Quote follow‐up is one of the communication activities that generates the most revenue with the least amount of work. Consider the vast number of quotes that you send out, which are never, or only lightly, followed up upon. A three‐communication follow‐up process includes: email/email/ email, or email/email/call. Many clients have sizable teams that take phone calls for new estimates all day long. Some companies call this group customer service, and others call it inside sales. If you send them a price and they never hear from you again, the odds are they've given their business to somebody else, who did follow up. Two emails and a phone call. That should get you to a yes or a no. And if the customer still doesn't reply, he's simply being rude and unprofessional. He asked you for a quote, you delivered, and he refused to give you an answer.
