Minimum Order Quantity (lots of little words, but still easy to understand) refers to the minimum number of products or units that a supplier is willing to produce and sell. MOQ can be set per order, per product, per size or by colour. For example, you are ordering from a company called Casca Remedies. They have an item with a MOQ requirement of 500 pieces. You need 200 pieces for your client but you would like to buy the remaining 300 piece lot for future use. The availability of this lot depends on their scheduling in manufacturing the product and their fulfilment schedule.
