This article will teach you how to create a tenant-only product field (text or dropdown) on Edit Product and optionally show it on B2B search cards.

Specs such as Load Index and Season come from the Global Catalog. A custom field is yours — for example Tire Type with NEW and USED. Values stay on your catalog product and are not sent to Global Catalog review.

Edit Product Custom Fields with a Tire Type dropdown, and B2B Settings Product Card Specs with Tire Type checked

Steps

Open a product in Books → Products & Services (or Sync Inventory → Edit Specs, or WMS catalog). Specifications includes Custom Fields.
Click + New field. Enter a name (for example Tire Type), choose Text or Dropdown, and pick whether it applies to Tires, Wheels, and/or Parts.
For a dropdown, add the options (NEW, USED). Save field. The new input appears on matching products.
Set the value on this product and click Save Product. The field is stored on your catalog item only.
To show it on the B2B portal, open Sync → Sales Channels → the B2B portal → B2B Settings. Under Product Card Specs, check the custom field for Tires, Wheels, or Parts, then Save B2B Settings.
Search the portal for a local catalog product that has a value. The card shows the label and value (for example Tire Type: USED).
To stop using a field, Edit it from Custom Fields and choose Archive field. Existing values stay readable; the field is hidden when empty.

Conclusion & best practices

Custom fields do not become B2B search filters in this version, and they do not print on invoices or quotes. Vendor-feed rows with no matching local catalog product will not show a custom value. Related: How to choose the product name on B2B search cards?.
