How a fractional CFO for marketing agencies can spot records the agency actually owns

A fractional CFO for marketing agencies works from timesheets, retainer burn, project margins and client profitability, which also shows whether an agency with 50+ full-time employees at peak keeps years of its own briefs, retrospectives and pitch archives. Agency-owned process records may be licensable through SourceX; client-owned deliverables and client data are not.

Why the agency CFO sees the records first

A fractional CFO for a marketing agency spends the month inside timesheets, retainer burn reports, estimate-to-actual comparisons and client profitability. That work shows, faster than any audit, whether the agency keeps years of its own working record: scoping notes, internal briefs, resourcing decisions, retrospectives and pitch archives. Those agency-owned process records are what AI developers may license through SourceX.

The catch is that an agency's files are full of other people's property. Final creative usually belongs to the client once paid for, client data never belonged to the agency, and freelancers may still own what they made. The CFO is one of the few people who can see both sides of that line, because the SOWs, MSAs and freelancer invoices all cross the finance desk.

You do not need to sort the records yourself. Your job is to notice the pattern, mention it to the owner and pass on basic fit information if the owner wants a conversation. The broader fractional CFO partner page covers the role in other industries.

Which agencies in your book fit?

Most agencies are small, so start with headcount and then look at how projects are documented.

Signal	What to check	Why it matters to buyers
Headcount	50+ full-time employees at peak (contractors excluded); freelancers and white-label partners do not count	Enough staff to produce connected records across many accounts
History	Several years of operations with archived projects, not just current retainers	Long histories show how processes and decisions changed
Time and project data	Timesheets, estimates and job budgets in a PSA or project tool, linked to deliverables	Effort tied to tasks shows how creative and technical work is actually done
Process documents	Internal briefs, creative review rounds, QA checklists, launch runbooks, retrospectives	Decisions and their outcomes, in the agency's own words
New business	Pitch decks, proposal drafts, win and loss notes	Reasoning that led to a result the agency recorded
System spread	Project management, timesheets, Slack or Teams, shared drives, CRM, finance	Records across systems show whole workflows

Performance, content, web development, B2B and healthcare-communications agencies with mature project processes tend to have the deepest internal records. Agencies whose output is mostly media buying inside client ad accounts often hold less of their own.

The who-paid-for-it test

For each record type, ask who paid for it to exist and who the contract says owns it. Only material the agency produced for its own operations is a candidate.

Record	Usually sits with	Position
Timesheets, estimates, staffing plans, rate cards	The agency	Candidate, after removing client identifiers
Internal retrospectives, QA checklists, SOPs, onboarding guides	The agency	Candidate
Pitch work for accounts the agency did not win	The agency, if the prospect did not pay for it	Candidate, subject to any pitch NDA
Final deliverables paid for under an SOW	Often assigned to the client by the MSA	Out unless the contract says otherwise and the client agrees
Client briefs, product plans, brand guidelines	The client	Out
Ad account, analytics, CRM and first-party data	The client	Out
Freelancer output with no written assignment	Possibly the freelancer	Out until ownership is clear

The last row is grounded in copyright law. The US Copyright Office's circular on works made for hire explains that work an employee prepares within the scope of the job generally belongs to the employer, while commissioned work belongs to the commissioning party only in listed categories and with a signed written agreement. Freelancer-heavy agencies should check their contractor agreements for assignment language. This is general information, not legal, tax or financial advice; the agency's counsel makes the final call.

The guide on separating agency records from client-owned work goes record by record.

When should you raise it with the agency owner?

Pick a moment when the owner is already looking at the agency's history and asking what it is worth.

