Church finance carries obligations that general CFO work doesn't prepare you for: fund accounting, designated and restricted giving, capital campaigns and building funds, clergy compensation structures and housing allowances, and a congregation that gives sacrificially and trusts leadership to steward every dollar with care.
Most churches cannot justify — and do not need — a full-time CFO. They do, however, need executive financial leadership: someone who sits beside the senior pastor, executive pastor, elders, and finance committee; speaks the language of both the budget meeting and the boardroom; and brings the discretion that ministry leadership quietly depends on.
