With serial tracking every single unit of an item has its own serial number. QrX asks for it when the unit is received and again when it is packed, so you always know which unit went to which order and a unit can never ship twice. For items that you track per lot, the recall list shows every order that shipped units of one lot. Serial tracking needs Full WMS with the module Serial numbers switched on in Settings > Warehouse > Stock. The recall list needs the module Lots and expiry dates.

Open the stock item, go to the Lots and expiry tab and choose under Tracking: Serial (every unit has its own serial number, scanned at receipt and when packed) or Lot and serial (every receipt needs a lot code and every unit its own serial number).

Open the receipt in Warehouse > Inbound and enter the quantity of the line. A serial-tracked line shows the button Serials 0 / 5 (scanned / needed). Click it and scan the serial number of every unit, or type it and press Enter. When every unit has a serial number, confirm the line as usual.

Scan the product as usual. For a serial-tracked item the station shows Scan the serial number with "unit 1 of 3". The next scan is the serial number on the unit. Press Esc or Cancel to stop the prompt. A barcode that holds both the product and the serial number books both in one scan. The scanned serial numbers show under the order line. Every unit needs its own scan, and the manual "+1" is not available on these lines.

Some pack stations only accept scans. When the serial label is worn or does not scan, a colleague whose role allows pack overrides sees the field Serial number does not scan? Type it here. Type the serial number and confirm with Use this serial number. The typed serial number is checked exactly like a scanned one. Colleagues without that permission ask a team lead.

When the order ships, its serial numbers get the status Shipped. When you abandon the order at the station or the order is cancelled, the serial numbers go back in stock.

The Serial numbers tab of the stock item lists all serial numbers, the newest first. Search by the start of a serial number and filter by status: In stock, Reserved (scanned for an order that has not shipped yet), Shipped, Returned or Scrapped. A serial number in stock can also be Blocked. Click a serial number to see its history with the date and the user. Actions per serial number:

Open Warehouse > History and use the card Trace a serial number. Scan or type the serial number. You see the item, the status, the warehouse, the lot, the receipt it came in on, the order it was shipped with (with its order number, which opens the order in Transactions) and its history. A unit that came back and was sold again shows both orders.

A label printed outside the pack station, for example from the Transactions list, does not ask for a serial number. QrX never blocks such an order. It counts the units per item, so you can check them afterwards.

When units of an item with serial numbers come back, you can scan which ones in Warehouse > Inbound, in the windows to receive a parcel under Returns to sender and to book a customer return to a stock item, field Serial numbers (optional). It never stops a return. Exactly the scanned serial numbers get the new status (back in stock, returned or scrapped, depending on the grade). A serial number that was not shipped with this order is refused and named at the field, and so are more serial numbers than returned units. Without a scan, QrX updates serial numbers of that order line without checking which physical unit came back.

Open the stock item, go to the Lots and expiry tab and click the action Recall list: orders that shipped this lot on the row of the lot. The list shows every order that shipped units of this lot, the newest shipment first, with the units and the first and last shipping date. An order whose units came back later stays on the list. Is the lot sold out? Switch on Show sold-out lots above the Lots table (at most the newest 200 sold-out lots). CSV downloads the recall list as a file, for example to write to the customers of those orders.

Use Trace a serial number in Warehouse > History. The result shows the order the unit was shipped with.

Open the Serial numbers tab of the item and search the serial number. Blocked: unblock it when the unit is fine. Reserved for another order that is no longer packed: use Release. Shipped: the unit was already sent with another order, so check the unit in your hand.

Yes. Switch on Show sold-out lots on the Lots and expiry tab, open the recall list of the lot and download it as CSV.

No. The unit left without a scan, so QrX does not know which serial number it had. Check the order, then acknowledge the item in the report to reset its counter. To prevent it, pack items with serial numbers at the pack station.

Contact QrX support directly when the Tracking choice does not offer Serial although your plan includes it, when a serial number shows a status that does not match what happened, or when a recall list misses an order that shipped the lot. Mention the item SKU, the serial number or lot code, and the order number.
