Fixed Fee in LeanLaw: Overview & How It Works

Whether you’re billing a single flat amount for a matter, charging fixed fees for specific tasks, or combining fixed and hourly work, LeanLaw lets you manage it all in one consistent workflow.

This article explains what Fixed Fee means in LeanLaw, common use cases, and the core building blocks that make fixed-fee billing work.

In LeanLaw, a Fixed Fee is a predefined amount you charge for work, regardless of how much time is ultimately spent.

Unlike hourly billing:

Time is still tracked—but for internal purposes only.

With Fixed Fee billing, you can still:

Key insight: Clients see clean, flat-fee invoices. Your firm still sees the time, cost, and profitability behind the work—without added billing complexity.

Fixed Fees live alongside your normal time and billing workflows, so you don’t have to choose between flat-fee simplicity and operational visibility.

Firms use Fixed Fees in LeanLaw in a variety of ways.

Charge a single flat amount for an entire matter, such as:

Apply fixed fees to specific tasks within a matter, like:

This allows you to mix fixed-fee and hourly billing in the same matter—for example, charging a fixed fee for drafting a complaint while billing discovery hourly.

Many firms combine:

LeanLaw fully supports this hybrid approach without requiring separate matters or special workarounds.

A Fixed Fee entry defines the flat amount you intend to bill. This is where you specify:

Fixed Fee entries control what ultimately appears on the invoice.

Even though clients aren’t billed by the hour, your team can still log time against fixed-fee work using Fixed Fee time entries.

These time entries:

Tracking fixed-fee time helps you understand how much work goes into each engagement and whether your pricing is sustainable.

For work that should only be billed once it’s finished, LeanLaw supports completion-based fixed fees.

With completion-based billing, the fixed fee is:

This is especially useful for milestone-based or outcome-driven work.

When you generate an invoice, LeanLaw includes Fixed Fee entries as single line items.

LeanLaw combines fixed fee amounts with tracked time and costs to give you insight into:

For example, if you charge $2,500 for a trademark filing and your team logs 15 hours at an average internal rate of $200/hour, you can see that the effective realization is 83% ($2,500 ÷ $3,000).

These insights help you:

Fixed Fee billing in LeanLaw lets you offer predictable pricing to clients without sacrificing insight into your firm’s performance.

By combining fixed fee entries, internal time tracking, completion-based billing, and clear invoicing, you get the best of both worlds: simple invoices for clients and actionable data for your firm.
