Closing Logos

What it measures

The number of distinct legal entities holding at least one active contract on the last day of the period, constructed as a waterfall: the opening logo balance plus new logos won minus logos lost to churn. It is the rightmost bar of the logo bridge and becomes next period's Starting Logos. Unlike a revenue waterfall, the logo waterfall has only two flows that move the count — acquisition and churn. Upsell and downsell change a logo's spend (and therefore ARPL and your revenue waterfalls) but never change the count: an active customer that downgrades is still one logo, and an existing customer that expands is still the same logo. Each organization counts exactly once regardless of how many seats, products, or contracts it holds.

Why it matters

Closing Logos is the outcome metric for customer acquisition and retention — it tells you whether your sales engine is widening the customer base faster than churn is draining it. Because it counts organizations rather than dollars, it isolates breadth of relationships from depth of spend: you can grow revenue by expanding a shrinking set of accounts, but Closing Logos exposes whether the underlying customer base is actually getting wider. Boards and investors read Closing Logos (and its movement against Starting Logos) to judge market penetration and land-and-expand health, and it is the denominator under every per-logo metric — ARPL, logo churn rate, and CAC payback all read off it.

How to read it

Read Closing Logos as a waterfall and a trend, never as a standalone snapshot. Compare it to Starting Logos to measure net motion: open at 98 and close at 105 and the period added 7 logos net — but that net can hide far larger gross flows, such as 12 new logos offset by 5 churned. Net movement disguises gross activity, so always pair Closing Logos with New Logos and Churned Logos: a flat number (130 to 130) can mask a crisis where 25 customers were won and 25 lost, leaving a completely unstable base. Rising Closing Logos with rising churn means your acquisition engine is strong but the bucket is leaking; rising revenue with flat or falling Closing Logos means you are squeezing existing accounts rather than expanding reach. Also read it against Closing Live Users — if logos grow faster than users, you are landing thin, under-deployed cohorts.

Watch-outs

• Including upsell or downsell in the count. Expansion and contraction move revenue and seats, not logos. A customer that downgrades from a 50-seat plan to a 10-seat plan is still one logo; an existing customer that expands is still the same logo. Adding upsell or downsell terms to the logo waterfall double-counts customers and breaks the bridge — only New and Churned change the count.
• Confusing the logo count with contract or user counts. A customer with 3 product contracts and 200 seats is still 1 logo. If you have 127 logos but 212 active contracts, Closing Logos is 127, not 212 — using contract or seat counts inflates the growth story and breaks every downstream per-logo metric.
• Reading the net and ignoring the component flows. A flat Closing Logos (130 to 130) can hide 25 new logos fully offset by 25 churned. Always report New and Churned Logos alongside Closing Logos so a quiet, balanced number cannot disguise an unstable base.
• Leaving churned or expired customers in the count. Apply the period-end cutoff strictly: a customer must hold an active contract on the last day of the period to be counted. If their contract ended on day 28, they are out of month-end Closing Logos even though they were active mid-month.
• Timing inconsistency. Counting logos at month-end in one period and mid-period in another introduces phantom churn. Pick a single cutoff — always actual end-of-day on the last day of the period — and hold it, so Closing Logos is comparable across periods and does not shift based on when you run the data pull.
