Why purchase orders and receiving records must be compared item by item
When purchasing from multiple suppliers in China, goods often arrive at the same fulfillment warehouse in batches. If inbound receiving is registered only based on the supplier's shipping notice or courier waybill, three problems easily arise: the purchase order says Style A, but what actually arrives is an old version of Style A; the purchase order quantity is 500 units, but only 480 units actually arrive and no one notices; the same SKU arrives in three batches, the batches get mixed together, and later picking and packing cannot trace them. What the purchase order to warehouse receiving match workflow China aims to solve is aligning three sets of data — the purchase order (PO), supplier delivery information, and actual warehouse receiving records — so that inventory quantity, SKU, and batch are confirmed clearly at the inbound stage.
This process is not financial reconciliation, but a check at the warehouse operations level. Its goal is: every inbound shipment can answer three questions — which purchase order it belongs to, which SKU it corresponds to, and what the actual quantity of this batch is.
What each of the three data sources contains
| Data source | Key fields | Frequently Asked Questions |
|---|---|---|
| Purchase order (PO) | PO number, SKU, order quantity, unit price, delivery date, supplier name | The same SKU spans multiple POs; the quantity was changed midway but the version was not updated |
| Supplier delivery information | Supplier name, shipping date, number of cartons, contents inside the carton, tracking number, PO number | Only the total quantity is written, not the SKU; the contents inside the carton do not match the actual packing |
| Warehouse receiving record | Arrival date, number of cartons, actual SKUs received, actual quantity received, outer carton condition, photo records | When multiple cartons are mixed, register by carton without breaking down by SKU |
The common anchor for the three sets of data is the PO number and SKU. As long as these two fields can be matched, discrepancies in quantity and batch can be traced to the specific step.
Standard operating steps for receiving comparison
Step 1: Build a pending-receipt list before arrival at the warehouse
Before the goods arrive, compile the PO numbers, SKUs, ordered quantities, and supplier names expected to arrive at the warehouse this time into a receiving checklist. Reserve three columns in the checklist: actual received quantity, discrepancy quantity, and discrepancy reason. This way, receiving becomes "checking against the list" rather than "registering whatever arrives."
Step 2: Register by carton, then break down by SKU
Register outer cartons by carton number first, recording the number of cartons, whether the outer cartons are damaged, and whether the seals are intact. After opening the cartons, count item by item by SKU, breaking down the actual contents of each carton to the SKU level. When multiple suppliers are mixed in the same shipment, it is recommended to place them in zones by supplier to avoid mixing similar products from different POs together.
Step 3: Three-way comparison, flag the discrepancy type
Compare the actually received SKU and quantity item by item against the purchase order and supplier delivery information, and classify discrepancies into the following types:
- Quantity shortage: Actual received is less than the purchase order or delivery note
- Quantity overage: Actual received exceeds the purchase order
- SKU mismatch: Inbound SKU does not match the purchase order
- Version or batch mismatch: Same SKU but different color, specification, or production batch
- No matching PO: Inbound goods cannot be matched to a purchase order
Step 4: Photograph and keep records on file
Perform basic quality inspection and take photos of the discrepancy items, recording the outer carton, inner packaging, product labels, and quantity count results. The photos and records are the basis for subsequent communication with the supplier and for deciding whether to reship or accept the short shipment.
Step 5: Confirm inventory status before moving into available inventory
Goods with no discrepancies can be directly registered as available inventory; goods with discrepancies should first be marked as pending confirmation, and only after the purchaser gives handling instructions should it be decided whether to shelve them and whether they will participate in subsequent picking and packing.
Discrepancy handling process
- Quantity shortage: First confirm whether it was shipped in multiple batches and whether there are still boxes in transit, then decide whether to request replenishment from the supplier.
- Quantity overage: Confirm whether it is a free gift, spare item, or shipping error, to avoid counting non-purchased goods as available inventory.
- SKU mismatch: Pause shelving, take photos and send them to the purchaser to confirm whether it is a replacement item or a shipping error.
- Batch mismatch: If the product has version iterations, the purchaser needs to confirm whether to accept that batch.
- No matching PO: Store separately in isolation, and wait for the purchaser to supplement the purchase order information or arrange a return.
A few operational suggestions to make matching smoother
- Require suppliers to clearly state the PO number and SKU in the delivery information, rather than just writing "one box of goods."
- When the same SKU arrives in multiple batches, record the batches by warehouse arrival date for easy traceability later.
- Sync purchase order changes (quantity changes, SKU changes) to the pending receipt list in a timely manner to avoid checking against an outdated version.
- Use a fixed carton mark format for high-frequency suppliers to reduce the cost of identifying goods after opening cartons.
- A unified template for discrepancy records makes it easy for procurement, warehouse, and suppliers to communicate using the same set of terms.

Frequently Asked Questions
What if the supplier does not provide a PO number?
You can require suppliers to include at least the buyer's name, SKU, and quantity in the delivery information, and the buyer can map it in the pending receipt list. Goods without a PO number should be marked separately to avoid confusion with existing purchase orders.
How can counting efficiency be improved when multiple boxes are mixed together?
Arrange items by supplier and PO. First register by carton, then split by SKU. When necessary, count high-value SKUs piece by piece, and for low-value standard items, do sampling counts and record the sampling ratio.
How long does discrepancy confirmation take?
It depends on how quickly the buyer responds. What the warehouse side can do is promptly record, take photos, and mark the status as pending confirmation. The specific processing pace is subject to what both parties agree.
