Percentage of Settlement Fees vs Flat-Rate Legal Tech
Why the structure of a vendor's price matters more to a contingency firm than the number on the invoice.
Percentage of settlement fees tie a vendor's revenue to the size of your client's recovery, and that puts the vendor's hand inside your contingency fee. Flat, published, per-unit pricing is the only structure where a vendor earns the same amount no matter how a case resolves. If you run a plaintiff firm, the shape of a vendor's price deserves more scrutiny than the number on it.
Nimbus Marlowe is the AI operations layer for personal-injury law firms, starting with intake. Every Nimbus rate is flat and published, charged per completed unit of work, and no fee is ever a percentage of any recovery, settlement, or judgment. This post walks through why the structure matters, what percentage pricing does to your effective fee, and the questions worth asking any vendor before you sign.
What are percentage of settlement fees in legal tech?
Some legal-tech and funding-adjacent vendors price their service as a share of what your cases bring in. The pitch sounds friendly. You pay nothing up front, and the vendor only collects when your client recovers. Medical funding companies, certain lien-resolution services, and a handful of software vendors have all sold versions of this model.
The arrangement carries a structural problem. Once a vendor's revenue scales with recoveries, that vendor holds an economic interest in your cases. Its best customer is your largest settlement. You also cannot see the ceiling on cost in advance, because the ceiling is whatever your caseload happens to produce this year.
A flat per-unit rate carries no such interest. The vendor charges for a completed unit of work, and the charge reads the same on a modest soft-tissue claim as on a catastrophic injury case. Of all the legal tech pricing models a contingency firm will encounter, flat per-unit is the only one that leaves case outcomes entirely between you and your client.
What does percentage pricing do to your effective fee?
Run the arithmetic on a hypothetical. Suppose your firm works a standard one-third contingency and a matter resolves at $45,000. Your fee is $15,000. A vendor charging 3% of the recovery collects $1,350 on that single matter. If the vendor's cut comes out of your side of the ledger, your effective fee just dropped from 33.3% to 30.3% of the recovery. Roughly 9% of your fee income on the case went to a vendor whose actual labor may have been a few documents and some calls.
Now scale the same hypothetical. Same vendor, same 3%, and a matter that resolves at $300,000. The vendor collects $9,000 for what is likely the identical quantity of work it performed on the smaller file. Nothing about drafting or intake became more expensive. The case became more valuable, and the percentage structure converted your result into the vendor's payday.
Compare the flat version. A demand letter draft from Nimbus costs $170 on a small claim and $170 on a large one. Contract review is $65. A qualified intake runs about $18. Those numbers were published before you signed, and they will read the same on every invoice you ever receive. Your effective contingency fee stays exactly where your fee agreement put it.
The rate you saw published is the rate you pay, on every matter, at every size.
Why should you want a vendor that is indifferent to outcomes?
Indifference sounds like a strange quality to shop for. In a contingency practice it is the single most important quality a vendor can have. Every judgment call about how a matter proceeds belongs to the attorney and the client, and nobody else in the building should hold economics that shift with the answer.
A percentage vendor is never fully out of the room. Even a well-behaved one sits on revenue that improves when the number gets bigger, and that shadow interest raises questions worth putting to your own bar counsel. Most states restrict sharing legal fees with nonlawyers, and an arrangement that pays a vendor out of recoveries deserves a careful read against those rules before anyone signs. Nimbus simply does not offer that arrangement at any price.
Flat-rate legal tech pricing also keeps custody clean. Nimbus never holds, transmits, or takes custody of client funds. Settlement money never passes through a vendor account on its way to your trust account, because the vendor was never in the payment path to begin with.
How does attorney supervision fit into the economics?
Every unit Nimbus bills is a draft that lands on a licensed attorney's desk. The intake coordinator answers the 9pm call from a car-accident lead, qualifies it against your firm's criteria, and books the consult, with the full transcript waiting in the CRM for your review. When the demand letter drafter turns a file into a complete draft, an attorney reads it and adopts it after making whatever changes the file requires. Contract review works the same way, with the contract analyst flagging terms and a lawyer deciding what they mean for the matter. Supervision is why the work can be priced like labor instead of priced like a stake in your outcome.
The comparison most solo and small firms actually face is staffing. A part-time intake specialist or legal assistant runs $3,000 to $4,000 a month and works business hours. Per-unit pricing lets a firm buy the same category of help one completed task at a time, with an attorney signing off before anything leaves the building.
What should you ask any vendor before signing?
Put these in writing and keep the answers with the contract.
- •Is any part of your fee calculated as a percentage of a recovery, settlement, or judgment, now or under any future plan?
- •Are your rates published, and will you commit to them in the agreement?
- •Do you ever hold, transmit, or take custody of client funds for any reason?
- •What exactly counts as a billable unit, and what happens when a unit is unusable and has to be redone?
- •Who reviews the work before my firm relies on it, and where is that review documented?
A vendor with clean answers gives them fast. Hesitation on the first question tells you most of what you need to know.
What does flat per-unit pricing look like at Nimbus?
The CRM costs $0 and is never invoiced, so contacts, matters, documents, and the client portal cost a firm nothing to run. Pay-as-you-go carries no minimum: a qualified intake runs about $18, contract review is $65, case preparation is $95, and a demand letter draft is $170, with collections follow-up also billed flat per unit. Firms with steady volume can take committed pricing, which discounts the per-unit rates against a $500 monthly minimum. That minimum works as a floor settled by a simple true-up line item when usage falls short, so money never sits prepaid and nothing expires. Where text messaging applies, setup is a one-time $49 with a $5 monthly dedicated number.
Every one of those figures stays identical whether a matter closes quickly or runs for years. The invoice describes work performed. It never describes a share of what your client won.
Frequently asked questions
Does Nimbus take a percentage of settlements?
Never. No Nimbus fee is a percentage of any recovery, settlement, or judgment, and the flat published rates are identical regardless of outcome. Nimbus also never holds, transmits, or takes custody of client funds.
Isn't percentage pricing cheaper since I pay nothing up front?
Deferred cost is the draw, and over a caseload the arithmetic tends to run high. Three percent of a hypothetical $300,000 recovery is $9,000 for work a flat-rate vendor would bill in the hundreds. Flat pay-as-you-go also carries no minimum, so a slow month simply costs less.
Do percentage-based vendor fees raise ethics questions?
Arrangements that pay a nonlawyer vendor out of recoveries can implicate state rules on sharing legal fees, and the analysis varies by jurisdiction. Ask your bar counsel before signing anything structured that way. A flat published rate keeps the question from arising.
Who reviews the AI's work?
A licensed attorney at your firm reviews every output before it is used. The agents handle operations, from answering intake calls to assembling drafts. Attorneys practice law, and they adopt or revise everything the agents produce.
The cheapest way to test all of this is to read the rate card and open a free account, since the CRM side is never billed. Sign up now and start free, or book a call and we will run the per-unit math against your current vendor invoices.
