Advanced catalog services

As a supplier, you are required to use advanced catalog services to add all rich item data, including images, for any items you wish to sell on the BrandX website. To learn more about advanced catalog services, see Advanced Catalog Services for Suppliers.

Looking for more information on managing your content with advanced catalog services? View and enroll in the Managing Your Content training course in Rithum Learn, which provides interactive, on-demand business and system training.

Note: Not every retail trading partner on the platform uses advanced catalog services, which is different from the basic Catalog templates that are used to provide product/item data to your retail partner. For more information about uploading default Catalog/Inventory templates using the Inventory page, see Creating or Updating Inventory.

Packing slips

Packing slips can be downloaded from the platform. If you prefer to create your own packing slips, this document provides instructions for replicating packing slips for BrandX. Once you have created your packing slips, please submit samples to BrandX for approval.

EDI documentation

If you are going to exchange EDI documents with Rithum for BrandX, you will use the standard EDI specifications.

Note: In the EDI specifications, there are two versions for the 850 file: 4010 and 5010. For BrandX, we recommend you use the 5010 version for 850 files. All other files (846, 856, 870, 810) will use the 4010 version.
