Assigning, updating, and maintaining an accurate connection between products and vendors is a crucial step toward better reordering and tracking.
Here are the recommended options for updating and assigning products to your vendors (and vice versa):
From the Vendor page
While you're creating a vendor or editing one, you will be able to assign or edit the products applied to the vendor.
Either way, when you're in a vendor profile, click "Edit Products" as shown here, to edit and add to the list:
The "Filter" icon can help narrow down what products to assign to the vendor.
For example, you can use the "Filter" icon to narrow down a particular product's status, locations, categories, and vendors. You can also filter by time-related options, like products that were "created on or after" a chosen period.
NOTE: If you want to see all of your products, remember to hit "Load All."
Remember to hit "Done" and "Save" when finished.
via Bulk Upload
To connect products and vendors via spreadsheet, use bulk uploads. In particular, these three options will allow you to connect a vendor to your products/variants:
Create Products and Variants
Create Products with Attributes
Edit Variants
If you're not familiar with bulk uploads, learn more about them here.
Pro Tip
Make sure the vendor name is copied exactly and separated from the other vendors with a comma.
While creating/editing a product
From your Catalog page, when creating/editing a product, you can assign it's variants to a vendor from the individual products Vendors section as shown here:
Things to Note:
When creating a purchase order for an existing vendor, if you use the "Create New Item" button, the product will automatically be assigned to the vendor.
