I just signed up for Shopvox but I'm still in the stages of setting it all up. I don't know the difference between signvox and shopvox but after a demo of shopvox, I believe it's a very powerful program and will help us in great measures. The only thing I can say is that I am about 15 hours in with setup and probably have another 40 hours to go before I can go live. That may just be becuase we offer so many services such as printing, wide format, screenprinting, embroidery, etc.
