Adjusting stock quantity manually
An adjustment changes the quantity of an item and records the reason in your transaction history. Use it any time you need to change stock for a reason that isn't a sale, a purchase, or a transfer — most commonly: stock counts, breakage, waste, theft, samples given away, or correcting a mistake.
Adjustments are how you keep your audit trail clean. Editing the quantity field directly works too, but you lose the "why."
Who can do this
Both Admins and Members can adjust stock.
How to adjust a single item
Open Inventory from the sidebar.
Click the item you want to adjust.
Click Adjust stock.
Choose how to enter the change:
Set to — enter the new total quantity (e.g., after a stock count).
Add — enter how much to add (e.g., found extra in the back).
Remove — enter how much to remove (e.g., breakage, waste).
Add a note explaining why. This is optional but strongly recommended — it's what shows up in transaction history and audit logs.
Click Save.
The new quantity takes effect immediately. A transaction record is created with the source adjustment.
Adjusting many items at once
For stock counts or recurring waste tracking across many items, use bulk adjustment:
In the Inventory list, select multiple items using the checkboxes.
Click Bulk adjust in the action bar.
Enter the change type (set / add / remove) and the value for each item.
Add a shared note (e.g., Monthly stock count — March 2026).
Click Apply.
Good to know
Adjustments are tracked in transaction history
Every adjustment shows up in the item's transaction history with the previous quantity, new quantity, change amount, who made the change, and the note. Open any item's detail page and look at the History tab to see all adjustments and other movements (sales, transfers, POs).
Adjustments don't affect cost
An adjustment changes quantity, not cost price. If you need to change what you paid for an item, edit the item's Cost price field directly. See Editing or deleting an inventory item.
Negative quantities aren't allowed
Stash won't let you adjust below zero. If you try to remove more than you have, Stash will cap the result at 0.
When to use a transfer instead
If stock isn't lost — it's just at a different location — use a stock transfer instead of two adjustments. Transfers keep both shops' totals correct in one operation and create a linked record. See Creating a stock transfer between locations.
Common adjustment reasons (templates)

Data correction
Using consistent notes makes reports and audit reviews much easier later.
