What to do if the packing slip shows a shortage?

If the packing slip indicates a shortage, first verify the items received against the packing slip to confirm the discrepancy. Then, contact the supplier or retailer's customer service to report the issue and provide them with the relevant order details. Keep a record of all communications and any supporting documentation, such as photos of the received items. Finally, follow any instructions provided by the supplier for resolving the shortage, which may include processing a refund, sending the missing items, or issuing a credit.
