Time recording software helps law firms create a reliable record of work performed for clients, internal operations, and other professional activities.
The category includes several different approaches:
This guide covers Manual time entry, Start-and-stop timers, Calendar-based capture, Passive activity capture, AI-assisted time-entry preparation, Timekeeping built into practice-management software, and Standalone timekeeping connected to finance systems.
A product should not be judged only by how many hours it captures.
The firm should evaluate whether the resulting entries are accurate, assigned to the correct matter, understandable to the client, compliant with billing rules, reviewable by the lawyer, and transferable to the existing billing environment.
What Is Time Recording Software?
Time recording software stores work as structured entries.
A legal time entry commonly contains:
Core time-entry field | Coding and workflow field |
Work date | Task code |
Timekeeper | Activity code |
Client | Source activity |
Matter | Approval status |
Duration | Release status |
Billable status | |
Description |
The software may capture some fields automatically and require the user to confirm others.
Time recording is an upstream function. Rates, prebills, invoices, accounting, eBilling, and collection may be handled by other systems.
Why Legal Time Recording Is Different
Law firm time recording must account for:
Client and matter confidentiality
Matter permissions
Approved timekeepers
Client-specific rates
Billing increments
Outside counsel guidelines
UTBMS codes
Block-billing restrictions
Billable and non-billable work
Alternative fee arrangements
Lawyer review
Audit and correction history
Finance-system integration
Many general workforce time tools lack the matter, confidentiality, coding, client-rule, and finance-integration controls required by law firms. Evaluate actual product capabilities rather than category labels.
Capture Methods
Manual Entry
The lawyer types the time entry directly.
Strengths
Simple
Direct user control
Low integration requirement
Suitable for unusual or offline work
Limitations
Easy to delay
Short tasks may be missed
Durations may be estimated
Descriptions may be vague
Matter and code selection may be inconsistent
Start-and-Stop Timers
The lawyer selects a matter and starts a timer.
Strengths
Direct elapsed-time measurement
Useful for focused work
Familiar workflow
Easy to understand
Limitations
Timer may not be started or stopped
Frequent matter switching creates effort
Overlapping timers require correction
Description and codes still need review
Calendar-Based Capture
The system turns calendar events into draft entries.
Strengths
Useful for meetings, hearings, and calls
Supplies participants and scheduled duration
Low additional user effort
Limitations
Scheduled time may differ from actual time
Not every event is billable
Event titles may disclose too much or too little
Unscheduled work remains missing
Passive Activity Capture
The system records activity from connected work tools.
Strengths
Captures fragmented work
Helps identify short tasks
Reduces dependence on memory
Provides a daily activity history
Limitations
Application activity is not necessarily focused time
Activity is not automatically billable
Matter classification may be uncertain
Privacy depends on the data collected
AI-Assisted Time Recording
AI may suggest:
Client and matter
Duration
Billable status
Description
Task and activity codes
Duplicate or unusual entries
Strengths
Reduces repetitive preparation
Supports consistent narratives
Can classify fragmented activity
Can prioritize exceptions
Limitations
Suggestions may be wrong
The system may infer unsupported details
Confidentiality and model use require review
Human approval remains necessary
Core Legal Features
Client and Matter Context
The software should support:
Matter data feature | Matter control feature |
Active and closed matters | Client-specific rules |
Clear matter names | Ethical walls |
Matter aliases | Matter permissions |
Responsible lawyer | |
Practice area | |
Billing arrangement |
Ask how the product handles several matters for the same client.
Lawyer Review
The lawyer should be able to:
View source activity
Change the matter
Adjust duration
Change billing status
Edit the narrative
Change codes
Split an entry
Merge related activity
Exclude personal or irrelevant work
Save a draft
Approve or release
The review interface should be efficient enough for daily use.
Narrative Support
Useful capabilities include:
Draft descriptions
Templates
Client-specific wording
Vague-language flags
Block-billing flags
Confidentiality prompts
Narrative-code consistency
Change history
The software should not invent legal work or strategy.
