I'd be happy to address your follow-up question about inventory shrinkage, Ccalabrese.
If you're referring to the Account Type and Detail Type found when creating a new account, that is normal. If you're not sure which account and detail to use, I recommend reaching out to your accountant. This is to make sure everything is accurate.
Regarding your question about the screenshot for Inventory Adjustment, the answer is yes. From there you can manually change the New QTY to zero.
Here’s how to edit your product and service item:
- Go to the Gear icon.
- Select Products and services.
- Locate the product you want to adjust and click the Quantity link under the Quantity on hand column.
- Enter zero under the New QTY column of the item then click Save and close.
