• do not know the deadlines to place purchase orders for items
• do not know what materials to buy
• do not know the optimal quantities of items to buy
• do not know the scheduled dates to receive items from suppliers
• do not know when products will be available to customers

As a result, they are likely to

• buy too many items
• buy too few items
• place purchase orders too early and thus deteriorate their organizations' cash flow
• place purchase orders too late
• push suppliers too much
• be squeezed by customers

PostERP is MRP capable. Moreover, it processes not only items, but also

• lots or serial numbers of items in electronics, tile, mechanic, etc. industries
• sizes of shoes in footwear manufacturing

Further, PostERP massively converts MRP run results to these orders:

• purchase requests (which in turn can be converted in batch to purchase orders according to preset weights)
• manufacturing orders
• subcontract orders
