Lot tracking

Lot tracking groups units of an item into batches identified by a lot number, so you always know which batch a given quantity came from.

Turn on lot tracking

1. Open the item under Inventory → Items.
2. Enable Lot tracking on the item.
3. Save. From now on, every receipt and issue for this item records a lot.

Turn on lot tracking before you build up stock. Switching it on for an item that already has on-hand quantity leaves that existing stock without a lot.

Assign lots when stock arrives

When you receive a lot-tracked item — from a purchase order, a work order, or a manual adjustment — Fiddle asks for the lot number. Enter the supplier’s batch number, or let Fiddle generate one. You can also record a manufacture date and an expiry date per lot.

Pick from a lot when stock leaves

Whenever lot-tracked stock leaves — a sales order, a transfer, or a work order component — you choose which lot to draw from. On-hand and available figures are tracked per lot as well as per item.

Field	Meaning
Lot number	The batch identifier
On hand	Quantity remaining in that lot
Expiry date	When the lot should no longer be used

Trace a lot

The lot history shows every receipt, issue, and transfer for a batch — essential for recalls and quality holds.

Next steps

For perishable stock, set up expiry dates and FEFO/FIFO so the right lots are used first.
