If we have no fee-for-service programs, do we still need marketing?

Summary:

Regardless of the makeup of your funding base, you need to market your organization

You should market your organization no matter what the source(s) of your
funding. Every step in getting contracts and grants should be approached as a
marketing project. Conducting an agency site visit and
or renegotiating contracts are both marketing activities. Making your
facility look good, briefing your people, planning for negotiations,
working through local politicians, all involve good marketing. Of
course, fundraising is a specialized form of marketing. (There is a good
deal of information about fundraising and development elsewhere in The
Nonprofit FAQ.) See, for example, the various topics grouped at http://www.idealist.org/en/faqcat/100-7.
