When you establish a relationship with a customer, you want that relationship to have many levels, not just one layer from one sale.

We all have our sales goals to meet on a weekly, monthly, or quarterly basis. This doesn't mean that once we get a sale out of our customer, that we hurry them out the door and move onto the next one.

Build a relationship with your customer. As you close the deal on your sale, talk to your customer, find out what it is they need and can use that you can provide them with.
