Have you ever been into a coffee shop that doesn’t have the price list posted?
Probably not.
What if, for example, you were hiring a contractor to complete a renovation on your house. Do you trust the contractor who says it will cost $30,000? Or the contractor that says it will cost $35,000 and then takes you line by line through his process to get to that number?
Clarity on your pricing facilitates trust with your customers. Having your price list available (or at the very least how you calculate the final price, for larger projects) makes a difference.
