The Business Office of the Archdiocese handles the financial requirements and manages the temporal goods of the Archdiocese by maintaining records for all business-related matters. It collects assessments for Central Diocesan Operations and Priest Retirement. The office issues each priest their W-2 forms at the end of the year, relieving the parish of the responsibility. A yearly audit is performed by a national firm with results provided to the Archdiocese through the Sooner Catholic.

The office assists parishes in obtaining loans, preparing deeds, mortgages, mortgage releases and lease agreements. It contracts with hospitals and prisons for chaplain services and administers the retirement and insurance plan for all employees of the Archdiocese. It supports the duties of the Safe Environment Office as it manages volunteers and employee applications, background checks and training records through the Web-based database.
