Why it happens
A sale never checks stock, so the till never blocks a sale. A minus number usually means the opening count was wrong, or the item was sold before anyone counted or restocked it. Anything at 0 or below reads Out.
How to fix it
- 1
Open Inventory and find the item.
- 2
Tap Adjust stock, pick the item, and add the amount that was missing.
- 3
Under Why?, choose Count correction (was too low) to add. Use Count correction (was too high) on the remove side to take away.
- 4
Tap Add stock. The history later shows Count fix.
- 5
Stock tracking needs a Pro plan. Staff need the owner to switch on Can adjust stock.
