Inventory: on hand, available & committed

Stockwik mirrors four inventory numbers from Shopify for every product. Knowing what each one means is the key to reading the rest of the app — especially the reorder suggestions, which are built on available stock, not on hand.

Note
Shopify is the source of truth for your stock. Stockwik shows these numbers exactly as Shopify reports them — it never invents or quietly changes them. (Stockwik only writes back to Shopify when you receive a purchase order, commit a count, or update a cost.)

The four numbers

NumberWhat it is
On handThe physical units actually sitting in a location.
CommittedUnits already reserved for unfulfilled customer orders — they're spoken for and will ship out.
AvailableOn hand − committed. The units genuinely free to sell.
IncomingUnits on open purchase orders, expected to arrive.

A quick example

You have 100 units on hand. Customers have placed orders for 20 of them that you haven't shipped yet, so those 20 are committed. That leaves 80 available — the real number you can still sell.

If you also have a purchase order in transit for 50 units, that 50 is your incoming stock.

Why "available" is what matters for planning

It's tempting to look at On hand and feel comfortable — but those committed units are already going out the door. Planning against On hand would make you reorder too late.

That's why every replenishment calculation in Stockwik — the reorder point, the order-up-to level, days of stock, and the suggested order quantity — uses available stock. It reflects what you can truly sell before you need more.

Tip
If a product looks healthy on On hand but shows up on your reorder list, check its committed quantity. A pile of unfulfilled orders can pull available below the reorder point even when the shelf still looks full.
