Custom WordPress Plugin Development for Businesses That Need More Than Off-the-Shelf Solutions
Custom WordPress plugins built from scratch to WordPress coding standards. Admin tools, WooCommerce extensions, REST API integrations, SaaS connectors, and public WP.org plugins. Fully documented and delivered on an agreed date.
Custom plugins for every type of WordPress requirement
If the WordPress plugin repository does not have what you need, or the available plugins nearly do it but not quite, we build it from scratch. Every plugin is coded to WordPress standards, reviewed for security, and documented so your team can maintain it.
Admin Tools
Custom admin panels, settings pages, dashboard widgets, and bulk action tools that extend the WordPress admin interface for your workflow.
WooCommerce Extensions
Custom product types, checkout fields, payment gateway integrations, shipping calculators, order management tools, and WooCommerce hooks that go beyond what extensions offer.
REST API Integrations
Plugins that connect WordPress to external APIs: CRMs, ERPs, marketing platforms, payment gateways, logistics APIs, and SaaS tools your business already uses.
Membership and User Systems
Custom membership systems, user dashboards, role-based access control, subscription management, and content restriction logic built to your exact specification.
Public WP.org Plugins
Plugins built to WP.org submission standards with full readme.txt, screenshots, and compliance review. We manage the full submission and review process.
Documentation and Handover
Every plugin includes a full developer documentation file covering all hooks, filters, settings, and update procedures. Your team can maintain the plugin without us.
Our plugin development process
Specification and Scoping
We work with you to define exactly what the plugin needs to do, what systems it connects to, and what the admin interface should look like. This becomes the fixed scope.
Fixed-Price Quote
Based on the specification, we provide a fixed price in your currency and an agreed delivery date. No hourly billing, no scope creep surprises.
Build and Review
We build the plugin in a development environment, run internal code review and security checks, and test across WordPress versions.
Client Testing
We deploy to your staging environment for your team to test and provide feedback. We make revisions based on your feedback within the agreed scope.
Delivery and Documentation
The plugin is deployed to your live site with full documentation, all source files, and 30 days of post-delivery support.
Why businesses choose CrestVox for custom plugin development
No boilerplate generators
Every line of code is written from scratch. We do not use plugin boilerplate generators or copy-paste stacks. The code is clean, readable, and maintainable.
Security reviewed
Every plugin is reviewed for WordPress security best practices: nonce verification, capability checks, data sanitisation and escaping, and prepared SQL queries.
Full documentation
Every plugin comes with developer documentation covering all hooks, filters, options, database schema, and update procedures. Your team can work with it independently.
Fixed price and agreed date
We scope the plugin before any code is written. You know the price and delivery date before work starts. No hourly billing, no scope creep invoices.
International clients welcome
We build plugins for clients in USA, UK, AU, CA, and India. Billing in your currency, communication via email and WhatsApp, timezone overlap for live calls.
You own the code
Full code ownership transfers to you on final payment. We do not retain any rights or licences. You can modify, distribute, or sell the plugin as you see fit.
Frequently asked questions about custom WordPress plugin development
A single-feature plugin starts from $600 / Rs 50,000. A multi-feature business plugin typically costs $2,000 to $4,000 / Rs 1.5 to 3 lakh. Enterprise plugin suites with public APIs and SaaS integrations are quoted individually. Every plugin is scoped and fixed-priced before any code is written.
Yes. We build plugins to WP.org submission standards and manage the full submission process. This includes writing the readme.txt, creating screenshot assets, and handling the review team's feedback. WP.org plugin review typically takes 2 to 4 weeks after submission.
A single-feature plugin typically takes 1 to 2 weeks. A multi-feature plugin takes 3 to 4 weeks including testing and documentation. Enterprise suites are scoped individually. We agree the delivery date before any code is written and we hit it.
We code all plugins to current WordPress coding standards and avoid deprecated functions. Every plugin is tested against the current and previous two WordPress versions before delivery. For clients on maintenance plans, we include plugin compatibility checks on every major WordPress release.
Modifying a third-party plugin means your changes are overwritten every time that plugin updates. We build plugins that hook into WordPress and WooCommerce properly, so they work alongside other plugins without direct modification. If you need changes to an existing plugin, we build a companion plugin that extends it cleanly.
