About Kavio Labs

Kavio Labs Software Limited is an independent developer of add-ons for CS-Cart and CS-Cart Multi-Vendor. We build for stores that have to keep running through core upgrades, theme changes and busy seasons, so we keep our add-ons small, hook-based and documented.

How we build

  • No core file edits. PHP hooks, template hooks and schema extensions only, so core upgrades stay safe and uninstalling leaves no traces.
  • Multi-Vendor from the start. Every add-on is tested on Multi-Vendor, with vendor panel permissions and per-vendor settings where they make sense.
  • Tested builds, stated plainly. Every release lists the CS-Cart and Multi-Vendor builds it was tested on and the range it supports. A new core version is added only after it passes our QA.
  • Licensing without the hassle. Keys right after payment, staging on your subdomains included, and add-ons that keep working when updates end.
