Hey there, @Laura Harkness.
With the Add/Edit Multiple List Entries feature in QuickBooks Desktop, you can modify multiple items on a list all at once.
Here’s how:
- Go to the List menu.
- Choose Add/Edit Multiple List Entries.
- Select Inventory under the List.
- Update the amount under the Cost section.
- Click Save Changes.
You can also enter your inventory data into an Excel spreadsheet, then copy and paste it into the cost column.
For additional information about changing multiple items in QBDT, please refer to this article: Import or export MS Excel files.
I’ll be here anytime you need help. Wishing you all the best!
