Looks like you're in . Want the local site?
WordPress sites built around SaaS integrations, membership systems, and complex WooCommerce logic frequently hit a point where no available plugin covers the actual workflow. A custom plugin built to spec handles the integration correctly, does not break on third-party update cycles, and gives you full ownership of the code.
Your store has pricing rules that depend on customer tier, order history, geographic zone, or a combination of factors that available WooCommerce extensions cannot handle cleanly. The workarounds you have in place work until they do not, and the failure mode is usually the checkout. A purpose-built WooCommerce plugin encodes the logic once, correctly.
The site accumulated plugins over several years. Now it has 40 or more active, load times are slow, the admin is sluggish, and there are JavaScript conflicts on the front-end that nobody has been able to trace conclusively. Consolidating overlapping functionality into a single custom plugin reduces the plugin count and the surface area for conflicts.
Your Salesforce or HubSpot integration requirements go beyond what the available plugins offer, or your Stripe implementation involves subscription logic, metered billing, or customer portal functionality that the standard plugins do not cover. A custom integration plugin is built directly against the API, to the authentication method and data flow your platform requires.
Two plugins hook into the same WordPress filter. One loads a conflicting version of a shared library. A caching plugin and a WooCommerce extension produce inconsistent output for logged-in users. These conflicts are difficult to diagnose and expensive to fix when nobody owns the codebase of either plugin.
A membership plugin stores user access records in its own proprietary table. A form plugin keeps submissions in a format that does not map cleanly to Salesforce fields. When you need to migrate to a new platform or produce a compliance export, the data is effectively locked in a structure you did not choose and cannot easily modify.
Your LMS needs to gate content based on Stripe subscription status, push completion events to HubSpot, and surface a custom progress dashboard to the logged-in user. No single plugin handles all of that. A custom plugin does.
You have added filters or a companion plugin to change how an existing plugin behaves. The plugin developer pushes an update. Your customisation breaks. In an environment with Salesforce, HubSpot, or Stripe integrations, the blast radius when this happens is larger than on a simpler site.
Before any code is written, we document the plugin's full scope: functionality, data model, admin interface, external integrations, and edge cases. You approve the specification before development begins. It is the single source of truth for the build.
Code is written to the standards maintained by the WordPress core team, including naming conventions, file structure, data sanitisation, and security practices that any competent developer can read, audit, and extend.
Where the plugin requires configuration or data management, we build a custom admin screen inside the WordPress dashboard, designed for the people who will actually use it.
Salesforce, HubSpot, Stripe, and any other external service are integrated directly into the plugin, with proper OAuth or API key authentication, rate limit handling, error logging, and retry logic.
Core plugin functions are tested before handover. Integration flows, including webhook handling and API callbacks, are included in the test coverage. You receive a test report with the code.
You receive the full source code, a developer handover document covering architecture and extension points, and a user guide for non-technical administrators.
We document the plugin's full scope in a written specification covering functionality, data model, admin interface, API integration details, and edge cases. For SaaS integrations, this includes confirming API version, authentication method, and rate limit constraints. You approve the document before development begins.
Development runs on a staging environment you can access throughout the build. Integration work is done against sandbox or test environments for Salesforce, HubSpot, and Stripe. Scope changes go through a documented change request, not silent scope creep.
Unit tests cover core functions. Integration tests cover API flows, webhook handling, and subscription state transitions. You perform user acceptance testing on the staging site. Issues are resolved before production deployment.
The plugin is deployed to your production site. You receive the source code, documentation, and a handover session covering the plugin's architecture and how to extend it. The plugin is yours from that point forward.
Yes. Both Salesforce and HubSpot provide well-documented REST APIs that support custom WordPress plugin integrations. We build the integration to the specific field mapping, trigger events, and sync schedule your team requires, rather than the lowest-common-denominator approach most available plugins take. The integration is tested against your sandbox environment before production deployment.
Most custom plugins take three to six weeks from approved specification to production deployment. A single-purpose integration plugin takes less time. A plugin replacing a full membership and LMS stack with Stripe billing integration takes longer. The timeline is confirmed in the specification phase and does not change without a documented scope change.
Available Stripe plugins cover standard WooCommerce checkout flows. They do not cover metered billing, usage-based subscription tiers, customer portal access control tied to WordPress role, or complex proration logic. If your billing model requires any of those, a custom Stripe integration plugin built directly against the Stripe API is the correct tool.
Data migration is scoped in the specification phase. We map the existing data structure, including subscription records and access entitlements, to the new format, run the migration on a staging copy of your database, verify every record, and then run it on production. The old plugin stays active until the migration is confirmed clean and the new plugin is tested against live data.
No. The handover includes full source code and documentation sufficient for any competent WordPress developer to maintain and extend the plugin. We offer ongoing support and maintenance arrangements for clients who prefer them, but there is no lock-in and no ongoing dependency.
If an existing plugin is failing to cover your SaaS integration, your membership logic, or your WooCommerce pricing rules, a custom plugin is usually the cleaner fix than another layer of workarounds. Send us a description of the functionality you need, the APIs or platforms involved, and where the current setup is falling short. We will review it and come back with a scope outline and a timeline.
