Custom WordPress Plugin Development for Teams Who've Outgrown Off-the-Shelf

Off-the-shelf plugins are built for the average case, and your business usually isn't the average case. Wiselogix Technologies builds custom WordPress plugins scoped to exactly what you need — nothing bundled that you'll never use, and nothing missing that forces you to bolt on a second plugin.

Every plugin we deliver is documented, follows WordPress coding standards and is built to stay compatible as WordPress and PHP evolve.

Common plugin projects

• CRM and ERP integrations — syncing leads, customers or orders between WordPress and the systems your team already uses.
• Booking and scheduling — custom booking flows built around your services, availability rules and confirmation steps.
• Custom checkout logic — pricing rules, fees, validation and fulfillment steps that standard WooCommerce settings can't express.
• Content and admin tools — custom post types, field groups and admin screens that make managing structured content straightforward.

Build, extend or customize?

A new plugin isn't always the answer. If an existing plugin already covers most of what you need, extending it is usually faster and more economical than a rebuild. If nothing fits, we build from scratch. We'll give you an honest recommendation before any work is quoted.

Built to WordPress standards

We follow the WordPress coding standards, document every plugin and test against upcoming WordPress releases, so updates to core are far less likely to catch you by surprise. You receive the full source code, and it is yours.

How a plugin build works

1. Discovery and specification. Requirements, edge cases and the data model, captured in a functional specification both sides sign off on before code is written.
2. Core development. Custom post types, fields and the core plugin logic, built and tested in a local WordPress environment.
3. Integration and staging. Connections to third-party APIs or CRMs, deployed to a staging site for your review.
4. Quality assurance and handover. Testing across browsers and themes, documentation, and a walkthrough video so your team can maintain the plugin.
