An incoming-goods discrepancy becomes more expensive and difficult to investigate the moment questionable units are mixed with normal saleable stock. A carton count can be wrong, a variant label can identify the wrong product, transit damage can be hidden inside intact packaging, or the manufacturing specification can differ from the approved purchase. These events should not all be handled as a generic supplier complaint. A small UK trading business needs a controlled sequence that captures what arrived, protects customers, keeps the stock ledger honest and resolves both purchasing and inventory records after a decision.
The process starts with the accepted purchase order and the physical receipt, then branches according to the observed difference. A commercial short shipment ordinarily needs a quantity and supplier reconciliation; an unexplained change to warnings, electrical housing or product identity may require a qualified product-safety review before release. The Office for Product Safety and Standards provides relevant traceability and product-safety guidance where duties apply. This operational method is not a universal government-mandated goods-in form or a substitute for product-specific conformity obligations.
1. Establish the source record before booking stock
Retrieve the authorised purchase order and all approved amendments. Verify the supplier, product and variant identifiers, order quantities, units of measure, agreed revision and expected shipment details. Compare the delivery note against the order, but remember that the delivery note describes the supplier's claim about what was sent; it does not independently prove what the warehouse received.
Record receipt date, receiving location, shipment or carrier reference and the employee who performed the check. Where appropriate, retain carton and batch references. If the supplier sent an unexpected substitute, do not create a new saleable item simply because its barcode scans. The business must first establish what the goods are and whether they are authorised for the relevant order.
Make the unit conversion explicit. A purchase order for ten cartons containing twelve units each differs from an inventory receipt for ten pieces. A mistaken conversion can create fictitious stock or a false shortage that later produces unnecessary supplier claims. Check pack configuration rather than assuming all cartons contain the same number of items.
2. Count and identify affected goods by line
Compare ordered, observed, accepted and disputed quantities for each SKU and variant. A shipment may contain the correct total number of items but the wrong assortment. If eighty red units and twenty blue units were ordered, a receipt of fifty of each does not fulfil the commercial requirement even though the overall total equals one hundred. The stock system must represent the actual physical units.
Identify shortages, over-deliveries, mixed cartons and unrecognised products separately. For a partial shipment, check whether the supplier has issued a documented backorder or believes the order is complete. Do not close a line on the basis of an unconfirmed explanation. Over-delivered goods should remain subject to a purchasing decision rather than silently become a new authorised purchase.
Verify whether units are already allocated to accepted customer orders. If a missing variant affects a promise, assign a customer communication owner while purchasing investigates the supplier difference. Keep the original order and supplier resolution distinct so employees do not mistake a requested replacement for an actual shipment.
3. Preserve evidence before moving cartons
Record physical condition, external labels, product identifiers, batch marks where applicable, counts and the nature of the discrepancy. Photographs can support the case when they show the relevant condition and are linked to a specific SKU, carton or lot. A picture of an entire pallet is insufficient to establish which individual units had missing warnings or damage.
Keep documentation consistent. Name the relevant purchase-order revision, delivery note and original product specification. The receiving employee should describe observations, not speculate about fault or intent. For example, 'outer carton crushed, housing cracked on inspected unit' is more useful than 'supplier careless'. Identify what was checked and what was not.
Preserve appropriate samples or packaging where doing so helps a justified investigation. Avoid unnecessarily retaining confidential supplier documents or personal information in unrestricted shared folders. Give the claim a stable reference so purchasing, warehouse and any technical reviewer can discuss the same affected population.
4. Separate damaged or questionable stock immediately
Use a clear stock status for units that are not yet approved for sale. Depending on the operation, that may involve a designated physical area, system quarantine flag or a combination. Goods can remain physically present while being excluded from available-to-promise balances. This prevents sales and automated websites from offering inventory whose identity or suitability has not been established.
Do not automatically restrict unrelated units without reason. If the issue is confined to one carton or batch, identify that scope accurately; if traceability is inadequate, escalate rather than guessing the boundary. An authorised person must decide when held goods can be released, returned, reworked or otherwise treated.
A supplier's offer of a discount is not a product-safety clearance. A cosmetic variance that purchasing can accept does not mean technical or regulatory concerns have been resolved. The OPSS product-safety guidance addresses traceability, documentation and post-market obligations where relevant. Product category and economic-operator role determine the applicable requirements.
5. Classify the discrepancy and route it correctly
Give each discrepancy a concise category: short shipment, over-delivery, wrong variant, transit damage, specification deviation, packaging or label problem, and missing documentation. Multiple categories may apply to the same shipment, but each affected line needs an understandable factual record. A shortage should not be buried inside a report primarily about cosmetic damage, because the commercial remedy may differ.
Assign a purchasing owner to coordinate the supplier conversation and a suitable technical or quality reviewer where the facts require it. The warehouse provides counts and physical observations. Finance confirms whether an agreed credit has been actually issued or reconciled. Sales manages verified customer updates. One coordinator prevents contradictory demands or duplicate supplier claims.
Record what decision is needed from each role. A technical question about conformity should not be resolved by the employee negotiating a credit note. Equally, a straightforward count discrepancy may not justify a complex technical assessment if product identity and suitability are not in doubt.
6. Send a clear supplier claim with actionable evidence
Prepare one discrepancy file stating the purchase order, delivery date, affected SKU and quantity, observed condition, expected specification and resolution requested. Attach relevant photographs and source documents, and explain which goods remain unavailable for use. Request a written response and set a reasonable follow-up according to the commercial consequence and agreed contractual terms.
Different outcomes may be appropriate: replacement, outstanding delivery, return authorisation, accepted variance or credit. Do not assume the supplier's preferred resolution is automatically suitable. If customers need the exact missing product, a credit may settle the invoice but leave an important fulfilment obligation open. If the goods are unsafe or nonconforming, a discounted price does not make them acceptable for sale.
