The short answer: Bookings vs billings vs revenue vs cash is a question of timing. Bookings record signed contract value, billings record invoices issued, revenue records performance under ASC 606, and cash records money collected. In the illustrative quarter below, $2,640,000 of bookings becomes only $1,128,000 of cash.
- Three bridges connect the four numbers: the billing schedule, the change in deferred revenue and contract assets, and the change in accounts receivable.
- Bookings and ARR are company-defined operating metrics; GAAP does not define either one.
- Remaining performance obligations (RPO) under ASC 606 are the closest GAAP anchor for contracted backlog.
- A board deck should lead with recognized revenue and cash, then reconcile bookings and ARR to them on one page.

Every diligence team and most board members eventually ask the same question. Why do bookings, billings, revenue, and cash produce four different totals for the same quarter? A founder who cannot walk the bridge between them loses credibility quickly, even when every figure is correct.
This guide defines each measure, maps the three accounting bridges between them, and reconciles a single SaaS quarter end to end. It closes with guidance on which figure belongs at the top of a board deck.
Bookings vs billings vs revenue vs cash: what does each number measure?
Each number captures a different event in the life of one customer contract. Bookings mark the signature, billings mark the invoice, revenue marks delivery, and cash marks payment.
The events rarely share a calendar. A three-year subscription signed on September 28 counts fully as a September booking. It may produce one annual invoice, three days of revenue, and no cash at all before the quarter closes.
| Measure | Triggering event | Where it lives | Defined by GAAP? |
|---|---|---|---|
| Bookings | Customer signs a contract | CRM or contract register | No; each company sets its own definition |
| Billings | Company issues an invoice | Billing system and accounts receivable | No; usually derived as revenue plus the change in deferred revenue |
| Recognized revenue | Company satisfies a performance obligation | Income statement | Yes; ASC 606 |
| Cash collected | Customer payment clears the bank | Bank statement and cash flow statement | Yes; presented under ASC 230 |
How do bookings become billings?
Bookings become billings according to the invoicing schedule written into each contract. Any signed value not yet invoiced sits in backlog, which most companies track outside the general ledger.
A multi-year deal billed annually illustrates the gap. A $1,080,000 three-year contract books in full on signature, yet it bills only $360,000 per year. The remaining $720,000 waits in backlog until each anniversary invoice.
ASC 606 supplies the nearest GAAP measure of that backlog. Paragraph 606-10-50-13 of FASB’s Accounting Standards Update 2014-09 requires disclosure of “the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period.” Practitioners call this figure remaining performance obligations.
Private companies have a choice. Paragraph 606-10-50-16 lets an entity other than a public business entity elect not to provide that disclosure. Investors still request a backlog schedule in diligence, so the calculation should exist regardless.
Why does billed revenue differ from recognized revenue?
Invoices follow the contract’s payment terms, while revenue follows delivery. Two balance sheet accounts absorb the difference: deferred revenue and contract assets.
Deferred revenue grows when a company invoices ahead of delivery, as with an annual subscription billed upfront. Contract assets grow in the opposite case, when work is delivered before the company has the right to invoice.
The standard defines a contract asset as “an entity’s right to consideration in exchange for goods or services that the entity has transferred to a customer.” It separates that from a receivable, which is “an entity’s right to consideration that is unconditional.” Many ledgers label contract assets as unbilled receivables, and implementation milestones are a frequent source.
The bridge reduces to one line. Recognized revenue equals billings, minus the increase in deferred revenue, plus the increase in contract assets.
How does recognized revenue turn into cash?
Revenue turns into cash only after the customer pays the invoice. The gap between billings and collections appears as the change in accounts receivable.
Cash collected equals billings minus the increase in receivables. Net-60 terms, a slow enterprise procurement desk, or a disputed invoice each widen that gap. Our guide to accounts receivable for startups covers collection terms in detail, and the companion post on cash flow vs. revenue analyzes the monthly profit-to-cash view.
What does a four-way reconciliation look like for one quarter?
