Monthly recurring revenue, or MRR, is the predictable subscription revenue a business earns in a month, counted as a rate of revenue rather than as cash received. New sales, expansion, downgrades and churn move it. Sales plans use it as a commission basis by paying a multiple of the MRR a rep adds.
Most of the trouble with MRR starts with treating it as an amount of money that arrived. It is a run rate. A customer who prepays $60,000 for twelve months contributes $5,000 of MRR every month of that year, and the month the cash landed is not special. Read the bank statement instead of the contract and you will report a spike that never happened, then pay commission on it.
The movement is the useful part, and it has four components that pull in different directions. New business is MRR from customers who had none. Expansion is more MRR from customers who already had some, through seats, tiers or usage. Contraction is a downgrade. Churn is a departure. The board sees the net of all four. Sales reps are typically paid on only the first two, because they cannot be held responsible for a renewal decision made eight months after they left the account.
That gap is worth naming out loud when a plan is designed, because commissionable MRR and net new MRR are almost never the same number, and finance models built on the second will under-budget the first. The other structural point about MRR as a basis: it pays the same for a customer who lasts one month as for one who lasts five years. Any plan paying a multiple of new MRR needs a retention window behind it, or it is simply paying for signatures.
A subscription business opens the month at $412,000 of MRR. Four things happen to it. The comp plan pays reps a multiple of one times the MRR they add through new business and expansion.
The company grew by $29,000 a month. Payroll owes $49,500. Both figures are right, and a plan that never writes down which one it means will produce a budget variance every single period.
A customer signs for a year and pays the whole $60,000 upfront. The invoice says $60,000, the CRM opportunity amount says $60,000, and the MRR that deal represents is $5,000. If the commission plan says it pays a one times multiple of new MRR and the data pipeline hands the engine the deal amount, the rep is paid $60,000 rather than $5,000 and nobody notices until the accrual is reviewed. Define the MRR field at the source, derive it from term length, and never let a plan read whichever revenue number happens to be nearest.
Commish pays monthly recurring revenue (mrr) the way your plan describes it, shows the arithmetic on every line, and traces each payment back to the deal that earned it.
