How do you stop sales calls at your business? -

There is only one way... You either hire a receptionist (phone person) to screen them, do it yourself (which did nothing for you) or deal with it. If I had $1 for every time a merchant called my business to handle my credit cards alone, I would have more money then Microsoft.

Is that really a good idea?I ve improved my business on three occasions of answering sales calls

You put a sign up near the door that says All sale people seen by appointment only.
