B2B claims Flat fee You stay the creditor

Commercial collections attorney alternative and what a commercial collection lawyer costs

Most commercial collection law firms quietly decline claims under $5,000 to $10,000, because the retainer and court costs eat the recovery. This page shows the real arithmetic at each claim size, and what to run below the threshold.

Fee figures on this page were read off collection firms' own published pages in September 2026. Where a firm publishes no number, we say so rather than estimate.

The short answer

A commercial collections attorney is a lawyer who recovers unpaid business to business debts through demand, suit and judgment enforcement. Expect roughly 10% to 30% contingency for pre-suit work and 30% to 35% once a lawsuit is filed, plus cost advances from $1,300 and a non-contingent fee of $1,000 to $2,500 that you pay up front. Most commercial collection law firms will not take a claim below $5,000 to $10,000, because those numbers cannot be justified on a small balance.

That threshold is the whole decision. Above it, an attorney buys you something no software can: the ability to force the issue in court and, where your contract or state law allows it, shift your legal fees onto the debtor. Below it, you are paying fixed costs that do not shrink with the invoice, and the arithmetic stops working. DebtAgent is built for what sits below the line: a flat monthly fee that runs a structured email, SMS and voice escalation on every open invoice in your aging report, with you as the creditor of record. We are not a law firm and we do not file suit. If your debtor has assets and simply refuses to pay, hire the attorney.

01 The economics nobody puts on a practice page

Why claim size decides whether a commercial collection lawyer is worth hiring

An attorney's costs are mostly fixed. Your invoice is not. That single mismatch explains every quote you will get.

01

The fixed costs do not scale down

A retainer starting around $250, filing fees, and service of process cost roughly the same whether the claim is $3,000 or $300,000. The Kaplan Group's litigation cost page puts initial cost advances at $1,300 and up, plus a non-contingent fee of $1,000 in about two thirds of suits and up to $2,500 in the rest. On a $3,000 invoice that is up to a third of the balance before anyone argues the merits.

02

Contingency rises as the balance falls

Commercial rates move inversely to claim size. The Kaplan Group's published 2026 scale runs 25% on claims of $3,000 to $9,999, 20% from $10,000 to $49,999, 15% from $50,000 to $499,999 and 10% above $500,000. The smaller your problem, the larger the share you surrender, and that is true at every commercial provider, not just this one.

03

Most firms have a minimum you will not see advertised

Commercial collection law firms and agencies commonly work to an informal floor of $5,000 to $10,000. The Kaplan Group states it plainly in its FAQ: for new clients, the average claim size needs to exceed $5,000. Firms that do take smaller matters generally handle them as demand letter work rather than litigation, because as one commercial firm puts it, on claims of that size the costs of suit cannot be justified.

04

A judgment is not the money

Winning ends the argument and starts the collection. Enforcement means locating assets, garnishment, liens and levies, each with its own cost. A widely cited estimate from attorney Joe Dickerson, published in the ABA Journal on 2 April 2020, puts unenforced US civil money judgments at around 80%. It is an experienced practitioner's estimate rather than a study, and it is the right thing to plan around.

05

Fee shifting is real but conditional

A court can pass your attorney's fees to the debtor, which is the strongest argument for hiring one. It requires a fee clause in your contract or a statute that allows it, a judgment in your favor, and a debtor with assets to take it from. Three conditions, all of which have to hold.

06

Age destroys value faster than fees do

Accounts under 90 days past due commonly recover above 70%. Past 180 days the rate often falls below 15%. The months spent choosing a firm and negotiating an engagement are themselves a cost, and they are usually larger than the difference between a 20% and a 25% contingency.

02 How it works

How to decide between an attorney, an agency and a sequence

Four checks, in the order that costs you the least to run.

  1. Step 1

    Sort the ledger by balance, not by age

    Split your open invoices at roughly $10,000. Everything above the line is worth an attorney conversation. Everything below it is where fixed legal costs stop making sense, and it is usually the larger half of the list by count and the smaller half by value.

  2. Step 2

    Read your own contract before you call anyone

    Look for a prevailing party attorney fee clause and an interest or late fee provision. If the fee clause exists, litigation on a mid sized claim is materially more attractive, because a win can move your legal cost onto the debtor. If it does not, you are paying every dollar of it yourself.

  3. Step 3

    Run a structured escalation on everything below the line first

    Most unpaid B2B invoices are not disputes. They are an invoice that reached the wrong inbox, an approver who left, or a payables queue that only responds to a schedule. A sequenced series of emails, texts and calls resolves a large share of those without a percentage or a filing fee, and it costs the same whether you run it on 5 invoices or 500.

  4. Step 4

    Escalate the survivors, with a documented trail

    What is left after a disciplined sequence is the genuine refusal: the debtor who has been reached, has acknowledged the invoice, and still will not pay. That is exactly the file an attorney wants, and the contact history makes the engagement cheaper. Escalate those, and only those.

