Understanding stock levels and availability

Fiddle tracks several quantities for every item at every location. Knowing what each one means prevents most “my numbers look wrong” confusion.

The four key numbers

Quantity	Meaning
On hand	Physically in your possession right now
Committed	On hand currently assigned to sales, fulfillment, or work-order demand
Incoming	On open purchase orders, not yet received
Uncommitted	On hand minus committed
Short	Demand not covered by committed on-hand or incoming supply

The formula that matters most:

Uncommitted = On hand − Committed

Why uncommitted can differ from on hand

If you have 100 units on hand and 30 are committed to current demand, your uncommitted quantity is 70. Commitments guide purchasing and production; they do not prevent authorized inventory operations.

Open Inventory → Commitments to see which orders are covered and where the stock is.

Per-location vs. total

Each location has its own on-hand and committed figures. The item’s total is the sum across locations. If you run multiple warehouses, always confirm you’re looking at the right location before adjusting stock.

When numbers look wrong

Most discrepancies come from one of these:

• A sales or work order currently receiving committed coverage.
• A purchase order received into the wrong location.
• A pending transfer between locations.

The inventory activity log shows every movement for an item — start there to trace any unexpected change.
