The WordPress plugin that fits your exact problem.

For site owners where the standard repository stops fitting. Bespoke plugins for WordPress & WooCommerce: clean PHP, tested, documented — and handed over so any developer can carry it forward. Custom plugins from 4.500 €.

01 · Custom over plugin sprawl

One plugin of your own beats ten from elsewhere.

Too many WordPress problems get patched over with ever more third-party plugins — until performance, security and maintainability suffer. We build the one extension that actually solves your problem instead: lean, no bloat, no hidden dependencies.

  • Custom plugins tailored exactly to your process
  • WooCommerce extensions: checkout, shipping, pricing, inventory
  • Gutenberg blocks & custom block patterns
  • REST API endpoints and third-party integrations
  • No lock-in: code, repository and docs are yours

03 · Custom vs. off-the-shelf

Custom plugin or a ready-made one from the shop?

Not every problem needs custom development. For recurring requirements we have ready-made plugins with an annual licence in the shop — instantly usable and cheaper. For anything genuinely specific, we build custom. In the first call we'll tell you honestly which fits you.

  • Ready-made plugin: instantly available, annual licence, maintained
  • Custom plugin: exactly your process, your code, no licence fee
  • Maintenance optional as an ongoing contract

04 · How we build

Code anyone can take over from us.

01

Spec & audit

We clarify the exact scope, review the existing setup and estimate effort and risks honestly.

02

Build on staging

Development with code reviews and tests for critical paths. Visible progress daily instead of a months-long black box.

03

Hardening

Input validated, capabilities and nonces checked, update and uninstall paths clean.

04

Handover

Repository, docs and access go to you. We can take on ongoing maintenance if you want.

FAQ

Common questions about plugin development.

01What does it cost to have a WordPress plugin developed?

There's no flat answer — the price depends on scope, integrations and data volumes. That's why we work audit-first: in an audit sprint we scope the exact effort and you get a binding fixed-price offer before any development starts. No open-ended hourly account.

02When is a custom plugin worth it over a ready-made one?

A custom plugin is worth it when your requirement is genuinely specific, or when several ready-made plugins would otherwise be stacked. For standard requirements we deliberately recommend a ready-made plugin from the shop — we'll tell you honestly in the first call which is cheaper.

03How long does it take to develop a custom WordPress plugin?

A clearly scoped plugin is usually built in a fixed-price sprint with a fixed date. We define the exact scope up front; during the build you see daily progress on a staging system.

04Can you connect a WooCommerce plugin to our interface or ERP?

Yes, that's one of our focus areas: custom WooCommerce extensions integrating ERP, CRM, warehouse, payment or shipping — cleanly via REST APIs and webhooks rather than around the core.

05Do custom plugins stay update-safe with WordPress and WooCommerce updates?

Yes. We develop against the official WordPress and WooCommerce hooks and APIs following the WordPress Coding Standards. So the plugins survive future core updates.

06Do you maintain the plugin after development?

On request, yes — via a maintenance contract with updates, security checks and compatibility care. Alternatively we hand the plugin over cleanly to your team.

07Is a custom-built WordPress plugin GDPR-compliant?

Data protection is part of development: validated input, data minimisation and secure processing. We implement GDPR requirements per use case and advise on data-processing agreements where third-party systems are involved.

08Do we own the code of the finished plugin?

Yes, entirely. The repository, source code and documentation are yours — no lock-in. Any other WordPress developer could take the plugin over.

09Can you extend an existing plugin instead of building a new one?

Yes. We read into existing code, document the state and develop further on that basis — even when the prior documentation is thin.

10Can the plugin be published in the official WordPress repository?

On request we prepare the plugin to the WordPress Coding Standards for publication in the official plugin directory and guide it through the review. For internal plugins this isn't necessary.

Straight talk

What might still hold you back.

01You're a single founder — what if you're unavailable?

That's exactly why every project is built to be handed over: a standard stack instead of exotic tools, clean and tested code, documented architecture and deployment — and the repository is yours. Any competent developer can carry on without me. You're never chained to one person.

02Will the budget run away from me?

No. The project is cut into milestones with a fixed scope and a fixed price. You pay per milestone, get a working result after each one, and decide whether to continue. No open-ended hourly tab, no surprise on the invoice.

03Can one person deliver as fast as an agency?

Often faster. No coordination overhead, no ticket ping-pong, no friction between junior and senior — you talk directly to the person who builds. If scope grows, I bring in vetted partners selectively, always transparently agreed.

04What if I later want to continue in-house or with another provider?

Then you take the code, the docs and all access with you — it's yours anyway. I deliberately build in no dependency that locks you to me. Good work doesn't need a lock-in clause.

05Will we get help if something breaks later, even without a maintenance contract?

Yes. Every plugin is handed over documented, and newly developed code comes with a warranty. If you want ongoing care afterwards, there are Care plans from 59 €/month — but no obligation: you can also run the plugin entirely yourself or with another developer.
