We're big fans of QB's Enterprise and need all it's deep features, but it's not user friendly in the field and our sales reps are required to return to the office to write and send estimates. Yes, we host and they do have the ability to access the file everywhere but its interface is not mobile friendly.

I'm thinking of implementing QB's online solely to give my sales people the ability to write and send estimates in the field from their phone or tablet. That's it, estimates only. We will continue to use Enterprise for everything else. 

Anyone have experience using both softwares for a single company?
