Which NRR did you tell the board?
Three teams can compute three different NRRs in good faith. The tells are what the number is computed from, when churn leaves it, and whether you can reproduce it.

Ask three teams at the same company for last quarter's NRR and you can get three answers, all produced in good faith.
Customer Success computes it from renewal opportunities in the CRM. Finance computes it from invoices. The board deck carries whichever number was pasted in last, from a spreadsheet with its own opinions about what counts.
None of these teams is wrong. They're answering different questions: expansion counted when it's planned versus when it's contracted versus when it's billed; churn counted when the CRM gets updated versus when the contract actually ended. Nobody wrote down which question the board was asking.
The three tells
Tell one: what is it computed from? NRR scored from CRM opportunities inherits every habit of the pipeline: optimistic amounts, renewals marked closed before signature, expansion counted at full value from day one. NRR built from contract-level revenue schedules, reconciled to billing, inherits the contracts. Only one of those survives a data room.
Tell two: when does churn leave the number? If churn is recognized when someone updates the CRM, your NRR is a measure of CRM discipline, not retention. The quiet version of this is the churned-but-active account: contract ended months ago, ARR still counted, retention silently overstated. Every stack has a few until someone sweeps for them.
Tell three: can you reproduce it? Take the NRR you reported two quarters ago. Could you rebuild it today, from source data, and land on the same number? If the honest answer is "the spreadsheet has moved on," then the number was a moment, not a measurement. Diligence teams run exactly this test.
What good looks like
One written definition (dollar or logo, cohort basis, churn timing, multi-year handling) with one named owner and a version history. A cohort model built from contracts and reconciled to billing. A bridge, not just a number: starting ARR, plus expansion, minus contraction, minus churn, so the board sees why the number moved. And a snapshot at every close, so any reported quarter reproduces on demand.
None of this is exotic. It's the difference between a number that was assembled and a number that can be attested. And it is precisely the layer the tools sitting on your CRM don't build, because they never touch billing or the ledger.
