Monthly Recurring Revenue MRR
The predictable subscription revenue a company can count on in a given month, normalized so an annual plan is spread across the twelve months it covers.
The fork, why two teams get different numbers
"MRR" is a billing artifact, not a GAAP number, so every team draws its own boundary. Finance/RevOps run NORMALIZED (committed) MRR: every active recurring subscription converted to a monthly amount, one-time fees and usage overages excluded. The billing platform's dashboard often reports BILLED MRR: whatever hit an invoice this month, which spikes when annual plans are charged up front and collapses the months between. A usage-heavy vendor's product team quietly folds consumption/overage into MRR to make the line look bigger, while the auditors treat that portion as non-recurring. The same subscriber base yields three different MRR numbers depending on which room you ask.
