What a $300K CFO Actually Does (And How to Get 80% of It for $149/mo)
April 7, 2026 · 8 min read · By Josh Menold
I've been a CFO. I've hired CFOs. I've fired CFOs. Here's what the good ones actually do — and which parts you can get without writing a $300K check.
What a Great CFO Does Every Week
Let me break down a typical week for a CFO at a $10M-$50M company:
Monday
- Review cash position across all accounts
- Check AR aging — who's late, how much is at risk
- Review last week's revenue vs. forecast
- Update 13-week cash flow forecast
- Flag any upcoming cash crunches to the CEO
Tuesday–Wednesday
- Deep dive on margins by service line or product
- Analyze customer profitability — who's worth keeping
- Review hiring requests against financial capacity
- Work on pricing strategy or cost reduction initiatives
- Meet with ops leaders about project profitability
Thursday–Friday
- Strategic work — M&A evaluation, capital allocation, growth planning
- Board/lender reporting and relationship management
- CEO advisory — framing decisions with financial data
- KPI review and weekly scorecard update
- Month-end close oversight (week 1 of month)
The 80/20 Split
Here's the insight that changes the math: roughly 80% of what a CFO does is analytical and can be templated, automated, or AI-assisted. The other 20% is judgment, relationships, and strategic thinking that requires a human in the room.

15 out of 20 core CFO activities can be done with AI tools today. That's 75% — and for most businesses under $20M, those 15 activities are 90% of what they actually need.
The Math
When You DO Need a Real CFO
I'm not going to pretend AI replaces everything. You need a real CFO (or fractional) when:
- You're doing an acquisition or being acquired
- You need to raise capital or negotiate with lenders
- You're preparing for an IPO or major liquidity event
- You have complex multi-entity or international tax structures
- You need someone in the board room representing finance
For everything else — the weekly cash check, the margin analysis, the hiring decision, the pricing review, the board report — AI tools get you 80% of the way there at 0.5% of the cost.
The question isn't “can I afford a CFO?” The question is “can I afford to keep flying blind while I wait for one?”
