How hard would it be to export a Quickbooks file to hand over to the accountant (assuming read-only case)? Sort of like Google docs exporting to docx.

My accountant and bookkeepers go in and edit entries and accounts. So there is no read-only case where my CPA is concerned.

QuickBooks desktop isn't really a supported platform anymore. Most people have migrated to QuickBooks Online and their accountant has a login to their account.

I think this is the major reason. Accountants would usually label themselves as "Quickbooks/Xero certified partner" as a selling point.

I had Wave...it was free. Accountant was OK w/ it then asked me to change to Quickbooks after 2 years. I understand Quickbooks has a lot of functionality that's great for CPAs, but none that I need. I'm the one who spends hours a week in it.

The only reason why I said yes is because of the many CPAs I've interviewed they were the best (they probably aren't the best, just a lot of them are terrible).
