3 PROBLEMS WE SOLVE FOR WORDPRESS STORES

As a custom WordPress plugin development company, we spend most of our time on the same three problems. They are rarely about a missing feature. They are about functionality that was bolted on badly and stopped surviving updates.

SEE OUR SERVICES

  • Functionality That Breaks On Update

    Changes made to theme files or third party plugins disappear the moment those get updated.

  • Plugin Conflicts And PHP Errors

    One plugin fights another, the site goes white, and nobody can tell you which one caused it.

  • Checkout And Shipping Failures

    Rates that never appear, orders that never complete the faults that stop a store taking money.

WHY EXTONIFY

6 REASONS TO WORK WITH US

What you actually get when you hand a WordPress or WooCommerce problem to a plugin company rather than a general web agency.

  • Focused functionality

    We build the functionality you actually need, not a bloated plugin you will spend the next three years maintaining.

  • Update safe by default

    Work is built against WordPress and WooCommerce APIs and extension points, not edits that vanish on the next update.

  • Real WooCommerce depth

    Checkout, cart, shipping carriers, live rates and order workflows the parts that decide whether a store gets paid.

  • We ship our own plugins

    We do not only sell development. We publish and support our own plugins, so we live with the same code you do.

  • Nine years of practice

    Nearly a decade of WordPress and WooCommerce work sits behind every plugin, customization and fix we hand over.

  • Plain answers

    You are told what is actually wrong, what it takes to fix, and what it costs before any work begins.
