I hand-write amendments, because it's too much trouble un-checking all the people you will need to issue 1099's to for next year.

Just one of the many flaws of QBO.

--But the real reason I won't recommend it to clients is because there's no way to back up your file for your work-papers.  Printing the GL, and trying to export payroll reports is a royal pain. So I've started describing QBO as "predatory". They are so desperate to not let you leave or convert to desktop, they put your accountant in a very awkward situation with work-papers (items including payroll reports by employee probably should be backed up for ethical reasons).
