Matthew is author of "Get A Grip", a book that has sold ten of thousands of copies and has 166 reviews on Amazon.
In Creating Business Growth Matthew has a chapter entitled How to have more frequent, more effective sales conversations.
One tip he gives is that you need to identify the people that want to buy what you have. Now that may sound basic but so often I see people trying to sell a product or service that no one wants. It is a bit like on Dragon's Den where the people pitching for investment have a solution to a problem that doesn't exist.
Then Matthew goes on to explain a whole series of things about sales that can really boost sales .. but only if you read his chapter and apply them to your business.
