I would like to be able to set a per hour rate for each of my clients - I, like most service providers have no need for products but offer all my services on an hourly basis. A field in each client to establish their hourly rate and being able to bill them accordingly would be great as clients pay different rates for different reasons (i.e for us schools and charities have a discount as do local businesses) - at the moment I have to use the discount option per invoice and have to somehow remember what rate each client pays and then have to work out the percentage of discount to get to this rate - tedious to the extreme!
