Simply go to setup, company properties, logo tab and add your logo.
When you call up any SIN or PIN that you have created you have the option for statements and letters at the base of the page. It will automatcially pick up your logo.
With VT Transaction+ it's only meant for basic reporting rather than full accounts.
With VT accounts I've never used a logo although I have seen some accounts produced in VT accounts (not VT Transaction+) that do have a company logo so it must be possible. I suspect by amending the templates although don't quote me on that. When I get five mins I'll have to have a play with that to see how it's done (but for now thats waaaaayyyy down the to do list).
On a seperate note if you do go with a logo you may wish to opt for grey scale logo as coloured inks can end up being seriously expensive when you are doing quite a bit of printing.
HTH,
Shaun.