Billing Codes
Ask whether the product supports:
UTBMS task codes
Activity codes
Expense codes
Client-specific code sets
Matter phases
Required-code validation
Code suggestions
Code correction reporting
The final code should be confirmed by a person who understands the work.
Billable and Non-Billable Time
The software should record:
Billable
Non-billable
No charge
Pro bono
Administrative
Business development
Personal exclusion
Pending review
Capturing actual work before billing treatment can help the firm understand total effort and later adjustments.
Billing Increments
The system should support client-specific methods such as:
Six-minute increments
Fifteen-minute increments
Exact minutes
No minimum
No rounding up
Related short-task grouping
The product should distinguish actual captured duration from the final billing unit.
Duplicate and Overlap Detection
Test what happens when:
A meeting appears in the calendar and video platform
A timer runs during document activity
The same email is captured by two integrations
Two timers overlap
A user imports an existing entry
Several people attend the same meeting
An overlap is an exception for review, not automatic proof of improper billing.
Integration
A legal time recording system may need to connect with:
Microsoft Outlook
Microsoft Teams
OneDrive
iManage Work
Chrome
Practice-management software
Matter-management software
Billing and finance systems
Identity providers
Reporting platforms
Ask:
Is the connection native?
Which fields move?
Is synchronization one-way or two-way?
How are errors reported?
Which system owns the entry?
Is there an audit trail?
Is custom integration available?
How are API changes handled?
System Architecture
A common architecture is:
Lawyer works in approved systems.
Activity is captured.
Records are normalized and deduplicated.
Draft entries are prepared.
Matter, duration, narrative, and codes are suggested.
Rules flag exceptions.
Lawyer reviews.
Approved time is released.
Finance system applies rates and billing rules.
Billing team creates the prebill and invoice.
This separation prevents the time-recording product from being mistaken for a complete billing platform.
Privacy and Monitoring
Ask whether the product collects:
Metadata
Document titles
Document content
Email recipients
Email subjects
Email bodies
Browser URLs
Screenshots
Keystrokes
Application duration
Location
Personal activity
Also ask:
Can the firm limit sources?
Can users pause or exclude activity?
Who can see the raw activity?
Are source permissions respected?
Is data used for model training?
Where is data stored?
How long is it retained?
Can the firm delete it?
Are administrator actions audited?
Use the least intrusive capture method that meets the firm’s legitimate needs.
Security
Evaluate:
Access and protection control | Data lifecycle and resilience control |
Encryption | Backups |
Multi-factor authentication | Disaster recovery |
Single sign-on | Incident response |
Role-based access | Subprocessors |
Matter permissions | Data location |
Audit logs | Retention and deletion |
Data segregation | Export on termination |
Security claims should be supported by current documentation.
Reporting
Useful time-recording reports include:
Missing-time days
Submission lag
Draft backlog
Approved hours
Billable and non-billable hours
Matter corrections
Duration corrections
Narrative changes
Billing-code corrections
Duplicate and overlap exceptions
Excluded activity
Entries released by period
Timekeeper and matter trends
Broader realization and collection reports require billing and accounting data.

Frequently Asked Questions
What is time recording software for law firms?
It is software that stores legal work as client- and matter-based time entries, often using manual entry, timers, passive capture, or AI assistance.
Is time recording software the same as billing software?
No. Time recording prepares and approves time entries. Billing software applies rates and creates prebills and invoices.
Should law firms use passive time recording?
Passive capture can help with fragmented work, but the firm should evaluate privacy, matter accuracy, duration, personal exclusion, and lawyer review.
What integrations should time recording software support?
Common needs include email, calendars, Microsoft Teams, document management, matter management, and the firm’s finance or billing system.
Is MIRA a full legal billing platform?
No. MIRA focuses on time capture, entry preparation, lawyer review, and release to supported finance systems.
