Unpaid Invoices Cost Small Business $17,500 [2026 Data]

US small businesses carrying unpaid invoices are owed an average of $17,500, according to Intuit QuickBooks’s 2025 Small Business Late Payments Report, and the number is moving the wrong way. The 2026 wave of the same survey puts the average at $17,700, with a sharply higher share of businesses now affected. Unpaid invoices are not just a cash flow inconvenience: businesses carrying them lean harder on credit cards and loans, delay their own bills, and increasingly pay fees just to access money they already earned.

How much are small businesses owed in unpaid invoices?

56% of US small businesses report being owed money from unpaid invoices at any given time, and the average amount outstanding across those businesses is $17,500, according to Intuit QuickBooks’s 2025 Small Business Late Payments Report, based on a January 2025 survey of 2,487 US small businesses with up to 100 employees. Nearly half, 47%, have at least one invoice overdue by 30 days or more, and aged invoices like that make up close to 10% of the average affected business’s total invoice volume. Put another way: more than half of small businesses are, at any given moment, sitting on a five-figure sum for work they have already delivered but not been paid for.

Is the amount owed getting worse in 2026?

Yes, on both measures that matter. The 2026 wave of the QuickBooks survey, drawn from a quarterly panel of roughly 5,000 small business owners with 1,305 responses collected in December 2025, puts the average amount owed at $17,700, up from $17,500 a year earlier. The bigger shift is in how many businesses are affected: 59% now report at least one invoice overdue by 30 days or more, up 12 percentage points from 47% in the 2025 wave. That is not a rounding change; it is roughly one in eight additional small businesses falling behind in a single year.

The knock-on effects are concrete, not abstract. 39% of owners in the 2026 report say a single late payment created hardship covering payroll or other bills, and 27% reported real financial strain from a missed payment under $5,000, with 12% feeling that strain from a payment under just $1,000.

What does chasing unpaid invoices cost beyond the dollar amount?

Being owed money changes how a business runs, not just what it has in the bank. Small businesses with overdue invoices report using business credit cards at a 54% rate, lines of credit at 31%, and loans at 21%, compared with 46%, 21%, and 11% respectively among businesses with no overdue invoices, per QuickBooks’s 2025 report. The 2026 wave adds a fee-based cost on top: 59% of owners paid extra fees for instant-transfer or fast-deposit services in 2025 just to access money already owed to them, and 15% now use those paid services routinely rather than as a one-off. There is a time cost too, though the best-documented figure comes from Australia rather than the US: GoCardless’s 2025 Pursuing Payments report, a YouGov survey of 500 Australian small and medium business owners, found 63% spend time chasing late payments, averaging 1.5 hours a week, more than 78 hours, or roughly two full working weeks, a year.

Do payment terms change whether an invoice gets paid at all?

The 2026 QuickBooks data says yes, and by a wide margin. Businesses that require payment upfront, before work begins or on delivery, report zero overdue invoices 64% of the time. Businesses using standard net 30 terms report an overdue invoice 55% of the time. That is close to a reversal: upfront-payment businesses are mostly overdue-free, while net-30 businesses are overdue more often than not.

Requires payment upfront	Zero overdue invoices 64% of the time
Standard net 30 terms	Overdue invoices in 55% of cases

Are freelancers affected differently than small businesses with staff?

The dollar figure is smaller, but the relative damage is comparable or worse. Freelancers Union’s nonpayment research, an older but still widely cited study of freelancer income loss, found freelancers lose an average of about $6,000 a year to nonpayment and late payment, close to 13% of typical freelance income for someone working alone. Set against a small business’s $17,500, the freelancer figure looks smaller in dollars but represents a much larger bite out of one person’s total earnings, with no staff or reserves to absorb the gap. On the other side of the ledger, a smaller but real share of invoiced work never gets collected at all: roughly 4-5% of B2B credit sales in North America are written off as bad debt, gone for good, according to Atradius’s North America Payment Practices Barometer. For the broader roundup of invoicing data this post draws a narrower thread from, see Invoice Statistics 2026.

The Bottom Line

$17,500 was never a static number, and the 2026 data shows it moving up, alongside a much larger jump in how many businesses are affected at all, from 47% to 59% carrying a 30+ day overdue invoice in a single year. The same data also shows what narrows the gap: requiring payment upfront instead of net 30 terms cuts the overdue rate by roughly 20 points, and a scheduled reminder cadence and an online payment link both measurably speed up collection, as covered in more depth in this cluster’s other posts. A BillyPaid invoice includes a payable link and automated reminders by default, so a business does not have to choose between offering reasonable terms and staying off the growing side of these statistics.
