To allow the Intelligent Algorithms to recommend the best shipper you will have to go to Configuration > Intelligent Algorithms > Shipper and enter the data (from the shipper contract) for each shipper configured on Poleepo on your store.

After entering the data relating to your contracts, Poleepo will recommend the estimated cost of shipments for each configured shipper.

Furthermore, by analyzing the real costs of shipments made over time, the algorithm will be able to indicate with ever more precision the actual and real cost and will indicate the net profit taking into consideration, in addition to the sales channel commissions, also the cost of shipping.
