Is there any way to have a google map on the QB homepage that I can ""click"" on and pull up co-ordinates to create a new client & Job site? also have the map display jobs?

That actually works very well. So what I have done is:  
1) Put the address details in a multi text box and
2) then put the "location" details in GPS format in line 1&2 as you said.

Is there any way to incorporate a "clickable" google maps layer within QB?
