Built forCS-Cart

What it does

For Multi-Vendor marketplaces that sell plans. Core vendor plans limit products, revenue and categories, but not how much a vendor uploads per product. This add-on adds limits per plan: images per product, images in the full description, short description and promo text, size per image, attachments per product and size per attachment. For Multi-Vendor only, on 4.17.2 to 4.21.x. It limits product media; Vendor Storefront Pro, a separate add-on, controls shop page sections and featured products.

How it works

Enter limits for all plans on one page, or in the plan editor. Vendors see a meter on the product page, such as 6 of 8 images. Over the limit, new images are refused and text is still saved. Replacing an image is always allowed. The server checks every path: the panel, direct requests, the APIs, bulk edit and CSV import. Products above a limit after a downgrade stay online unchanged; the vendor can edit, replace or remove, but not add.

Features

  • Images per product, per plan
  • Separate image limits for the full description, short description and promo text
  • Maximum image size and attachment size per plan
  • Attachments per product, per plan
  • Server-side checks for panel, direct requests, REST API, GraphQL, bulk edit and CSV import
  • Nothing stored is deleted, also after a plan downgrade
  • Replacing an image always works, also at the limit
  • Messages that name the plan allowing more, with a link to compare plans
  • Usage meter on the vendor's product page
  • Limits shown on the plan cards in the vendor panel and on the storefront
  • List of vendors at the limit, with counts per type
  • One page for all plans, plus fields in the plan editor
  • Administrators are never limited