03 Priced side by side

What each route costs on the same $25,000 unpaid invoice

Figures are from each provider's own published pages, read September 2026. Where a provider publishes no number we say so rather than guess. Recovery is never guaranteed by any of these routes.

Route What you pay Cost on $25,000 recovered Can it force payment?
Commercial collections attorney, suit filed 30% to 35% contingency, plus cost advances from $1,300 and a $1,000 to $2,500 non-contingent fee. Kaplan Group quotes cost advances from $1,300 plus a $1,000 to $2,500 non-contingent fee Roughly $8,700 to $9,600 Yes. Judgment, then enforcement
Commercial collections attorney, pre-suit demand Commonly 10% to 30% of what the demand recovers $2,500 to $7,500 No, but the letterhead carries weight
Commercial collection agency Contingency by band. Kaplan Group publishes 20% for claims of $10,000 to $49,999 and 25% on claims of $3,000 to $9,999; the wider market runs 15% to 50% $5,000 at 20% No. Can refer to an attorney
Flat fee agency placement Rocket Receivables publishes $21.95 per account at 10, $17.95 at 25, $14.95 at 50+, Stage One recoveries returned in full Under $25 for the account No. Stage Two past 120 days is a 50/50 split
DebtAgent $49, $149 or $499 a month flat, per organization, any number of invoices $149 for the month, whatever you recover No. You stay the creditor of record

DebtAgent is not a law firm and not a collection agency. We do not file suit, record liens, garnish wages, levy accounts or report to credit bureaus. On a claim where the debtor has assets and has refused in writing, an attorney is the correct tool and we will say so.

How much does a commercial collections attorney cost?

Expect three separate charges. Pre-suit demand work is commonly quoted at 10% to 30% of whatever the demand recovers. Once a lawsuit is filed, contingency typically rises to 30% to 35%. On top of that sits a non-refundable, non-contingent fee, which the Kaplan Group publishes as $1,000 in about two thirds of suits and up to $2,500 (or 5% of the claim) in the rest, and cost advances starting at $1,300 that you pay up front and do not get back if the debtor turns out to be judgment proof. The same firm says a further $250 to $500 is usually needed for judgment collection, and $2,000 or more against an obstinate debtor.

Add those together on a $25,000 invoice and full recovery through litigation leaves you with roughly $13,700 to $16,500. That is before enforcement, which is a separate exercise with its own bill. Hourly work exists too, generally $200 to $450 an hour, but on a collections matter it usually appears only when the debtor counterclaims and someone has to defend it.

The number that actually decides this is not the percentage. It is the fixed portion. A $450 to $1,350 floor of retainer plus court costs is a rounding error on a $250,000 claim and a serious loss on a $4,000 one.

What is the minimum amount a commercial collection attorney will take?

Commercial collection law firms commonly work to an informal minimum of $5,000 to $10,000 for anything they would litigate. The Kaplan Group is unusually direct about it, stating in its FAQ that for new clients the average claim size needs to exceed $5,000. Some will accept smaller matters as demand letter work at a flat fee or a higher contingency, but they are not filing suit on them. As one commercial collections firm puts it, a claim can be as small as $1,500, but unless the debtor cooperates there is no litigation option, because the costs of suit cannot be justified at that size.

You will rarely see this on a practice area page. It comes up on the intake call, after you have spent a week finding the firm. If most of your ledger sits under $10,000, plan for it now: that portion of your receivables is never going to court, and the question is only whether you chase it systematically or write it off.

Is it worth hiring a lawyer for an unpaid invoice?

It is worth it when three things are true at once. The balance is large enough that a percentage plus roughly $450 to $1,350 in fixed costs still leaves you materially better off. The debtor is solvent and locatable, so a judgment can actually be enforced. And the debtor has stopped responding or has refused, which means the problem is genuine unwillingness rather than a broken payables process.

It is not worth it when the invoice is under about $10,000, when the debtor is a dissolved entity or has no reachable assets, or when nobody has actually made contact yet. That last one is more common than finance teams expect. A large share of overdue B2B invoices are sitting in an approval queue that never got a follow up, and they clear the moment someone applies a schedule to them.

Should I use a collection agency or an attorney?

Use an agency when you want recovery attempted at scale without litigation, and you accept a percentage. Use an attorney when litigation is genuinely on the table, or when the debtor is sophisticated enough that only a filed complaint will move them. The practical difference is leverage: an agency can ask, an attorney can sue.

Two things worth checking on either. First, ask whether the firm is certified by the Commercial Law League of America, whose program has run since 1975 and requires an annual operational audit by independent CPAs, separately verified client trust accounts, surety bonding and enforced remittance standards. The CLLA publishes a public list of certified agencies, almost no roundup mentions it, and it is the single best screening question on the commercial side. Second, read the direct payment clause. Most placement agreements still earn the agency its percentage if your customer pays you directly after placement. It is standard, it surprises people, and it moves the effective rate more than the headline number does.

