Book excerpt: Upselling—the art of suggesting upgrades to purchase—can help you grow your average order value (AOV) with relatively little marketing effort. These customers are already interested in your brand and products. Your job is to show them relevant upgrades at the right time and place. Done well, upselling can build upon your relationships as well as increase your revenue. But done poorly, you can come across as an aggressive car salesperson. Take the "Selling" Out Of "Upselling". In this book, you’ll learn upselling techniques as well as why cross-selling is so important.
