WORDPRESS PLUGIN DEV

Custom WordPress Plugins Built for the Workflow Your Business Actually Has

Ignited Nepal builds custom WordPress plugins for UK businesses when off-the-shelf solutions create conflicts, impose limits, or simply cannot do what the workflow requires. Booking and scheduling integrations, WooCommerce B2B pricing, Salesforce and HubSpot CRM connections, membership systems, pricing calculators: each built to specification, coded to WordPress standards, and handed over with full documentation.

This is for you if

Who This Is For

You run a WooCommerce store that sells to both retail and trade customers. Your trade accounts need tiered pricing, volume discounts, and quote-based ordering that no existing plugin handles correctly without conflicting with another plugin you already depend on. You need pricing logic built specifically for your catalogue and your customer types, not a plugin that almost does it.

Your team lives in Salesforce or HubSpot. Your website lives in WordPress. Every lead that comes in through a form gets manually entered into the CRM by someone who has better things to do. You need a direct integration that maps your WordPress form fields to your CRM objects, handles deduplication, and keeps both systems current without human intervention.

You offer appointments, classes, property viewings, or service bookings with rules that no general-purpose booking plugin accommodates: staff-specific availability, location-based capacity, approval workflows, or payment structures tied to booking type. You have already tried three plugins and none of them handles your model. A custom plugin built to your specification will.

What's broken

What's Broken

Existing Plugins Conflict With Each Other

A WooCommerce store running twelve plugins is running twelve sets of code that were each written by a different team with different assumptions. Pricing plugins conflict with membership plugins. Booking plugins conflict with checkout plugins. The result is bugs that appear only in specific combinations, errors that are difficult to reproduce, and developers who cannot fix one plugin without breaking another. A purpose-built plugin with a defined scope eliminates a class of conflict.

Your Pricing Rules Are Being Maintained Manually

If your trade pricing is managed through a spreadsheet, a shared document, or manual price adjustments in WooCommerce, you have a maintenance problem that will grow as your catalogue grows. Every price change is a manual task. Every new trade customer requires a manual setup. Every exception is a workaround. A pricing plugin built to your exact trade account structure handles this automatically.

Your CRM Integration Is a Manual Data Entry Task

Contact forms that generate email notifications which someone copies into a CRM are not integrations. They are delays. Every hour between a lead submitting a form and that lead appearing in Salesforce or HubSpot is an hour where no one is following up. A direct API integration removes the delay, removes the manual step, and removes the risk of data entry errors.

Off-the-Shelf Plugins Have Functionality You Pay For but Never Use

Most commercial WordPress plugins are built for the broadest possible use case. They include settings panels, compatibility layers, and premium features that are irrelevant to your specific workflow. You pay for the licence, accept the performance overhead, and work around the parts that do not fit. A custom plugin built to scope does exactly what you need and nothing else.

What we engineer

What We Do

Plugin Specification

We document exactly what the plugin needs to do before any code is written. Functional requirements, data flows, admin interface design, API endpoints, edge cases, and acceptance criteria are all defined in a written specification. You review and approve the specification. Development begins only when the specification is agreed.

Plugin Development

We write the plugin to WordPress coding standards, following the plugin API, using hooks and filters correctly, and maintaining separation from theme code. The plugin is built to function correctly on standard WordPress hosting environments and to remain compatible with WordPress core updates.

Admin Interface

Where your plugin requires configuration or management by a non-developer, we build an admin interface inside the WordPress dashboard. Settings pages, data views, reporting, and manual override capabilities are built to the same standard as the plugin logic itself. Your team does not need to touch code to operate the plugin once it is live.

API Integration

Where the plugin connects to an external service, including Salesforce, HubSpot, booking platforms, payment gateways, or any other third-party API, we handle authentication, request formatting, error handling, and data mapping. We document the integration points and what happens when the external service is unavailable.

