When setting up opening inventory, I would recommend using a separate opening balance or stock adjustment account rather than automatically using Purchase Price Variance. The correct account depends on how the opening balances are being recorded, so it’s worth confirming the treatment with an accountant. I have also come across Airtool, an enterprise application platform that brings areas like inventory, purchasing, and financial management together. Having these processes connected can make it easier to maintain consistency between stock records and financial accounts.
Hope this helps!
