White-label fractional CFO services: who asks the owner, and whose introduction it is

Why a white-label CFO sees the right clients, and why the brand changes the rules

White-label fractional CFO services are CFO engagements an outside CFO firm delivers under a CPA firm's name. The white-label CFO runs the month-end review with the controller, the 13-week cash forecast, the lender covenant package and the board deck, often from a CPA-firm email address and on the CPA firm's templates. That seat shows which clients hold years of connected records. But the client believes it is working with the CPA firm, so the CPA firm's ethics rules, attest relationships and engagement terms govern any introduction to SourceX.

SourceX handles the licensing work itself for US companies whose operational records are worth licensing: qualification, rights review, buyer review, contracting, delivery and payment, with AI labs and data buyers on the other side. Whoever makes the introduction does exactly that and nothing more; nobody on the CFO side ever handles the data.

The Brand, Book, Bar and Benefit test

Work through four questions with the CPA firm before anyone raises data licensing with an owner. If any answer is unclear, stop and settle it in writing.

• Brand: whose name is on the engagement letter, the invoices and the email signature? The party the client knows should be the one who asks the owner.
• Book: whose client is it under the white-label agreement? That party decides whether an outside introduction is allowed and who registers it.
• Bar: whose professional rules apply? Where a CPA firm's brand is on the work, assume its ethics rules and attest-client restrictions apply until the CPA firm confirms otherwise.
• Benefit: who receives any reward, and how is it disclosed to the client?

Which clients in a white-label book fit

Clients served through CAS or outsourced CFO lines vary widely in size. Look for US businesses that had 50+ full-time employees at peak (contractors excluded), have kept documented operations for several years, own the rights to the records in question, and have a sponsor with authority to sign, whether owner, CEO, CFO or another authorized representative.

Sector briefs help with specifics: the fractional CFO guide for MSPs and IT services firms covers PSA records, and the records playbook for professional services firms covers project and proposal archives.

Whose rules govern, and how to check them

The CPA firm's. Some states adopt the AICPA's commissions and referral fee provisions by reference; Kansas, for example, requires each CPA and firm to comply with them, including interpretations (Kan. Admin. Regs. 74-5-103). The core restriction, no commission on clients the firm attests for plus disclosure of permitted fees, is summarized with its primary source in the independence checklist for restricted entities.

A white-label CFO usually cannot see the CPA firm's restricted entity list or its full roster of attest engagements. Ask the CPA firm to run the check and confirm the result in writing before the owner is approached. If the CPA firm audits or reviews the company, assume it will not allow a reward on that client whoever registers it, and confirm with its independence team.

When to raise it in the shared calendar

How the introduction works when two firms are involved

1. The CFO firm and the CPA firm agree a shortlist, and the CPA firm runs its restricted entity list and engagement checks.
2. Both firms confirm in writing who asks the owner, who registers the introduction and who receives any reward.
3. The person the client knows asks the owner for permission and explains the reward disclosure.
4. The registering party submits the company through the referral form, or sends the owner its referral link, which opens sourcex.si/apply with the referral code attached.
5. SourceX qualifies the company with its sponsor on size, history, data breadth and rights, and the company builds its own data inventory.
6. Price and terms are agreed with the company, buyers review, and once the agreement is signed the data is delivered under agreed redaction rules and the company is paid.
7. Any reward is paid after SourceX receives payment.

Neither firm exports, uploads or describes client records at any stage. De-identification and redaction requirements are agreed with the company before work begins.

What to say to the owner

Keep it in the CPA firm's voice, since that is the relationship the client knows:

How rewards work in a white-label arrangement

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. Rewards become payable only after the buyer pays and SourceX receives its fee, and no reward is guaranteed.

For any one company, the program credits a single introducer: the first valid one whose introduction results in a verified application inside the attribution window. Only one of the two firms can therefore be credited. Whatever the firms agree about sharing a reward between themselves, write it into the white-label agreement or a side letter, and tell the client who receives it.

Partners can join from any supported country, though the companies they introduce must be US companies. A white-label CFO firm based outside the US that receives a payment can expect to be asked for Form W-8BEN-E, which a foreign entity gives to the payer to document its status. Whether any withholding applies depends on the facts, so take tax advice.

This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.

When not to bother

• The CPA firm audits or reviews the company and will not allow a reward on it.
• The white-label agreement bars the CFO firm from outside dealings with the CPA firm's clients, and the CPA firm declines to make the introduction itself.
• The client's records mainly belong to its own customers, as at agencies and outsourcers that work inside client systems, and those customers have not agreed.
• The company has fewer than 50 full-time employees at peak, or its old systems were shut down without exports.
• The owner would not consider an exclusive license for AI training for an agreed term.

Raise the four questions at your next check-in with the CPA firm. Once you agree who registers, register as a partner and screen the first company with the company fit checker.
