The board of county commissioners is required by law to hold, at the county seat, a regular meeting on the first Monday of each month to transact county business. The agenda might include legal, personnel and fiscal matters. In practice, more frequent meetings are held and an agenda is posted in advance within the courthouse The board of county commissioners' business meetings are open to the public.

By law, the commissioners must act as a board when entering into contracts or other agreements affecting the county's welfare. Thus, actions taken by the board are voted on and approved by a majority of the commissioners.

The board of county commissioners has legal powers when acting in the county's welfare. Among the powers granted by law are the authority to:
Sell or purchase public land or buildings for the county.
Call a county bond election for approving a public project or creating a special district.
Incur public indebtedness in the county's name.
Implement an economic development program for the ocunty.

The board of county commissioners plays an integral partin the receiving and expending county funds. As the county's chief administrative body, the three county commissioners must make major financial decisions and transactions. Also, the board of county commissioners has the official duty to ensure the fiscal responsibility of the other county officers who handle county funds. By law, the board has the power and duty to audit the accounts of all the officers who receive and manage money belonging or appropriated to the county.

The board of county commissioners also has a role in the county budget process. Near the end of each fiscal year, the board must collect from each elected and nonelected county official a financial statement showing their expenditures and remaining revenues for the current fiscal year, and their estimate of needs for the upcoming fiscal year. Furthermore, the board is required by law to prepare a statement showing the county's current financial condition, and the anticipated revenues forthe upcoming fiscal yar along with an estimate of needs for each county office. The county clerk assists the board of county commissioners in carrying out these duties. The information is pubished in newspaper by the board of county commissioners and submitted to the county excise board. Final authority for funding each county office lies with the county excise board.

Unlike the misconception that county commissioners are only elected to build and maintain county roads and bridges, as members of the board of county commissioners, they are foremost policy makers and business managers for the county. All the review and approval procedures empowered to the board are a means to provide the public with a fiscally efficient system of county government.
