Three sell-side analysts will give you three NRR figures for the same target. Only one of them was computed the same way as last deal’s. You don’t know which.
On a €50M SaaS acquisition, a 4-point error in NRR is worth roughly €2M of misallocated equity value at typical multiples. FinArrow runs the calculation deterministically, so the error is visible — not hidden.
The error doesn’t announce itself. It arrives as a footnote in the IC memo, six months after the wire.
NRR computed three ways across three sell-side decks for the same target. Cohort window varies. Churn convention varies. The IC sees one number.
FinArrow fixes a 12-month cohort window, caps GDR at 100%, and logs every assumption.
Your analyst rounded the partial month. The retention curve looks flat. The actual cohort fell off the cliff in month seven.
Point-in-time monthly sums — never a running total. Trailing partial months are dropped, not smoothed.
Onboarding, setup, and professional-services fees billed monthly slip into the recurring line. The ARR looks larger than the subscription base that actually renews — often a double-digit overstatement.
FinArrow separates recurring revenue from one-off and setup fees at ingest, and flags any period where the one-off share crosses a set threshold.
Send us your billing data — a CSV or XLSX from any system — for a secure, white‑glove review. Column mapping is AI‑assisted and runs locally; customer identifiers are anonymised before any model sees them. FinArrow normalises FX, expands annual contracts, and computes every metric deterministically, and a human reviews every figure before delivery. The AI‑written narrative is labelled separately and never overrides a deterministic finding — the final call is yours.
The buyer is the victim of a broken DD process, not the architect of it. FinArrow exists so that the next IC memo cites a number you can defend in the same language six months from now.
No imputation. No silent defaults. No rounding of cohort windows. The four figures below describe the entire surface area of what FinArrow promises — and what it refuses to do.
Every default applied during a run is written to the assumptions log on the report’s final page. If you didn’t set it, the report tells you what was set on your behalf — and the exact setting that produced it.
