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.
The four numbers
| Number | What it is |
|---|---|
| On hand | The physical units actually sitting in a location. |
| Committed | Units already reserved for unfulfilled customer orders — they're spoken for and will ship out. |
| Available | On hand − committed. The units genuinely free to sell. |
| Incoming | Units 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.
