So far I have been very impressed.
I have tested:
ClearBooks
KashFlow
FreeAgent
QuickBooks Online
Xero
Freshbooks
Kashoo,
etc. … but ClearBooks seems the best fit so far for a freelance translator.
We are also currently discussing it and the various other options over on the largest online platform for translators @ http://www.proz.com/forum/software_applications/312953-looking_for_excel_spreadsheet_for_invoicing_payments_etc_ie_diy_to3000_clone-page2.html
Without wanting to bore you with too many details, in the translation community there is a program called "TO3000", which many people use for their accounting/project management, but most of us hate. The program gets updated at a glacial pace, and is hideous. It is desktop-based and has no connection whatsoever with bank feeds, exchange rates, etc. Anyway, if I decide to use ClearBooks, and mention it here and there over at Proz.com, I wouldn't be surprised if you saw quite a few translators heading your way.
There are actually quite a few new translation project management/invoicing programs/solutions popping up here and there, most of them web-based, but as far as I know none of them have automatic bank feeds, and all kinds of other things that ClearBooks has. In actually keeping track of the latest ones and will copy paste my list here (in case it is of interest to you):
