Prior-Quarter NRR
Net Revenue Retention reported in the PRIOR period — the comparison anchor for the current `customers.net_revenue_retention`. The board reads the two together to render the NRR trend on the bespoke customers retention grid. Per the SMSB NRR cohort definition, both periods must use the same closed-start-cohort methodology for the delta to be meaningful. Common pitfall: comparing an NRR computed on a different cohort window across the two periods. — Customers KPI, I'mBoard-authored (editorial tier).

Definition
Net Revenue Retention reported in the PRIOR period — the comparison anchor for the current customers.net_revenue_retention. The board reads the two together to render the NRR trend on the bespoke customers retention grid. Per the SMSB NRR cohort definition, both periods must use the same closed-start-cohort methodology for the delta to be meaningful. Common pitfall: comparing an NRR computed on a different cohort window across the two periods.
Formula
NRR from the prior period, on the same SMSB closed-start cohort basis as the current `customers.net_revenue_retention`. nrrTrend = net_revenue_retention − prior_quarter_nrr (in points).Why it matters
Direction matters more than level for retention — a slipping NRR is an early expansion-engine warning even while still above 100%.
How to interpret
A multi-point decline with steady GRR means expansion is decelerating; pair with customers.prior_quarter_grr to separate the "keep" signal from the "expand" signal.

Prior-Quarter GRR
Gross Revenue Retention reported in the PRIOR period — the comparison anchor for the current `customers.gross_revenue_retention`. The board reads the two together to render the GRR trend on the bespoke customers retention grid. Per the SMSB GRR definition (excludes expansion, capped at 100%), both periods must use the same cohort basis for the delta to mean anything. Common pitfall: reading a GRR trend without the matching NRR trend — the gap between them is the expansion signal. — Customers KPI, I'mBoard-authored (editorial tier).
Prior-Quarter Total Customers
The total active customer-logo count at the END of the prior reporting period — the opening balance for the current period's logo bridge. The board reads this so the bespoke customers card can show beginning vs. ending logos and the net change without having to re-derive the opening balance from `total_customers − new + churned`. Common pitfall: silently re-stating the prior total after a definitional change to "customer" — hold the counting unit constant or footnote the restatement. — Customers KPI, I'mBoard-authored (editorial tier).
