Comparison
Contingency vs. flat-fee collections
Updated 2026-10-24
Flat-fee collection programs charge a fixed amount per account, typically about $10–30, for a series of demand letters and sometimes calls, and the debtor usually pays you directly. Contingency collection charges nothing upfront and takes a percentage, commonly 15–50%, of what is recovered. Flat fee is usually cheaper for early, cooperative accounts and larger balances. Contingency is the better fit for older or unresponsive debtors, because you pay only when money comes in.
| Contingency | Flat fee | |
|---|---|---|
| How you pay | A percentage of the amount collected | A fixed fee per account placed |
| Typical price | Commonly 15–50% depending on age, size and volume | Typically about $10–30 per account |
| Cost if nothing is recovered | Usually nothing | The fee is still owed |
| What is included | Full collection effort: calls, letters, skip tracing, negotiation, legal referral | A set sequence of letters or emails, sometimes with limited calls |
| Where the money goes | Usually to the agency, which remits to you | Usually directly to you |
| Best account age | Roughly 90+ days or unresponsive debtors | Roughly 30–90 days with debtors still reachable |
| Best balance size | Any, but rate is lower on larger, newer balances | Larger balances where a percentage fee would be costly |
| Next step if it fails | Already included | Often converts to contingency at an added rate |
How flat-fee programs work
A flat-fee program is a structured letter campaign sent under the agency's name. You pay a fixed fee per account, and the debtor receives a series of notices over a few weeks saying the account has been placed with a third party. Payment usually goes straight to you, so you keep 100% of what comes in.
The tradeoff is scope. Most flat-fee programs are limited to written notices and a short timeline. They do not include extended phone work, skip tracing, or negotiation. If the debtor ignores the letters, many programs let you convert the account to contingency, with the new fee applied from that point.
How contingency works
On contingency, the agency takes on the full effort and the risk. We research the debtor, call decision-makers, negotiate, and refer to an attorney with your approval if needed. You pay a percentage of what is actually recovered. If we collect nothing, you usually owe nothing, though court costs for any approved lawsuit are a separate matter.
Rates depend on the work an account is likely to need. A recent, large balance from a business that is still operating costs less than an old, small balance from a debtor who has moved.
A simple cost comparison
Take a $3,000 invoice. A flat fee of $20 costs $20 whether the debtor pays or not. At a 25% contingency rate, a full recovery costs $750. If the debtor pays after the first letter, flat fee is far cheaper. If the debtor would have ignored letters and only paid after weeks of calls, the flat fee bought nothing, and you would then pay contingency on top.
For a large batch of accounts, the math depends on how many will respond to letters alone. Early, cooperative accounts favor flat fee. Older, silent accounts favor contingency.
Also count your own time. With flat fee, payments come to you, so your team records them and tells the agency when an account is paid. With contingency, the agency tracks payments and sends you remittance with a report.
When flat fee is the better choice
- Accounts are only 30–90 days past due and the customers are still in business
- You have many accounts and want a low, predictable cost per account
- Balances are large enough that a percentage fee would be expensive
- You want to keep the payment relationship directly with your customer
When contingency is the better choice
Many businesses use both: flat-fee letters for early accounts and contingency for anything that does not respond. We offer both and will recommend whichever fits the account.
Whichever model you choose, read the agreement for minimums, how long accounts stay placed, what happens if you recall an account, and whether fees apply to payments the debtor sends directly to you. Those terms often matter more than the headline rate.
- The account is 90+ days past due or the debtor has stopped responding
- You do not want to pay anything unless money is recovered
- The debtor may need to be located or researched first
- The account may need negotiation, a payment plan, or legal escalation
- You do not have staff to log direct payments and report them back to the agency
Frequently asked questions
Are flat-fee collection services worth it?
They often are for early-stage accounts where the debtor is reachable and just needs a firmer push. They are rarely worth it for old accounts or debtors who have already ignored several of your own notices.
Why does the contingency rate vary so much?
The rate reflects the expected effort. Older, smaller, or harder-to-locate accounts take more work per dollar recovered, so they carry a higher percentage. Larger volumes and newer accounts usually get lower rates.
Is a contingency fee charged on the full balance or only on what is collected?
Typically only on what is collected. If a debtor pays half the balance, the fee applies to that half. Confirm how the agreement treats direct payments the debtor sends to you after placement.
If a flat-fee account converts to contingency, do I pay twice?
You have already paid the flat fee, and contingency then applies to anything recovered after conversion. Ask how conversion is priced before placing accounts.
