Retailer Compliance and Chargebacks: Packing Slips, Labels and ASNs at a 3PL

I spend a lot of time on retailer compliance because most chargebacks I see are not mystery events. They come from a missed detail that was visible before the order left the dock. At a 3PL, my job is to make those details repeatable.

Start with the routing guide. I keep a current copy for each retailer and read the sections that affect my SKUs, not just the summary page. I note ship-to requirements, carrier selection, label placement, and any pack slip rules. If the guide changes, I update our warehouse work instructions the same day. When I tour a 3PL, I ask how they store retailer-specific requirements and how they prove the right version was used.

For ASNs, I check before transmission, not after. I confirm the shipment ID, carton count, tracking numbers, and item quantities match the physical load. I also confirm the ASN is sent within the retailer’s window. If the warehouse sends an ASN early or late, the receiving system may reject it even when the cartons are correct.

Labels get a simple check at packing:

• Barcode scans on the first try
• Carton label matches the ASN and packing list
• Required retailer label is in the specified position
• No old labels remain under the new one

Packing slips need the same care. I compare the slip to the order, confirm the SKU and quantity, and check that any required return or PO information is present. A clean slip helps the retailer’s receiving team and gives me evidence if a chargeback appears.

I keep photos of labels, sealed cartons, and the packing slip for each shipment. I also save ASN confirmations and carrier scans in one folder tied to the order. If a chargeback lands, I can respond with documents instead of guesses.

When I need to compare warehouse options or confirm who handles retailer compliance, I use a 3PL warehouse directory to narrow the list and then ask direct questions. I also verify every requirement against the retailer’s and provider’s current terms. Compliance is mostly a habit of checking the same few things every time.
