Some of the costs related to your business will vary, depending
on the number of each product that you sell. These should be
entered here, as Unit Costs.
We'll calculate your total unit cost per sale at the bottom of the
table. Remember, if your price doesn't even cover your unit
cost then you're in trouble.
If this product really doesn't have any unit-costs, click
the button in the purple bar at the bottom of the table
so we know not to remind you about it. You can still add some
later if you realise you'd missed something.
