What is customer attestation?
Customer attestation is a customer's identity-assured confirmation that a specific milestone or outcome is true — captured as an immutable record that downstream systems can rely on. Where a survey samples sentiment and a health score infers a state, an attestation is the customer's own act: they reviewed a stated outcome and put their name to it, and the record of that act cannot be silently altered afterward.
The test for whether something is an attestation is reliance: does anything downstream treat it as truth? In ValueRoom, attested state is what the health signal is checked against, what the renewal case cites, and what qualifies the forecast — which is why the record has to carry an identity grade and an append-only history. A confirmation nothing relies on is just a checkbox.
The reason
Why it exists
Every instrument the revenue stack uses to know the customer — usage analytics, sentiment, health scores, rep notes — is the seller observing the customer from the outside.
Observation can show what a customer did. It cannot show what the customer agrees is true. Attestation exists because the highest-grade evidence about an account isn't observed at all — it's confirmed, by the customer, on the record.
It matters more, not less, as AI enters the stack. An AI acting on observed signals inherits their ambiguity; an AI grounded in attested state reasons from facts both sides accepted. And when the buyer's side runs an agent of its own, a countersigned record is the thing that agent can verify and trust.
Often confused with
How it differs from the adjacent instruments
A survey / NPS response
A sentiment sample — often anonymous, never about a specific outcome, and nothing downstream relies on it.
A health score
An inference from observed signals. An attestation is the ground truth an inference should be checked against.
A MAP checkbox
A tick that usually carries no identity assurance and has no downstream reader. An attestation is identity-assured and load-bearing.
An e-signature
Executes a document at the deal's edges. An attestation confirms a value outcome during the relationship.
Questions
Frequently asked
What makes an attestation trustworthy?
Three enforced properties: the vendor can never make it alone (bilateral), the confirmer's authentication is recorded (identity-assured), and the history is append-only at the database (immutable).
Is customer attestation the same as a testimonial?
No — a testimonial is marketing collateral. An attestation is an operational record: specific outcome, specific identity, specific timestamp, consumed by the systems that measure the account.
Enforced, not just promised. The guarantees behind these terms (append-only records, the records-nothing buyer lane, the buyer-side firewall) are enforced in our system and checked by automated tests. Read the live trust protocol
