Zen Cart custom software development, Zen Cart modules, Zen Cart Expert eCommerce with Zen Cart!

The Zen Cart Expert


My name is Scott C. Wilson and I am That Software Guy. I am a Zen Cart expert. Now lots of people claim to be a Zen Cart expert (or a Zen Cart master or a Zen Cart guru), but you may want to look for supporting evidence instead of just taking their word for it. What proof do I offer? You can look at my testimonials, plugins, custom work, and GitHub commits. No one has more. And I've been developing with Zen Cart for 15 years. I am the only independent software developer who is allowed to advertise on the Zen Cart forum.

My Zen Cart forum ad

You can see my ad on the Services tab on the Zen Cart forum.

I’m a software developer. But unlike most software developers, I have also done both product and project management. Most software developers have to be told exactly what needs to be built, but I can work with you to help you figure out what you need. Then, I can help you stack rank your todo list so that the most valuable features are done first.

Here's my interview with tech journalist Ramon Ray:


If you have - or want - an eCommerce website for your product or service business, and you sell with Zen Cart (or osCommerce, OpenCart, BigCommerce, or Shopify), you're at the right place. I have been helping small businesses improve their eCommerce operations since 2006. I create reliable, maintainable software customizations that work the way YOUR business works, and all for a reasonable price within a workable timeframe. What can I build for you? Or do you just need Zen Cart Support or a Zen Cart Upgrade? I can help there too. Talk to me and see - no one works harder for your small business selling online.

Current Status

  • I'm getting my software updated to run on PHP 8. If you are testing PHP 8 and encounter an issue with one of my plugins, please check the plugin's help page to see if an update is available. If it hasn't been done yet, let me know and I'll get it fixed.
  • Development is underway on Zen Cart 1.5.8. You can follow the excitement on the Zen Cart Github page.
  • The current release of Zen Cart is 1.5.7. Many improvements have been made over the prior major release (1.5.6), which was first shipped at the end of 2018. (Read more...)
  • The Zen Cart documentation has been moved to Github so that anyone can update it. You can see how it looks at docs.zen-cart.com. It uses Hugo and the Docsy template on the Netlify platform. (Read more ...)
