Re: Can I add an entire year? I already have 2018 but want to add 2017. I just started doing the books for a small non profit with not much activity.
As a workaround, you can use Business Importer to import all the data needed. It supports wide variety of entities and has Free trial period, so you are able test the app and resolve your issue. The app has many useful features, which will definitely save you a pile of time spent on manual entry.