The illustrative company below sells B2B software and closes its books in QuickBooks Online. It reports the third quarter of 2026, July through September, with every bridge item taken from its balance sheet.
| Q3 2026 bridge | Amount | Running total |
|---|---|---|
| Bookings (contract value signed) | $2,640,000 | $2,640,000 |
| Less: booked value scheduled to bill in later periods | ($1,610,000) | $1,030,000 |
| Plus: invoices on contracts booked in earlier quarters | $385,000 | $1,415,000 |
| Billings | $1,415,000 | |
| Less: increase in deferred revenue | ($236,000) | $1,179,000 |
| Plus: increase in contract assets | $42,000 | $1,221,000 |
| Recognized revenue | $1,221,000 | |
| Add back: increase in deferred revenue | $236,000 | $1,457,000 |
| Less: increase in contract assets | ($42,000) | $1,415,000 |
| Less: increase in accounts receivable | ($287,000) | $1,128,000 |
| Cash collected | $1,128,000 |
What does the reconciliation reveal?
Each total is correct, and each answers a different question. The arithmetic below uses only figures from the table.
- Conversion. Revenue of $1,221,000 equals 46.2% of bookings. Cash of $1,128,000 equals 42.7% of bookings and 79.7% of billings.
- Total spread. $2,640,000 − $1,128,000 = $1,512,000 between the headline booking figure and the bank.
- Check figure. $1,221,000 + $236,000 − $42,000 − $287,000 = $1,128,000, so the revenue path and the billings path agree.
Contracted backlog tells the forward story. Deferred revenue closes at $1,416,000 and unbilled backlog at $2,950,000. After removing $42,000 of work already performed, remaining performance obligations total roughly $4,324,000.
Is ARR a GAAP metric?
No. Annual recurring revenue is a company-defined operating metric, and GAAP does not prescribe how to calculate it. Two companies can report different ARR from identical contracts.
In the example, quarterly subscription revenue of $1,141,000 annualizes to $4,564,000. Reported ARR is $4,620,000, because contracts starting October 1 count toward ARR before they produce revenue. The $80,000 of implementation revenue stays out of ARR entirely.
The SEC addressed metrics of this kind in Release No. 33-10751, issued January 30, 2020. For any key performance indicator, the Commission generally expects “a clear definition of the metric and how it is calculated.” It also expects a statement on “how management uses the metric in managing or monitoring the performance of the business.” That guidance addresses SEC filers, yet it sets a sound standard for private board decks. Our MRR and ARR waterfall guide shows how to tie ARR back to the books.
Which number should a board deck lead with?
Lead with recognized revenue and cash collected, because both tie to reviewed financial statements. Then present bookings, ARR, and RPO on the same page, each with a written definition and a bridge to revenue.
That order protects credibility. A board that sees bookings first and revenue second will ask why the second number is 54% smaller. A board that sees the reconciliation will instead ask about backlog timing and collections.

Frequently asked questions
Why does recognized revenue not equal cash flow?
Recognized revenue follows delivery under ASC 606, while cash follows customer payment. Invoices issued ahead of delivery, work delivered before invoicing, and unpaid receivables all separate the two. In the illustrative quarter, $1,221,000 of revenue produced $1,128,000 of cash.
How does revenue recognition affect the cash flow statement?
Revenue recognition sets net income, which is the starting point of the indirect cash flow statement. Operating activities then adjust for changes in receivables, contract assets, and deferred revenue, converting revenue recognized into cash actually collected.
What is the difference between billings and revenue?
Billings are the invoices a company issues in a period, and revenue is the value it earns by delivering service. Billings minus the increase in deferred revenue, plus the increase in contract assets, equals recognized revenue for the period.
Is ARR a GAAP metric?
No. ARR is a company-defined operating metric, not a measure defined under GAAP. SEC guidance from January 2020 expects companies filing with the SEC that present such metrics to give a clear definition and explain how management uses them.
How do changes in deferred revenue show up in cash flow?
An increase in deferred revenue is added back to net income in operating activities, because cash arrived before revenue was earned. A decrease is subtracted, because the period recognized revenue from cash collected in an earlier period.
Which number should a board deck lead with?
Recognized revenue and cash collected, since both tie to the financial statements. Bookings, ARR, and remaining performance obligations follow on the same page, each with a stated definition and a reconciliation back to revenue.
