Billings is revenue plus the change in deferred revenue
Billings captures the full commercial volume of a period: it combines recognized revenue with amounts invoiced but not yet earned, giving a faster-moving signal of business momentum than GAAP revenue alone. In SaaS, where annual and multi-year contracts are common, revenue recognition can significantly lag the invoice date.The accounting relationship is:
Billings = Revenue + Change in Deferred RevenueIf a company invoices a customer $120,000 for an annual contract in January, it records $10,000 in revenue each month. But it records the full $120,000 as a billing in January. The remaining $110,000 sits in deferred revenue and flows into revenue over the subsequent eleven months.
Why billings leads revenue
Recognized revenue is constrained by the service delivery period. A contract signed in December for service starting in January produces no revenue in December but does produce a billing. Because revenue follows the billing by the length of the recognition period, billings growth in one quarter predicts revenue growth in future quarters.
| Metric | What It Captures | Timing |
|---|---|---|
| Billings | Total invoiced amount | At invoice date |
| Revenue | Earned portion of invoiced amount | Over service period |
| ARR | Annualized run rate of active contracts | Current snapshot |
Billings as a CFO and investor metric
CFOs use billings to project cash collections. Annual contracts invoiced upfront convert to cash within days or weeks of billing. Multi-year contracts billed annually are more complex but follow a predictable schedule once mapped.
Investors use billings growth as a proxy for demand when revenue growth is temporarily suppressed by timing factors: transitioning from monthly to annual billing, shifting to back-loaded deal structures, or completing a large cohort of renewals in a single quarter.
Billings can also be manipulated by pulling forward deals or offering extended payment terms, which inflates a single quarter at the expense of future periods. Analysts track the billings-to-revenue ratio over time to detect these patterns.

Billings sits closest to cash and commercial activity in the reporting stack. For the ARR view of contracted recurring revenue, see annual recurring revenue. For the booked-vs-billed distinction, see bookings vs. revenue. For period-over-period growth, see net new ARR.
Frequently Asked Questions
What are billings in SaaS?
Billings is the total dollar amount invoiced to customers in a given period. It equals recognized revenue plus any increase in deferred revenue (or minus any decrease). Because billings includes revenue that has been invoiced but not yet recognized, it leads revenue as a growth indicator.
Why do investors focus on billings?
Revenue recognition is governed by contract terms and accounting rules, which can lag the actual commercial activity of a business. Billings is closer to cash collection and reflects the real volume of business closed and invoiced in a period. For pre-profitability SaaS companies, billings growth signals momentum before it fully appears in recognized revenue.
What is the relationship between billings and deferred revenue?
When a customer pays upfront for an annual contract, the full invoice amount is a billing, but only one month's worth is recognized as revenue each month. The rest sits in deferred revenue on the balance sheet. Billings equals revenue plus the change in deferred revenue on the balance sheet from one period to the next.
