For Multi-Vendor operators

Add-ons that work in the vendor panel, not only in the admin

Most add-ons treat Multi-Vendor as a price tier. Ours are tested in the vendor panel too: vendors manage their own settings within the permissions you grant.

  • Vendor-panel screens and per-vendor settings, controlled by your admin settings
  • Tested on Multi-Vendor 4.17.2 and 4.21.2 before each release
  • Multi-Vendor Ultimate licenses cover every storefront of one installation

FAQ

Questions store owners ask before buying

Anything else? Ask us; a developer answers within 1 business day.

Which CS-Cart versions do your add-ons support?
Every released add-on supports CS-Cart and Multi-Vendor 4.17.2 – 4.21.x on PHP 7.4 – 8.3. Before each release we test it on CS-Cart 4.17.2, Multi-Vendor 4.17.2 and Multi-Vendor 4.21.2 (PHP 8.3, Nova theme, full page cache on and off), and the product page lists the exact builds.
Do you change CS-Cart core files?
No. Everything runs through CS-Cart hooks and template overrides, so CS-Cart upgrades and a clean uninstall keep working. The developer guide of each add-on lists the hooks it uses and provides.
What happens when the 12 months of updates end?
The add-on keeps working. Only updates and support pause. You can renew at any time at 50% of the current price.
How many add-ons can I buy today?
17 add-ons are on sale now, and 84 are planned. Each one opens for sale when its test plan passes on the named builds. Leave your email on any product page to hear when it ships.
Can you build something we cannot find in the catalog?
Yes. We build custom add-ons and adapt ours to your store and theme on a fixed quote, with the same standards: hooks only, tested on your CS-Cart version, documented. Request custom development.
Do I need a separate license for staging?
No. A license covers every subdomain of your store domain, such as staging.yourstore.com, and local development hosts (localhost, private IP addresses, *.local, *.test) are always free. One license covers one production installation.
