Do you think that you can get a better deal if you buy a new product from a sales agency? As a sales person, you must know that there’s a lot of potential buyers who are looking to change their sales processes to get something you can now get. If you are already a salesperson, you’ll probably be more likely to give your initial acceptance before you go sell someone else’s products.
What I love about sales is that they are a “low hanging fruit” scenario. That is, if you’ve got that great product, and you work for a company that’s selling it to other companies, you’re probably already a good sales person. I’m not saying that you can’t be a good sales person, just that you have to be an expert at it.
