I have been looking Quotewerks will do the markups on an estimate and uploads into QBO. Unfortunately it is $26/month and you also have to buy the application, starting $300. It is not an app even though it says so on QBOA. QBOA also says it is $20/ month. It does lots of other things that I simply do not need for that price. I am still searching and may be looking for a different accounting package all together if QBO cannot add this feature.
