No CFO needed: Founder handles financial strategy

Accountant: More complex taxes, potentially audit prep
Consider fractional CFO or controller: Financial complexity increasing, board reporting needed, possible future fundraising

Fractional vs. Full-Time
For CFO/controller roles, fractional (part-time) can work well:
Fractional works when:
•
You need strategic input but not full-time work
•
Budget constraints
•
Specific projects (fundraising, systems setup)
Full-time needed when:
•
Finance work exceeds 15-20 hours/week
•
Continuous strategic input required
•
Building a finance team
Many companies start fractional and transition to full-time as they scale.
Working with Finance Help
Set Clear Expectations
•
What deliverables do you expect?
•
What’s the communication frequency?
•
What decisions need their input?
•
What systems should they use?
Provide Access
Finance people need:
•
Bank and card access (view at minimum)
•
Accounting software access
•
Revenue data (Stripe, billing system)
•
Key contracts and agreements
Regular Check-ins
Bookkeeper: Weekly or as needed
Accountant: Quarterly for planning, monthly during tax season
CFO: Weekly, with formal monthly reviews
Trust But Verify
Review their work:
•
Do financial statements make sense?
•
Are categorizations correct?
•
Do projections seem reasonable?
You don’t need to be an expert, but you should understand the basics.

•
Errors are increasing

Accountant → Better/bigger accountant:

•
Poor communication
No CFO → Need CFO:

Common Mistakes
Hiring too late: By the time you’re drowning, you’ve already made mistakes.
Hiring the wrong type: Getting an accountant when you need a bookkeeper, or vice versa.
Not vetting for startup experience: Corporate finance is different from startup finance.
Penny-wise, pound-foolish: Cheap bookkeeping that requires expensive cleanup.
Abdication without oversight: Handing over finance and never looking at it.
