Movements & WAC valuation

Every quantity change is a traced, dated stock movement. SynkriaOps values these movements at the weighted average cost (WAC) and updates the total value of your stock in real time.

Movement types

Type	Effect on quantity	Typical origin
Inbound	+	Order receipt, supplier invoice
Outbound	−	Sale, consumption, breakage
Adjustment	±	Manual correction of an observed gap
Inventory	±	Gap from a counting campaign

Each movement records the quantity before and after, the valuation amount, and — when posted — the link to the associated document or entry.

The weighted average cost (WAC)

The WAC is the average unit value of your stock. It is recomputed on every inbound movement, by weighting the old stock and the new arrival.

A concrete example

You have 10 bags in stock at 5,000 XAF each (value: 50,000 XAF). You receive 10 bags at 6,000 XAF (value: 60,000 XAF).

New WAC = (50,000 + 60,000) ÷ 20 = 5,500 XAF each.

Subsequent outbound movements are valued at 5,500 XAF until the next inbound.

This method, compliant with SYSCOHADA, smooths purchase-price variations and gives a realistic stock value on the balance sheet.

Adjusting stock manually

When you observe a gap outside an inventory campaign (breakage, loss, gift):

1. Open the product page → Adjust action.

2. Enter the store, the new quantity (or the gap) and a reason.

3. Validate. SynkriaOps creates a timestamped adjustment movement and recomputes the valuation.

An adjustment is not trivial

An adjustment changes the value of your stock — so, if posted, your class 3 accounts. Reserve it for justified corrections and always enter a clear reason for traceability.

Total valuation

The Stock dashboard permanently shows:

• the total WAC value of your stock, across all stores;
• the breakdown per store;
• dormant products (no recent movement) and stockouts.

This value must stay consistent with the balance of your stock accounts on the balance sheet: that’s the control point proving your physical stock and your accounting tell the same story.
