Custom WordPress plugins

Purpose-built WordPress plugins for when marketplace tools force awkward workarounds. Booking calendars, memberships, subscriptions, donations, delivery, translation, and database forms, written around how your team actually works.

When a custom plugin makes sense

A good rule: if you have tried two or three marketplace plugins and staff are still copying data into spreadsheets, sending manual reminders, or fixing double bookings by hand, the problem is the fit, not the configuration. A custom plugin does the one job your business needs and nothing else, so there are fewer settings to break and fewer updates to worry about.

The reverse is also true. If a well-maintained plugin covers 90% of the need, it is usually better to configure it and extend the last 10% than to rebuild it. That call is made during discovery, with reasons.

Plugin types already built

The portfolio includes 18 custom WordPress plugins. Some examples:

• Booking: service-bay scheduling with capacity caps for an auto-care workshop, holiday-villa reservations that prevent double booking and take deposits, homestay availability calendars, catering reservations, and mengaji class booking
• Membership and directories: alumni registration with record checks and renewals, and a searchable member directory for an association
• Subscription and donation: recurring subscriptions with Stripe and FPX, and subscribe-and-donate flows with receipts
• Data feeds: a plugin that pulls market prices from the London Stock Exchange API on a schedule and caches them to stay within server limits
• Delivery: delivery slots, courier assignment, and order status tracking
• Translation: language switching and translated pages for organisations publishing in more than one language
• Database forms: validated multi-field forms that store enquiries in the database with an admin review screen

How the plugins are written

• Standard WordPress hooks, capabilities, and nonces, so the plugin behaves like the rest of the admin
• Admin screens designed around the staff who use them, not around the database tables
• Input validation and escaping on every form, and least-privilege access for each user role
• Scheduled tasks (WP-Cron or server cron) for reminders, expiries, and data syncs
• Compatibility with WooCommerce where payments or orders are involved
• Code kept in your own repository, so it can be maintained or extended later

Working with an existing site

Most plugins are added to sites that already exist. The plugin is developed and tested on a staging copy of your site first, then installed on the live site once you have checked it with real scenarios. If the site was built by another developer, that is fine; the plugin does not depend on who built the theme.

How a project runs

1. Discovery. Goals, users, constraints, and the workflows that must work on day one. Send what you have on WhatsApp or the quote form; a short call follows if the scope needs it.
2. Scope and quote. A written, custom quotation with assumptions and exclusions listed. No fixed packages, so you are not paying for pages or features you do not need.
3. Build and launch. Work happens on a staging copy you can review before anything goes live. Launch includes redirects, analytics, and a final check of forms and payments.
4. Support. Handover of every account and credential, plus maintenance, security checks, and backups if you want them after launch.

What you own at the end

The domain, hosting, admin accounts, and code are registered to your business, not to the developer. You get the logins on handover, so another developer can pick the project up later if they need to.
