Time and Billing Software for Attorneys: One System or Two?
Should a law firm run time and billing software for attorneys as one combined system, or keep its billing system and add a separate timekeeping layer on top?

AI Summary
Timekeeping records work performed on client matters, while billing converts those records into invoices. Both steps can happen inside one system or across connected systems.
An all-in-one practice management system keeps the workflow under one login, but the completeness of each entry depends on the timekeeping process available inside that platform.
A separate timekeeping layer can generate entries from work activity and sync finished records into the firm’s underlying practice management system.
Billing rules can be applied when an entry is created and again at pre-bill, while standardized codes and exchange formats carry billing data between firms and clients.
Choosing the wrong architecture for time and billing software for attorneys can create unnecessary disruption without improving the quality of the entries that reach the invoice. The practical choice is whether the firm’s existing platform already runs the timekeeping workflow it needs, or whether a dedicated layer should generate complete entries and send them into the billing system already in place.
What Is Time and Billing Software for Attorneys?
Timekeeping and billing are two closely related processes.
Timekeeping records the work attorneys perform on client matters, including the time spent, the relevant client and matter, and a description of the activity.
Billing turns those records into invoices, applying the firm's rates, billing arrangements, and client requirements.
Most law firms already have a PMS that manages clients, matters, and billing. The question is whether its built-in timekeeping functionality is sufficient to capture a complete and accurate record of the work performed.
Modern AI timekeeping software addresses that gap by automatically generating draft time entries from attorneys' work activity, without requiring firms to replace their existing billing systems.
Built-In PMS Timekeeping vs. a Dedicated AI Timekeeping Platform
Built-in PMS timekeeping | Dedicated AI timekeeping platform | |
|---|---|---|
Time capture | May rely on manual entries and timers | Automatically generates entries from work activity |
Completeness | Less sophisticated, targeted features | Helps identify activities that might otherwise be missed |
Attorney effort | Attorneys create and describe entries | Attorneys review automatically generated drafts |
Pre-bill review | Depends on the PMS's available functionality and workflows | Specialized tools help identify issues and coordinate review |
Integration | Native to the PMS | Connects directly to the existing PMS |
Billing | Managed in the PMS | Continues in the firm's existing PMS |
How a Dedicated AI Timekeeping Platform Works With Your Existing PMS
A dedicated AI timekeeping platform adds advanced time capture capabilities to the software a firm already uses.
Rather than requiring a complete system replacement, the platform integrates with the existing PMS, using its client and matter information to generate time entries that can be submitted directly to the firm's billing workflow.
The process is straightforward:
Work is recorded automatically. AI identifies legal activity across emails, documents, calendars, calls, and meetings.
Draft time entries are generated. The platform suggests the relevant client, matter, time spent, and billing narrative.
Attorneys review and submit. Lawyers confirm the entries rather than creating each one manually.
Entries flow into the existing PMS. Approved time records are transferred through the integration, ready for the firm's established billing process.
For firms using supported integrations, this avoids manual exports, duplicate data entry, or replacing the systems already used by finance and operations teams.
PointOne Time, for example, integrates with established legal practice management and billing systems, including Clio, Aderant, Elite 3E, SurePoint, LeanLaw, QuickBooks, MyCase, Juris, Filevine, Actionstep, TimeSolv, Tabs3, Orion, CosmoLex, and RocketMatter.
The PMS remains the firm's billing system, while the dedicated AI timekeeping tool improves the completeness and accuracy of the time records it receives.
How Integrated Pre-Bill Review Reduces Administrative Work
Capturing time is only the first step. Before invoices reach clients, billing teams and supervising attorneys must review entries for accuracy, consistency, and compliance with billing requirements.
When timekeeping and pre-bill review involve disconnected tools and manual processes, corrections can require additional emails, follow-ups, and coordination between attorneys and finance teams.
A dedicated platform that connects timekeeping with pre-bill review makes this process more efficient.
More Complete Entries From the Start
PointOne Time generates draft entries from attorneys' actual work activity, with suggested client and matter assignments and billing descriptions.
Attorneys review prepared entries instead of reconstructing their work from memory.
This gives billing teams a more complete starting point and reduces the need to investigate missing or unclear information later.
Faster Review Across Teams
Pre-bill review often involves several people: the attorney who performed the work, billing specialists checking the entries, and partners responsible for approving the bill.
PointOne Review helps centralize this process, identifying potential issues such as vague narratives, block billing, duplicate entries, and inconsistencies across timekeepers.
Rather than manually reviewing every entry to find potential problems, billing teams can focus on those that require attention.
Connecting time capture with pre-bill review gives teams greater visibility into the underlying time records and reduces unnecessary back-and-forth between attorneys and billing staff.
A Simpler Path to Billing
Once time entries have been reviewed and released, they flow into the firm's existing PMS for billing.
The firm retains its established billing infrastructure while benefiting from automated time capture and a more streamlined review process.
There is no need to migrate to an entirely new practice management platform or duplicate the work already handled by the PMS.
FAQs about Time and Billing Software for Attorneys
Does AI timekeeping software replace a law firm's PMS?
No. Dedicated AI timekeeping software can integrate with an existing PMS, generating and submitting time entries while the firm's established system continues to manage billing and invoicing.
Is integrating AI timekeeping software with a PMS complicated?
Modern AI timekeeping platforms offer native integrations with widely used legal practice management systems. With a supported connection, client and matter information can be synchronized and reviewed time entries can flow directly into the existing billing workflow, avoiding manual transfers or a full system migration.
What are the benefits of dedicated AI timekeeping software?
A dedicated platform can help law firms capture more billable work, reduce manual time entry, improve the quality of billing narratives, and streamline coordination between attorneys and billing teams.
How does AI improve pre-bill review?
AI-assisted pre-bill review helps identify potentially vague narratives, duplicate time, block billing, and other inconsistencies before invoices are finalized. This allows billing teams to focus on exceptions rather than manually inspecting every entry.
What Happens When No Native Connector Exists?
A CSV export and import workflow can transfer entries until a native connector is available. The firm exports the finished records from the timekeeping application and imports them into its practice management system.
Are Billing Rules Checked Differently in Each Architecture?
The architecture does not change the need for entry-level and pre-bill checks. Individual entries can be checked for issues such as missing codes or prohibited terms, while pre-bill review identifies problems visible only across multiple entries.
