Integrations and API Connections
APIsCRMIntegration
For websites that need clean technical connections to CRM, ERP, newsletter tools, booking systems, data sources or external services.
WordPress Plugin Development
WordPress Plugins
From Germany.
We develop custom WordPress plugins for businesses that need functions, integrations, data logic and workflows that off-the-shelf plugins cannot deliver — clean code, secure, performant and built to last.
Custom Plugin Development
When standard plugins reach their limits.
Many WordPress websites outgrow what standard plugins can offer. Specific requirements around functions, integrations, data logic or internal workflows can no longer be handled cleanly by off-the-shelf solutions — and every additional plugin increases complexity, performance risk and maintenance overhead.
Custom WordPress plugins solve precisely what the project actually needs. We develop extensions that integrate cleanly into the existing system, address requirements with accuracy and remain maintainable, secure and performant for years.
Typical Plugin Projects
What we build plugins for.
Custom plugins emerge where standard extensions reach their limits and specific requirements call for a purpose-built solution.
WooCommerce Extensions
WooCommerceShopCommerce
For shops that need custom product logic, pricing rules, checkout modifications, shipping logic or individual purchase workflows.
Data Processing and Automation
DataAutomationLogic
For workflows where data needs to be captured, processed, validated, evaluated or automatically passed to other systems.
Protected Areas and Roles
RolesAccessSecurity
For member areas, login systems, role-based access and internal tools that go beyond what standard plugins provide.
Editorial Tools
BackendEditorialFields
For teams that need custom content types, fields, workflows and management processes within the WordPress backend.
Frontend Extensions
FrontendInteractionUX
For interactive elements, calculators, filters, maps, forms or displays that cannot be achieved with standard tools.
Quality Standards
What matters in plugin development.
A custom plugin is a sound investment when architecture, security, performance and maintainability are considered from the start.
Services
From concept to maintenance.
We accompany plugin projects from the first requirement through to long-term care and further development.
01
Requirements and concept
We clarify goals, context, data flows, permissions, dependencies and technical constraints before development begins.
ConceptRequirementsPlanning
02
Plugin architecture and data model
Database structure, custom post types, taxonomies, fields, roles, APIs and admin interfaces are set up for long-term stability and clarity.

03
Development and integration
PHP, WordPress APIs, JavaScript, REST endpoints and external services are cleanly developed and integrated into the existing website.

Frontend and interaction
When the plugin needs visible elements, we design and develop interfaces, forms, outputs and interactive components with attention to usability and presentation.

Testing and quality assurance
Functional tests, compatibility checks, security audits and performance measurements ensure the plugin operates stably and securely.

Maintenance and further development
WordPress core updates, PHP versions, new requirements and extensions are looked after long term so the plugin stays reliable.

Why BxW
Why BxW for plugin development.
Custom plugin development takes more than PHP skills. We combine deep WordPress knowledge with an understanding of the project behind the technical requirement.
WordPress understood in depth
Hook system, database, APIs, Gutenberg, custom fields, roles and security mechanisms — mastered through years of experience with complex WordPress projects.
Understanding the project first
Before we write code, we understand the business model, audience, existing website, workflows and the question of what the plugin actually needs to solve.
Clean code, no unnecessary dependencies
Our plugins are self-contained, documented and developed so they create no unnecessary dependencies, conflicts or performance issues.
Design and development together
When a plugin needs visible interfaces, we design and develop frontend, admin interface and user guidance in a single process.
Long-term support
We remain available for updates, extensions, WordPress compatibility and new requirements that arise after the initial release.
In practice
Extensions in practice.
Custom WordPress plugins, system integrations and technical extensions for precise requirements.
Key questions
Before the plugin project.
When is a custom WordPress plugin worthwhile?
When standard plugins carry too many features, impact performance, create security risks or simply cannot address the requirements. A custom plugin does exactly what the project needs — cleanly, securely and without unnecessary dependencies.
What does a custom WordPress plugin cost?
That depends on requirements, complexity, integrations and frontend effort. Simple extensions start around €1,000, more complex plugins with data logic, APIs and admin interfaces typically run above €5,000. We clarify the scope before starting.
Can existing plugins be extended or replaced?
Yes. We review existing plugins for code quality, dependencies, security and performance and decide together whether extending, rebuilding or developing from scratch is the better path.
How is security ensured in plugin development?
Through input validation, nonce checks, capability verification, prepared database statements and reviewed code. Security is not something added afterwards — it belongs in every phase of development.
Will the plugin stay compatible with WordPress updates?
When the plugin is built cleanly on WordPress standards and official APIs, it remains compatible with regular updates. We provide ongoing compatibility checks and adjustments on request.
Does BxW develop WooCommerce plugins?
Yes. For WooCommerce we develop custom extensions for product logic, checkout modifications, pricing rules, shipping logic, coupons, integrations and everything that goes beyond standard WooCommerce plugins.
How long does plugin development take?
Simple plugins can be built within a few weeks. More complex projects with integrations, data models and admin interfaces typically take four to twelve weeks. We align the timeline before the project starts.
Who handles maintenance after development?
We look after plugins long term covering WordPress updates, PHP versions, security matters and new requirements. Alternatively, we hand over cleanly documented code that internal teams or other developers can continue with.
