WordPress plugin development

Custom WordPress plugins for Finnish businesses.

Do you need functionality on your WordPress site that no off-the-shelf plugin provides? Or has the current plugin jungle gotten out of hand?

I develop custom WordPress plugins that do exactly what you need — no more, no less. Lightweight, fast, and secure.

Why a custom plugin?

Off-the-shelf plugins solve common problems. Your business isn’t common.

There are over 60,000 plugins in the WordPress directory, yet many businesses still end up installing five plugins to solve a single problem. Every extra plugin slows your site, increases security risks, and makes maintenance a nightmare.

A custom plugin fixes that:

  • One plugin — one job. No extra code, no features you don’t use
  • Fast and lightweight. Minimal code means minimal impact on load times
  • Secure. No third‑party dependencies whose updates could break your site
  • Yours. The code belongs to you — you’re not locked into a single provider

What plugins can I build?

Practically anything you can do in a WordPress environment.

Business logic and automations

Plugins that automate recurring processes: form handling, email notifications, order management, customer portals, billing integrations and CRM connections.

Gutenberg blocks and content management

Custom Gutenberg blocks that give content creators the exact tools they need. For example pricing tables, service cards, case-study galleries, or industry-specific content structures.

API integrations

I connect your WordPress site to external services: payment providers (Stripe, Paytrail), booking systems, inventory management, accounting software, Google services and social media platforms.

Analytics and reporting tools

Dashboard views and reporting tools directly in the WordPress admin. Ad data visualization, conversion tracking, lead management and performance metrics all in one place.

WooCommerce extensions

Custom WooCommerce extensions: special pricing, product configurators, shipping logic, subscription automations and tailored checkout pages.

Off-the-shelf plugins vs. a custom extension

Why a custom extension is a better solution than five overlapping plugins?
Miten muut tekeeTapio Kauranen
Install 5–10 plugins to solve a single issue. Each one loads its own scripts and styles. A single custom plugin handles everything. Minimal code, maximum performance.
Plugin updates can break your site. Compatibility issues are common. A custom plugin is built specifically for your site. No unexpected compatibility problems.
Support for off-the-shelf plugins can end or a plugin can be abandoned. You’re at the mercy of the developer. The code is yours. Maintenance and further development are always possible.
Monthly fees add up: €10/mo + €15/mo + €20/mo = €540/year in license fees alone. A one-time investment that pays for itself quickly. No monthly fees.

How plugin development works

A clear process from idea to finished plugin.

1. Discovery and planning

We start with a short meeting to go over what the plugin needs to do. I’ll prepare a written technical plan outlining features, timeline, and budget.

2. Development

I’ll build the plugin following WordPress best practices: secure code, clear structure, and WordPress Coding Standards. You’ll get interim demos as development progresses.

3. Testing and installation

The plugin is thoroughly tested before installation. I’ll check compatibility with your theme and other plugins. I’ll install the plugin on your site and make sure everything works.

4. Documentation and handover

You’ll receive clear instructions for using the plugin. The code is fully commented to support future development. The plugin is yours — you can continue developing it yourself or hire me for updates.

Kansler Cookie Consent

An example of my work: my own plugin in the WordPress directory.

Kansler Cookie Consent is a completely free, lightweight, and professional cookie management plugin that I built and published in the official WordPress plugin directory.

The plugin includes, among other things:

  • Google Consent Mode v2 integration
  • Automatic blocking of scripts and iframe embeds
  • A built-in cookie scanner
  • Consent logs and a statistics dashboard
  • Full WPML and Polylang multilingual support
  • AI-assisted cookie descriptions and privacy page generation

This shows the level of WordPress plugins I build — and what I can build for you.

Price of WordPress plugin development

The price depends on the scope. Typically €500–€5000.

Small plugins — for example a simple form integration or a custom shortcode — can be completed in a few days. Larger projects like dashboard tools, API integrations or WooCommerce extensions take more time.

The price always includes

  • Technical planning and specifications
  • Development following WordPress Coding Standards
  • Testing and installation on your site
  • Documentation and user instructions
  • 30 days of support after delivery

Ongoing maintenance

  • Plugin updates alongside WordPress core updates
  • Development of new features as needed
  • Support and bug fixes

Maintenance is agreed separately and is typically 1–2 hours per month.
