MAKE sure you know your unique selling point, be it yourself as an individual, or your company.
Really understand it and make sure you tell the world about it in any proposition. People need to know the benefits so make sure you explain, clearly and concisely, just what it is that makes you, or your company, unique.
Finally, make it simple and easy to understand because that could mean the difference between a sale or not regardless of the product’s quality.
That way your sales will catch fire, and not be in danger of going up in smoke.
