QB Online just isn't a fully-featured program.  I cannot think of any benefits of QB Online.  If you are accustomed to power-using QB desktop, like I am, you cannot do what you want with Online.  I stuck it out until the end of our fiscal year and converted everything back to Desktop.  Now I once again have control of my company's accounting.  

For 8 months, I printed A/P checks 3-up, and also pasted pictures of my payroll checks into PowerPoint in 3-up format for printing, then ran them through the printer one more time, printing a second document onto them - the second document had nothing but 3 pictures of my signature, positioned properly on the sheet.

Just go back to Desktop.
