Custom vs Off-the-Shelf

Why a custom plugin often wins

A premade plugin is quicker to install. A custom one is cheaper over time when your process is unique.

Off-the-shelf plugin

  • Generic features you may never use
  • Extra code that slows your pages
  • Workarounds for your exact process
  • Update and support depend on a third party

Custom plugin by Online Creatives

  • Built around your workflow
  • Lean code that loads only what is needed
  • Integrates with M-Pesa, CRMs and your systems
  • You own the source and decide the roadmap

How We Build

Engineering that keeps your site safe

Every plugin follows the same standards, so it stays secure and maintainable as your business grows.

  • Security first: nonce checks, capability checks, sanitised input and prepared queries
  • Clean scope: namespaced CSS and JavaScript so Elementor and themes never clash
  • Safe updates: idempotent, version-gated database migrations that never lose data
  • Performance: assets load only on the pages that need them
  • Compatibility: PHP 7.4+, HPOS and caching-plugin aware

FAQ

Frequently asked questions

How much does custom WordPress plugin development cost in Kenya?

Cost depends on scope: a small admin feature is a fraction of a payment gateway or booking system with a customer portal. We give a fixed-price quote in KSh after a short discovery call, with milestones so you always know what you are paying for.

Why choose a custom WordPress plugin instead of an off-the-shelf one?

An off-the-shelf plugin is built for the average user, so you pay for features you never use and still miss the one you need. A custom plugin fits your exact workflow, loads only the code you need, and can integrate with M-Pesa, your CRM or your internal systems.

Which custom WordPress plugin developer in Nairobi can build payment and booking plugins?

Online Creatives Kenya is a Nairobi agency that has built M-Pesa payment gateways for WooCommerce, booking and rooms managers for hotels and salons, learning management systems, an ERP for a training institute and AI chat plugins. Browse our portfolio or send a brief for a quote.

Do you build plugins that are compatible with WooCommerce HPOS and the block editor?

Yes. We declare HPOS and Cart and Checkout Block compatibility for WooCommerce plugins and build admin screens with the WordPress APIs, so your plugin keeps working as WordPress and WooCommerce update.

Will I own the plugin code?

Yes. For custom builds you receive the full source code and documentation. We also offer optional maintenance so updates, PHP upgrades and security patches are handled for you.

How long does it take to build a custom WordPress plugin?

Simple plugins take one to two weeks. Multi-module systems such as bookings with payments, or an LMS, are planned in phases, often four to eight weeks, with a working version shown early so you can give feedback.

Can you fix or extend a plugin another developer built?

Yes. We audit the code first, then fix bugs, improve security and performance, or add features without starting from scratch.
