I need a Average Days to pay report.  We have thousands of invoices with a single customer, making this excel work around unmanageable.  I pay substantially more for QBO than I ever did for QB desktop.  I do not understand this lack of total basic reporting at the highest level of subscription.  It's been 2 years since this was first posted and there's nothing better than pay someone else to do it for you or make an elaborate spreadsheet outside of the software system you use to track invoices?
