ARR / CARR Waterfall
The ARR / CARR Waterfall report displays how recurring revenue changes over time in a waterfall-style table.
The report allows you to track starting balances, period-by-period changes, and cumulative balances for each customer within a selected date range. Recurring revenue movements are shown at the customer level across multiple reporting periods.

How the Report Works
Rillet calculates recurring revenue using contract line items that are configured to count toward MRR or ARR.
The report determines the Starting Balance for each customer at the beginning of the selected date range.
It then applies recurring revenue changes for each reporting period and calculates the cumulative balance accordingly.
Recurring revenue changes may result from:
New contracts
Contract amendments
Expansions
Contractions
Terminations
Manual overrides (when applicable)
All values are displayed according to the selected Breakdown, Status, and Type options.
