We sell services which are tied to a product, on the basis of a price per month. Sometimes on a quote this is an amount for more than one month, e.g. quarterly / annually.
So we would like to have the following columns:
Qty - exists currently - refers to the number of products
Price - exists currently - but we need the ability to specify this as Price / month
No of months (or a more generic term which is obviously not the same as Qty)
Total - which is Qty x Price / mth x No of mths
