Successful customer retention is the goal of every salesperson. "From Wild Boar to Truffle Pig" comprehensively addresses all essential aspects of selling, starting with elements from the personal sphere of the seller, including the signals they emit (appearance, gestures, facial expressions). The differences between a salesperson and a sales personality are highlighted, as well as the key rules of conversation that have been valid since ancient times. Persuasive, easy to understand, and filled with illustrative examples, the book provides convincing insights into all sales situations and their challenges (prices, discounts, objections, complaints, etc.). It also presents numerous ways to optimally deal with different types of buyers. Finally, the chapters on salary negotiations, career opportunities, and ineffective sales methods round out the work.
