What we build

Built around your theme, plugins, hosting and data.

WooCommerce settings in the WordPress admin for Maison Verde, on a custom Delivery slots tab: three time slots, bouquets per slot, a same-day order cut-off, a connected courier service and the role allowed to edit slots

Everything in one plugin

Your rules, settings and permissions in one place, not snippets scattered across the theme.

  • Custom fields, imports and approval steps
  • Checkout changes tested with payments and shipping
  • Outside services that fail safely, with a clear notice
Plugin code that checks the user's permission and a security token, cleans and validates a submitted cut-off time, saves it with update_option and registers the handler on an admin_post hook

Safe through every update

We extend WordPress the documented way, so core and plugin updates don’t undo your changes.

  • No edits to WordPress core or other plugins
  • Permission checks and clean data on every form
  • Source code and setup notes for the next developer

Request to release

Every change starts with an agreed checklist.

Change request CR-118 for Maison Verde, a same-day cut-off per delivery zone: the single 12:00 cut-off becomes 14:00 for the centre and 11:00 for the outskirts, tested with customer and shop manager roles, the cart, checkout and account pages, courier sync and card payments, with a rollback to plugin 1.2.1 and a full backup, stamped approved by Maison Verde on 3 October

  1. Review the site

    We read the existing code, plugins and hosting limits before anything is changed.

  2. Build the change

    Built as its own plugin or module, following the conventions your site already uses.

  3. Test on staging

    A copy of the site is checked with each user role, its content, connected services and failure cases. No real payments or messages go out.

  4. Release with a fallback

    We release at an agreed time, clear caches and re-check every flow the change touched.

WordPress development questions

Regression checks for Maison Verde's delivery-slots plugin: five documented checks pass on the live site, a PHP 8.5 update on staging shows one deprecation notice, and the next WordPress release is not tested yet
Can you fix someone else's plugin?
We review the code and reproduce the issue first. The fix depends on access, licensing, compatibility, and whether the change belongs in the original plugin instead.
Should we replace a plugin?
Only for a clear reason. A settings change, a small extension or a targeted fix may solve the problem without replacing what already works.
Will updates still need testing?
Yes. WordPress, PHP, theme and plugin releases can change behavior, so we document the code's dependencies and the checks to repeat, rather than promise lasting compatibility.
Can our team maintain the code?
You receive the source and documentation agreed in the scope. Third-party libraries it uses keep their own licenses and update requirements.
