Fractional CFOs under $20,000 a month
16 firms and practitioners publish a fractional CFO fee under $20,000 a month. A published floor is the cheapest way in, read from each listing's own site; the role page carries the ones that quote instead. First on the list are airCFO, Altus CXO and Bennett Financials.
Published fractional CFO retainers run $3,000 to $12,000 a month, with $5,000 to $8,000 the common band for a $1M to $20M company; bookkeeping is often billed on top.
