Custom WordPress and WooCommerce plugins
When an off-the-shelf plugin does not do exactly what you need, we write the solution from scratch. A custom plugin does only what is required, without the extra code that slows a site down.
In short
A custom WordPress plugin is a dedicated PHP module that extends WordPress or WooCommerce with a function matched to a company’s process. Canpol Bis writes them to WordPress Coding Standards, with security measures, tests and documentation.
What the service includes
Customer portals
A customer area with orders, documents, statuses and requests.
Bookings and appointments
Sign-up systems, calendars and email or SMS confirmations.
B2B modules
Contractor price lists, wholesale orders, file import and internal approvals.
API integrations
Connecting the site to external services: payments, couriers, CRM and company systems.
Admin panel
Clear settings in the WordPress dashboard so you can manage the plugin without a developer.
Technical approach
Architecture
Classes and namespaces, use of hooks (actions/filters), the Settings API and custom REST API endpoints, without touching the core.
Data
Custom post types or custom tables created with dbDelta, with version migrations and data cleanup on uninstall.
Security
Capability checks, nonces, input sanitisation and output escaping, prepared queries via $wpdb->prepare.
Code quality
WordPress Coding Standards (PHPCS), static analysis (PHPStan), unit and integration tests, semantic versioning and a Git repository.
Performance
Assets loaded only where needed, result caching (transients/object cache), efficient queries and background tasks.

Translation-ready code and user and deployment documentation for your team.

FAQ
Frequently asked questions
How is a custom plugin different from an off-the-shelf one?
Off-the-shelf plugins are generic and often include features you do not need. A custom plugin is matched to your process and is usually lighter.
Will the code and plugin belong to me?
The scope of rights is set out in the contract and quote. As standard you receive the working plugin together with operating documentation.
What about WordPress and WooCommerce updates?
We write plugins to WordPress standards. After updates we can check compatibility and apply fixes for you.
How does pricing work?
After a conversation we write down the requirements and present the scope, schedule and cost. Larger projects are split into stages.
How do you keep plugins secure?
We use capability checks, nonce tokens, input sanitisation, output escaping and prepared queries. Code goes through static analysis and review before release.
Can a plugin communicate with an external system?
Yes. A plugin can call external APIs, receive webhooks through its own REST endpoints and process data in the background on a schedule.
