WordPress Plugin Development – Exactly the Function Your Website Is Missing

We develop custom WordPress plugins for cases where ready-made extensions do too much, too little or the wrong thing. Programmed cleanly to WordPress standards, update-ready and documented.

Short & clear

WordPress plugin development produces a custom extension that takes over a clearly defined task on your website – such as a calculator, an interface to your inventory management system, custom content types or blocks for the editor. Nano Concepts programs such plugins to the WordPress Coding Standards with hooks, the REST API and proper permission checks, so they survive WordPress updates. Small plugins usually fall under the Starter package from €2,500, extensive extensions with integrations under the Professional package from €8,000; the exact quote follows after the initial consultation.

WordPress plugin development with Nano Concepts

WordPress plugin development pays off whenever a function on your website can't be solved cleanly with ready-made extensions. Typical examples are a price or funding calculator, passing form inquiries to your CRM, custom content types for job postings or properties, an interface to your inventory management system, or special blocks for your editorial team. Instead of combining three plugins that slow each other down, we create one WordPress plugin that handles exactly this task – lean, traceable and with documented source code.

01

We program to the WordPress Coding Standards and use the mechanisms WordPress provides for this: actions and filters, custom post types and taxonomies, the Settings API, REST API endpoints and blocks for the block editor. Security is part of it from the start – every input is validated and sanitized, forms are protected with nonces and actions are tied to user permissions. That way your plugin keeps working after WordPress and PHP updates and doesn't open a back door into your website.

02

Many companies come to us with a specific problem: a purchased plugin is no longer maintained, a page-builder add-on slows the site down or a workflow requires manual work every day. We analyze what you have, decide with you whether adapting or rebuilding makes more sense, and take over maintenance on request. If WooCommerce is in use, we also extend store functions such as pricing, shipping rules or exports. We manage the source code in Git, so every change stays traceable.

FAQ

Frequently asked questions about WordPress plugin development

Yes, and it pays off above all when ready-made plugins only partly cover your workflow, several extensions would have to be combined or a vendor no longer maintains its plugin. We first check whether an existing solution with a small adjustment is enough. Only when a custom development is clearly better do we recommend it.

A manageable plugin, such as a calculator or custom content types, usually falls under the Starter package from €2,500. We price plugins with integrations to ERP or CRM, extensive settings or WooCommerce logic under the Professional package from €8,000, and large extensions individually as an Enterprise project. After the free initial consultation you receive a transparent quote, preferably at a fixed price when the scope is clear.

A clearly defined plugin is often finished in a few weeks; integrations with external systems take longer because of coordination and testing. We plan in stages with interim versions on a test environment, so you see early on whether the function fits.

If it is developed to WordPress standards, generally yes, because we use official interfaces instead of interfering with the WordPress core. Under a maintenance contract, we test major WordPress or PHP version changes in advance on a test environment.

Yes. We review the existing code for quality, security and compatibility and decide with you whether adapting or rebuilding makes more sense. We prefer to extend purchased plugins via their hooks, so vendor updates don't overwrite your customizations.

Yes. We develop custom blocks for the block editor with React and the official WordPress packages, so your team maintains content in the website's design. For WooCommerce, we extend things like pricing logic, shipping rules, product fields or exports.
