Billings

Billings are the total amounts you invoice customers during a period. Unlike bookings, which are recorded when a contract is signed, a billing happens when you actually issue an invoice — so billings are the closest of the three milestones to real cash, and a leading indicator of the money about to arrive.

How billings are calculated

Billings sum every invoice issued in the period. A common way to derive them from the financials is to add the change in deferred revenue back to recognized revenue.

For example, a customer on an annual plan is invoiced $12,000 upfront in January. That full $12,000 is billed in January. Only $1,000 becomes recognized revenue that month; the remaining $11,000 sits as deferred revenue and is billed-but-not-yet-earned.

Why billings matter

• Cash timing — billings predict cash inflow far better than revenue, which is spread over the delivery period.
• Sales-to-cash bridge — comparing billings to bookings shows how quickly signed deals convert to invoices.
• Upfront-heavy models — annual-prepaid businesses can have billings well above recognized revenue in a given month, which is healthy, not a red flag.

Billings vs bookings vs revenue

The same deal moves through three stages: it's booked when signed, billed when invoiced, and recognized as revenue when the service is delivered. Bookings and billings are non-GAAP operating metrics; recognized revenue is the GAAP figure on the P&L. Watching all three prevents a business from looking healthier — or weaker — than it is at any single stage.
