Custom WordPress Development — Built Exactly How You Need It
Off-the-shelf plugins and themes get you 80% of the way. But that last 20% — the custom functionality that makes your site uniquely powerful for your business — requires development. A membership portal with specific access rules. An API integration that syncs your CRM with your WordPress user base. A product configurator that lets customers build custom orders. A dashboard that pulls data from three different sources and displays it in a format your team actually uses.
WP Ministry’s development team builds these solutions. From custom plugins and theme modifications to complex API integrations and full-site rebuilds, we develop WordPress solutions tailored to your exact requirements — then maintain them as part of your care plan so they stay compatible as WordPress evolves.
What We Build
Custom Plugins
Purpose-built WordPress plugins that add functionality specific to your business. Custom post types and taxonomies for content that does not fit standard posts or pages. Data processing and reporting tools built into your WordPress admin. Third-party API integrations that pull data from or push data to external services. Custom shortcodes and Gutenberg blocks that give your content editors new capabilities. Automated workflow triggers — when a form is submitted, when a post is published, when a WooCommerce order reaches a certain status.
Every custom plugin we build follows WordPress coding standards, includes proper security measures (nonce verification, data sanitisation, capability checks), and is designed for long-term maintainability.
Theme Customisation and Development
Modifications to your existing theme that go beyond what page builders and theme settings can achieve. Custom page templates for specific content types or layouts. Advanced conditional logic — showing different content, layouts, or calls to action based on user roles, geolocation, device type, or other conditions. Design-to-code implementation — converting a designer’s mockup into a fully functional WordPress theme or theme component. Child theme development to safely extend your parent theme without losing customisations during theme updates.
API Integrations
Connecting your WordPress site to external systems. CRM integration — syncing WordPress user data, form submissions, or WooCommerce orders with Salesforce, HubSpot, Zoho, or other CRM platforms. ERP and accounting integration — connecting WooCommerce with QuickBooks, Xero, or industry-specific business systems. Payment processor integration — implementing custom payment flows, additional gateways, or specialised checkout processes. Marketing platform integration — connecting WordPress events (signups, purchases, content views) to email marketing platforms, analytics tools, or advertising pixels. Shipping and fulfilment integration — real-time rates, label printing, tracking number injection, and fulfilment status updates.
WooCommerce Extensions
Custom ecommerce functionality that WooCommerce and its extension library do not provide out of the box. Custom checkout flows with conditional fields, multi-step processes, or industry-specific requirements. Product configurators that let customers select options, see real-time pricing, and visualise their choices. Subscription and recurring billing logic beyond what WooCommerce Subscriptions supports natively. Wholesale pricing with tiered discounts, customer-group-specific catalogues, and request-for-quote workflows. Custom shipping calculators that implement your specific shipping rate logic.
Platform Migration and Rebuild
Moving from another platform — Wix, Squarespace, Drupal, Joomla, a custom-built site — to WordPress. Or rebuilding an outdated WordPress site from the ground up with modern architecture, current security practices, and performance-optimised code. Our migration service handles the data transfer and SEO preservation. Our development team handles the custom functionality that needs to be built or rebuilt on the WordPress platform.
Our Development Process
Discovery and Specification
Every project starts with understanding what you need and why. We discuss your requirements, your business context, your users, and your constraints. From this conversation, we produce a technical specification document that details exactly what will be built, how it will work, and what it will cost. You review and approve this specification before any development begins.
Development
Our engineers build your solution on a staging environment — a private copy of your site where we develop, test, and iterate without affecting your live site. You have access to the staging environment throughout development and can review progress at agreed milestones. If something is not right, we adjust before going further.
Testing and Quality Assurance
Before deployment, every project goes through comprehensive testing. Functional testing to verify every feature works as specified. Cross-browser testing across Chrome, Firefox, Safari, and Edge. Mobile responsiveness testing across phones and tablets. Performance testing to ensure the new functionality does not degrade your site’s speed. Security review to verify that custom code follows WordPress security best practices and does not introduce vulnerabilities.
Deployment
We deploy to your live site during a low-traffic window, with a full backup taken immediately before deployment. The deployment process is scripted and reversible — if anything unexpected happens, we roll back within minutes.
Post-Launch Support
Every development project includes a support period after launch (typically 30 days) during which we address any bugs, edge cases, or adjustments that surface in real-world use. For ongoing maintenance of your custom functionality — ensuring compatibility with WordPress updates, PHP version changes, and plugin ecosystem evolution — a care plan keeps everything running smoothly long after launch.
Frequently Asked Questions
How much does custom development cost?
Every project is different. A simple custom shortcode might cost a few hundred dollars. A complex multi-feature plugin with API integrations might cost several thousand. We provide detailed quotes based on a written specification, so you know the exact cost before committing. Contact us with a description of what you need and we will provide a quote — typically within 48 hours.
How long does a typical project take?
Small projects (custom templates, simple plugins, CSS modifications) typically take 1–2 weeks. Medium projects (API integrations, complex plugins, WooCommerce extensions) take 2–6 weeks. Large projects (full site rebuilds, multi-feature systems) take 6–12 weeks or more. We provide specific timelines during the discovery phase.
Do you work with Elementor, Divi, and other page builders?
Yes. Our development team has deep experience building custom widgets, templates, and extensions for Elementor, Divi, Beaver Builder, and other major page builders. We also develop custom Gutenberg blocks for sites using the native WordPress editor.
Who owns the code you build?
You do. All custom code developed for your project is your intellectual property. We deliver complete source code, and you are free to modify, extend, or have another developer work on it in the future.
Can you maintain custom code after building it?
Yes — this is where our care plans become especially valuable. Custom code needs maintenance as WordPress core updates, PHP versions change, and the plugin ecosystem evolves. A care plan ensures your custom functionality is tested and updated alongside everything else on your site.
