You need to have a softrak partner come on site and show you how to use Adagio Inventory.

Under Edit | Control Accounts, make sure you have an account set that specifies Average Costing. Assign your items to this account set to use Average Costing. Recent cost will be updated when you receive goods into inventory, although you can enter an amount when you add a new inventory item.

"Additional costs" are costs associated with your inventory that might not be paid to the supplier. Shipping costs are the most common "Additional costs", but there may also be brokerage and other landing costs. Additional costs may be prorated over inventory when the goods are received.

"Is the unit cost included in all costs?"

Sorry, I don't understand the question.

To get your inventory value into shape, you need to do a physical inventory. Print out an inventory valuation report, and enter adjustments to the quantities on hands and/or costs to bring your inventory costs to what you know them to be.

Also, when I set up the new item and do a purchase order I don't need to enter? Please, show me the step by step to enter the new item and purchase order.

Both Purchase Order modules are developed independantly on Adagio. You need to talk to your Softrak Partner about the specifics of using the Purchase Order module you have. There is a session on Purchase Orders for Adagio tomorrow as part of the ACCPAC Users Group. You should register (it's free) here.

Your Softrak Business Partner will show you the best way to implement Inventory Control, Purchase Orders and OrderEntry, and how they integrate together. As this is business consulting, the assistance is rarely free.
