delete opening inventory entry

I understand that you want to delete an item, juliaah33.

The best option I can suggest is to adjust it to zero out the quantity on hand. You can follow these steps:

1. Go to the + New button and select Inventory Qty Adjustment.
2. Enter the Adjustment Date and the Inventory adjustment account.
3. Select the Product and enter the new quantity.
4. Click Save and close.

Once done, you can review  your Asset and Opening Balance Equity account to see the adjustments.

I'll be here if you need more help. Have a great day!

Thank you for posting here in the Community, Tim.

Let's modify the starting date of the item created so you can use it when processing estimates or purchase order (PO).

Inventory items that were added fall before the date you're trying to create a transaction can't be used. To get this fixed, please follow the steps below:

1. Click Sales from the left menu, then select Products and Services.
2. Find the created item and click Edit under the Action column.
3. Under Quantity on Hand, click Starting Value. A message will appear warning not to change this value, select Got it!
4. Change the As of date field to the correct date. This item can only be added on transactions that are dated on or after this date.
