Referral agreement tail provisions: are you still paid after the agreement ends?

A referral agreement tail provision keeps your right to be paid for introductions made during the agreement when the deal closes or the money arrives after it ends. For SourceX introductions, that depends on the signed partner agreement and published terms, so confirm the attribution window, survival wording and payment condition in writing instead of assuming an M&A-style tail.

The short answer: only if the agreement says the right survives

A tail provision is a clause that preserves your right to be paid for business you introduced during an agreement, even if the money arrives after the agreement has ended. Whether a payment right outlives the contract is a matter of wording: rights already earned are often treated differently from rights that depend on events after termination, and the clause language decides which bucket a pending introduction falls into.

For SourceX introductions the question is practical, because a data license takes time to reach payment. The company has to qualify, complete a data inventory, agree price and terms, go through buyer review and close, and then the buyer has to pay before SourceX collects its fee. The full sequence is set out in how SourceX referrals work.

Two published facts frame the answer. Credit goes to the first valid referrer whose introduction leads to a verified company application within the attribution window. And 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, payable only after the buyer pays and SourceX receives its fee. Anything tail-like beyond those two facts is set by your signed partner agreement and the program terms, so confirm it there rather than assuming it.

How does a tail work in an M&A engagement letter?

Sell-side bankers and business brokers already know the idea. In a typical engagement letter, the tail says that if the client closes a transaction within a set number of months after the engagement ends, with a party the advisor contacted or introduced during the engagement, the advisor still earns the success fee. The negotiated details are familiar:

Length: how many months the tail runs after termination.
Covered parties: every party contacted, or only those on a list the advisor delivers when the engagement ends.
Trigger: a signed letter of intent, a signed purchase agreement or a closing inside the tail.
Cause: whether the tail survives if the client terminates the advisor for cause.

A referral agreement can borrow any of these ideas, but none of them is implied. Treat M&A habits as a checklist of questions to ask, not as a description of what a referral program contains.

Tail, survival and attribution clauses compared

Clause	What it does	Engagement letter version	What to look for in a referral program
Tail period	Keeps fees payable for deals that close after termination	A set number of months, tied to parties contacted	Whether introductions made before termination can still earn a reward
Survival clause	Lists which obligations outlive the agreement	Fees, confidentiality, indemnity	Whether payment obligations and the attribution record survive
Attribution window	Decides who gets credit for a company	Rarely needed; the client appoints one advisor	How long after an introduction a verified application still counts
Payment condition	Sets the event that makes money due	Closing of the transaction	Buyer payment and SourceX's receipt of its fee
Termination for cause	Removes rights after a breach	May cut off the tail	Whether a breach forfeits pending rewards
Notice and records	Fixes how pending matters are documented	A tail list delivered at termination	Whether you can request a dated list of your pending referrals

How pending introductions play out: situations to check

Situation	What to check	Outcome to confirm in writing
You introduced a company, it applied inside the window, then you stopped referring	Survival and termination wording	Whether the introduction stays attributed to you
Your agreement ends before the company signs a license	Whether rights tied to earlier introductions survive	Whether a later closing still earns a reward
The license is signed but the buyer pays months later	The payment condition	That the reward follows buyer payment and SourceX's receipt of its fee
Another partner introduced the same company first	The first-valid-referrer rule	Which introduction was recorded first
The company paused and came back a year later	How the attribution window is measured	Whether the original introduction still counts
You move to a new firm mid-process	Who the registered payee is	Whether the payee can be updated, and how
The owner applied without using your referral link	How your introduction was recorded	Whether your referral form submission was logged first

What the law adds after the agreement ends

Two legal points follow you past termination.

Tax reporting. A reward that arrives after you have stopped referring is generally still taxable income. IRS Publication 525 explains that an amount included in income is taxable unless the law specifically exempts it, so keep your tax forms and payment details current for as long as any introduction is pending.
Old public links. If your referral link stays on a website, newsletter archive or profile after you stop actively referring, the material connection still exists while the link can earn you a reward. The FTC's Endorsement Guides, including section 255.5 on disclosing material connections, call for that connection to be disclosed; keep a clear disclosure beside the link or take the link down. The same logic applies to private introductions, covered in do you have to disclose a referral fee.

This is general information, not legal, tax or financial advice. Confirm with your own counsel or tax adviser before relying on any clause.

How to protect introductions that are still pending

Introduce every company through your referral link or the referral form, so each introduction carries a date and your code.
Keep your own log: company, date, sponsor's name and title, and the last status you heard.
Before you end your agreement, change firms or stop referring, ask SourceX in writing for a dated list of your pending introductions and how the terms treat each one.
Read the survival and termination clauses in your signed agreement alongside the published terms, and keep a copy of the version in force when you made each introduction.
Keep payee, tax and bank details current until every pending introduction has resolved.
Stay in the introducer's lane. A partner who starts negotiating terms looks less like a referrer, and the finder's fee vs referral vs broker comparison explains why that matters.

Questions to ask before you sign or end an agreement

Which obligations survive termination, and is the reward one of them?
How long is the attribution window, and from what date is it measured?
What happens to an introduction that is mid-qualification when the agreement ends?
Does termination for cause, or for convenience by either side, change pending rewards?
If I move firms, can the payee change, and who must agree? The page on whether a referral fee should be paid to you or your firm helps you settle that early.
How will I hear that a pending company has closed and that payment has been made? The guide on how to get paid for referrals covers the mechanics.

Next step

Read the terms before your first introduction, not your last. Then register as a partner and draft each introduction with the introduction email builder, keeping the sent email so your record of every introduction starts with a dated, owner-approved message.

Common questions

How long is a typical tail period in a referral agreement?

There is no standard length. Tail periods are negotiated, and many referral agreements have no separate tail at all, relying instead on an attribution window and survival language. For a SourceX introduction, read how the attribution window is measured and which obligations survive termination in your signed agreement and the published program terms, rather than borrowing a period from M&A practice.

Is a tail period the same as a survival clause?

No. A survival clause lists which obligations continue after the agreement ends, such as confidentiality or payment of amounts already earned. A tail period is a specific post-termination payment right for deals that close within a set time with parties introduced earlier. A contract can have either, both or neither, which is why the exact wording matters more than the label.

Does a signed license agreement mean my reward has been earned?

No. A signed agreement, a meeting or a qualified lead does not trigger payment. The reward becomes payable only after the buyer pays and SourceX receives its fee. If your partner agreement ends in the gap between signing and payment, check how its survival terms treat that gap before you assume either outcome.

Could a company wait out my agreement to avoid my referral reward?

The company gains nothing by waiting, because the reward is paid by SourceX as a share of its own fee and is never deducted from what the company receives. Credit is tied to the first valid referrer whose introduction leads to a verified company application within the attribution window, so the questions worth asking concern that window and your agreement's survival terms.

What should I do before switching firms with introductions pending?

Ask SourceX in writing for a dated list of your pending introductions, read your agreement's termination and survival clauses, and agree with both your old and new firm who should be the payee. Settle it in writing before you leave, because a payment can arrive long after the introduction and the people who remember the arrangement may have moved on.
