Every contingency-fee PI firm advances costs on behalf of clients: filing fees, medical record requests, expert witness deposits, deposition transcripts, process server fees, and in major litigation, seven-figure expert and trial preparation budgets. Those advances are not fees. They are client obligations that the retainer agreement entitles the firm to recover from the client's share of the recovery. When the tracking system for those advances is informal, which is most commonly a spreadsheet updated when someone remembers, the firm routinely settles cases without recovering costs it actually spent, carries liability to clients whose cost disbursements it cannot document, and has no data for evaluating whether its case mix generates positive returns after costs.
Costs Versus Fees: The Accounting Distinction That Matters
The State Bar's accounting rules treat client costs as client funds, not firm revenue. Under California Rule of Professional Conduct 1.15, costs advanced on behalf of a client are the client's obligation and must be accounted for separately from the firm's operating account. When a firm receives a settlement check and deducts its costs from gross proceeds before calculating the attorney fee, the math must be documented: the settlement disbursement sheet should show gross recovery, attorney fee as a percentage of gross or net (per retainer terms), cost reimbursement as a separate line, and client net proceeds. A disbursement sheet that cannot account for every cost deducted from the client's recovery, with supporting documentation for each line item, is a potential trust account violation regardless of whether the client was ultimately made whole.
The practical implication is that the cost ledger for each case is not just a billing convenience; it is a regulatory document. The firm must be able to produce an itemized cost statement for any case at any time, including cases resolved years ago, if a bar complaint or fee dispute arises.
Per-Case Cost Tracking Architecture
The most reliable per-case cost tracking systems share three features: costs are recorded at the time they are incurred, not when the bill is paid; every cost entry is tied to a vendor invoice or receipt; and costs are categorized by type so that the firm can report cost composition by case type at year-end. Case management software platforms used in PI practice, including Filevine, Litify, and CASEpeer, include cost tracking modules that support these features natively. A firm that is still tracking costs in spreadsheets should treat migration to a case management platform with a cost ledger as an immediate operational priority rather than a future enhancement.
Cost categories should be standardized across the firm's cases. A consistent taxonomy, such as medical records, expert fees, deposition costs, filing fees, investigation, and trial expenses, allows the firm to analyze cost patterns across cases and to catch anomalies quickly. A personal injury case with fifty thousand dollars in costs before a demand letter is sent is a data point that should trigger management review, not something that surfaces only when the file closes.
Managing High-Cost Cases and Expert Budgets
In cases with significant expert exposure, expert fees deserve a separate budget review at case initiation and checkpoint reviews at 60, 90, and 120 days after retention. An expert retained without a defined scope and budget is an unlimited commitment. The retention agreement with every expert should include a scope of work, an estimated fee range, and an approval requirement for work outside that scope. Without that structure, expert costs in complex cases can accumulate beyond the range where the firm can recover them from any realistic settlement.
Cost advance policies should also address which costs require managing attorney approval before incurrence. Routine costs like medical record fees and process server fees can be delegated to paralegals. Expert retention, deposition scheduling, and any cost item exceeding a firm-set threshold should require explicit attorney sign-off. This is not about administrative friction; it is about ensuring that the attorney responsible for the case's outcome has made a deliberate decision about its cost trajectory.
Cost Recovery at Settlement and Profitability Analysis
At settlement, the cost recovery step is where the tracking system either pays off or fails. A well-maintained cost ledger produces an itemized cost statement that can be reviewed with the client and attached to the settlement distribution sheet. In California, the client is entitled to an accounting of all costs deducted from the recovery, and providing a clear, documented accounting minimizes post-settlement disputes about whether costs were accurately charged.
At the firm level, case-close data should feed into a profitability report that tracks fee recovered, costs recovered, and net margin by case type, originating attorney, and referral source. A personal injury practice that has never analyzed its economics by case type is operating without the information it needs to decide where to invest its time and capital. Cases that consistently generate high costs relative to recovery are cases the firm should either improve its screening on or decline. Cases that generate positive margins efficiently are the cases the firm should build its referral pipeline around.
For the related topic of cost recovery at settlement and how costs interact with lien disbursements in the distribution waterfall, the liens-and-settlement category covers settlement accounting in detail. The practice systems and intake workflow frameworks that determine which cases enter the cost pipeline in the first place are covered more broadly in the practice-operations category.
