Custom WordPress Plugin Development
When no plugin does what you need.
Who this is for: Site owners who have hit the limit of off-the-shelf plugins — you need a specific integration, workflow, or feature that doesn’t exist yet, or an existing custom plugin that needs to be fixed or extended. Billed at $89/hour, tracked to the minute, with a fixed estimate before we start.

- Expert advice for future plugin updates and scalability
Ensuring your WordPress site remains stable, secure, and up-to-date
- Regular WordPress and plugin updates (1-2 times monthly, critical security updates immediately). Our maintenance covers version updates to the 2nd and 3rd digits. "Major" updates (1st digit) require separate quotes due to API changes, based on website size.
- All updates are first carried out by us in a test system to avoid problems/failures of the live system during updates.
- IMPORTANT: No new plugins will be installed or changes made to the system without prior notification to the client; only existing software components will be updated to keep technically up to date.
- Setup of an automated backup that is kept on an external system for at least 14 days.
- Requirements: Your WordPress must use "update-safe" development with a child theme (if not, we can prepare your site for maintenance – separate quote available).
- Note: For WordPress installations based on WooCommerce (online shops), we have a price-adjusted maintenance package.
- Major theme/WordPress upgrades not included due to variable workload. We'll provide cost estimates when needed, including for unsupported plugins/themes requiring replacement.
- Note: If you also have a web hosting package with us, we will grant you an additional discount of 10% on the WordPress maintenance package.

FAQ
WORDPRESS CUSTOM PLUGINS
Outdated plugins are the #1 cause of WordPress hacks. Here you’ll find everything about our update process, our staging-first approach, and what “no surprises” maintenance looks like in practice.
A custom WordPress plugin is purpose-built code that adds specific functionality to your website — functionality that no existing off-the-shelf plugin provides, or that existing plugins handle poorly for your use case. You need a custom plugin when your business logic is unique: a specific calculation tool, a custom booking flow, a proprietary data integration, an automated workflow, or a specialized user interface element. Rather than forcing your business to fit a generic plugin, a custom plugin is built to fit your business exactly.
We develop virtually any WordPress-native functionality, including: custom post types and taxonomies, advanced custom fields and data structures, API integrations with third-party services (CRMs, ERPs, payment providers, shipping APIs), custom search and filtering logic, automated notification or reporting systems, role-based access control, custom admin interfaces, and complex form processing with conditional logic. If it can run in WordPress, we can build it.
Development is billed at $89/hour, tracked to the minute. Before starting, we conduct a technical scoping session to understand your requirements, define the feature set, and provide a realistic time estimate. For larger projects, we can structure the work in defined milestones with intermediate deliverables and cost checkpoints.
Compatibility is a core part of our development process — not an afterthought. Before and during development, we conduct compatibility checks against your existing theme and plugin stack. We follow WordPress coding standards and best practices (hooks, filters, proper enqueueing of scripts/styles) to ensure the custom plugin integrates cleanly without interfering with existing functionality.
Plugin configuration means adjusting settings within what a third-party plugin already offers. Custom development means writing new code that extends or replaces that functionality entirely. We always assess whether an existing solution can meet your requirements first — only recommending custom development when it genuinely delivers better results, lower long-term costs, or capabilities that simply don't exist in the plugin marketplace.
Yes. We build custom plugins following WordPress development standards, with clean, documented code and proper use of WordPress hooks — meaning updates to WordPress core or other plugins are far less likely to break your custom functionality. We also provide expert guidance on scalability: how the plugin can be extended or adapted as your business requirements evolve, without requiring a complete rebuild.
Yes. We take over existing custom plugins for bug fixes, performance improvements, or feature additions — regardless of who originally wrote the code. We begin with a code review to understand the existing architecture before making any changes, ensuring our modifications are coherent with the original structure and don't introduce new issues.
Performance optimization is included in every custom plugin project. This means efficient database queries (avoiding N+1 query problems), proper use of WordPress transients and caching APIs, minimal asset loading (only on pages where the plugin is active), and clean deactivation/uninstallation routines. A poorly performing plugin can negate any business benefit it provides — we build with performance as a requirement, not a bonus.
After delivery, the plugin becomes part of your WordPress environment and should be maintained like any other component. We document the plugin's functionality and handover fully. For ongoing updates, compatibility checks after WordPress version upgrades, or feature additions, the hourly rate applies — or you can use the Support Package for smaller, recurring tasks.
Yes. API integrations are one of the most common custom plugin use cases. Whether you need real-time data sync with a CRM (e.g., HubSpot, Salesforce), automated order forwarding to an ERP, or a custom connection to a logistics or inventory system, we design and build the integration layer as a proper WordPress plugin — secure, maintainable, and aligned with your existing data architecture.
FAQ
MAINTENANCE PACKAGE
Custom plugins need care too — updates, PHP compatibility, and fixes when WordPress core changes. Here’s what our maintenance package covers.
The Maintenance Package covers updates to WordPress core and all standard installed plugins. Custom plugins developed by us do not receive automatic updates in the same way (they don't update via the WordPress repository) — however, the maintenance routine includes compatibility monitoring: if a WordPress core or plugin update affects your custom plugin's behavior, we identify this in the staging environment before it reaches your live site, and flag it for resolution.
This is caught in the staging environment as part of the maintenance routine. Rather than your live site breaking unexpectedly, you receive advance notification that the custom plugin requires adjustment, along with a scoped estimate for the fix. This structured approach is precisely the value of combining custom development with ongoing maintenance coverage.
FAQ
SUPPORT PACKAGE
Two technician hours, priority access, and a direct line to our team — but is it worth it for your site? These FAQs help you decide if a monthly support retainer makes sense for your situation.
Yes — and this is an efficient way to handle iterative improvements. Small feature additions, UI adjustments, new field additions, or logic changes to an existing custom plugin are well-suited to the Support Package's hourly structure. Rather than initiating a formal development project for minor changes, Support Package clients can request these incrementally with priority handling and transparent minute-by-minute tracking.
Phone support is covered under the Support Package at preferential rates ($69/h). If your team needs guidance on using a custom plugin's admin interface, understanding its outputs, or planning future extensions, additional hours can be booked through the Support Package at the reduced Support Package rate.