Unit Testing

We write unit tests for core plugin functionality. Tests cover expected behaviour, edge cases, and failure modes. The test suite is included in the source code handover so your team or future developers can extend the plugin with confidence that existing functionality remains intact.

Documentation

We produce two sets of documentation: technical documentation for developers covering architecture, hooks, filters, and database schema; and operational documentation for the team members who will use the admin interface. Both are delivered as part of the handover.

Source Code Handover

You receive the full source code, the test suite, and the documentation. You own the code. There are no licence fees, no dependency on our continued involvement to keep the plugin operational, and no restrictions on how you use or modify it.

How it works

Process

  1. 01

    Discovery and Specification

    We spend one to two weeks understanding your workflow, your existing plugin stack, the APIs of any external systems involved, and the exact functionality the plugin needs to deliver. We produce a written specification with functional requirements, data flows, admin interface wireframes, and acceptance criteria. You review and approve it before we write a line of code.

  2. 02

    Development

    We build the plugin in a local development environment, writing to WordPress coding standards with unit tests alongside the code. If the plugin involves a CRM or third-party API integration, we build against a sandbox environment before connecting to production. We share progress updates at agreed milestones.

  3. 03

    Testing and Review

    We deploy the plugin to a staging environment that mirrors your production WordPress setup. We run the test suite, perform manual testing against the acceptance criteria, and invite your team to test the admin interface and any front-end functionality. We address issues identified during this phase before the launch date.

  4. 04

    Deployment, Documentation, and Handover

    We deploy the plugin to your production WordPress environment, confirm that all functionality is operating correctly in the live context, and hand over the source code, unit test suite, technical documentation, and operational guide. We provide a 30-day period of post-launch support for issues directly related to the delivered functionality.

Common questions

Frequently asked questions about WordPress Plugin Development

How is a custom plugin different from configuring an existing plugin more carefully?

A custom plugin is written specifically for your workflow and contains only the functionality your workflow requires. An existing plugin is written for the widest possible use case, which means it includes settings, compatibility layers, and features that do not apply to you, and may handle your specific requirements through configuration workarounds rather than purpose-built logic. For workflows that are genuinely standard, a configured existing plugin is often sufficient. For workflows that are specific to your business model, a custom plugin is typically more reliable, more performant, and cheaper to maintain over time.

Will a custom plugin break when WordPress updates?

A plugin written to WordPress coding standards and using the WordPress plugin API rather than direct database access or overridden core functions will remain compatible with WordPress updates in the vast majority of cases. Breaking changes in WordPress core are rare and are announced in advance. We write to current standards precisely to minimise update-related issues, and the unit test suite we include makes it straightforward to verify compatibility before applying a major update.

Can you integrate WordPress with Salesforce or HubSpot directly?

Yes. Both Salesforce and HubSpot have well-documented REST APIs. We build the integration logic as a plugin that maps WordPress events, such as form submissions, WooCommerce orders, or user registrations, to the appropriate API calls in your CRM. We handle authentication, error logging, and retry logic for failed requests. The integration is configurable through the WordPress admin interface without requiring code changes.

How long does a custom plugin project take?

Timeline depends on the complexity of the functionality. A focused plugin for a single workflow, such as a pricing calculator or a CRM form integration, typically takes three to five weeks from specification sign-off to deployment. A plugin with a complex admin interface, multiple API integrations, or custom WooCommerce extensions takes six to ten weeks. We provide a firm estimate at the end of the specification phase, not before it.

What happens if we need to extend the plugin after handover?

Because you own the source code and receive full technical documentation, any competent WordPress developer can extend the plugin after handover. We are also available for extension work as a separate engagement. The documentation we produce is written specifically to make future development by your own team or another developer straightforward.

The Right Plugin Does Not Exist Yet. We Build It.

Off-the-shelf plugins are built for the average use case. Your workflow is not average. If you have reached the point where no existing plugin does what you need without a conflict, a compromise, or a manual workaround, a purpose-built plugin is the correct answer. Start with a brief.
