This feature has been requested for over 5 years now.  You continue to add advertisements and money generating services, but I pay almost $1000/year for this software and you won't add BASIC contractor features that clealry has hundreds of people asking for it.

Stop running commercials about how QBO is designed for contractors when you clearly don't listen to your customers or have any clue/desire to serve the contracting community.  So over QBO, can't find a replacement soon enough.
