Hi there,
We have recently changed from Periodic Inventory to Perpetual Inventory. It all seems to be working well as far as tracking inventory items, however, I can't get the accounts correct anymore. In each Item in Inventory, we have:
"I Buy" - allocated to a COGS account for a group of items (eg. 5-1100 - Purchases - Item X)
"I Sell" - allocated to a Sales account for the same group of items (eg. 4-1100 - Sales - Item X)
"I Inventory" - allocated to the Balance Sheet Inventory account.
With the Periodic Inventory system, we'd do monthly stocktakes and adjust the values using Closing Stock in the P&L (eg. 5-5000) and the Balance Sheet Inventory account, which would be equal.
With the Perpetual system, each time there is a sale, the sale is recorded against 4-1100 - Sales - Item X, and it does another entry:
Debit Purchases - Item X (cost)
Credit Inventory - Balance Sheet (cost)
So the Inventory in the Balance Sheet reflects the actual inventory value, but the Closing Stock account isn't being adjusted at all. I now have a difference between Closing Stock in the P&L (5-5000) and the Balance Sheet Inventory account equal to the cost of any product sold and/or purchased.
If I had "I Buy" for each item allocated to Closing Stock (5-5000) rather than for a specific group of items (5-1100 - Purchases - Item X) it might work, but then we wouldn't have the COGS Purchases split we're after...
Any ideas?
