WordPress Plugin Development

Custom plugins, not plugin stacks

There's a point where adding one more plugin makes things worse. Conflicts, slow admin pages, features you pay for monthly but use 5% of, and a stack nobody can safely update. At that point a small custom plugin is cheaper and far more stable.

We write WordPress plugins the way they're meant to be written — proper OOP PHP, WordPress coding standards, hooks and filters instead of core edits, and code that a different developer could pick up in a year.

What we build

• WooCommerce extensions — custom pricing rules, checkout fields, order workflows, shipping logic
• Integrations — ERP, POS, accounting software, courier APIs, CRM systems
• Admin tools — bulk editors, reporting dashboards, import/export utilities
• Front-end features — AJAX filters, product configurators, calculators, booking forms
• Automations — scheduled tasks, webhook handlers, notification systems

How we write plugins

Every plugin follows the same structure: namespaced classes, an autoloader, separated admin and public logic, proper activation and deactivation hooks, and translations ready from day one.

• Nonces and capability checks on every request that changes data
• Prepared statements — no raw SQL string concatenation
• Sanitised input, escaped output, everywhere
• REST API endpoints where they make sense, AJAX where they don't
• Settings stored in a single option, not scattered across a dozen rows

Examples of what clients have asked for

A coupon system with rules the standard WooCommerce coupons couldn't express. A courier integration that calculates shipping by weight, zone and cash-on-delivery status. An AJAX product filter for a technical catalogue with thousands of SKUs and downloadable CAD files — that one runs on FEDS. A reconciliation dashboard that matches POS receipts against online orders.

How we quote a plugin

A plugin that does one clear thing is a very different job from one with an admin interface, settings, and an external API that occasionally misbehaves. The honest answer is that it depends on the spec.

Tell us what the plugin needs to do and we'll come back with a fixed quote and a delivery date. Whatever it costs, you get the full source code and documentation with no licence fees — it's yours to keep, extend or hand to another developer.
