Fractional Finance Ops and 13-Week Cash Forecast Service for Agencies
A monthly retainer that gives agency and studio owners a rolling 13-week cash forecast, hiring runway model, and one clear financial decision each month.
The problem
Agency and studio owners are profitable on paper and broke in the bank. Project revenue is lumpy, clients pay late, payroll is fixed, and nobody in the business owns cash. Bookkeepers report the past, accountants file taxes, and neither one tells the owner whether they can hire in March. Owners make hiring and pricing decisions on gut feel and then panic in a slow quarter.
Why now
Bank feed APIs and forecasting tools such as Float, Fathom, and Syft now plug straight into Xero and QuickBooks, so the modelling work that used to take days is mostly configuration. Agencies have also been through a volatile few years of client churn, which made cash visibility a felt need rather than a nice-to-have.
Who pays
Owners of 5 to 50 person agencies, design studios, dev shops, and consultancies with $500k to $10M revenue in the US, UK, Canada, and Australia who already have a bookkeeper but no finance lead.
How it makes money
Monthly retainer $1,000 to $4,000 depending on headcount and complexity, plus a one-time $2,000 to $5,000 setup for the initial model and chart of accounts rework. Optional project fees for fundraising or acquisition prep.
Market & demand
Order-of-magnitude: tens of thousands of agencies in this size band across the four markets. A solo operator with 12 retainers at $2,000 per month is a strong six-figure practice with no staff.
The fractional executive model has normalised, and agency-specific benchmarking content has created a vocabulary (utilisation, delivery margin, agency gross income) that owners now recognise. That makes the sale easier than it was five years ago.

SWOT
Strengths
- Near zero startup cost and immediate revenue
- High-trust, high-retention relationship
- Clear differentiation from bookkeepers and tax accountants
Weaknesses
- Time-for-money without productisation
- Depends heavily on your credibility and track record
- Capacity ceiling as a solo operator
Opportunities
- Productise the model into a template and hire junior analysts
- Vertical expansion into other project-based businesses (construction, film)
- Referral partnership with agency bookkeepers who do not do advisory
Threats
- Owners deciding forecasting tools alone are enough
- Recession squeezing agency budgets, retainers get cut
- Race to the bottom from offshore fractional CFO marketplaces
Competition & the gap
Fractional CFO firms, agency-specialist consultancies such as Parakeeto and Summit CPA style practices, forecasting software (Float, Fathom), and generic accountants offering advisory add-ons.
The wedge: Most fractional CFOs are generalists. Deep agency-specific operating knowledge (utilisation, scope creep, retainer versus project mix) plus a repeatable 13-week cash model is a narrow, defensible position.
Go-to-market
Publish an agency cash and margin benchmarking teardown series, offer a free 30-minute cash review that produces a one-page forecast, and convert into retainer. Speak at agency owner communities.
First 10 customers: Do 10 free cash reviews for owners in agency communities (Bureau of Digital, Agency Hackers UK, Slack groups). The review itself is the sales pitch because it shows them a runway number they did not have.
How to set it up
- 1Build a reusable 13-week cash forecast model and agency chart of accounts template
- 2Set up Float or Fathom connected to Xero and QuickBooks for delivery
- 3Define the monthly deliverable: forecast, one KPI review, one decision recommendation
- 4Run 10 free cash reviews to test the pitch and gather testimonials
- 5Set retainer tiers and a written engagement scope
- 6Build a partner referral loop with agency bookkeepers
How to validate it
Free reviews convert to retainers above one in four, clients renew past six months, owners start bringing hiring and pricing decisions to you before making them, and referrals arrive without being asked.
Key risks
- Be careful about the line between finance operations and regulated investment or financial advice. Cash forecasting and management reporting for a company is fine. Advising an owner on personal investments or products is regulated in the US (SEC or state), UK (FCA), and Australia (ASIC), so do not stray there
- You carry reputational risk if a forecast is badly wrong, so document assumptions and use scenario ranges
- Capacity ceiling caps growth unless you productise
Your moats
- Agency-specific benchmark data across your client base
- Reputation and referral density in a tight community
- Reusable model and SOPs that make delivery fast
