Custom Plugin Solutions

If you're paying monthly for a tool that does one job, you're renting what you could own.

A custom plugin gives WordPress exactly the capability your business needs — no bloat, no conflicting third-party plugins, no recurring SaaS fee. We build to your spec using WordPress coding standards, so the result is fast, secure, and survives core and WooCommerce updates.

The benefit is ownership: documented source code you control, features that fit your workflow precisely, and an end to the monthly fees and vendor lock-in of off-the-shelf tools. We did exactly this for ATWIR — one owned plugin replacing 23+ rented automation scenarios.

What We Build

Five kinds of plugin we're asked for most

01

Custom Functionality

Bespoke features built to your exact spec — booking systems, calculators, membership logic, content engines. The capability your business needs, native to WordPress instead of bolted on with five conflicting plugins.

Built to specNative WPConflict-free
02

Admin Dashboards

Clean, on-brand admin screens and settings panels your team will actually use — data views, controls, and reports built into wp-admin so non-technical staff manage complex features without touching code.

03

Automation Plugins

Plugins that do the repetitive work for you — scheduled tasks, bulk processing, content generation, and event-driven actions. We turned 23+ fragile Make.com scenarios into one owned plugin for ATWIR.

WooCommerce Extensions

Custom checkout flows, payment gateways, shipping logic, dynamic pricing, subscription rules, and product features that stock WooCommerce can't do — built to survive store and core updates.

API Integrations

WordPress connected to the third-party services you depend on — CRMs, payment processors, shipping carriers, AI models, and internal tools — with custom REST endpoints, webhooks, and clean error handling.

That $200-a-month tool doing one job? We rebuild it as a plugin you own outright — same capability, native to your site, with no recurring fee and no data held hostage by a third party.

The checkout rule WooCommerce won't do

Conditional shipping, bundle pricing, custom fields, role-based discounts — the exact commerce logic your business runs on, built as a clean extension that survives every WooCommerce update.

Automation

Manual admin, handled by the plugin

Bulk imports, scheduled reports, content generation, and event-driven actions packaged into one plugin — so the repetitive work runs on cron instead of on someone's afternoon.

Scope My Plugin

Development Process

Specced, built, and hardened before it ships

Step 1

Spec & Scope

We pin down exactly what the plugin must do, the edge cases it must handle, and how your team will use it — agreed in writing before a line of code.

Step 2

Architecture

Clean structure, sensible hooks, and update-safe patterns designed up front so the plugin stays maintainable as WordPress and your needs evolve.

Step 3

Build

Typed, reviewed PHP and JavaScript following WordPress coding standards — the same disciplined approach behind the 21-file SEO Insights plugin.

Step 4

Test & Harden

Compatibility tested across themes, core versions, and common plugins, with error handling and security baked in — nothing fails silently.

Step 5

Maintain

Documentation, a walkthrough, and optional care plans covering updates, compatibility, and priority fixes as WordPress moves forward.

Plugin Questions

What clients ask before a custom plugin

Not sure if a plugin is the right call? Tell us what you need and we'll advise honestly.

Off-the-shelf plugins are built for the average case, not yours — so you end up stacking five of them, fighting conflicts, and paying monthly for features you half-use. A custom plugin does exactly what you need, nothing you don't, runs faster, and is code you own outright. For ATWIR we replaced 23+ Make.com scenarios with a single plugin they now own.

Simple single-purpose plugins start around $400. More involved builds — admin dashboards, WooCommerce extensions, API integrations — typically run $800–$4,000 depending on scope. Every project is fixed-price, quoted in writing before work begins. Most clients recover the cost quickly by cancelling the SaaS tools the plugin replaces.

Yes — that's the point of building it properly. We follow WordPress coding standards, use official hooks and APIs rather than fragile hacks, and test against current core and WooCommerce versions. You also get documented code, so any developer can maintain it, and optional care plans that keep it compatible as the platform moves.

Absolutely — it's one of our most-requested builds. Custom checkout flows, payment gateways, conditional shipping, dynamic and bundle pricing, subscription rules, and bespoke product features. If stock WooCommerce can't do it, we build it as a clean extension that holds up through store updates.

Yes. We build custom REST endpoints, webhooks, and integrations connecting WordPress to CRMs, payment processors, shipping carriers, AI models, and internal tools. The ATWIR Brain Engine is a plugin that orchestrates exactly this kind of API work — processing 10k+ queries a month.

Completely. You receive the full, documented source code with no vendor lock-in and no recurring licence fee. It's your plugin, on your site, that any competent developer can maintain — that ownership is the entire advantage of going custom over renting a SaaS tool.

Build It Once, Own It Forever

Stop renting features you could own outright

Tell us the SaaS tool you're tired of paying for, or the feature WordPress can't do. We'll scope a custom plugin and quote it — fixed price, in writing.
