Billings.

Are you self employed in a field that requires hourly billing or flat rate service billing? Sometimes I am–not very often but sometimes–and I have to tell you, there is no better app that I’ve found to help me do this than Billings from Marketcircle. Seriously, this app will save you a lot of time and make your life so much easier. It’ll help you with your estimates, your time spent per task, keeps track of your paid and unpaid invoices and even let’s you design your own invoices (this is a little wonky but if you’ve ever used Filemaker you won’t have a problem with it). Well worth the $60.
