There are many ways that you can engage your customer base about print during routine conversations. The easiest way is to simply ask:
“Do you guys like your current print vendor?”
I know it sounds dumb, but trust me: You’ll likely open up a little bit of pain to talk about.
From there, if it seems appropriate, you can just say that you have a preferred print vendor that would be happy to audit your print environment and give you a fresh look at your total print costs. At no cost.
