FIFO inventory
Oldest stock out first, and every lot accounted for
Every purchase or opening balance creates a lot with its own cost. Sales consume the oldest lot first, a single line can draw from more than one lot, and every movement traces back to the document that caused it.

The situation
What gets in the way today
FIFO in name only
The software averages cost, so the oldest stock is never actually tracked.
Batches can't be traced
When a buyer asks which batch they received, the answer is in nobody's file.
Margins hide what changed
Purchase costs move every month, and an average conceals it.
How AVS fits
Lots you can follow from receipt to sale
Costed lots
Every receipt becomes a costed lot
- Each bill line creates a lot with its own cost and barcode
- Lot IDs carry the vendor code and a sequence
- Opening stock is entered as lots too, so FIFO works from day one

FIFO sales
Oldest lot first, across as many lots as a line needs
- Sales drain lots first in, first out, across more than one lot per line
- The lot page shows the full purchase-and-sale timeline
- Every invoice that consumed a lot is one click away
