What would happen to a $5,000 unpaid business invoice if a collection agency recovered it tomorrow—and how much of that money would your company actually keep?
In a common commercial collection arrangement, the answer is $3,250. At a 35% contingency fee, the agency takes $1,750 after recovering the full invoice, leaving the creditor with the balance. That simple calculation captures the central trade-off: you may avoid paying an upfront fee, but successful recovery is shared with the company doing the work.
For commercial debt collection in the United States, agencies commonly charge between 10% and 35% of the amount recovered. The rate is not pulled from a fixed menu. It reflects the size of the account, how old the debt is, whether the debtor is easy to locate, the quality of the documentation, and the amount of pressure or negotiation required.
A large, recent invoice from a clearly identified business may attract a lower percentage because it presents a relatively clean recovery opportunity. A small, disputed account that has been ignored for months is a different animal. The agency may need to investigate the debtor, review contracts and invoices, make repeated contact attempts, and decide whether escalation makes financial sense. The percentage rises as the expected effort and risk rise.
The broad market range can stretch further. For 2026, commercial collection quotes may land anywhere from roughly 20% to 50% of the recovered amount, particularly for difficult or aged accounts. That does not mean every creditor will be charged 50%. It means the age and condition of the receivable can move the fee well beyond the rates associated with straightforward, recent debt.
Age is one of the clearest pricing signals. B2B debts less than 90 days old are often quoted at about 25% to 35%. Once an account passes the 90-day mark, rates commonly move to approximately 35% to 50%. A late invoice is not automatically a bad debt, but time changes the collector’s leverage. The debtor may have stopped responding, disputed the work, changed offices, shut down operations, or simply moved the account far down its payment list.
That is why sending an account to collections early can matter financially even if the business relationship is already strained. A fresh receivable usually gives the collector better records, clearer contacts, and a more credible payment demand. Waiting can turn a commercial invoice into a small investigation.
Some businesses do not need full contingency collection at the start. They may want a firm payment demand, a few carefully managed calls, or a review of the account before deciding whether litigation is justified. This is often called soft collection, and it may be priced at a flat fee of about $15 to $35 per account.
That model can make sense for a company with many overdue invoices and a consistent process. A modest fixed charge lets the creditor test whether a professional intervention will prompt payment without immediately giving up a large share of the receivable. It also suits accounts where the debtor is likely to pay after receiving a formal demand but does not respond to ordinary reminders.
The economics change if the account needs legal attention. Specialized legal collection work may cost approximately $50 to $100 per hour. An attorney might review the agreement, assess a defense raised by the debtor, prepare a demand letter, negotiate a settlement, or advise the creditor on whether filing suit is sensible. Hourly billing gives the creditor a clearer connection between time spent and cost, but it also introduces the possibility of paying for work without recovering the debt.
A separate contingency arrangement may be available for legal work. Lawyers often charge around 20% to 30% of the amount recovered, depending on the agreement and the complexity of the case. That fee may be added to an agency’s collection commission rather than replacing it. If the contract allows both charges, the total cost can become much higher than the headline percentage shown in an agency’s first proposal.
This is the part that deserves close attention. A quote saying “35% contingency” may sound straightforward, but the contract should answer several practical questions. Does the percentage apply to principal only, or also to interest and late fees? Is the fee calculated on money received in installments? What happens if the debtor pays the creditor directly after the account is assigned? Are court filing fees, process-server charges, skip tracing, travel, or attorney fees billed separately?
Those details can change the result more than a few percentage points. Suppose a $20,000 invoice is recovered at a 25% fee. The agency earns $5,000 and the creditor receives $15,000 before any separate expenses. At 45%, the agency’s share becomes $9,000, leaving $11,000. The dollar difference is $4,000, which is not a minor adjustment for a small business.
The apparent bargain of “no collection, no fee” also needs to be understood accurately. In a pure contingency arrangement, an unsuccessful recovery commonly produces a $0 collection fee. That does not necessarily mean the entire process is free. A contract may still allow expenses, legal charges, or administrative costs, so the creditor should distinguish the contingency fee from every other possible charge.
The value of a collection agency is not measured only by the percentage it retains. Internal collection work takes time, and employees may spend hours chasing invoices instead of serving customers, managing cash flow, or handling new business. An agency can also create distance between the creditor and a difficult debtor. That distance is useful when a company wants payment but does not want its sales team arguing with a customer over a disputed balance.
Still, the numbers should be tested against the likely recovery. Paying 35% to recover a debt that would otherwise remain unpaid can be a strong result. Paying 50% on a very old account may also be rational if the alternative is receiving nothing. But hiring a collector for an account with weak documentation, a serious contractual dispute, or a debtor with no apparent assets may produce activity without producing money.
A useful decision starts with the net amount, not the advertised rate. Estimate what is realistically collectible, subtract the agency’s fee, then account for legal or administrative expenses. A $10,000 invoice with a 30% contingency fee yields $7,000 before additional costs if fully recovered. If the collector believes only $4,000 is likely to come in, the expected net is closer to $2,800. That calculation may feel a little cold, but it is more useful than staring at the original invoice total.
The agreement’s definition of “recovered” matters too. Some contracts charge when the debtor makes a payment, while others address settlements, payment plans, returned checks, or accounts paid after the collection period ends. A creditor should know whether accepting a reduced settlement changes the fee and whether the agency must obtain permission before agreeing to one.
Commercial debt collection is therefore less like buying a standard service and more like pricing a risky financial transaction. Recent, well-documented debts tend to command lower rates. Older accounts, disputed invoices, and cases requiring attorneys can reach 35% to 50% or more once all layers of cost are considered. On a $5,000 recovery, that difference is the gap between keeping $3,250 and keeping only $2,500.
The best contract is not necessarily the one with the lowest percentage. It is the one that makes the total cost visible before the first demand goes out, especially once legal work enters the picture.
