What reports do we need to prepare and how often?
Who prepares these reports and who should review them?

Because each nonprofit organization faces different financial issues and has different resources to bring to financial functions, each organization will choose a different set of regular financial reports to prepare and analyze. At different times an organization will need different reports to provide information to support its decision making.
The answer will depend on several factors, including the extent to which the organization is financially stable, the degree and extent to which the financial picture changes during the period, the availability of cash to meet financial obligations, the availability of staff or other professionals to prepare reports, etc.
A mid-sized human service organization in reasonably good shape financially might consider the following schedule of reports:
In a small nonprofit the board treasurer or outside accountant/bookkeeper might prepare the financial information for all in-house financial statements, and work with the executive director to prepare the narrative with financial highlights to be presented to the board. A controller or finance director would prepare these reports in a larger organization. The program director, if you have one, would ordinarily prepare the quarterly fee-for-service report. Similarly, the director of development would prepare the quarterly fundraising report.
The executive director reviews all reports prior to presenting them to board members to ensure that the financial information makes sense and can be translated into issues and opportunities facing the organization. In addition, key staff members such as program directors and the director of development should have the opportunity to review income and expense reports for the whole organization.
When the board is large enough to include a finance committee, that committee reviews all financial statements and reports on financial activity to the full board. In a smaller nonprofit, the executive director might report first to the board treasurer, who can then keep the full board apprised of the organization s financial status.
The finance committee will often review the numbers in greater detail than the full board. The full board may be better able to respond to aggregated information with important financial trends and issues highlighted in an accompanying narrative report. While each board member should have the opportunity to review organization-wide income and expense reports to understand the impact their department's activities have on the whole organization, members who are inexperienced at reading financial statements may get lost in overly detailed statements. To help the board fulfill its oversight function, it is important for the executive director and the finance committee to present the information in as clear and concise a manner as possible.
The audit and management letter are addressed directly to the board of directors because of its oversight function. Typically, the auditor works with the finance staff to prepare federal and state reports and may be included at board meetings during which presentations are given.
