As a part IdoSell integration with the WMS, we provide the product picklist, which natively cooperates with other functions of your online store. The list of products being picked is a sort of "cheatsheet", which groups products in such a way that during one cycle a warehouse employee can download products for multiple orders at a time and then transport them to the picking area.
Our picklists support both picking the entire order at once, as well as sequential product picking by remembering which products have already been packed.
