Inventory adjustment. I'm confused with the terminology of inventory shrinkage. I want to adjust the inventory to add to an existing product, which account do I use?

Hi userpurchase,

Welcome to Community!  It's important that you're able to successfully make adjustments to your inventory and ensure they're directed to the appropriate account.  QuickBooks Online has a couple of options for adjusting your inventory.  Based on the description you've provided, it appears that you want to adjust an existing product.  This can be done manually directly from your list.  I'll show you how!

To locate the existing product, follow these steps:

1. Click on the Gear in the top right of your account

2. Select Products and Services

3. Locate the product and in the Action column hit Edit

4. The account information should already be applied

5. You can change the Quantity, Starting Value, Reorder Point and Sale Price

6. When you're done, hit Save and Close

For your reference, here's an article for Inventory Adjustments.

For additional assistance or any other questions you may have, please reach back out.  We'd love to help!
