I just purchased Billings and am just getting started. I do the billing for my husband's law firm and it's hard to find a mac billing program, but I'm looking at questions and issues and thinking that this is not going to work out for me. I have at least 40-50 invoices a month that have no activity on them and still need to go out each month. Plus, I'm trying to figure out how to start with an outstanding balance. Any ideas on any other programs or anyone use this for legal billing?
