You can switch your distributors for any current purchase orders in the Price Comparison Module; however, this only changes the distributor for that order. If you would like to change that product's distributor for the foreseeable future, go into the Dual Products tab of the My Products module. From here, select the product you would like to change distributors for and then edit. Then you can pick your new distributor from the "Select Default Distributor" dropdown.
Products are highlighted red in the Beverage Journal to indicate that they have already been added to the My Products Module.
If products in your store's inventory do not exist in BevJournal, you can manually add them by clicking "Add Outside Products". From there, fill in the correct information and click "Add New Product".
