The case against the billable hour

Kill the billable hour. Keep the margin.

The billable hour rewards slow lawyers and punishes efficient ones. It teaches clients to dread every email, every call, every minute on the clock. It hides cost overruns until the invoice lands. There is a better way to run a modern practice.

It punishes the client for your speed

The faster and more experienced you get, the less you earn per matter. Clients pay more for juniors learning on their case than for the partner who could have closed it in an afternoon. That is a broken incentive, not a pricing model.

It hides cost overruns until it's too late

Internal effort piles up quietly until billing day. By then the matter is unprofitable and the write-off conversation has already started. Fixed fees with live telemetry surface the erosion on day three, not day ninety.

Clients want predictability, not surprise

In-house counsel and individual clients budget in fixed numbers. A quoted fee with clear inclusions, exclusions, and a deterministic amendment process is the difference between a referral and a complaint.

Fixed fees only work with real cost data

Moving away from hourly billing fails when firms guess the price. Teryn AI builds the fee from your internal cost per role and your Target Margin, then tracks actual internal effort against that plan in real time.

    Real quotes from the lawyers, authors and firm leaders who've spent decades arguing that fixed-fee pricing is the future. Scroll →

    The legal industry is being reshaped by clients who buy legal services the same way they buy every other business input — on scope, price and outcome. Firms still selling time are competing on the axis buyers value least.

    Cost Engine

    Price by outcome, not by hour.

    Model every fixed fee against your firm's true cost-to-deliver across salary, on-cost, utilisation and target margin, so you win the work that is profitable, not just the work that fills the diary.

    Kill the billable hour. I'm a trial lawyer. I bill by the hour. So do the associates who work for me. It is frankly nuts. The billable hour rewards slow lawyers and punishes efficient ones.

    Margin at Risk

    Cost overruns never wait for the invoice.

    Margin at Risk tracks the agreed fee, live cost-to-deliver and milestone progress in real time, so overruns surface on day three, not in a write-off conversation at month-end.

    Tomorrow's lawyers will need to be very different from most of today's lawyers. Clients will no longer tolerate being charged for effort rather than value delivered.

    Milestones

    Priced by outcome, tracked by deliverable.

    Break each matter into milestones with owners, effort and cost. Clients see progress against outcomes; you see the true cost-to-deliver as each stage completes.

    Corporate legal departments are under sustained pressure to control outside-counsel spend, and alternative fee arrangements have moved from experiment to expectation on a growing share of matters.

    Fee Amendments

    Change the price the professional way.

    When scope shifts, issue a formal Fee Amendment with a calculated uplift backed by milestone data and cost telemetry, so there is no awkward invoice-day surprise and no write-off.

    Clients continue to expect greater price transparency and predictability from their law firms, and firms that cannot deliver both are steadily losing share of wallet.
