Often we have to order from our suppliers with MOQ of 1000 with pre-scheduled drop qty and dates, can I put this information in StockTrim?

Yes, you can.  Each item has a ‘Minimum Order Quantity’ field that you can set. You can also set the minimum order quantity to be automatically set from your purchase order history so you don’t need to go through each one manually. There is a setting, in the top RH corner of the order plan screen, called ‘Set minimum order quantity from PO history’.
