Currently, the option to arrange the list in the Chart of Accounts manually is unavailable in QuickBooks Online. We can only sort the list in ascending and descending order.

CPA's and Accountants desperately need this capability. We realize that you might think this keeps people from screwing things up if they aren't accounting savvy, but some of us are accounting professionals whose hands are tied by this inflexibility. Please reconsider and restore this functionality in the next update or, at the very least, provide an override for Accountants.
