A referral program for fractional controllers who know where the records live

Fractional controllers can join SourceX's partner referral program and earn 25% of the eligible platform fees SourceX collects when a client they introduce licenses its operational records, capped at $100,000 per referred company and paid only after the buyer pays. Controllers share fit information only, never records, and bring in the CEO, owner or CFO as sponsor.

Why fractional controllers are well placed

A fractional controller runs the close, reviews AP and payroll, keeps reconciliations current and often administers the accounting system. That puts you closer to a company's records than almost any outside adviser: you know how far back the general ledger goes, whether the old desktop accounting file was archived before the move to a cloud ERP, who can run exports and which systems feed the books.

That first-hand knowledge is exactly what matters at the start of a data licensing conversation. Companies that license operational records to AI developers need years of history across many systems and someone able to export it, and you can usually tell in one conversation whether a client is close. What you pass on is fit information only. The records stay with the company, and the decision belongs to its owner, CEO or CFO.

Which clients in your book fit

Most fractional controllers serve several companies at once. Screen them against these signals.

Signal	What to look for	Why AI buyers care
Size	50+ full-time employees at peak, contractors excluded	More people produce more connected records of real work
History	Several years of documented operations; 5-10+ years is stronger	Long histories show how processes and decisions changed
System count	Books plus CRM, support, project, HR, email and chat; strong candidates often run 10-15+ systems	Linked systems show whole workflows rather than fragments
Export ability	Someone can still pull data from current and retired systems	Data that cannot be exported cannot be delivered
Origin of records	The company generated the records rather than processing them for its clients	Buyers need clean rights before anything moves
Sponsor access	You can reach the owner, CEO or CFO directly	Only an authorized sponsor can start the process

B2B software, IT and managed services, professional services, engineering, logistics, distribution and the back offices of manufacturers tend to screen well. Businesses that mainly handle their clients' data, such as some agencies and outsourcers, usually do not.

The close-desk screen

A controller's fit test takes five questions. If any answer is a clear no, park the client and revisit later.

Depth: does the general ledger, or an archive of it, go back several years, and do other systems go back as far?
Breadth: beyond accounting, does the company run CRM, support, project, engineering or operations tools that people actually use?
Exports: has anyone run a full export in the past year, or could they?
Rights: did the company create these records, and do client contracts leave it free to license internal material?
Sponsor: will the owner, CEO or CFO take a short call about it?

The company fit checker runs a preliminary, non-binding version without asking for contact details, and who qualifies sets out the full baseline.

When to raise it in the controller's calendar

Moment	Why it works	What to bring up
Monthly close review with the owner or CEO	You already discuss the business and its systems	Whether the company would consider earning from records it already keeps
Budget season	Leadership wants revenue that needs no new headcount	A one-time license as possible upside, never a budget line
Year-end close and audit or review prep	Records are being gathered and retention is on the agenda	Which archives are complete, and who controls exports
Accounting system or ERP migration	Old systems are about to be retired	Archiving full history before the old system is switched off
Retention policy review or file purge	Records are about to be destroyed	Pausing deletion of long histories until the owner decides
Sale preparation or quality of earnings work	The owner is reviewing every asset	Timing a license before or after the sale, with the deal team
Engagement renewal	The scope and value of your work are under discussion	Data as an asset you helped surface

Year-end conversations overlap with tax planning; when to raise a possible data license at a year-end planning meeting has a meeting-ready version.

What you can share, and when to hand over to the sponsor

Your role ends at the introduction. Keep a clear line between fit information and records.

You can share	You never share
Company name and the sponsor's contact details, with their permission	General ledger detail, trial balances or financial statements
An approximate headcount band at peak	Customer, vendor or employee lists
Years of history and which systems are in use	Exports, screenshots or sample files from any system
Whether exports appear possible	Descriptions of what specific records contain

Bring in the sponsor before you submit anything. The owner, CEO, CFO or another authorized representative has to be willing to explore a license, and a controller cannot commit the company. Asking the sponsor's permission before you name the company also respects the confidentiality terms in your engagement letter.

