Short answer: bookings are the value of contracts you sign, billings are what you invoice, and revenue is what you have actually earned by delivering the service. Bookings show demand, billings drive cash, and revenue measures performance. Mixing them up is one of the fastest ways to lose credibility with investors.
One contract, three numbers
A customer signs a 12-month, $120,000 contract in January and pays annually up front.
| January | February to December | What it tells you | |
|---|---|---|---|
| Bookings | $120,000 | $0 | Demand: the value of new commitments |
| Billings | $120,000 | $0 | Cash: what you have asked customers to pay |
| Revenue | $10,000 | $10,000 per month | Performance: what you have earned so far |
If the same customer were billed monthly, billings would be $10,000 per month, matching revenue, but bookings would still be $120,000 in January.
Why each matters
- Bookings show sales momentum and future revenue. They are a leading indicator.
- Billings drive cash flow and receivables. Annual up-front billing can fund growth.
- Revenue is recognized under ASC 606 as you deliver the service and appears on your income statement.
Where deferred revenue fits
When you bill or collect before you deliver, the difference sits on the balance sheet as deferred revenue. In the example above, after January you would carry $110,000 of deferred revenue, released at $10,000 per month.
Related numbers investors ask for
- ARR or MRR: the annualized or monthly value of recurring contracts in force.
- Remaining performance obligations: contracted revenue not yet recognized.
- Net revenue retention: how revenue from existing customers grows or shrinks over time.
Frequently asked questions
Which number should I put in my pitch deck?
ARR and revenue are the most common. If you show bookings, label them clearly and explain how they convert to revenue.
Are billings the same as cash?
No. Billings are invoices. Cash arrives when customers pay, which depends on payment terms and collections.
Why is my revenue lower than my bookings?
Because revenue is recognized over the contract term, while bookings count the full contract value when it is signed.
