Explanation:

These sales representatives proposition customers at the very beginning of the selling process to deduce just how much the market is interested in the product(s) offered by the business which they represent. This propositioning can happen over the phone or in person and the canvassing for potential customers could be business to business or business to consumer. This stage is defined as the prospecting stage as the business seeks to identify the allure that its product has in its intended market.
