One of the most frequent questions I receive
from those who are trying to start or grow
their own consulting business is: “How and
what do you charge clients for your consulting
The ways of billing clients are numerous.
There are hourly rates, by-the-job fixed rates,
contingency or performance arrangements,
flat fee plus expenses, daily fee plus expenses,
and many other methods of charging for your
consulting services. Which one is best?
Let us consider some ways of billing for your
1. Hourly or Daily Rate
Many consultants charge by the hour or day.
To establish an hourly or daily rate, they try
to calculate the number of billable hours in a
year. Many hours will be spent marketing and in
administrative and other functions, so this
time is not chargeable to the client. As well,
vacation time, holidays, sick days, and so on,
can not be directly billed to the client.
Consultants, like other businesses, must charge
enough to cover their overhead expenses and also
earn a profit. If a consultant wants to earn
twenty-five dollars per hour of working time,
he (or she) might have to charge one hundred
dollars per hour to the client. This assumes
one half billable hours and fifty percent
overhead and profit.
Your hourly or daily rate may be limited by
what your competition charges, especially if
you have not positioned yourself as different
2. Fixed or Flat Rate
Some consultants charge by the job or a flat rate.
For example, a tax consultant might charge three
hundred dollars to prepare a tax return for
you and your spouse, including an unaudited
income statement for your business from information
supplied by you. If the consultant takes only one
hour to do this, he grosses three hundred dollars
per hour. If, though, the tax consultant
miscalculates the time required, he could take
twenty hours to complete the job and make only
fifteen dollars per hour.
Of course, consultants can also make a profit on
the labour of their employees or subcontractors.
Many consultants claim to make more on a flat rate
than on a hourly basis. Advantages include being
able to give a quote to the client up front and
less disputes on price (as the total bill was
agreed upon in advance). grogan
To protect yourself on flat rate assignments,
always limit the scope of your engagement to
something that you can calculate easily.
For example, if you are asked to give a quote
for setting up a website for a business, you
might break this project into smaller assignments.
First, you could give a quote for preliminary
research and recommendations. Estimate the time
required to meet with the client, learn about
his business and goals, develop strategies and a
budget, and prepare recommendations on how to
proceed. Then, give the client a quote (perhaps
in the form of a one page letter agreement or
proposal). Upon acceptance of the offer by the
client in writing, you may proceed with this
phase of the project.
