Serial number and batch tracking are where items are tracked by either a serial number or as a batch. Serial numbers are (or should be) unique to the product, so a phone for a specific brand will have a unique serial number within that brand. Thus the quantity of a specific serial number that can be purchased or sold is one.
Batch (or lot) numbers can come in any quantity, and you can sell up to the maximum number items that you have in that one batch. For example, if you purchase 1000 packets of a drug, and 400 are from batch 1 and 600 are from batch 2, you can't (or shouldn't) resell 800 packets from batch 1 (instead it would be a maximum of 400 packets from batch 1, with the balance from batch 2).
For convenience, items that require a serial or batch number will be referred to as Serialised Items.
Notes on serialised items:
- Serial or batch numbers are allocated when you purchase/manufacture an item, or otherwise bring it into stock.
- When you sell serialised items, you must specify the serial/batch number at the time of sale.
- Serialised items cannot be autobuilt, and should not be components of another autobuilt item. MoneyWorks will ignore autobuilds that contain serialised items, so autobuilt item will just go into negative stock.
- A serialised item will have the same average unit value across all serial/batches (just like locations).
