I purchased Express Accts and tech support 2 days ago and have discovered that the Inventory balance is NOT automatically adjusted into Cost of Goods Sold when products are sold via an invoice. I have entered all product items into the program and have filled out the sell and cost prices for each item. I have noticed several other threads that complain about the same thing so I'm not wasting any more time experimenting myself with this. Any decent accounting package should do this, even the cheap ones. Before I request a refund through Paypal I thought I would post this and see if "tech support" responds in the next 12 hours. Thanks much!
