Can you please help me to resolve profit and loss report errors that is cost of sales is not matching actual purchase bill entered

I will share possible scenarios for why your profit and loss accounts are unbalanced, Accounts.

One scenario is that you've purchased the item at a new price from your vendor. The other scenario is that the item is in the inventory asset account, in which case the inventory won't show on the profit and loss statement but will show on the balance sheet.

The last possibility is that you've got a sale with no available stock and purchase the item at a later date. We can also consider checking the reporting period.

Also, I'd like to share this article to assist you in customizing your reports: Customise reports in QuickBooks Online.
