplace review guidelines and manage submission, handling any reviewer feedback until the listing is approved.
Do you provide maintenance after the extension launches?
Yes. Our maintenance plans cover WooCommerce and WordPress 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're still around for version two, not just while the invoice is open.
