QuickBooks 2015 upgrade download
The 2015 version includes a number of improvements for the outside accountant, but not so many for end user. If you are currently using QuickBooks 2017 or 2014, I'd wait to upgrade after we see what will be introduced this fall for the 2016 version. If you are using 2012 or earlier, however, I'd strongly suggest you consider upgrading to QuickBooks 2015 version. The user interfaces are better. You can copy/paste line items, scale reports, record bounced checks much easier and there are better overview snapshots.
QuickBooks also offers an online version, QBO (QuickBooks Online). It is a very different program from the desktop version, but does give you the flexibility of a cloud-based program. For a church or nonprofit, I'd recommend the desktop version, as you can purchase the 2015 desktop version of QuickBooks Nonprofit Premier for only $45 from
