I have steps so Inventory Shrinkage will remove in your Profit and Loss report, @izumij-mandnllp-. Happy to share detailed steps to achieve your task.
I'd recommend using the Cash method to eliminate Inventory Shrinkage. Just remember that if you switch accounting methods, the accounts and balances in your reports may change.
Follow these instructions:
Go to the Reports menu, then open Profit and Loss.
Click the Customize button and pick the appropriate Report period.
In the Accounting Method, choose Cash.
Select Product/Services in the Rows/Columns drop-down.
In the Filter section, choose relevant data and hit Run report.
