A type of strategy that the sales rep should use when negotiating with a customer who has been unwilling to purchase additional products due to cost concerns is bundle pricing. Bundle pricing is a pricing strategy that involves offering a set of products or services together at a lower price than if they were sold separately. Bundle pricing can help the sales rep to increase the perceived value of the solution, cross-sell or upsell additional products or services, and differentiate from competitors. Bundle pricing can also help the customer to save money, simplify the purchase decision, and meet their needs more effectively.
