If your enterprise is a "producer" type (you checked the corresponding box in your profile settings), you can now add products and related variants to your producer catalog. These products can be added in bulk by importing a csv file (excel file saved in csv format).
The price entered for each product in the producer catalog is the full amount the producer will receive from a sale- hence a 'wholesale' price. Hubs (distributors) can add their fees for admin, transport and packing etc on top using fee options in Shipping Methods, Payment Methods or Enterprise Fees.
If a hub wishes to change the price of a producer's products without using the Enterprise, Shipping or Payment Method Fees strategy then it is best to use our Inventory feature. By adding products to their shop inventory, hubs create a second catalog, independent of the product catalogs of their suppliers. Prices and stock levels in the Hub Inventory can be altered by the Hub without impacting on producers' 'master copies'.
For irregularly priced products, such as a whole chicken with a price that varies from chicken to chicken depending on weight, there is an option to set a price 'per chicken' which can then be adjusted at the time of delivery to the specific piece of meat/vegetable.
The "Bulk Buy Option" page details how Buying Groups can use OFN to organise and record bulk purchases. For example, if a group buys rice in 25 kg bags then this function can help distribute the rice between customers based on a weight range they request on purchase.
