Publishing what a consultation costs changes who fills in the form
Money on the page filters before your staff have to, and reads as confidence to a reader who has been quoted vaguely elsewhere.
Most firms leave fees off the site out of fear of scaring people away. What actually happens is that price-sensitive inquiries still arrive, only later, after twenty minutes of somebody's time.
A number does the sorting for free. It also separates you from the firms that will not say, which is a real distinction to a reader who cannot tell any of you apart yet.
You do not need a full schedule. A consultation fee, a sentence about how flat fees are structured for the matters you take, and a plain note that government filing fees are set by the government and change from time to time will cover most of it.
Attorney advertising rules apply to how fees and services are described. Worth confirming the exact wording with your own counsel before publishing.
