You have a number you call MRR. You trust it, because it comes from Stripe or your billing tool. Then you raise, and someone across the table recomputes it. The two numbers do not match. That gap is where deals slow down.
MRR is not one thing. It is a definition. Most teams never write theirs down, so it drifts. Here are the usual places it goes wrong.
Annual deals counted as one month
A founder signs a $12,000 annual deal. The tool records $12,000 in the month it was paid. Now one month looks huge and the next eleven look flat. Spread over the year, that deal is $1,000 of MRR. Get this wrong and both your growth rate and your churn look fake.
One-time fees mixed into recurring
Setup fees, overages, and services are real revenue. They are not recurring. When they land in MRR, your recurring line moves with things that will not repeat. Investors strip these out. You should too.
Trials and failed payments counted as active
A trial is not paying you yet. A past-due account stopped paying. If either sits in your active count, your MRR and your customer count are both too high. Define “active and paying,” then apply it the same way every month.
Gross and net churn used as if they are the same
Gross churn is what you lost. Net churn nets in expansion from the customers who stayed. They answer different questions. Report one and call it the other, and you hide either a retention problem or a growth story.
What to do
Write down one definition for each metric. Apply it the same way every month. Then your number holds up when someone checks it, because you already did the check.
