Auto Parts Receiving Checklist: Keep Counts Accurate
By Ty Fisher, founder of Fisher Software
A delivery arrives while the counter is busy. Someone checks the cartons, puts the parts away, and marks the purchase order received. Later, the inventory count is wrong. For an independent auto-parts or supply business, receiving deserves its own short routine: confirm exactly which part arrived, what one unit means, and how much is ready to sell before changing the stock record.
In short: Check the part number and selling unit, count usable stock, record shortages separately, and put each item in its assigned location. Keep returns and used cores out of sellable quantities. The checklist below is a suggested operating routine; the worked example is hypothetical.
1. Match the exact part, not just the carton
Start with the supplier, purchase-order number, manufacturer and part number. A similar description does not establish that two parts are interchangeable. Confirm the ordered specification against the label and supplier documents before putting anything into a sellable location.
Keep supplier catalog references separate from your own SKU when they differ. Do not create a second product record simply because another supplier uses a different reference for the same item. Investigate the match first; never merge records solely because the names look alike.
- Check manufacturer and full part number, including suffixes.
- Confirm left/right, dimensions, connector or other relevant specification.
- Identify substitutions explicitly and obtain the appropriate purchasing approval.
- Set an unknown or mismatched item aside until its identity is resolved.
2. Decide what one inventory unit means
A box can mean one item, a pair, a kit or a case. Your purchasing quantity and your selling quantity may be different. Write the relationship into the item record or receiving instructions so the next employee can apply the same conversion.
GS1 US distinguishes individual items, inner packs and cases as separate packaging levels. A barcode on a shipping case therefore should not be assumed to represent one individually sold part. Confirm what the scanned code identifies and how your system maps that package to stock units.
For a brake-pad set, one selling unit might be one complete boxed set. For bottled fluid, one selling unit might be one bottle even though you purchase cases. Follow the product packaging and your actual selling practice; there is no universal multiplier for every parts category.
3. Count usable units before posting the receipt
Compare what physically arrived with what was ordered. Inspect for damaged packaging, missing components or a wrong item inside an otherwise correct box. Record only the quantity you have verified under your receiving procedure.
Hypothetical example: you order four cases of fluid with six bottles per case, expecting 24 bottles. Three cases arrive, containing 18 bottles, and two bottles are damaged. If your sellable inventory excludes damaged goods, add 16 sellable bottles, record two damaged bottles separately, and leave six bottles outstanding with the supplier. Do not mark 24 sellable bottles received.
This example separates a supplier shortage from damage. That distinction helps the person resolving the order ask for the right replacement, credit or backorder update. The exact screens and adjustment steps depend on the system you use.
4. Keep partial shipments visible without ordering twice
An open purchase order should explain what is still expected. Record the delivered quantity, outstanding quantity, supplier response and next review date. If the supplier cancels the remainder, document that decision rather than leaving an old backorder indefinitely.
Before creating a replacement order, check the open order and whether the supplier still intends to deliver. Otherwise, solving a shortage today can create excess inventory when both shipments arrive next week.
- Link packing slips and discrepancy notes to the original purchase order.
- Give one person responsibility for resolving the shortage.
- Record the promised delivery date as a supplier estimate.
- Close the remaining quantity only when fulfilled or deliberately canceled.
5. Separate customer returns and used cores
A customer return is not automatically ready to sell. Verify the item, packaging, condition and your return rules before adding it back to available stock. An opened box with an unknown part inside should not inherit the count of the label on the outside.
Where your supplier arrangement involves a used core, keep that used item physically and operationally separate from new or remanufactured sellable stock. A core awaiting supplier return should not increase the quantity a counter employee promises to a customer.
A simple separate log can record the associated sale or return, supplier reference, item identity, date sent and credit status. Use your supplier agreement to determine eligibility and deadlines. Do not assume general inventory software also manages core credits or vehicle fitment.
6. Put stock away and verify the location
Receiving is incomplete if the quantity is correct but nobody can find the item. Label the shelf or bin, put away the accepted stock, and update the recorded location using the process your system supports.
Keep inspection stock, customer-held items and outgoing supplier returns visibly distinct from stock available at the counter. If you use a separate reservation process, reconcile it before promising an item. A company-wide quantity alone does not tell staff what is available in a particular shop.
A short checklist for the receiving bench
- Supplier and purchase order matched.
- Manufacturer, part number and specification verified.
- Selling unit and case conversion confirmed.
- Delivered, damaged and outstanding quantities recorded separately.
- Returns and used cores kept out of sellable stock.
- Accepted stock placed in its assigned location.
- Receipt saved and unresolved exceptions assigned to someone.
- A second person can find the item and explain the new quantity.
Test the process with a sample purchase order
Choose a small set of products: an individually sold part, a boxed set and an item bought by the case. Walk through ordering, checking the delivery, converting quantities and finding the stock afterward. Record any step that depends on somebody remembering an unwritten rule.
