dropship360 aims to seamlessly connect Merchants to Suppliers and Suppliers to a single Portal.
As a Merchant you will most likely be working with Suppliers prior to installing dropship360.
Follow the instructions to add the Supplier to the Logicbroker Portal - found here. And contact them to tell them to connect to the Portal.
IMPORTANT: DO NOT ADD A SUPPLIER TO THE PORTAL WITHOUT FIRST CONNECTING YOUR MAGENTO SYSTEM.
Next, make sure that products are attached to the appropriate Supplier. See here for more details.
And finally, the Vendor/Supplier must be in the Active column under Supplier Ranking. Check by going to dropship360>Supplier Management. Remember: the Supplier Code must match the Vendor ID assigned to that Supplier in the Logicbroker Portal.
