Selling security guard services is admittedly not the sexiest of jobs, but with the right attitude and motivation you can do well both professionally and financially. In order to be great at security guard sales, or sales in general, it requires extensive reading and even more practice. One of the first books that I read and refer back to fairly regularly is The 25 Most Common Sales Mistakes and How to Avoid Them by Stephan Schiffman. Stephan is a Certified Management Consultant who has trained and consulted with corporations such as IBM, Motorola, and Cigna. He has trained over 500,000 professionals across 9,000+ companies. Of the 25 most common mistakes outlined in his book, there are 10 that are essential to anyone involved in security guard sales. I have taken the liberty of summarizing those 10 below.
Mastering Security Guard Sales
Security guard service is one of the most competitive industries that exists (if it isn’t it, sure does feel like it) and losing a sale can be the result of being a pen
