Key Considerations When Implementing a New Legal Billing System

Implementing a new legal billing system is a major shift for any legal department. Whether you're upgrading from a legacy platform or transitioning from manual invoice tracking, the process impacts everything from day-to-day efficiency to long-term cost control.

Here’s what you need to consider when introducing a new legal billing system to your team.

1. Know What You’re Solving For

Before selecting a platform, be clear about your department’s goals. Are you trying to:

• Enforce billing guidelines more consistently?

• Reduce invoice review time?

• Track budgets more accurately?

• Improve law firm accountability?

Let your business needs, not the tool, drive your decision. A good billing system should align with your strategy and eliminate specific pain points, not add new complexity.

2. Engage Key Stakeholders Early

One of the biggest mistakes teams make is excluding those who actually use the system day-to-day. Legal ops may lead the implementation, but it’s critical to include:

• Attorneys (approvers and reviewers)

• Finance or accounting teams

• Outside counsel administrators

  
  

Early input ensures the system meets everyone's needs and builds internal support for adoption.

3. Configure, Don’t Just Install

Too many teams rely on default settings. Every legal department is different, your billing system should reflect that.

Focus on:

• Custom invoice routing rules by matter type, practice group, or amount

• Automated billing guideline enforcement

• Budget tracking thresholds and notifications

• Custom accounting or matter fields tied to your finance systems

• Clear invoice status visibility for internal and external users

  
  

Lawmetrics Tip: Thoughtful configuration is the difference between a tool that works, and one that drives people back to spreadsheets.

4. Test Real Workflows Before You Launch

While testing doesn’t need to dominate your timeline, it’s essential to make sure your team can:

• Submit and review invoices easily

• Trigger the correct routing workflows

• Enforce billing rules as intended

• Pull accurate reports tied to your KPIs

  
  

This is where you catch issues before they become system-wide frustrations. Even a small amount of real-user testing can dramatically reduce post-launch cleanup.

5. Train by Role, Not Just Function

Generic system training is a missed opportunity. Tailor your sessions based on user needs:

• Legal approvers need speed and clarity

• Legal ops teams need reporting and enforcement tools

• Outside counsel need to know exactly what will get an invoice rejected

  
  

The more confident your users are, the smoother your adoption will be.

6. Launch With a Plan for Ongoing Optimization

A billing system isn’t a “set it and forget it” tool. Build in regular checkpoints post-launch to:

• Review performance (invoice cycle time, rejection rates, etc.)

• Capture user feedback

• Revisit your workflows and guidelines as your department evolves

  
  

Your billing system should grow with you—not hold you back.
