An over-delivery can look like a pleasant stock surprise, but extra units create a commercial and inventory question. The business ordered one quantity, physically received another and may later be invoiced for either amount. If staff simply receive everything against the purchase order, the record can imply that the additional quantity was authorised. Small product traders should identify the excess, keep it visible and decide deliberately whether it will be accepted, returned or otherwise resolved with the supplier.
Count the delivery before changing the purchase order
Confirm the physical quantity at the correct SKU and pack level. A supposed over-delivery may actually be a carton conversion error or mixed product. Check supplier references and the ordered unit of measure before concluding that extra stock arrived. Do not amend the purchase order merely to make the expected and received numbers match; first establish what was physically delivered.
Separate ordered quantity from excess quantity
Record the amount that matches the authorised order and identify the additional units as an exception. The exact system treatment will depend on the business's tools, but staff should be able to see that the excess did not originate from the original purchase decision. This protects purchasing history and makes later supplier or invoice discussion much easier to understand.
Check whether the supplier intended the extra units
Contact the supplier through the normal purchasing route where the reason is unclear. The excess may reflect a packing error, an agreed tolerance that was not visible internally or another documented arrangement. Avoid assuming the goods are free or automatically owned by the business. Record the supplier's response and any agreed next action so warehouse and accounts work from the same position.
Keep unresolved excess stock from normal allocation
Until the commercial position is clear, avoid promising the extra units to customers merely because they are physically present. If the business later needs to return them, allocating them to orders creates a second problem. Use an appropriate exception or quarantine status while ownership or acceptance is unresolved, keeping the stock identifiable without treating it as ordinary saleable availability.
Review the invoice independently
The supplier may invoice the ordered quantity, the delivered quantity or issue a later correction. Match the invoice to both the purchase order and confirmed receipt. Do not alter physical stock to compensate for a billing difference. Accounts needs to know which units were authorised and which are under discussion so any payment or credit process remains connected to the actual goods event.
Accept additional stock only through a deliberate decision
If the business chooses to keep the excess, document the commercial agreement and update the purchasing record appropriately. Consider whether the extra quantity makes sense for demand and stockholding rather than accepting it simply to avoid return administration. The decision should be made by the person authorised to commit the business, especially where the additional units affect cash, storage or range plans.
Return excess units with traceable quantities
If the supplier requests a return, keep the units separate and record what leaves the warehouse. Confirm the SKU, quantity and relevant supplier reference so the return closes the same exception created at goods-in. Avoid reducing stock with an unexplained adjustment after dispatching the goods back; the record should show why the units entered and why they subsequently left.
Review repeated over-deliveries with the supplier
Recurring excess quantities may indicate pack misunderstandings, order-unit mappings or a supplier fulfilment pattern that needs clearer agreement. Use actual purchase and receipt records to identify the cause. A controlled over-delivery process ensures that physical stock, purchasing authority and supplier accounting remain aligned. Extra units are then handled as a decision requiring evidence rather than quietly absorbed into inventory because they happened to arrive.
