The main function of the Controller's Office is to properly record and maintain records for all money spent or received by the City. The City operates on a fiscal year which is from July 1 to June 30. Budgets are prepared annually for each fund such as general, water, special projects, etc. These budgets are used as guidelines for expected revenues and expenditures. A department purchasing goods or services must submit a purchase order for approval. As the goods or services are received and approved by the department and the City Council for payment, checks are drawn for the purchase or service. Bi-weekly payrolls for the City's employees are prepared and paid. When goods or services are purchased from the City, invoices are issued. There are also three water billing cycles, each of which are billed on a quarterly basis. Regular collection procedures are followed. A monthly financial report is submitted to the Mayor and Council. At the end of each fiscal year, an independent auditing firm reviews the City's records. Changes and recommendations are incorporated into the financial recordkeeping system of the City.
