Thanks, however you haven't read the question. I am up to speed with how to place a logo, manipulate it in QB. 

What I want to know is the best size pixel by pixel the image should be. Reason being that if designed to the wrong size the logo will be unusable on an invoice; either blurred and pixelated or way too detailed. 

What is the best width and height of "canvas size" should the designer I'm employing use when they are creating my new logo.
