We also have an addon that will not only track cost and show margin (on order items and on order total) but can also be used to import cost and to calculate all pricing based on cost.
Product info: EZ Cost Basis addon
Product documentation: EZ Cost Basis PDF

Note that this product was designed around "cost based pricing" but you can easily simply not do it's custom imports to set prices based on cost. Instead just include a field called 'Cost' into your normal import CSV. You'll then get the cost/margin per product and cost/marging totals for orders (Admin invoices only).
As always, we have a 100% satisfaction guarantee. So if you're not completely satisfied and we can't address your concerns, we will happily refund your purchase amount.
