Based on their web site information,
ProOnGo discusses integration with Quickbooks Online, not the PC-based versions. Is it the case Quickbooks Pro is not supported? Also, ProOnGo doesn't mention any pricing, so I worry how their business model works (visions of a Web 1.0 experience). Their update list makes it appear this is a product that is very actively supported. See

Exgis seems to offer Quickbooks integration only with their multi-user $10/user/month product (cost effective if it works and the support is adequate), but they capture mileage, expenses, and time separately, which sounds very convenient. See

I'm starting to experiment with Acire's
ReportAway because it's cheap, and I only need to capture cash expenses. It has expense photo integration, but without ProOnGo's character recognition features, although that is a promised feature from partner company. It does integrate with Quickbooks Pro, but I haven't messed with that stage yet. It is $8.99 for a copy, but it appears to be free if you sign up for a DocSnaps account for image capture at $7.99/month for an individual user (free 30 day trial). Acire and DocSnaps appear to be separate business. A new version of ReportAway has been recently released.
