Anyone have good invoicing solutions?  For a variety of reasons, we don't have all the info we need to invoice in NetSuite, so this tool would need to be able to point at a non-NS DB and bill off of that info.  Bonus points if it has a NS integration, but that's not even necessary technically.  No need for subscription billing or rev rec. Built-in installment billing and collections are nice-to-haves, but not required.
I got RadiusOne and Invoiced off of 
Suiteapp.com.  Anyone have experience with those and/or have other suggestions?
