## Short answer

New business inflates a metric intended to describe the existing starting cohort. Start with this check: Reconcile opening revenue with expansion, contraction and churn from the same accounts. The corrective action is to exclude new-logo revenue from the cohort calculation and report it separately.

## Key takeaways

- Reconcile opening revenue with expansion, contraction and churn from the same accounts.
- Exclude new-logo revenue from the cohort calculation and report it separately.
- Use consistent recurring-revenue definitions and currency treatment.
- Review opening-cohort revenue reconciled through the period.

New business inflates a metric intended to describe the existing starting cohort. The useful response is a diagnosis that changes a decision, not another report describing the symptom. Use this play with the metric owner and the source-system owner. The working evidence should include metric dictionary, source records and cohort definition, with private or sensitive details removed from any shared example.

## Confirm the problem in the actual workflow

Reconcile opening revenue with expansion, contraction and churn from the same accounts. Start with one representative case and follow it from the original action to the reported outcome. Identify where the observed behavior first differs from the intended process. A screenshot of a final dashboard can be useful, but it may hide the source record, a delayed update or a decision made elsewhere.

Keep the unit of analysis explicit: a consistent account, user, event or revenue cohort. The same label can conceal different populations or stages. Before comparing two results, check that they describe the same kind of work and have had a comparable chance to complete it.

## Separate the visible symptom from the cause

Write the numerator, denominator, unit, period, source and exclusions before interpreting the number. Separate observed data from assumptions and forecasts. A metric can be calculated correctly while still answering the wrong business question.

The symptom in this case is specific: new business inflates a metric intended to describe the existing starting cohort. Ask which piece of evidence would distinguish an operating failure from a measurement failure or a mismatch in the original plan. If the evidence is unavailable, record the missing source and its owner instead of treating the preferred explanation as established fact.

## A situation to work through

A strong acquisition month cannot repair a weak retention metric by being added to its numerator.

This is an illustrative situation, not a reported client case. Record the equivalent evidence and assumptions for your own workflow.

## Choose the smallest useful correction

Exclude new-logo revenue from the cohort calculation and report it separately. Keep the change narrow enough that the responsible people can implement and inspect it. If a correction changes several things at once, describe it as a combined operating change; do not later claim that one small element caused the whole result.

Assign the correction to the metric owner and the source-system owner. Agree which artifact will show that the work is complete. An owner without an observable acceptance condition can close a task while leaving the original problem unresolved. A detailed checklist without an owner creates the opposite problem: the evidence requirement exists, but nobody is accountable for producing it.

## Preserve the important limitation

Use consistent recurring-revenue definitions and currency treatment. This condition belongs beside the recommendation because it can change the decision. It should not disappear when the plan becomes a short presentation or a status update.

Twenty activated accounts divided by eighty eligible accounts is 25%. Dividing the same twenty accounts by two hundred individual signups produces 10%, but it mixes units. Both inputs can be real while the second ratio is unsuitable for an account-activation claim.

## Verification worksheet

| Review item | What to record for this issue | Owner | Evidence |
| --- | --- | --- | --- |
| Observed symptom | New business inflates a metric intended to describe the existing starting cohort. | | |
| Diagnostic test | Reconcile opening revenue with expansion, contraction and churn from the same accounts. | | |
| Proposed correction | Exclude new-logo revenue from the cohort calculation and report it separately. | | |
| Guardrail | Use consistent recurring-revenue definitions and currency treatment. | | |
| Review measure | Opening-cohort revenue reconciled through the period | | |

Download a working copy and follow the [worksheet instructions](/resources/#using-worksheets). Keep unknown facts visible rather than filling gaps with guesses.

## Decide whether to keep, revise or stop the change

Review opening-cohort revenue reconciled through the period after the agreed observation period. Keep the correction when the intended behavior is verified and the guardrail remains acceptable. Revise it when the diagnosis was useful but the intervention did not resolve the cause. Stop and reassess when new evidence shows that the original problem was framed incorrectly.

Record what changed in metric dictionary, source records and cohort definition. This gives the next review a stable starting point and prevents a definition change from being mistaken for a performance improvement.

## Frequently asked questions

### What is the first diagnostic check?

Reconcile opening revenue with expansion, contraction and churn from the same accounts. Inspect the actual working record or customer path rather than relying only on a summary report.

### What should change after the diagnosis?

Exclude new-logo revenue from the cohort calculation and report it separately. Record the owner and the evidence needed to verify the correction.

### What limit should the team keep visible?

Use consistent recurring-revenue definitions and currency treatment. A local improvement does not establish a universal benchmark or guarantee a commercial result.

### How should the correction be evaluated?

Review opening-cohort revenue reconciled through the period using a consistent unit and observation window. Keep the original evidence and record any measurement changes.
