Fees are an important part of your business. Got to keep the cash flowing. Better ask yourself some questions and try to view things from your customers point of view.
Why do you want lower fees? Are you trying to grab market share? Or, are you not worth the going rate?
Are your customers price sensitive when making decisions, or are they really looking for something else?
Generally speaking (in my experience), value equals 1) price, 2) speed, 3) quality. Pick 2 of the three. If your price is low, chances are good you are compromising on either speed or quality.
Often, a customer says they want a low price and good quality, but what they really want is good quality and on-time delivery. They will pay to get that, and then they will hire you again.
If you are able to keep costs low by skimping on resources, office space, equipment, or support staff, speed becomes much more difficult to achieve.
Think about your business plan. Are you attempting to gain customers with low fees, but you plan to raise them later? Price increases can be hard to implement, and customers may desert you. It may be easier to start with high fees, say 110% or 120% of the going rate and give a discount to capture customers.
