Cash received, revenue recognised and annual recurring revenue are three different numbers describing the same contract. Treating them as one flatters the business until someone examines it.
A subscription business collects in advance and earns over time. That single fact produces the most common reporting error in the sector: treating the collection as revenue.
An annual contract billed in January is cash in January and revenue across twelve months. Recognised on invoicing, January looks extraordinary and the following eleven months look like decline, while the cost of actually serving the customer lands throughout.
Four numbers, not one
- Bookings
What the customer committed to. A sales measure, not a financial one.
- Billings
What was invoiced in the period. Depends on billing terms, not on delivery.
- Cash
What was collected. Depends on payment behaviour.
- Revenue
What was earned by delivering service in the period. The only one that belongs in the P&L.
All four are legitimate and all four are useful. Reported as one, they mislead — and which one gets quoted tends to depend on which is largest.
Deferred revenue is a liability, and it matters
The portion billed but not yet earned is an obligation to deliver service. It belongs on the balance sheet, and it needs tracking and reconciling every close.
A business that treats collections as revenue overstates performance and understates its obligations simultaneously. A diligence process finds this immediately, and it is a poor thing to be explaining then — not because it is dishonest, but because it makes every other number look unexamined.
The cash is in the bank and it is not yet yours. Both are true at once, and the accounts have to say so.
The ARR bridge
Annual recurring revenue is a useful operating measure, but only when it reconciles to something. The way to keep it honest is a bridge showing every movement between opening and closing:
- Opening ARR.
- New — genuinely new customers.
- Expansion — existing customers paying more.
- Contraction — existing customers paying less.
- Churn — customers lost.
- Closing ARR.
Each movement explained, and the total reconciling to recognised revenue on a stated basis. Without the bridge, ARR is a number that can be quoted but not defended, and investors know it.
Gross margin needs the cost of revenue
Cloud and infrastructure cost scales with usage rather than with customer count, and support cost scales with something else again. Left in one line, gross margin is a plausible-looking figure nobody can decompose.
Attributing cost of revenue properly is what makes unit economics real — and acquisition cost measured against retained revenue rather than against bookings is the other half of the same discipline.
