Custom Development — Custom Plugins, Features, API Integrations
The custom WordPress engineering your business logic actually needs.
Custom plugin development, feature builds, API integrations, headless setups, Gutenberg blocks, WooCommerce extensions, admin UX, background workers and MCP tools — engineered by a team that ships WBP’s own plugins. Every line versioned, tested and shipped under CI, with a maintenance plan attached.
Custom Development, right inside your WordPress admin.
No new dashboards to learn. Every deliverable ships as native WordPress UI — the same screen your editors, admins and agencies open every day.
Post Editor — Custom Field Mapping — captured from a live WpBulkPublishing install.
Great fit if
- Founders whose business logic doesn’t fit an off-the-shelf plugin
- SaaS teams needing a WordPress front-end for a backend they own
- Agencies white-labelling engineering
- Publishers automating editorial workflows
Not for you if
- ‘Change the button colour’ (use Maintenance)
- Full custom themes without a design system (start with Design)

Frequently asked.
Do you code in modern PHP or the old procedural style?+
Modern. PSR-4, Composer, dependency injection where useful, tests on anything non-trivial. Legacy-style code is only used when a host demands it.
Can you work with our existing dev team?+
Yes — we regularly ship inside a client’s repo under their PR review process.
Do you own the code we pay for?+
You do. Full IP transfer on delivery, MIT or your licence of choice.
Do you handle multisite / headless?+
Yes. Multisite is common; headless (React / Next front-end, WP as CMS + REST/GraphQL) is quoted separately depending on the front-end scope.
What if requirements change mid-build?+
Weekly demos surface changes early. In-scope tweaks are absorbed; new user stories are quoted transparently before we touch them.
