"Everyone is a salesperson"
I hear this said at so many companies it's untrue. While I can understand the sentiment it's a very dangerous strategy to follow. Ambassador possibly, Representative maybe but salesperson NO!
Sales is a highly skilled, specialist discipline and becoming more and more so as we move forward. Despite this I am often amazed how few officially designated salespeople understand "how" to sell, and why they do the things they do.
To then encourage staff members that do not work in sales, have never had any sales training, do not understand how any sales process works, let alone one that is tailored to suit their business, and is very unlikely to understand what part they should play in that process is actually unfair on them.
If, however "everyone is a salesperson" is a mindset that you wish to instill in your business then give people the tools to work with.
A tailored "Sales for support staff" or "Sales for your Non-Sales people" course will help avoid both missed and lost opportunities, and you never know might help identify that sales superstar you have hidden in the admin department.