Also note that pure business to business debt sits outside the Fair Debt Collection Practices Act, which under 15 USC 1692a(5) covers debt incurred primarily for personal, family or household purposes. State licensing and bonding rules still aim at third party collectors, which is one reason staying the creditor of record on your own invoices is a simpler position.

Can you recover attorney fees in a debt collection lawsuit?

Sometimes, and it is the strongest reason to litigate a mid sized claim. American courts default to each side paying its own fees, so recovery depends on either a prevailing party attorney fee clause in the contract the debtor signed, or a statute in your state that shifts fees in this type of action. If you have one, a $25,000 claim looks very different, because the litigation contingency may end up on the debtor's side of the ledger.

Two cautions. A fee award is still only a number on a judgment, and it has to be enforced like any other. And the clause has to be in the agreement before the dispute, not added to an invoice afterward. If you are writing terms for next year, this is the clause to add. We cover the mechanics in more depth in our guide to prevailing party attorney fees on unpaid invoices.

How long does a commercial collection lawsuit take?

Plan on months, not weeks, and treat any firm that promises otherwise with suspicion. A demand letter cycle runs a few weeks. Filing, service and the debtor's response window add more, and a contested matter with discovery can run past a year depending on the court's calendar. If the debtor defaults, it is considerably faster, but you then move straight into enforcement, which is its own timeline.

This matters because of the recovery curve. Accounts under 90 days past due commonly recover above 70%, and past 180 days the rate often falls below 15%. Time spent selecting counsel is time the balance is aging. Running a structured escalation on the account while you evaluate firms costs you nothing in leverage and frequently resolves it before the engagement letter is signed.

What DebtAgent does, and what it deliberately does not

DebtAgent runs the escalation an attorney will not profitably run and an agency charges a percentage for. You connect your aging report, and it works every open invoice on a schedule: sequenced email, SMS and voice contact, with the tone stepping up as the account ages, and everything logged. You remain the creditor of record throughout, so the customer relationship stays yours and nothing is placed with a third party. Pricing is $49, $149 or $499 a month, flat, per organization, regardless of how many invoices you run or how much you recover.

What it does not do matters just as much. We do not file suit, obtain judgments, record liens, garnish wages, levy bank accounts, or report to credit bureaus. We are not a law firm and nothing here is legal advice. If your claim is above $10,000, the debtor is solvent, and they have refused in writing, an attorney is the right call and the contact trail DebtAgent produces makes that engagement cheaper to run. The two are sequential, not competing.

04 Questions people actually ask

Commercial collections attorney questions

How much does a commercial collections attorney charge?

Roughly 10% to 30% contingency for pre-suit demand work and 30% to 35% once suit is filed, plus a non-contingent fee the Kaplan Group publishes as $1,000 to $2,500, plus cost advances from $1,300 paid up front. Hourly work runs about $200 to $450 an hour and usually appears only if the debtor counterclaims.

What is the minimum claim a commercial collection lawyer will take?

Commonly $5,000 to $10,000 for anything a firm would litigate. The Kaplan Group publishes that a new client's average claim size needs to exceed $5,000. Smaller matters are sometimes taken as demand letter work but not for suit, because a $1,300 cost advance plus a $1,000 to $2,500 non-contingent fee cannot be justified on a small balance.

Is a commercial collections attorney better than a collection agency?

For leverage, yes: an attorney can file suit and an agency cannot. For cost on a mid sized claim, often no, since published agency contingency for claims of $10,000 to $49,999 runs around 20% against 30% to 35% plus fixed costs once litigation starts. Match the tool to whether litigation is genuinely on the table.

Can I recover my attorney fees from the debtor?

Only if your contract has a prevailing party attorney fee clause or a state statute shifts fees in that action, you win, and the debtor has assets. The clause must predate the dispute. Where all three hold, litigating a mid sized claim becomes materially more attractive.

Does DebtAgent file lawsuits or send attorney demand letters?

No. DebtAgent is not a law firm and not a collection agency. It runs sequenced email, SMS and voice contact on your open invoices while you stay the creditor of record. It does not file suit, record liens, garnish, levy or report to credit bureaus.

Is business to business debt covered by the FDCPA?

Generally no. Under 15 USC 1692a(5) the Fair Debt Collection Practices Act covers debt incurred primarily for personal, family or household purposes, so pure commercial debt sits outside it. State licensing and bonding rules still target third party collectors, which is a reason to keep collection in your own name.

How do I check that a commercial collection firm is legitimate?

Ask whether it is certified by the Commercial Law League of America, which publishes a public list of certified agencies. That program, running since 1975, requires an annual operational audit by independent CPAs, separately verified client trust accounts, mandatory surety bonding and enforced remittance standards. Then read the direct payment clause, which usually still earns the firm its percentage if your customer pays you directly after placement.

What should I do with invoices below the attorney threshold?

Work them systematically rather than sporadically. Most overdue B2B invoices are process failures, not refusals, and a scheduled escalation clears a large share of them. What survives a disciplined sequence is a documented refusal, which is the only kind of small claim worth escalating further.
