Overdue Invoice Recovery Rate by Age 2026: From 68.9% to 8.9% [Data]

An overdue commercial invoice is 68.9% recoverable once it hits 90 days past due, according to benchmark data tracked by the Commercial Collection Agencies of America. That number is only the midpoint of a much steeper curve: recovery odds fall to 51.3% by six months, 21.4% by one year, and just 8.9% by two years. Age is the single biggest predictor of whether an invoice ever gets paid, and the data below breaks down exactly how fast that clock runs out.

What is the recovery rate for an overdue invoice, by age?

It drops steadily, then steeply, and the shape of the curve matters more than any single number on it. Commercial Collection Agencies of America benchmark data, cited widely across the commercial collections industry, puts the probability of recovering a commercial invoice at 68.9% once it is 90 days past due.

That 68.9% figure falls to 51.3% at six months, then collapses to 21.4% at one year and 8.9% at two years past due. The pattern holds because collectability has less to do with a debtor’s actual ability to pay and more to do with attention and paperwork: a fresh invoice is competing for a customer’s current cash-flow priorities while the relationship, the paper trail, and the original context of the sale are all still intact. A two-year-old invoice has usually been forgotten, absorbed into a dispute nobody remembers the details of, or overtaken entirely by changes on the debtor’s side, including a closed account, new ownership, or bankruptcy.

How fast does write-off risk climb as an invoice ages?

Slowly at first, then all at once. Resolve, an accounts receivable platform, publishes its own analysis of write-off rates by invoice aging bucket, and the shape mirrors the collectability curve above almost exactly: 1-2% of invoices 0-30 days past due are ultimately written off, rising modestly to 3-5% at 31-60 days and 8-12% at 61-90 days.

The real break comes at the 90-day line: write-off rates jump to 25-40% once an invoice crosses into the 90-120 day bucket, then climb again to 40-60% for anything older than 120 days. That is the single steepest jump anywhere on the curve, roughly tripling in one aging step, which lines up with why 90 days is the threshold most collection guidance treats as the point of no return rather than just another milestone. Every week an overdue invoice sits without a reminder or escalation is a week spent sliding down this same curve.

Why does 90 days matter so much as a tipping point?

Because it is the point where a merely-late invoice starts turning into a genuinely at-risk one. At exactly 90 days past due, a commercial invoice is still 68.9% likely to be collected eventually, which means close to a third of the balance is already trending toward loss.

The same threshold shows up independently in the write-off data, where the jump from single-digit to 25-40% write-off risk happens in the exact same 90-day window. 5% of the total value of B2B invoices in North America was ultimately written off as bad debt in 2025, after collection efforts had run their course, per Atradius’s 2025 Payment Practices Barometer, and the majority of that written-off value almost certainly started as an invoice that crossed 90 days without resolution. Two independent datasets, tracking two different things (recovery probability and write-off rate), point to the same inflection point, which is a stronger signal than either number alone.

What should a business do before an invoice crosses 90 days?

Act inside the window, not after it closes. The data on follow-up discipline is unambiguous here: businesses that chase 100% of their overdue invoices get paid within a week 28% of the time, versus just 16% for businesses that leave some invoices completely uncontacted, a 76% relative improvement from consistency alone, according to Chaser’s 2026 Accounts Receivable Report. A reminder sequence that fires automatically the moment an invoice becomes overdue, rather than whenever someone remembers to check, is the highest-leverage move available while recovery odds are still strong.

If an invoice is still unpaid once it nears the 90-day mark despite reminders, that is the point to consider escalating to a commercial collection agency, where contingency fees typically run 20% to 50% of the amount recovered, according to Business News Daily’s 2026 buyer’s guide. Waiting past that window to make the call usually means paying the same fee against a much smaller chance of ever seeing the money, and an invoice that goes fully uncollected eventually joins the growing pool of bad-debt write-offs small businesses already report industry-wide.

Age of invoice	Recovery probability	What that means in practice
90 days past due	68.9%	Strong odds; the last reliable window for in-house follow-up
6 months past due	51.3%	Still better than a coin flip, but escalation should be underway
1 year past due	21.4%	Collection is now the exception, not the rule
2 years past due	8.9%	Recovery is rare; write-off is the realistic default

Age of invoice	Write-off rate	Trend
0-30 days	1-2%	Baseline risk
31-60 days	3-5%	Rising modestly
61-90 days	8-12%	Still contained
90-120 days	25-40%	Sharp jump
120+ days	40-60%	High risk

The Bottom Line

Every overdue invoice is running against a clock, and the data shows that clock is not linear. Recovery odds hold up reasonably well through the 90-day mark, at 68.9%, then fall off a cliff: 51.3% by six months, 21.4% by one year, and 8.9% by two years. Write-off risk mirrors that same shape from the other direction, staying in single digits through 90 days before tripling once an invoice crosses into the 90-120 day bucket. The practical implication is simple: the 90-day mark is not just one data point among many, it is the actual hinge the entire curve turns on. A business that runs a reminder sequence automatically from the day an invoice becomes overdue, rather than waiting for someone to notice it is late, is the single best way to keep an invoice on the strong side of that curve instead of the weak side of it.

Frequently Asked Questions

What is the recovery rate for an overdue invoice, by age? An unpaid commercial invoice is about 68.9% recoverable once it hits 90 days past due, according to benchmark data tracked by the Commercial Collection Agencies of America. That probability falls to 51.3% at six months, 21.4% at one year, and just 8.9% at two years past due.

How does write-off risk change as an invoice ages? Write-off risk stays low early and then climbs fast. Resolve’s original accounts-receivable aging analysis puts write-off rates at 1-2% for invoices 0-30 days past due, rising to 8-12% at 61-90 days, then jumping to 25-40% once an invoice crosses 90-120 days and 40-60% beyond 120 days.

Why does 90 days matter so much for invoice recovery? 90 days past due is the point where the aging curve bends hardest: a commercial invoice is still 68.9% collectible at that mark, but write-off rates jump from single digits to 25-40% in the same window, according to CCA of A and Resolve’s aging data. It is also the threshold most commercial collection agencies use to recommend placement.

Does following up on overdue invoices actually improve recovery odds? Yes. Businesses that follow up on 100% of their overdue invoices get paid within a week 28% of the time, versus 16% for businesses that leave some invoices completely uncontacted, a 76% relative improvement from consistent follow-up alone, according to Chaser’s 2026 Accounts Receivable Report.
