# Inventory value vs FIFO

Sapera's inventory value compared with a true per-layer FIFO value — and why they differ.

The **Lagerværdi vs FIFO** (Inventory value vs FIFO) tab compares the inventory value in Sapera (quantity × cost price) with a true FIFO value, where each remainder of a purchase is valued at its own cost price. The page shows where the two differ, and why. It is a tool for finding errors in setup and stock handling.

## What the page shows

-   Cards with **Lagerværdi i alt** (total inventory value), **FIFO-værdi i alt** (total FIFO value), **Diff (bogført − FIFO)** (difference, booked − FIFO) and **Diff %**.
    
-   How much of the difference is due to: **Heraf negativt lager** (negative stock), **Heraf lokations-ubalance** (location imbalance), **Heraf serievare** (serial-number items) and **Heraf kostprisforskel** (cost price difference).
    
-   A table per department, location, item, variant and serial-number item with quantity, inventory value, FIFO value, difference, status and an **Åbn** (open) link that opens the item in Shop Manager.
    

## How to use it

-   Search with **Varenr (søg)** (item no.) or **Serienr (søg)** (serial no.), and narrow down with **Kategori** (category) and **Status**.
    
-   Use **Diff over (kr)** (difference over, DKK) to see only rows with a difference above e.g. DKK 100.
    
-   Right-click an item and choose **Drill through** → **FIFO-detalje (bilag)** (FIFO detail) to see the movements in FIFO order, or → **Lagerbilag** (Inventory vouchers) for all stock movements.
    
-   Use **Diff pr. dag** (Difference per day) to find out when a difference arose.
    

## Good to know

-   **Negativt lager** (negative stock): the item was sold before it was in stock (short across all locations).
    
-   **Lokations-ubalance** (location imbalance): negative stock at one location, covered by stock at another.
    
-   **Serievare** (serial-number items): items with serial numbers, where stock has been moved from the base item to serial-number items.
    
-   **Kostprisforskel** (cost price difference): the item was sold at a different cost price than the FIFO layer's.
    
-   Only rows with a difference are shown. The cards always show the total, regardless of **Diff over (kr)**.