Track dates carefully. A supplier's promise to send replacements is not proof of dispatch or receipt. A credit request is not a posted credit. Record the actual event and the employee responsible for checking it, rather than marking the claim resolved when the first favourable email arrives.
7. Reconcile the ledger without inventing available stock
Inventory records should distinguish units received, held, accepted, returned and awaiting supplier action. Avoid booking the entire delivery as sellable and relying on a note to warn staff that several cartons are suspect. An appropriately configured system can keep on-hand quantity distinct from unrestricted available quantity; a smaller business using a workbook still needs one controlled authoritative balance.
When a replacement shipment arrives, book those actual units to the correct claim or purchase order. When a return physically leaves the premises, record the movement according to the company's inventory process. Financial adjustments must be reconciled to the original supplier invoice and any credit note, with accounting treatment determined by the appropriate staff.
Test for duplicate events. Retrying an integration after a timeout may receive the same purchase line twice, and two employees may both record a supplier replacement. Use stable references and inspect existing transactions before posting another movement. A tidy closing stock figure is not trustworthy if it was created by duplicate corrections.
8. Investigate repeated discrepancies at their actual source
After resolving the immediate case, identify whether the error came from unclear purchasing instructions, incorrect supplier picking, inadequate packaging, barcode mapping, transport conditions or a receiving procedure. Repeated shortages of one variant may reflect the supplier's case-pack convention rather than random error. Repeated wrong products may originate from a conflicting catalogue code.
Give the supplier specific feedback and test subsequent deliveries against the affected characteristic. If one supplier repeatedly ships the wrong carton configuration, update the purchase specification or ask for a verified packing method. If receiving staff apply inconsistent unit conversions, fix the internal instructions and system mapping. Do not use a generic complaint score as a substitute for identifying the cause.
Keep useful performance evidence proportionate. A single error is not a robust long-term defect-rate benchmark; many receipts with inconsistent inspection scopes are also difficult to compare. Define the denominator and which units were actually checked before producing formal trend percentages.
9. Close commercial, stock and customer actions separately
A discrepancy is fully resolved when the physical goods, purchasing agreement, inventory record, finance treatment and affected customer commitments are reconciled as applicable. These may finish at different times. The supplier may issue a credit before the customer receives a substitute; the warehouse may return goods before finance has recorded the adjustment.
Use a closing checklist with evidence of accepted stock, restricted or disposed units, replacement receipts, credits and customer communications. Name remaining owners if closure is partial. Preserve traceability needed for later product concerns and supplier performance analysis. Do not destroy useful source records merely because the purchasing task has been marked complete.
An incoming-goods workflow protects the business when employees can answer what was ordered, what arrived, which units are usable, who decided and what resolution actually occurred. Start with accurate receiving facts, restrict uncertain goods, route exceptions by consequence and close every relevant system. That avoids converting a single difficult delivery into continuing inventory ambiguity.
Goods-in discrepancies and the traceability evidence needed for a safe decision
Receiving records are not just evidence for a credit note. For goods subject to product-safety rules, the identification of affected items can be important if a discrepancy later proves to indicate a wider defect. UK Office for Product Safety and Standards (OPSS) guidance identifies the manufacturer and importer name and address, where relevant, and a product or batch reference as important traceability information. Its guidance also highlights monitoring safety issues and acting on risks identified after products enter the market.
A practical discrepancy file should therefore distinguish commercial variance (for example, 80 units shipped against 100 ordered) from potential safety or conformity variance (for example, unknown model identifiers, missing warnings, damaged electrical housings or instructions that differ from the assessed product). The first normally needs a stock and supplier reconciliation; the second may also need a product-safety review before release. Merely resolving a short shipment commercially is not evidence that held items are safe to sell.
Record the purchase-order revision, supplier delivery note, received date, SKU, variant, carton or batch markings, quantity accepted, quantity quarantined and the decision maker. Link photographs to the specific carton or batch, not merely to the shipment overall. Do not release held goods into the sellable balance until the relevant issue is resolved; where safety is in doubt, escalate to the appropriate competent person rather than treating a supplier credit as a safety clearance.
Scope: Exact documentation and conformity obligations differ by product category and market. The example record is an operational recommendation, not a universally prescribed UK goods-in form.

Commercial shortage or possible product conformity issue?
A missing count and an unverified product characteristic call for different controls, even when both appear on the same delivery note.
| Criterion | Quantity or commercial variance | Potential safety or conformity variance |
|---|---|---|
| Typical evidence | Physical count, PO, case quantities and supplier delivery note. | Actual unit, label, lot, specification and relevant technical documents. |
| Immediate stock action | Book only accepted actual quantities; reconcile outstanding balance. | Restrict affected uncertain units pending qualified review. |
| Decision authority | Purchasing confirms replacement, return or credit terms. | Appropriate competent reviewer establishes release requirements. |
| Customer consequence | Verify whether shortage affects an accepted order. | Do not release questionable goods to meet a delivery promise. |
| Closure proof | Actual receipt, return, order and financial reconciliation. | Documented assessment and authorised stock disposition. |
| Limitation | Credit settlement does not prove all goods are suitable. | Visual inspection alone does not prove batch-level conformity. |
Decision: classify by issue, preserve affected stock and close the actual physical and commercial outcomes independently. Side A: Operational quantity reconciliation based on the purchase order and receipt record; an editorial business method, not a prescribed regulatory form. Side B: OPSS manufacturer and importer product-safety guidance, scope: applicable product and traceability duties. Product-specific compliance must be assessed separately.
