Two enrollment levers that work: fraud-as-trigger and the liability letter

The underlying principle.

Both mechanics work for the same reason: people don't act until the cost of inaction is visible. Positive Pay is abstract until the moment a business client can see what not having it costs them. Both levers manufacture that moment.

Lever A: Fraud-as-trigger.

The mechanic: when a commercial client experiences check or ACH fraud, your FI requires them to open a new account. At that moment, they face a choice: enroll in Positive Pay (offered at the point of fraud) or sign a hold harmless agreement accepting liability. Most choose Positive Pay.

A community FI built most of its 100+ commercial PP book this way. Their leadership confirmed: life-to-date, the majority of enrollments came through this path, not proactive selling. The fraud incident does the persuading. Your job is to make enrollment the obvious, frictionless choice in that moment.

"Most of our 100+ Positive Pay customers came in after a fraud incident. We don't sell it. We make it the obvious choice at a moment when they're listening."

Lever B: The liability letter.

The mechanic: proactively mail your commercial clients with above-average balances. The letter does three things: states that business payment fraud is rising, clarifies that per the account agreement the business is liable for losses, and offers Positive Pay as protection. It includes a response form with two boxes: "I Accept" or "I Decline."

A community FI sent this mailer to business members with $10,000+ average balances. Sixteen "Accept" responses came back in 48 hours.

"We sent a mass mailer to our business members notifying them they're liable for any fraud and that we now offer Positive Pay. In just two days I received 16 forms back checked 'I Accept.'"

Which lever fits your FI.

Fraud-as-trigger is reactive. It requires no campaign, just a consistent internal process for every fraud incident. It fits FIs with steady fraud volume and a treasury team that can move fast at the moment of an incident.

The liability letter is proactive. It requires a mailer, a response form, and follow-up capacity to send setup forms to everyone who accepts. It fits FIs that want to clean their existing book quickly and have the bandwidth to handle a response spike.

Stack them.

The strongest FIs run both. Use the liability letter to proactively convert your existing book. Use fraud-as-trigger as the permanent, ongoing mechanism for every business client that experiences fraud going forward. One cleans the backlog, the other prevents it from rebuilding.

Do this

Pull a list of your commercial accounts with above-average balances. Draft a liability letter in the next 30 days. Target a 5–10% positive response rate in the first 60 days.

3 quick questions

Why do both enrollment levers work?
A They're cheaper than other methods
B They make the cost of inaction visible at a moment the client is listening
C They're required by regulation
D They eliminate the need for treasury staff
Correct. Both levers work because they manufacture the moment when the cost of inaction becomes visible — and that's when people act.
Not quite. Both levers work for the same reason: they make the cost of inaction visible at a moment the client is listening.
What's the core mechanic of the liability letter?
A A discount offer
B Clarifying the business is liable for fraud, then offering PP as protection with an Accept/Decline form
C A free trial
D A webinar invitation
Correct. The liability letter states fraud is rising, clarifies business liability, and offers PP as protection — with a simple Accept/Decline response form.
Not quite. The liability letter clarifies the business is liable for fraud losses, then offers PP as protection, with an Accept/Decline response form.
How should the two levers be used together?
A Pick one and stick with it
B Liability letter to clean the existing book, fraud-as-trigger as the ongoing mechanism
C Run them in alternating years
D Only use both if you're over $5B in assets
Correct. Stack them: the liability letter cleans the backlog, fraud-as-trigger prevents it from rebuilding.
Not quite. Stack both: use the liability letter to convert your existing book, and fraud-as-trigger as the permanent ongoing mechanism.
