Billable vs Non Billable Hours
Billable hours are client work that can usually be charged. Non billable hours support the business but are not usually invoiced directly. This guide explains the difference, examples, and how to track both accurately.
Billable hours are hours spent on client work that can be charged to a client.
Non billable hours are work hours that cannot usually be charged directly to a client, even though they may still be important to the business.
The difference matters because professional services firms need to understand how time is spent, what work creates revenue, and where valuable work may be missed.
Simple example A lawyer reviewing a contract for a client is usually doing billable work.The same lawyer attending an internal firm training session is usually doing non billable work.Both may be necessary. Only one is usually charged to the client.
What Are Billable Hours?
Billable hours are hours spent on work that can be invoiced to a client. In a law firm, billable hours may include legal research, client calls, contract review, matter-related emails, drafting, court preparation, discovery review, or negotiation preparation.
In other professional services firms, billable hours may include consulting work, accounting work, audit support, client implementation work, technical services, or client project delivery.
👉 The key question is: did this work directly support a client matter, project, case, or engagement? If the answer is yes and the client agreement allows it, the time may be billable.
What Are Non Billable Hours?
Non billable hours are work hours that are not usually charged directly to a client.
Non billable work may still be valuable. It often supports the firm's operations, growth, people, systems, or long term quality.
Examples include internal meetings, training, marketing, business development, administration, recruiting, internal reporting, general research, and software setup.
Non billable does not mean useless. It means the time is not usually invoiced to a client.
Billable vs Non Billable Hours: Main Difference
The main difference is whether the work can be charged to a client. Billable hours are connected to client work and may become revenue. Non billable hours support the business but are not usually invoiced directly.
Billable
Reviewing a contract for a client
Preparing a client report
Attending a client strategy call
Non billable
Joining a general firmwide meeting
Updating an internal process document
Attending internal software training
The distinction depends on the client agreement, billing policy, matter type, and work performed.
Examples
Billable Hours Examples
Common billable work examples include:
Client meetings
Client calls
Matter related emails
Legal research
Document drafting
Contract review
Discovery review
Court preparation
Case strategy
Preparing legal advice
Reviewing evidence
Drafting pleadings
Preparing client deliverables
Consulting analysis

Recruiting
Marketing
Business development
Internal reporting
Firm management
Internal software setup
Knowledge sharing

General research not tied to a client matter

Practice development
Company planning
Some non billable work may later support billable work indirectly, but it is not usually charged to a specific client.
Billable vs Non Billable Hours in Law Firms
Law firms need to separate billable and non billable time clearly because client billing depends on accurate time records.
Billable legal work
Reviewing a client contract, drafting a motion, preparing for a hearing, conducting matter research, reviewing discovery, joining a client call, or preparing negotiation strategy.
Non billable legal work
Internal training, general firm administration, marketing activities, recruiting interviews, internal knowledge sharing, practice group meetings, or updating internal templates.
Some activities can be either billable or non billable depending on the context. A meeting about a specific client matter may be billable. A general internal department meeting is usually non billable.
Why the Difference Matters
The difference between billable and non billable time matters because it affects revenue, profitability, staffing, pricing, and client transparency.
Firms need to know:
How much client work is being performed
How much work is being missed
How much time is spent on internal operations
Which clients or matters require the most effort
Whether pricing is realistic
Whether lawyers or professionals are overloaded
Whether too much time is being lost to administration
Without clear time tracking, a firm may not know whether it is profitable, efficient, or underbilling completed work.
Why Billable Time Gets Missed
Billable time often gets missed because work happens across too many places.
A lawyer may review a document, answer a matter related email, attend a calendar meeting, research a legal issue, and speak with a client, all before lunch. By the time the lawyer enters time, small tasks may be forgotten.
Time is entered too late
Manual timers are not started
Short calls are forgotten
Calendar meetings are not reviewed
Document work is not captured
Emails are reconstructed from memory
Descriptions are written too quickly
Lawyers switch between matters throughout the day
The firm relies on manual timesheets
Missed billable time is especially dangerous because the work was already done. The firm simply fails to capture it.
Why Non Billable Time Should Still Be Tracked
Some firms only focus on billable time, but non billable time also matters.
Tracking non billable time helps firms understand administrative workload, training investment, business development effort, internal management cost, software and process friction, recruiting time, operational inefficiency, utilization, and workload balance.
For example, if lawyers spend too much time on administrative work, the firm may need better processes, better staffing, or better tools.
Non billable time is not automatically bad. But if it is invisible, the firm cannot manage it.
Billable and Non Billable Time in Client Agreements
Whether time is billable often depends on the client agreement. Some clients allow certain types of work. Some clients restrict internal meetings, travel time, research time, administrative tasks, or communication between lawyers.
Some clients require task codes, activity codes, detailed descriptions, or outside counsel guideline compliance. This means two similar tasks may be treated differently depending on the client.
A law firm should always follow the client's billing rules and matter agreement.
Examples of Work That Can Be Either Billable or Non Billable
Some tasks are not automatically billable or non billable. Context matters.
Meetings | A client strategy meeting may be billable. A general internal team meeting is usually non billable. |
Research | Legal research for a client matter may be billable. General research for professional development is usually non billable. |
Emails | Matter related client emails may be billable. Internal administrative emails are usually non billable. |
Travel | Travel may be billable, partially billable, or non billable depending on the client agreement. |
Training | Client specific training required for a matter may be billable in some cases. General firm training is usually non billable. |
Billable vs Non Billable Hours and Utilization
Billable utilization measures how much working time is spent on billable work.
Weekly hours
40 total hours worked
Billable hours
28 hours are billable
Non billable hours
12 hours are non billable
Utilization rate 28 divided by 40 = 70 %
Utilization helps firms understand how time is being used, but it should be interpreted carefully. A high billable utilization rate can indicate strong client work. A low billable utilization rate can indicate too much administrative time, weak demand, poor staffing, or heavy investment in non billable initiatives.
Not all non billable time is waste. Some non billable work builds the firm.
