Every legitimate investigative firm has to answer the same practical question a client will eventually ask: how does the billing actually work. The answer matters more than it might seem, because the fee structure a firm proposes is often the fastest available signal of whether the engagement is genuine analytical work or a promise built to extract money from someone who is already anxious to get funds back.
The three billing models that hold up
A retainer arrangement asks for an upfront deposit that is drawn down against actual hours worked, with itemized time recorded against it and any unused balance returned at the end of the engagement or when the case concludes. Hourly billing charges a stated rate for time actually spent, with regular, itemized statements showing what was done during the billed hours, comparable to how a law firm or forensic accountant typically bills. A flat fee covers a clearly defined, bounded piece of work, most often a specific trace and report deliverable, agreed before work begins and not tied to whether the trace ultimately leads anywhere useful. All three share a common feature: the client is paying for labor that has demonstrably occurred, documented in enough detail to be checked.
Why a pure contingency fee is a red flag
A model that charges nothing upfront and instead takes a percentage of whatever is recovered sounds appealing precisely because it seems to align the investigator’s incentive with the client’s outcome. In practice, it runs into a structural problem: blockchain tracing, report writing, and legal coordination take real hours regardless of whether the case ultimately produces a recovery, and a firm cannot indefinitely absorb that cost across every case that goes nowhere while only getting paid on the ones that succeed. A firm advertising this model is usually doing one of two things, quietly building the eventual fee high enough to cover its losses on every case that fails, often disclosed only once a recovery is imminent, or not actually performing the underlying work at all and instead using the promise of a contingency arrangement to justify a smaller "administrative" or "processing" fee requested upfront. That second version is functionally identical to the upfront-fee recovery scam this industry is most associated with, dressed in more professional-sounding language.
The phrase "no recovery, no fee" is closely associated with upfront-fee scams precisely because it exploits the same hope a genuine victim already feels. A legitimate firm can be transparent about the low probability of full recovery in many cases specifically because it is not depending on a recovery to get paid for the work already done.
Questions worth asking before engaging any firm
- What exactly is the billing model, and can it be put in writing in an engagement letter before any payment is made.
- What specific deliverable does the engagement produce, a documented trace report, direct contact with an exchange’s compliance or legal team, a filing with law enforcement, and is that scope defined up front.
- What are the analyst’s relevant qualifications, and has the firm handled a case of comparable size or complexity before.
- What happens if the trail goes cold partway through, does billing stop, and is a partial report still provided documenting what was found.
- Is the firm willing to have its identity, registration, and past client references independently verified before any funds are sent.
None of this guarantees a positive outcome, and no honest firm will claim otherwise. What it does is separate firms willing to be paid for documented work from arrangements built around a promise that only makes sense if the person offering it never intended to be held to it.
