I find it totally unacceptable to not be able to remove those logo and "watermark" on email from QBO, I mean we all pay for this software, It is not a freeware, I don't want my company mail to be a promotion tools for you guys.

Yes I can send the link or download the invoice and send it from my email, but the point of using QBO is to make everything in one place ! 

We should charge you a commission for each invoice sent since it is a promotion tools for you.
