Understandable that one product will not be all things to all people, but to criticize it because the developer does not respond to your suggestions or complaints or bug fixes does not necessarily make a product bad. Sure, this is not Microsoft or Apple, so we as users expect the developer to pay attention to us; but notice that this is essentially a one person show. There is an excellent on line discussion forum for the product that has helped me greatly with its use.

Having said that, if you are looking for software to track time and charges to multiple clients at varying rates, print invoices and have options for different summaries of your work, then iBiz does it at a reasonable price. Invoices can be customized, although not necessarily in a completely intuitive way (i.e., read the documentation, browse the support forum). Stability is important where finances are involved and I have found iBiz to be extremely reliable.
