Hello FournierFinishing,
Thanks for reaching out to us here. I understand how advertisements can impact your work. QuickBooks Online provides a variety of ads that create awareness of features offered. At this time there isn't a way to stop the ads other than selecting No thanks, or simply hitting the X (close) option. Please don't hesitate to submit your concerns to our Development Team if you would like to see the option to turn this off moving forward.
Feel free to reach back out with any other questions. We'd be happy to help!
