This morning I dropped by the dry cleaners to pick up my clothing. As I handed her the ticket, she gave me my dry cleaning and then asked me a question. "Do you send out your husbands shirts?" "No," I told her. "He's retired. He doesn't wear shirts." She smiled as she explained in her accented English, "Oh I was just trying to..." I supplied the word she was searching for. "Upsell?" "Yes," she said. "Well my husband only wears golf shirts. But very good marketing. If we ever have a wedding to go to I'll bring in his shirt." We both had a good laugh.
But the laugh is really on business owners who don't see an opportunity and follow up. This woman realized that a presentation doesn't end when there is an exchange of money. The presentation lives on as you continue the dialog.
Even the post office now asks if you want stamps, mailers, or other supplies. The way you approach a customer is a presentation-from the greeting and smile, to the conversational interaction, to the thank you, to the upsell. Just like any presentation there is a beginning, middle and an end.
Unfortunately, not everybody gets beyond the first presentation.
