Custom Plugins & Integrations

Make your platforms talk to each other.

PLUGINS & APIS

Custom plugin development and seamless API integrations, including WordPress and WooCommerce. We connect your existing systems, extend their functionality, and eliminate the manual work that happens in the gaps between them.

The problem

Disconnected platforms mean double data-entry, missed updates, and manual work that quietly eats hours every week. Your tools should talk to each other, and when they don't, you pay the price.

The result

Your tools work as one connected system: data flows automatically, processes run without manual intervention, and your team stops doing the admin that your software should be doing.

What's included

Everything you need. Nothing you don't.

System & API Audit

We map your existing platforms, the data that lives in each, and the manual steps happening between them. This audit identifies where automations and integrations will have the highest impact before any code is written.

Custom WordPress Plugin Development

Purpose-built WordPress plugins that extend the platform in ways off-the-shelf plugins can't: custom post types, admin interfaces, workflow logic, and features built specifically for how your business operates.

WooCommerce Extension Development

Custom extensions that add functionality to your WooCommerce store: custom shipping rules, pricing logic, order management workflows, B2B account features, and integrations your existing plugins can't support.

Third-Party API Connections

We connect your platforms to external services via their APIs: CRMs like HubSpot or Salesforce, payment processors, logistics providers, accounting software, and any platform with a public API.

Real-Time Data Sync Between Platforms

When a customer places an order, their details should appear in your CRM automatically. We build two-way, real-time data syncs that eliminate the manual copying and reconciliation your team currently does.

Webhook Setup & Event-Driven Automation

We configure webhooks that trigger instant actions the moment something happens in one of your systems (a new lead, a completed order, a failed payment) so data flows without delay or manual intervention.

QA Testing & Error Handling

Every integration is tested for both the happy path and edge cases: what happens when an API is down, a payload is malformed, or a sync fails. Errors are caught, logged, and handled gracefully rather than silently breaking.

Technical Documentation & Handover

We document every integration we build: what it connects, how it works, what to do if it breaks, and how to extend it. Your team can maintain what we build, or hand it to another developer who's never seen the code.

FAQ

Common questions about Custom Plugins & Integrations.

Can you connect tools that don't have a public API?+

It depends on the tool. Many platforms support webhooks or data exports even without a full API. For tools with no integration options, we explore alternative approaches (screen scraping, file-based syncs, or middleware platforms like Zapier or Make) and recommend the most reliable solution.

Do I need to be on a specific hosting plan for custom plugin development?+

For WordPress plugin development, your site needs to be self-hosted (WordPress.org, not WordPress.com). For API integrations, the requirement varies by platform. We'll confirm compatibility during the discovery phase before quoting.

How long does a typical integration project take?+

Simple integrations between two platforms with well-documented APIs typically take 2–4 weeks. Complex multi-system integrations with custom data mapping and error handling can take 6–10 weeks. We provide a detailed timeline during scoping.

What happens if an integration breaks after launch?+

Integrations can break when third-party APIs change or update. We include a post-launch support period with every project, and for mission-critical integrations we recommend an ongoing monitoring retainer so we catch and fix issues before your team does.
