Billings
DEFINITION
Billings is the total dollar amount a subscription business invoices its customers in a given period, regardless of when that revenue will be recognized. It is a forward-looking read on demand that often signals a change in trajectory before recognized revenue does.

Billings is the total dollar amount a subscription business invoices its customers in a given period, regardless of when that revenue will be recognized. It reflects what was actually invoiced in the period, the amount that becomes accounts receivable until collected and is recognized as revenue as the service is delivered. Internally, billings are read directly from a company's invoicing records. External analysts, who can't see those invoices, often estimate it from reported financials as recognized revenue plus the change in deferred revenue, an approximation that holds when a business bills in advance but breaks down when revenue is recognized ahead of invoicing.
Billings sits between what a customer commits to buy and what the business is allowed to report as earned revenue. When an invoice goes out, the amount is booked as billings right away, but accounting rules only let the business recognize that amount as revenue as the service is delivered over the subscription term. The portion not yet earned sits on the balance sheet as deferred revenue. So billings captures invoicing activity in the period, while recognized revenue captures delivery, and deferred revenue is the bridge between the two. This is why billings tends to move ahead of the revenue line: a large annual contract signed and invoiced today shows up in billings now, but flows into recognized revenue gradually across the months that follow. In a subscription platform such as Recurly, billings, deferred revenue, and recognized revenue all trace back to the same invoicing and subscription records, so the inputs to the calculation are consistent rather than stitched together from separate systems.
Why billings matters for subscription businesses
Billings is a forward-looking read on demand. Because it reflects new and renewed commitments at the moment they are invoiced rather than the paced-out earning of those commitments, it often signals a change in trajectory before recognized revenue does. Finance and revenue operations teams watch it to gauge sales momentum, to sanity-check pipeline against what is actually being invoiced, and to anticipate the cash and revenue that will land in later periods. A quarter where billings outpaces revenue growth suggests the business is building a larger base of deferred revenue to draw down later, while billings that lag revenue can be an early warning that growth is slowing.
For an operator, the value of a subscription management and billing platform such as Recurly is that the period's invoiced total reflects the same events that drive the revenue and deferred revenue lines, because billing schedules, proration, and renewals are handled in one place. The same recognized revenue and deferred revenue balances a team already tracks are the figures used to derive billings for a period, so the number ties back to source records rather than being estimated from the outside.
How to use billings
Treat billings as a companion to recognized revenue, not a replacement for it.
Calculate billings for the period as recognized revenue plus the change in deferred revenue.
Compare period-over-period billings growth against recognized revenue growth to see whether the business is accelerating or decelerating.
Segment billings by new business, renewals, and expansion so a spike or dip can be traced to a specific driver.
Watch for timing effects. Multi-year deals invoiced up front, annual-to-monthly plan shifts, and seasonal renewal clusters can all swing a single period's billings without reflecting a change in underlying demand.
Reconcile billings back to invoices issued so the figure ties to source records rather than to a derived estimate alone.
How to calculate billings
Billings for a period is recognized revenue plus the change in deferred revenue across that period:
Billings = Recognized revenue + Change in deferred revenue
Change in deferred revenue = Ending deferred revenue - Beginning deferred revenue
To work through it:
Start with recognized revenue for the period.
Take the deferred revenue balance at the end of the period.
Subtract the deferred revenue balance at the start of the period to get the change in deferred revenue.
Add that change to recognized revenue. The result is billings for the period.
Worked example (illustrative figures):
Recognized revenue for the period: 1,000,000
Ending deferred revenue: 600,000
Beginning deferred revenue: 400,000
Change in deferred revenue = 600,000 - 400,000 = 200,000
Billings = 1,000,000 + 200,000 = 1,200,000
In words: if a business recognizes revenue as it delivers service and its deferred revenue balance grew over the period, billings is higher than recognized revenue by exactly the amount deferred revenue increased. If the deferred balance shrank, billings is lower than recognized revenue by the amount it fell.
Internally, billings is read directly from a company's invoicing records. External analysts, who cannot see those invoices, often estimate it from reported financials as recognized revenue plus the change in deferred revenue, an approximation that holds when a business bills in advance but breaks down when revenue is recognized ahead of invoicing.
Billings vs revenue vs bookings
These three figures describe the same customer relationship at different stages, and they are easy to conflate.
Bookings is the total value a customer commits to when a contract is signed, before any invoice is issued. It reflects what sales has closed.
Billings is the amount actually invoiced in a period. A signed contract can be booked now but billed on a schedule, so bookings and billings can differ in both size and timing.
Revenue, in the sense of recognized revenue, is the portion the business is allowed to report as earned as it delivers the service over time.
A single annual deal illustrates the difference: the full contract value is a booking when signed, becomes billings when the annual invoice is issued, and is recognized as revenue in equal parts across the twelve months of service.
Benefits and examples
Tracking billings gives operators an earlier and more complete picture of commercial health than recognized revenue alone.
It surfaces momentum. A run of quarters where billings grows faster than revenue points to a widening deferred revenue balance that will support future recognized revenue.
It sharpens forecasting. Because billings leads revenue in a subscription model, a reliable billings trend feeds a more confident revenue forecast.
It exposes timing distortions. When a customer moves from monthly to annual billing, recognized revenue is unchanged but billings jumps in the period the annual invoice is issued, which is worth calling out so the number is read correctly.
It ties commercial and finance views together. Sales sees bookings, finance sees recognized revenue, and billings is the invoiced figure that connects the two.
Frequently asked questions
Is billings the same as revenue? No. Billings is what a business invoices in a period, while revenue in the accounting sense is what it recognizes as earned as it delivers the service. For a subscription paid in advance, billings usually comes first and revenue is recognized gradually afterward, so the two figures rarely match in any single period.
How do you calculate billings? The common formula is recognized revenue for the period plus the change in deferred revenue over that period. If deferred revenue grew, add the increase to recognized revenue; if it shrank, subtract the decrease. This works because anything invoiced but not yet earned sits in deferred revenue until it is recognized.
Why is billings considered a leading indicator? Because it captures new and renewed commitments at the moment they are invoiced, rather than the slow recognition of those commitments over the service term. A shift in demand tends to show up in billings before it reaches the recognized revenue line, which makes billings useful for spotting acceleration or slowdown early.
What is the difference between billings and bookings? Bookings is the value a customer commits to when a contract is signed. Billings is the amount actually invoiced, which may happen later and on a schedule. A multi-year contract can be a large booking today but produce billings spread across several invoice dates.
Can billings go down while revenue goes up? Yes. If a business invoices less in a period than it did previously but is still recognizing revenue from contracts invoiced earlier, recognized revenue can rise while billings falls. This is often an early sign that growth in new and renewed commitments is slowing.
