What is the Customer Portal?
You are probably referring to our Customer Area at www.CleaningDesign.com We used to refer to this as the 'portal' as it is set up like the Communication Portals we create for cleaning companies. With our upgrade to Green Servers in October 2009 we upgraded our Portal to a full blow Customer Area that holds all of our Website Design, Logo Design, and Graphic Design Workrooms, offers social and community features, blogs and more.
Should I list my customers on my website?
That is entirely up to you.
Smaller companies don't always do these because of the competition at that level of the game.
Larger corporate services oftentimes showcase a larger reference account or two.
In either case you can always have photos without additional information.