How the introduction works

You raise it with the sponsor and get agreement to an introduction.
You join the partner program, then either share your referral link, which sends the company to sourcex.si/apply with your referral code attached, or submit the company through the referral form.
SourceX reviews size, history, breadth of data and rights directly with the sponsor.
The company builds a data inventory: each system, how far back it goes and what can be exported.
The company and SourceX agree price and terms; nothing is binding until the company signs.
AI labs and data buyers review the opportunity, typically responding within about two weeks once the company is deal-ready.
After signing, data is prepared under the redaction rules set at the outset and delivered with the company's authorization, and the company is paid.
Your reward is paid once SourceX has received its fee.

At no point do you export, upload or forward records.

What to say to the owner or CEO

How rewards work for a fractional controller

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. A reward becomes payable only after the buyer pays and SourceX receives its fee; an introduction, a meeting or a signed agreement on its own does not trigger payment, and no reward is guaranteed. The reward is a share of SourceX's fee and is never deducted from what your client receives. Credit goes to the first valid referrer whose introduction leads to a verified company application within the attribution window, and the program terms set the remaining details.

Three checks before you register:

Professional rules. If you hold a CPA license, the AICPA Code and your state board govern referral fees and disclosure, and state rules can be stricter than the AICPA Code, as the New Jersey Society of CPAs' resource on commissions and contingent fees shows. If your firm also performs attest work for the client, read how CAS teams screen attest clients before a compensated introduction first.
Disclosure. Tell the client in writing that you are a referral partner and how you are paid, before the introduction.
Tax. Referral payments may be taxable income to the recipient; IRS Publication 525 explains what counts as income. Confirm your own treatment with a tax adviser.

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

Skip the introduction, or wait, when:

The client never reached 50+ full-time employees at peak (contractors excluded).
Most of its records belong to its own clients, as with outsourced bookkeeping or agency work, and those clients have not consented.
The data is mostly consumer personal information or protected health information.
Old systems were shut down without an export, and the archives are gone.
The company already licensed the same data for AI training.
The owner will not consider an exclusive license; talk it through using exclusive data license opportunity cost.
Nobody you can reach has authority to sponsor it.

A client that fails today may qualify later, for example once a migration is finished and the old system's history is safely archived.

Next step

Run your current client list through the close-desk screen at your next month-end. When one passes and the sponsor agrees, register as a partner and make the introduction. For the broader finance-adviser view, see the fractional CFO partner page.

Common questions

Can I refer a client if I only work there a few days a month?

Yes. What matters is whether the company fits and whether you can introduce its owner, CEO, CFO or another authorized sponsor, not how many hours you bill. Part-time controllers often know the systems and history well because they are the ones cleaning them up. Respect your engagement letter's confidentiality terms by getting the sponsor's permission before sharing the company's name.

Do I need the client's permission before submitting a referral?

In practice, yes. The company's sponsor has to engage with SourceX for anything to happen, and introducing a client without its knowledge can conflict with the confidentiality you owe it. Raise the idea first, explain that you are a referral partner and how you would be paid, and submit the introduction or share your referral link only once the sponsor agrees.

What if my client has shrunk but was once larger?

The size baseline looks at peak headcount: 50+ full-time employees at peak, with contractors excluded. A company that has since shrunk can still qualify if it reached that level and the records from those years still exist. Note the peak year and approximate headcount when you introduce it, and let SourceX assess the rest during qualification.

Does the referral reward come out of my client's proceeds?

No. The partner reward is a share of SourceX's fee, so it is never deducted from what the company receives. The company is quoted one all-in price that already includes SourceX's fee, with no separate charges. Telling the client this up front, along with the fact that you are paid only if a deal closes and SourceX is paid, keeps your disclosure clean.

What happens if two advisers introduce the same company?

Credit goes to the first valid referrer whose introduction leads to a verified company application within the attribution window. If you and another adviser both know the company, the earlier valid introduction counts. Introducing promptly once the sponsor agrees, through your own referral link or the referral form, keeps the record clear. The program terms set the details.
