Direct answer: Purchase order and reorder software should compare available stock with an approved minimum and target level, suggest a quantity that respects pack size, and create a draft order. A person approves supplier sending. Partial receipts update stock once, leave the balance open as a backorder and preserve every correction.
Define minimum, target and pack size
A reorder suggestion is only as useful as its item settings. Use current available stock, approved open orders, the target quantity and supplier pack size so the draft does not over-order.
Keep supplier sending behind approval
The software can prepare a draft, but a named person checks the supplier, prices, quantities and delivery details before it is sent. V1 should never place or send a purchase automatically.
Receive partial deliveries exactly once
Post only the quantity received, retain the remaining balance as a backorder and use a stable receipt reference to block duplicate posting. Corrections retain the original receipt instead of deleting it.
