Total Customers
Definition
Count of active paying customer logos at the end of the period. "Active" means the customer has a live paid subscription or contract on the reporting date — not trial, not cancelled, not zero-revenue. The board reads this alongside ARR to triangulate whether growth is logo-driven (more customers at similar ACV) or expansion-driven (existing customers paying more). Common pitfall: definitions of "customer" drift over time as the company sells to subsidiaries, parent accounts, or self-serve users — settle the counting unit (parent vs. account vs. seat) and document it in `customer_definition_note` so cross-period comparisons stay honest.
Why it matters
The denominator beneath every retention, churn, and concentration metric — and the simplest read on whether the company is winning new logos at the headline level. Boards use it to disambiguate logo-led vs. ARR-led growth.
How it's calculated
Count of customer logos with an active paid subscription/contract on the reporting date. Excludes trials, paused accounts, and $0 contracts. Counting unit (parent vs. account vs. seat) must be documented and held constant period-over-period. How to interpret it
Net change = new logos − churned logos; pair with `customers_churned` and ARR delta. Stage-typical absolute counts vary so widely (B2B enterprise vs. SMB SaaS) that an absolute count is industry folk-wisdom, not citation-grade — compare instead to the company's own trailing 4-quarter trend. A definitional change to "customer" must be flagged on the chart, not absorbed silently.

Related KPIs
Count of customer logos that ended their subscription/contract during the period. Includes voluntary cancellations and non-renewals. Some companies separately track downgrade-to-zero as churn — be explicit about whether downgrades that drop ARR to $0 count as churn (typical: yes) vs. material contraction that keeps ARR > 0 (typical: tracked under contraction, not churn). The board reads this as the raw count behind `logo_churn_rate`; the percentage tells you the rate, the absolute count tells you the volume of CS pain. Common pitfall: counting customers that re-activate (sometimes called "boomerang" or resurrection) — settle the rule (typical: count each cancellation event, do not net resurrection).
Share of customer logos retained from the prior period, counted by logo (not by revenue). Per the SaaS Metrics Standards Board (SMSB) Logo Retention standard: numerator is logos present at both period start and period end; denominator is logos present at period start. New logos acquired during the period are excluded from both. The board reads this as a "stickiness" signal independent of ACV: high logo retention with weak NRR points to flat/contracting expansion; weak logo retention with strong NRR points to high concentration risk. Common pitfall: conflating logo retention with revenue retention — they answer different questions and routinely diverge.
Share of customer logos lost during the period — the inverse of logo retention. Numerator is logos that churned during the period; denominator is logos present at period start. Per the KBCM/Sapphire Private SaaS Company Survey definition (treated as the de-facto private-SaaS reporting convention). The board reads this as the simplest churn signal — independent of revenue-weighting. Common pitfall: confusing annualized vs. period-rate (monthly churn × 12 ≠ annualized churn for a compounding base) — be explicit about the time window and annualization method.
Share of total ARR contributed by the top N customers — typically top 5 or top 10. Measures revenue concentration risk: a high concentration means losing one big customer would materially dent ARR. The board reads this alongside `arr_at_risk` and the customer list to gauge how much of the company's future is tied to a handful of accounts. Common pitfall: hiding parent-account aggregation — if three "customers" are subsidiaries of the same parent, true concentration is higher than the count-by-logo view shows; settle parent-rollup rules and document them in `customer_definition_note`.
Annual Recurring Revenue — the value of all recurring subscription revenue normalized to a one-year run-rate as of the period close. The headline operating metric for a subscription business; every growth and efficiency ratio (NRR, GRR, magic number, CAC payback, Rule of 40) is calibrated against it. Excludes one-time fees, professional services, and non-contractual usage. Common pitfall: confusing ARR (contracted recurring) with revenue (recognized) or with CARR (contracted incl. not-yet-live) — the SMSB standard draws sharp lines between them, and boards expect the same discipline. The KpiVarianceTable widget surfaces forecast / actual / variance / status / future-forecast columns against the same field.
