The short answer
A SKU card is an internal reference photographed with an item. GrimLister can use readable card information during preparation to help carry the SKU, bin location, weight, and dimensions into the listing workflow. Check the extracted values before publishing.
Make your internal card easy to read
Use large, plain lettering and separate the fields. Photograph the card straight on with enough light to read every number. Keep the card with the correct item’s photo sequence, typically at the end.
For example: “SKU: A104; BIN: 5; WEIGHT: 1 lb 8 oz; BOX: 15 x 8 x 6 in.” This is a formatting example, not a recommended package for any particular item. Include units so a number cannot be mistaken for pounds, ounces, or inches.
Distinguish a location from a unique item
A bin can hold many items. If “Bin 5” appears on several cards, it tells you where to look but does not uniquely identify a product. Combine a bin with a distinct item code when you need one-to-one identification.
Keep this convention consistent across your physical labels and inventory records. After a sale, you should be able to match the sold item to the object on the shelf without guessing between similar items.
Treat shipping values as packed measurements
Record the final package when possible, including the carton and protective material. If the item is not packed yet, use a known suitable box template and verify the result before publishing.
Check separate pound and ounce fields, all three dimensions, and the units. A clearly photographed “15” can still be read incorrectly, so compare the prepared values with the actual card.
Keep internal reference cards out of buyer-facing photos
A SKU card exists to support your workflow. Before publishing, inspect the final photo selection and make sure internal reference cards have been recognized and excluded from the buyer-facing photo set.
Your listing photos should show the actual item and relevant details. Do not make buyers sift through storage instructions to understand what is for sale.
Common questions
Do I have to use a SKU card?
No. You can group photos and enter or correct inventory and shipping information without a card. Cards are a shortcut for sellers who use them in their photo routine.
Can the same bin number appear on multiple items?
Yes. A shared bin is a location. Use a separate item identifier when you need to distinguish several products in that bin.
