As
you can see the cost is displayed and you can enter it here. This
is true with Non-Inventory parts as well as Inventory parts as
long as the checkmark appears next to "This item is used
in assemblies or is purchased for a specific customer job".
Average Cost – The cost for this option is taken from
the Inventory Detail valuation report. This is the average cost of
the item at the time the customer was invoiced. This option
only applied to Inventory items as they only would have a
Inventory Detail valuation report.
If this option is selected and the item is not found on the
valuation report CommTrack™ will use the Purchase Cost from the
item.
SO PO INV – This option is selected if you create PO’s
and Invoices from a Sales Order. When you have a Sales Order Open
and look to the top right hand side you see this drop down.

When you create a PO from a Sales Order it puts the Sales Order
number in the memo field of PO’s created this way.

This is how CommTrack gets the costs related to the items on
that PO. For this to work properly you need to invoice from the
Sales order the same way you create a PO.
If CommTrack does not find a match on an item it will look to
for an average cost (only Inventory items). If no cost is found it
will then use the purchase cost of the item.
Bill Invoice: This option allows you to get the
cost directly from a bill. The only requirement is that you use
the Bill number is the invoice number.
If CommTrack does not find a match on an item it will look to
for an average cost (only Inventory items). If no cost is found it
will then use the purchase cost of the item.
Job Costing: If you use JOBs you get get the
exact costs you can get the exact costs in using our custom field
called "STD COST". Just run your Job Profitability
report and take the total cost and enter it on one of the line
items on your invoice.
