Price objections are related to the customer's perception of the value of the solution and their ability or willingness to pay for it. Return on investment (ROI) is a measure of the value that the solution provides in relation to its cost. If the customer is concerned about ROI, it means they are not convinced that the solution is worth the price or that they can afford it. The sales representative should address this objection by demonstrating the value proposition of the solution, highlighting the benefits and outcomes that the customer can expect, and showing how the solution can help the customer achieve their goals and solve their problems. The sales representative should also explore the customer's budget and decision-making process, and offer flexible payment options or discounts if possible.
