Revenue measures earned sales, while cash flow measures receipts and payments. Reconcile the same month's sales, receivables, customer advances and bank movements with a worked US company example.
Cash flow vs revenue is a comparison of cash movements with earned sales. Revenue measures goods or services provided during the reporting period; cash flow measures when money enters and leaves the business, so a strong sales month can still end with less cash.
| Measure | Question it answers | Main source | Important exclusion |
|---|---|---|---|
| Revenue | What sales did the company earn this period? | Revenue ledger and approved recognition schedules | Customer payments for unsatisfied future delivery |
| Customer receipts | What cash did customers pay this period? | Cash application report and reconciled bank detail | Borrowing and owner funding |
| Operating cash flow | What cash did operations generate or use? | Operating receipts and payments, or an indirect reconciliation | Equipment purchases and financing movements |
| Net cash change | How much did the cash balance change? | All classified cash movements | Transfers between accounts within the same cash total |
Under ASC 606, revenue is recognized when or as the company satisfies a performance obligation by transferring the promised good or service to the customer. The standard's control guidance, reproduced here, explains that principle; the invoice date or bank receipt alone does not settle it.
Cash flow also differs from profit. The SEC's financial statement guide explains the distinction and separates cash flows into operating, investing and financing activities. For the P&L comparison, see revenue vs profit.
Take a revenue ledger for the month, opening and closing trade receivables, the customer advance schedule, and customer cash applications. Add a reconciled cash receipts and payments export for the same legal entities and dates. Retain document identifiers so cash applications can be traced to the invoices or advances they settle.
Use the same currency and cutoff throughout. A credit invoice belongs in the revenue and receivables records under the approved accounting treatment; the subsequent payment belongs in the bank and cash application records on its receipt date. Those are related records, not duplicate sales.
The worked example below excludes sales taxes, foreign exchange, write-offs, credit memos, contract assets and other noncash receivable movements. Those items need their own lines in a real reconciliation. Starting with an explicit boundary makes an unexplained difference easier to investigate.
Consider a fictional US business services company in September 2026. All work described as delivered below satisfies the relevant performance obligations during September. Amounts are USD and exact; no rounding is needed.
| Event | September revenue (USD) | September customer cash receipts (USD) |
|---|---|---|
| Services delivered and paid immediately | 200,000 | 200,000 |
| Services delivered and invoiced on credit | 300,000 | 0 |
| Collections on credit invoices, including earlier periods | 0 | 270,000 |
| Customer advances for future services | 0 | 60,000 |
| Services delivered against earlier customer advances | 20,000 | 0 |
| Total | 520,000 | 530,000 |
Revenue is $200,000 + $300,000 + $20,000 = $520,000. Customer receipts are $200,000 + $270,000 + $60,000 = $530,000. Neither total is operating cash flow yet, because the company also pays its operating costs.
The difference is explained by receivables and customer advances:
| Balance reconciliation | Opening balance (USD) | Additions (USD) | Reductions (USD) | Closing balance (USD) | Increase (USD) |
|---|---|---|---|---|---|
| Trade receivables | 120,000 | 300,000 credit sales | 270,000 collections | 150,000 | 30,000 |
| Customer advances | 40,000 | 60,000 advance receipts | 20,000 revenue earned | 80,000 | 40,000 |
The receivables check is $120,000 + $300,000 − $270,000 = $150,000. The advance check is $40,000 + $60,000 − $20,000 = $80,000. Both closing balances must match the relevant ledger accounts, and the cash amounts must match the cash application report.
For this defined example:
Customer receipts = Revenue − Increase in receivables + Increase in customer advances
$520,000 − $30,000 + $40,000 = $530,000
An increase in receivables means some earned revenue has not turned into cash. An increase in advances means customers supplied cash for work that has not yet become revenue. This is a revenue-to-receipts bridge, not the indirect cash flow statement, which ordinarily starts from net income and adjusts other balances too.
For a collection-speed measure, days sales outstanding uses the credit-sales and receivables records. It answers a related question without replacing this dollar reconciliation.
The company's bank detail also contains these operating payments. Assume these are all of its operating cash movements for the example; supplier payments can settle earlier bills as well as current purchases.
| Operating cash item | Inflow (USD) | Outflow (USD) |
|---|---|---|
| Customer receipts | 530,000 | 0 |
| Supplier payments | 0 | 330,000 |
| Payroll, rent and other operating payments | 0 | 150,000 |
| Taxes and interest paid | 0 | 20,000 |
| Total | 530,000 | 500,000 |
| Net operating cash flow | 30,000 |
Operating payments total $330,000 + $150,000 + $20,000 = $500,000. Operating cash flow is $530,000 minus $500,000 = $30,000. The revenue figure remains $520,000; subtracting cash payments from revenue would mix two timing bases.
Now complete the bank movement:
| Cash reconciliation | Amount (USD) |
|---|---|
| Opening cash | 90,000 |
| Operating cash flow | 30,000 |
| Equipment purchases: investing outflow | -100,000 |
| Loan proceeds: financing inflow | 50,000 |
| Closing cash | 70,000 |
| Net change in cash | -20,000 |
The check is $90,000 + $30,000 − $100,000 + $50,000 = $70,000. Revenue is positive and operations generate cash, yet the cash balance falls because equipment spending exceeds the combined operating inflow and new borrowing.
Hold revenue, advances, payments, equipment purchases and borrowing unchanged. Suppose credit-invoice collections are $230,000 instead of $270,000, a $40,000 reduction.
Customer receipts become $200,000 + $230,000 + $60,000 = $490,000. Closing receivables rise to $120,000 + $300,000 − $230,000 = $190,000. Operating cash flow becomes $490,000 minus $500,000 = -$10,000 even though revenue remains $520,000.
The credit team should investigate payment timing; the sales result alone will not reveal it. Treasury can use the collection assumptions in a cash flow forecast, while finance checks whether the delay is temporary or persistent. A lender-oriented UCA cash flow analysis takes a different view of cash generation and debt service.

Yes. More credit sales can increase revenue while customers take longer to pay. Higher inventory purchases or supplier payments can also reduce operating cash flow. Review receivables and operating payments alongside sales, then separate equipment purchases and financing from the operating result.
Receiving a deposit does not by itself establish revenue. A payment for future delivery generally creates a customer advance or contract liability until the relevant performance obligation is satisfied. The receipt increases cash now; the accounting policy determines when the company recognizes the related revenue.
No. Customer receipts are one source of operating cash inflow. Operating cash flow also reflects operating payments and any other relevant operating cash movements. A company can collect substantial customer cash and still use cash overall if its operating payments exceed those inflows.
No. Borrowing increases cash and creates a financing obligation. It belongs in the financing cash flow review rather than the sales total. Keep loan proceeds separate from customer receipts so funding does not disguise a shortfall in cash generated by operations.
