About the service
Functionality built around your process
Some requirements no ready-made plugin covers: a price switch between business and retail customers with a Swiss company-ID check, a request-only product flow, a spare-parts finder or a cost calculator. We build these as custom WordPress plugins from scratch — with an admin screen your team can manage.

Discovery
Your workflow, step by step

The idea
Software should fit the process, not the other way round
Many teams bend their work around a plugin that almost fits: an extra spreadsheet here, a manual step there.
A custom plugin turns that around. It does exactly what your process needs, no more and no less — and the workarounds disappear.
Business value
Code that replaces workarounds
Manual steps, extra spreadsheets and plugin stacks that almost work cost time every day and fail at the worst moment. A custom plugin does the job in one place, follows your rules and can be extended when your business changes.
When a custom plugin is needed
- No plugin on the market does what you need
- Several plugins are stacked to imitate one feature
- Your team works around the website by hand
- A key feature lives in fragile theme code
What you will get
- A written specification for your approval
- A standalone plugin under version control
- An admin screen for settings and rules
- Documentation for your team and future developers
Benefits
Why custom plugins with Scaleable
We write plugins for our own projects too — from shop logic to block libraries — so yours comes from people who know where WordPress code tends to break.
-
Proven building blocks
Price switching, shipping rules, product finders and calculators are problems we have solved before, so we start from experience.
-
Structured data built in
Where a plugin outputs content, it can also output schema.org data, so search engines and AI assistants read it correctly.
-
Secure by design
Validated input, permission checks and safely escaped output are standard in every plugin, not an add-on.
-
Ready for every language
Texts are translatable and work with Polylang, so the plugin speaks every language your website does.
Principles
Custom Plugin Principles That Drive Results
-
Spec Before Code
We write down what the plugin does, for whom and in which cases before development starts. Surprises are cheaper on paper than in code.
-
Edge Cases Are the Job
Empty fields, unusual orders, wrong input: the rare cases decide whether a plugin can be trusted, so we plan them from the start.
-
Readable for the Next Developer
Clear names, comments and a changelog mean any developer — ours or yours — can pick up the code later.
Release isn’t the finish line
We don’t ship and disappear. We maintain what we build.
WordPress, WooCommerce and PHP keep moving. The developers who wrote your plugin also test it against new versions, fix what changes and add features as your process grows.
Part one
Plugin
A custom plugin built to your specification, tested and documented for your team.
- Specification and architecture agreed up front
- Code in Git with a clear version history
- Admin settings and a short user guide
Part two
Maintenance
The same plugin kept compatible with the WordPress, WooCommerce and PHP updates you install.
- Compatibility tests on staging before major updates
- Bug fixes from the people who wrote the code
- New features added as your process changes
Process
Our Plugin Workflow
A plugin starts with your process, not with code. We learn how the work is done today, agree on a written specification and only then plan the architecture — so the build stays focused and the release comes with tests and documentation.
-
Discovery
How the task is done today and where it hurts.
-
Specification
Features, roles and edge cases written down and approved.
-
Architecture
Data structure, hooks and settings planned before coding.
-
Build
Plugin developed in Git, step by step on staging.
-
Tests & Review
Real scenarios tested, code reviewed before release.
-
Release & Docs
The plugin goes live with a changelog and user guide.
Collaboration
You know the process, we write the code
You don’t need to speak PHP to work with us. We describe every feature in plain language, show working versions on staging early and let your team click through them. Feedback goes into the next round before anything reaches your live site.
- Specs in plain language
- Working versions on staging
- Your team tests before release
