When off-the-shelf plugins do too much, too little or slow your site down, or when WordPress has to talk to another system. Custom WordPress plugin development gives you one small plugin that does exactly that job, keeps changes out of your theme and survives updates. ![Custom WordPress plugin development: custom development by Sukesh Das](https://sukeshdas.com/wp-content/uploads/2026/10/sd-service-plugin-1024x853.webp) **02** What you get ## Everything the job *needs.* WooCommerce plugin development and custom WordPress features from a WordPress plugin developer who writes to WordPress standards and documents the work. - **Custom post types and fields** Structured content such as listings, events or case studies, easy to edit in the admin. - **WooCommerce extensions** Checkout rules, product options, pricing logic and order workflows. - **Payment gateways** Payment integrations built and tested, including gateways for regional providers. - **API connections** WordPress connected to CRMs, ERPs, shipping, email and other services. - **Admin tools** Settings screens, reports and bulk tools your team will actually use. - **Licensing and updates** License keys and automatic updates if you plan to sell the plugin. - **Documentation** Clear notes on how it works and how to change it. - **Code you own** Once paid, the code is yours to use, change and host anywhere. [Get a free quote](https://sukeshdas.com/contact-us/?service=plugin#brief)Fixed price in writing, usually within one working day. **03** Who it is for ## Built for people *like you.* Most of these clients are in the US, UK, Canada and Australia, and I have worked with clients in 70 countries. Not the right fit if an existing, well-kept plugin already does the job. I will tell you if one does. - ### Businesses with a process no plugin covers A small custom plugin that does exactly your job, instead of five plugins that almost do. - ### WooCommerce stores Custom checkout, pricing, shipping or payment rules built to survive updates. - ### Agencies and product teams Clean, documented code your developers can read, extend and ship. **04** Sound familiar? ## What usually goes *wrong.* 01 ### Five plugins for one job A stack of plugins held together with settings, and each update is a gamble. 02 ### Changes lost on update Custom edits were made inside a theme or someone else's plugin, and the next update wiped them out. 03 ### Systems that do not talk Orders, leads or bookings are copied by hand between WordPress and your other tools. **05** Under the hood ## How the code is *built.* The standards behind every plugin, which matter most when someone else has to maintain it later. 01 ### Hooks, not hacks Features attach through WordPress actions and filters, so nothing in core, your theme or other plugins is edited. 02 ### REST API endpoints Custom routes with permission checks for apps, integrations and admin screens that talk to WordPress. 03 ### Database design Post types and meta where they fit, and custom tables with proper indexes when the data is large or relational. 04 ### Roles and capabilities Every action checks who is allowed to do it, with custom capabilities when your team needs finer control. 05 ### Nonces, sanitizing and escaping Requests verified, input cleaned and validated, and output escaped, following the WordPress security guidelines. 06 ### Background jobs WP-Cron or Action Scheduler for imports, syncs and emails, so long tasks never slow down a page load. 07 ### Compatibility Tested on current WordPress and PHP versions, with WooCommerce HPOS, multisite and popular plugins where relevant. 08 ### Automated tests Tests for the critical paths, so future changes do not quietly break what already works. 09 ### Clean uninstall Settings and data removed on request when the plugin is deleted, with nothing left behind in the database. **06** How it works ## Four steps, no *surprises.* 1. 01 ### Tell me what you need Send a short brief or book a call. I reply within one working day with questions or next steps. 2. 02 ### Get a fixed quote You get the scope, the price and a dated plan in writing before any work starts. 3. 03 ### I do the work Built and tested on a staging copy, with an update after each milestone. 4. 04 ### Launch and handover It goes live at a quiet time, I check everything again, and you get a recorded walkthrough and notes. **07** Why work with me ## One senior developer, *start to finish.* You talk to the person doing the work, from the first call to launch day. The domain, hosting, content and code stay in your accounts, and the price is agreed before anything starts.

[Ask me directly](https://sukeshdas.com/contact-us/?service=plugin#brief) Who owns the code? You do. Once the project is paid, the code is yours to use, change and host wherever you like. Can you add a feature to a plugin I already use? Usually, yes. Where possible I build it as a small separate plugin, so your change survives the original plugin's updates. How is custom WordPress plugin development priced? After a short scoping call I send a fixed quote for a clearly defined first version. Larger products are split into milestones so you can review progress as we go. Do you build WooCommerce payment gateways? Yes. WooCommerce plugin development is a large part of my work, from payment gateways and checkout extensions to my own commercial WooCommerce payment plugins. Will the plugin keep working after WordPress updates? It is written to WordPress coding standards using WordPress's own APIs, which is what keeps plugins working through updates. Ongoing maintenance is available if you want it covered. How long does a custom plugin take? A focused plugin usually takes one to four weeks, depending on the features and integrations. Larger products are planned in milestones, each with a date. What do I need to provide? A description of what it should do, examples of the current workflow, API documentation for any outside service, and access to a staging copy of your site. Custom plugin or an existing plugin: which is better? If a well-maintained plugin already does the job, use it. A custom plugin makes sense when existing ones do too much, too little or slow the site down, or when you need a specific integration.
