What does it mean?
When a sales rep has more than one type of product to offer consumers that could be beneficial, and s/he successfully sells a consumer more than one item either at the time of purchase or later on. An example is when Apple sells you an iPhone and then successfully sells you an Apple iPhone case or a pair of Apple headphones. In this case, a sales rep identifies a need the customer has, and fulfills that need by recommending an additional product. (Cross-selling differs from up-selling; see up-selling.)
