How do I undo or reverse a sale?
To undo a sale, open the sold item, tap the ⋮ (three dots) menu in the bottom bar, and select Mark as Unsold. The item returns to Listed status.
Step-by-Step

Find the item in your Sold items (use the status filter)
Tap the item to open its details
Tap the ⋮ (three dots) menu in the bottom bar
Select Mark as Unsold
The item returns to Listed status, its Date Sold is cleared, and the sale is removed from your reports.
Good to Know
Undoing a sale also reverses the profit calculation and updates your reports
Use this for returns, canceled orders, or if you recorded a sale by mistake
Mark as Unsold only appears on items whose status is Sold
The item keeps its listing details (platform, price) after undoing
