To create accounts for retail vendors who will be responsible for their own inventory additions/deletions etc., you can check the box within the contract screen next to Sales Split %. Once the Vendor box is checked and you have a Pro Subscription, they will be able to edit their inventory via the Portal. Right now, you will need to print their pricing labels for them.
Also, if you adjust their sales split % at any time, Rose will ask if you want to apply that new split to all existing inventory. Choose whether you want to do this or not. If you update existing inventory with the new %, this will override any and all splits currently set for that vendor's inventory.
Note: Vendor inventory edits via the Portal require a Pro subscription.
