Someone else will really need to help you with Jobber, but I don't think you really want to use QBs only for the Banking. That will basically kill all the reporting and tracking your CPA will want.
As I understand Jobber it is just to sync with QBs Online and not meant as a stand along program. All the info needs to come back into QBs where some of it is correctly entered and some is left to be modified to be correctly entered into QBs. For companies with multiple people entering remotely, it sounds like it might be a good fit. But unless you're big enough to need it and have a full time person managing the syncs, you might consider why you're using it. Is it the right fit for your company or bells'n whistles.
