Debt Collection for Small Business 2026: 68.9% at 90 Days [Data]

Key Takeaways

68.9% of an unpaid commercial invoice is still collectible at 90 days past due, but that probability falls to 51.3% at six months, 21.4% at one year, and 8.9% at two years (Commercial Collection Agencies of America benchmark data).
Commercial collection agency contingency fees typically run 20% to 50% of the amount recovered, depending on the debt’s size and age (Business News Daily, 2026).
Collection agencies recover 20% to 25% of the dollar value placed with them industry-wide, versus 40% to 60% on accounts placed within 90 days of going overdue.
US debt collection agencies are projected to generate $16.1 billion in revenue in 2026 across 5,623 businesses (IBISWorld, November 2025).
US business bankruptcy filings climbed to 24,737 in 2025, up from 18,926 in 2023 and 23,107 in 2024 (The Kaplan Group’s analysis of federal court filing data).
5% of B2B invoice value in North America was ultimately written off as bad debt in 2025, after collection efforts had run their course (Atradius 2025 Payment Practices Barometer).

68.9% of an unpaid commercial invoice is still collectible at 90 days past due, according to benchmark data tracked by the Commercial Collection Agencies of America. That number is the entire argument for acting early: by six months, the odds fall to 51.3%, and by one year, they collapse to 21.4%. Every month an invoice sits untouched is a month of collectability draining away, and the data below shows exactly how fast.

How much of an unpaid invoice can you actually still collect?

It depends almost entirely on how long the account has been overdue, and the decline is steeper than most business owners assume. Benchmark data tracked by the Commercial Collection Agencies of America, cited widely across the commercial collections industry, puts the probability of successful collection at 68.9% for a debt that is 90 days past due. That falls to 51.3% at six months, then drops sharply to 21.4% at one year and just 8.9% at two years past due. The pattern holds because collectability is not really about the debtor’s ability to pay so much as their attention: a fresh invoice competes for a customer’s cash-flow priorities while the relationship and the paper trail are both intact, while a two-year-old invoice has usually been forgotten, written off internally by the debtor, or overtaken by their own business changes (a closed account, new ownership, or bankruptcy). This is also the core argument for not letting an invoice go unpaid without a reminder sequence doing the early follow-up automatically, since the same aging clock that erodes collectability starts the moment the invoice becomes overdue, not the moment someone finally notices.

What does a collection agency charge, and is it worth the fee?

Commercial collection agency fees are contingency-based in the vast majority of cases, and the range is wide. Business News Daily’s 2026 buyer’s guide puts typical contingency fees at 20% to 50% of the amount actually recovered, with the exact rate depending on the size of the debt and how long it has been outstanding; smaller, fresher balances sit at the low end, while older or harder-to-trace debtors push toward the high end. Whether that fee is worth paying comes down to a simple comparison: industry-wide, collection agencies recover roughly 20% to 25% of the dollar value placed with them across all account ages, but commercial recovery programs report 40% to 60% recovery on accounts placed within 90 days of going overdue. A 33% fee on a debt an agency has a 50% chance of recovering is a materially better trade than that same fee on a debt with a 21% chance, which is exactly why timing the handoff matters more than negotiating the percentage.

How big is the debt collection industry, and who is using it?

Large enough to be a real line item in the US economy. IBISWorld’s November 2025 industry report projects US debt collection agencies will generate $16.1 billion in revenue in 2026, spread across 5,623 businesses, with growth accelerating as delinquency-driven placements pick up. That demand is not abstract: 5% of B2B invoice value 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 for North America, and 43% of the total value of B2B credit sales was overdue at some point during the same period. Every one of those overdue balances is a candidate for either an in-house reminder sequence, a third-party agency, or eventually a write-off, and which path an invoice takes usually depends on how early the business acts, not on the debtor’s actual ability to pay.

Are more small businesses writing off unpaid invoices as bad debt?

The trend is moving in that direction. US business bankruptcy filings, a leading indicator of accounts that eventually become uncollectable no matter how aggressively they are pursued, climbed to 24,737 in 2025, up from 23,107 in 2024 and 18,926 in 2023, according to The Kaplan Group’s analysis of federal court filing data. That climb lines up with the broader rise in bad-debt write-offs small businesses are already reporting industry-wide. That is a rise of roughly 31% in just two years. For a small business, this trend matters less as a macro statistic and more as a planning signal: a customer that goes bankrupt while owing an invoice moves that balance from “slow to collect” to “essentially uncollectable” almost overnight, since unsecured trade creditors are typically paid last, if at all, in a bankruptcy proceeding. That is one more reason the 90-day collectability window matters so much: a debt collected or settled before a struggling customer files is money actually recovered, not a claim in a bankruptcy proceeding.

When should a small business escalate an unpaid invoice to a collection agency?

Before the 90-day mark, ideally, and definitely before it hits a year. The reminder-and-follow-up data is consistent on this point: businesses that follow up on every overdue invoice recover meaningfully more than those that let some invoices go uncontacted, and that gap only widens the longer an account sits untouched. A practical escalation path looks like this: automated reminders and a firm final notice email cover the first 60 to 90 days, and if the invoice is still unpaid once it crosses that 90-day threshold and the collectability curve above starts working against you, that is the point to hand it to a commercial collection agency or, for larger balances, small claims court. Waiting past a year to make that call, once collectability has already fallen to 21.4%, usually means paying the same contingency fee for a much smaller chance of ever seeing the money.

Age of the debt	Probability of collection	What that means in practice
90 days past due	68.9%	Strong odds; the best window for in-house follow-up or early agency placement
6 months past due	51.3%	Still better than a coin flip, but escalation should already 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

The Bottom Line

The data points in one direction: collectability is a clock, not a fixed property of the debt. At 90 days past due, 68.9% of a commercial invoice is still realistically recoverable; wait a year, and that number is 21.4%. The businesses that recover the most are not the ones with the toughest collection agency on retainer, they are the ones that act inside that first 90-day window, whether through consistent reminders, a firm final notice, or an early handoff to a professional agency when in-house follow-up stalls. With bankruptcy filings up 31% since 2023 and 5% of B2B invoice value already ending in write-offs, the cost of waiting is only getting steeper. Running a reminder sequence that fires automatically the moment an invoice goes overdue, rather than whenever someone remembers to check, is the single highest-leverage move available before an account ever needs to reach a collections desk.

Frequently Asked Questions

How much of an overdue invoice can still be collected after 90 days? About 68.9% of a commercial debt is still collectible at 90 days past due, according to benchmark data tracked by the Commercial Collection Agencies of America. That probability drops to 51.3% at six months, 21.4% at one year, and 8.9% at two years, which is why most commercial collection agencies recommend placing an account well before the one-year mark.

What percentage does a debt collection agency typically charge? Commercial collection agency contingency fees typically run 20% to 50% of the amount actually recovered, depending on the size and age of the debt, according to Business News Daily’s 2026 buyer’s guide. Fresh, smaller-balance accounts sit at the low end of that range; older or harder-to-locate debtors push fees toward the high end.

What is the average recovery rate for a debt collection agency? Collection agencies recover roughly 20% to 25% of the dollar value placed with them across all account ages, industry-wide. Accounts placed with an agency within 90 days of becoming overdue perform far better, with commercial recovery programs reporting 40% to 60% recovery rates on that early-placed group.

How big is the debt collection industry in 2026? US debt collection agencies are projected to generate $16.1 billion in revenue in 2026, spread across 5,623 businesses, according to IBISWorld’s November 2025 industry report.
