The exclusion test
Ask one question of every line on the invoice. If nobody signs anything new, will this same amount bill again next year? If the answer is no, it does not belong in ARR.
That test removes:
- Implementation, onboarding, and data migration fees - Professional services and custom development billed by project or by hour - Training, certification, and paid support incidents sold separately - Hardware, resold third-party licenses, and pass-through costs - Overage charges above a contracted commitment
It keeps subscription fees, contracted seat and platform charges, and support tiers a customer pays for as a standing part of the subscription.
Where usage revenue gets messy
Usage-based pricing is the case that trips teams up. A customer with no committed minimum carries no recurring obligation, so none of their usage revenue is ARR under the strict definition. A customer with a contracted floor of $60,000 a year who consumes $85,000 contributes $60,000 to ARR. The extra $25,000 is real revenue and belongs in billings and recognized revenue reporting. It is variable, and it fails the exclusion test.Recurring professional services are the other edge case. A managed service billed monthly under an evergreen contract recurs and counts. A statement of work that ends in March does not.
What overstating ARR costs you
An inflated ARR base corrupts every metric derived from it. Retention gets measured against a denominator that includes revenue no customer ever intended to renew, so net revenue retention reads better than the business is performing. Quota and capacity plans get built on a growth rate that includes services revenue the sales team was never compensated to sell. Then the services revenue does not repeat the following year, and it surfaces as churn that never happened.
Report ARR strictly and report services revenue as its own line. Both numbers matter and they answer different questions. A revenue forecast that mixes them cannot tell you which part of next year is already contracted and which part still has to be sold, which is the only question the forecast exists to answer.
Frequently Asked Questions
Does ARR include implementation fees?
No. Implementation, onboarding, and data migration fees are billed once and do not repeat without a new agreement, so they fall outside annual recurring revenue. They belong in bookings, billings, and recognized revenue reporting, reported as a separate services line.
Is usage revenue part of ARR?
Only the contracted minimum. A customer with a $60,000 annual floor who consumes $85,000 contributes $60,000 to ARR. The $25,000 above the floor is real revenue with no contractual obligation behind it, so it is reported outside ARR.
Do professional services ever count toward ARR?
Yes, when they are sold as a recurring subscription. A managed service billed monthly under an evergreen contract recurs and counts. A statement of work with a fixed end date does not, no matter how large it is.
What goes wrong if you include one-time fees in ARR?
Retention rates get measured against a denominator containing revenue no customer ever intended to renew, so retention reads better than the business performs. The following year the services revenue does not repeat and shows up as churn that never happened.
