Does anyone have any experience with the invoicing software "Billings"? I run my own freelance business and have been using "MacFreelance" for the past 5 years or so. It's pretty basic, and I only really use it to submit quotes, create invoices and track clients. It does offer me the ability to track expenses, I just didn't take advantage of that when I started and then got stuck in my ways. Anyways, said bookkeeping has always been handled on my older Mac and I've recently upgraded my whole office. The only downside is MacFreelance doesn't appear to run very well in 10.8, so I'm checking out what the alternatives are so that I can switch my bookkeeping over to the new machine and finally put the old gal to rest. Any feedback on Billings, or alternatives would be greatly appreciated. I'm looking for a standalone application here as well, not a monthly service like Fresh Books, etc. Thanks!
