For Secumailer , a specialist in secure email, I provided intensive telephone sales training via an online virtual connection. In cybersecurity, every word counts. As the best sales trainer in the Netherlands , I know that you must take control on the phone within three seconds, otherwise you will lose the prospect.
During these sessions, we drilled the 12 sales techniques for use over the phone. We utilized the 11 scientific topics of influence to build authority through the receiver. No hot air, but razor-sharp questioning techniques and Logic Selling (Spin Selling). Sales is a science , and on the phone, that science is even more precise: you must hear what is not being said and act on it immediately.
The result for Secumailer is a team that makes phone calls with more discipline and self-confidence. By taking my sales training , their telephone acquisition and follow-up are no longer a matter of chance, but a predictable system for growth and margin repair.
Expertise in sales psychology and results-oriented methodology.
Sales professionals trained to a measurably higher level.
Helping organizations achieve structural revenue growth and returns.
