A collection agency is a third-party firm that pursues overdue B2B receivables on behalf of a creditor, typically working on contingency and keeping 25 to 50 percent of whatever it recovers.
A collection agency is a specialist firm that pursues overdue debts on behalf of a creditor in exchange for a percentage of what it recovers or a flat fee per account. In B2B finance, agencies sit at the end of the receivables lifecycle. By the time an account is placed, internal collectors have usually exhausted email reminders, phone calls, and a formal demand letter. The agency exists because keeping a stale invoice on the books ties up capital, distorts DSO, and eventually forces a write-off if no further action is taken.
Understanding what agencies do, what they cost, and what they realistically recover is one of the most important commercial decisions an AR leader makes. Place too early and you pay a steep contingency on debts you could have collected yourself. Place too late and the recovery rate collapses. Treat agency placement as a routine policy step rather than a strategic choice and you risk burning customer relationships you could have preserved.
A B2B collection agency takes assignment of a debt and runs its own structured contact cadence against the debtor. That usually includes letters on agency letterhead, phone calls from professional collectors, skip tracing to locate the right contacts, credit bureau reporting on the commercial entity, and in some cases litigation support through partner law firms. Agencies often have leverage that internal teams lack, including the implicit threat of legal action, the ability to report to commercial credit bureaus, and a relationship with the debtor that is purely transactional rather than ongoing.
Most agencies will not begin work until the debt is properly documented. Expect to provide signed contracts or purchase orders, invoices, proof of delivery, the full payment history, and a record of every internal collection attempt. Weak documentation is the single biggest reason placements fail.
The right timing depends on the customer, the balance, and the dispute history, but a common pattern is to place B2B accounts somewhere between 90 and 180 days past due once internal escalation has run its course. Earlier placement makes sense when the customer has gone silent, refuses to engage, or has clearly entered financial distress. Later placement is appropriate when there is an active dispute being worked or a credible promise to pay in motion.
Three signals usually push an account to placement: the debtor stops responding entirely, the internal cost of one more contact attempt exceeds the marginal probability of payment, or the account is approaching a statutory limitations window beyond which it becomes harder to enforce.
There are two main commercial models. Contingency is the dominant approach in B2B, where the agency takes a percentage of what it collects and charges nothing on unrecovered balances. Typical contingency rates run from roughly 15 percent on large, fresh, well-documented commercial debts up to 40 or even 50 percent on small, aged, or complex accounts. Litigation work usually carries its own higher rate or hourly attorney fees on top.
Flat-fee or fixed-cost programs charge a set amount per account, often for first-effort or pre-collection work where the agency sends letters and makes a defined number of calls before any contingency clock starts. This can be economical for high volumes of relatively small balances.
Recovery rates matter as much as fee rates. On B2B placements, agencies typically recover 10 to 20 percent of the placed dollars across a mixed portfolio. Fresh accounts under 90 days past due can recover at 30 percent or more. Accounts older than 12 months often recover in the single digits. The blended net to the creditor, after the agency's cut, is what should drive the decision, not the headline contingency rate.
Agency placement is one of three real options for a seriously delinquent account. The second is continuing to work the account internally, which preserves the full recovered amount but consumes collector time that could be aimed at fresher, higher-probability balances. The third is litigation, which has the highest potential recovery on large balances but also the highest cost, longest cycle, and most severe relationship damage.
A simple framework: keep working internally while the marginal cost of one more touch is less than the expected value of payment. Place with an agency when that crossover happens and the balance is too small to justify litigation. Litigate only when the balance is large enough to absorb legal cost and the debtor has assets worth pursuing. Anything below the litigation threshold and beyond agency reach should move to write-off rather than sit on the books distorting metrics.
Placing too late is the most expensive error, because recovery rates fall faster than fee rates climb. Placing without documentation comes second; agencies cannot collect on debts they cannot prove. A third frequent mistake is double-working accounts, where internal collectors keep calling after placement and undermine the agency's leverage. A fourth is choosing on contingency rate alone rather than net recovery, ignoring an agency's actual track record on similar account profiles.
The traditional case for agency placement assumes that internal teams cannot scale the contact cadence, the skip tracing, and the personalised follow-up needed to recover late accounts. Agentic, AI-native collections platforms now close most of that gap. They can run a persistent multi-channel cadence on every overdue account, prioritise outreach by probability of payment, surface disputes early, and capture promises to pay without burning collector time. Recovery improves, the placement queue shrinks, and the accounts that do reach an agency are better documented and fresher. For many AR teams the result is a smaller agency spend, a higher net recovery, and far less collateral damage to active customer relationships.
A collection agency is a third-party firm that pursues overdue commercial invoices on behalf of a creditor. It takes assignment of the debt, runs its own contact cadence against the debtor, and keeps a percentage of whatever it recovers under a contingency agreement or charges a flat fee per account.
Most B2B creditors place accounts between 90 and 180 days past due, after internal collectors have sent reminders, made calls, and issued a formal demand letter without result. The right timing depends on the customer, the balance, and whether there is an active dispute or credible promise to pay that justifies waiting longer.
Contingency rates on commercial accounts usually run from about 15 percent on large, fresh, well-documented debts up to 40 or 50 percent on small, aged, or complex accounts. Litigation work generally carries a higher rate or separate attorney fees, and many agencies also offer flat-fee programs for first-effort or pre-collection outreach.
Across a mixed portfolio of B2B placements, agencies typically recover 10 to 20 percent of the placed dollars. Fresh accounts under 90 days past due can recover at 30 percent or more, while accounts older than a year often recover in the single digits. The right benchmark for any creditor is net recovery after fees on accounts that match their own customer profile.
It is worth it when the expected net recovery, after the contingency fee, exceeds what an internal collector could realistically achieve with the same effort. For aged accounts that have stopped responding, an agency almost always beats further internal work. For fresher balances or customers you want to keep, an agentic collections platform usually delivers more recovery with less relationship damage.
Yes. Agency placement is an adversarial step and most customers understand it that way. The relationship damage is often acceptable when the account is genuinely uncollectible internally, but it is the wrong move for customers you expect to sell to again. Earlier, AI-native collections that resolve the balance inside your own brand voice protect the relationship in a way third-party placement cannot.