Moment	What you are doing	Opening line
Quarterly client profitability review	Ranking accounts by margin after write-offs	The archive behind these numbers is an asset too
Annual rate card and pricing reset	Rebuilding blended rates from timesheet history	Your timesheet history is unusually complete
Project tool or PSA migration	Deciding what history to move	Before we drop the old projects, keep a full export
New business post-mortem	Reviewing pitch costs against wins	You keep better pitch records than most agencies
Exit or holding-company interest	Preparing financials for a buyer	Buyers will ask what else the agency has built

How the introduction works

Ask the owner whether a short fit call with SourceX would be useful; if not, drop it.
If yes, pass the owner your referral link (the application carries your partner code), or enter the agency yourself in the referral form.
SourceX then confirms headcount at peak, years of operation, record breadth and rights with the owner.
The agency lists its systems and record types in a data inventory, marking client-owned material as excluded.
Price and license terms are agreed before any AI lab or data buyer reviews the opportunity.
If the agency signs, de-identification and redaction follow the rules agreed up front, the records are delivered, and the agency receives one payment.

At no point do you export, forward or summarize the agency's files. You pass on fit basics only: headcount, years in business, main systems and the owner's interest.

What to say

Adjust the first line to what you have actually seen. Do not suggest a value, and do not imply the agency will qualify.

How the reward works for an agency CFO

Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company. Payment comes only after the buyer pays and SourceX receives its fee. An introduction or a signed license earns nothing on its own, and no reward is guaranteed. What you receive is a share of SourceX's fee and is never deducted from the agency's proceeds.

CPAs and CPA firms have extra homework. State rules on commissions and referral fees can differ from, and be stricter than, the AICPA Code; the New Jersey Society of CPAs' overview of commissions and contingent fees is one example of a state-level summary. Check the rule in every state where you are licensed, tell the client about any referral fee, and confirm with your state board or professional body before acting.

When not to bother

Even at its busiest, the agency stayed below the 50+ full-time employees at peak (contractors excluded) baseline.
Most of the work is white-label production for other agencies, so the records belong to their clients.
MSAs assign every work product, including working files, to the client.
Project history lives only in client-owned workspaces the agency loses access to when an account ends.
The owner rules out granting exclusive AI-training rights for a set period.
A sale to a holding company is in diligence and the buyer has not been told.

Next step

Choose one agency client with a long, well-kept project archive and check it with the company fit checker. If it looks promising, register as a partner and introduce the owner, who can also apply at sourcex.si/apply through your referral link. The marketing agencies industry page explains what buyers look for in agency records, and the manufacturing CFO playbook applies the same approach to a very different business.

Common questions

Can an agency license creative work it produced for clients?

Usually not the final deliverables. Most agency MSAs assign paid-for work to the client, and client briefs, brand materials and data were never the agency's to license. What may be licensable is the agency's own record of how it worked: estimates, staffing decisions, internal reviews and retrospectives, with client identifiers removed and subject to the agency's counsel confirming the contracts allow it.

Do freelancers count toward the size baseline for an agency?

No. Only full-time staff count toward the 50+ full-time employees at peak baseline (contractors excluded), so freelancers, white-label partners and offshore production vendors do not count. An agency that relies heavily on freelancers may still qualify on its full-time staff, but it should also check whether those freelancers assigned their work in writing.

What if the agency's project history sits in client-owned tools?

Then the agency may not control it. Work done inside a client's own project space, ad accounts or analytics usually stays with the client, and access often ends with the account. Agencies with their own project management, timesheet and file systems keep the records they can actually license, which is a useful early question in any fit check.

Does a data license change an agency's valuation in a sale?

There is no reliable rule for that, so do not promise it. A license usually means one payment in exchange for exclusive AI-training rights for a fixed period, and any buyer of the agency will want to know about it. If a sale is likely, involve the agency's M&A adviser and counsel before anything is signed.

What should a fractional CFO tell SourceX about an agency client?

Only basic fit information, and only with the owner's agreement: roughly how many full-time staff the agency had at its peak, how long it has operated, the main systems it uses and whether the owner wants a call. Do not share client names, financial statements, timesheet exports or any file from the agency. SourceX collects everything else directly from the agency.
