Key Takeaways:
- Law firms collect only 91% of invoiced work on average, with the median collection lockup lasting 27 days—representing nearly a month of revenue trapped in accounts receivable
- Regular AR aging report reviews can identify collection problems early, with studies showing that invoices over 90 days past due have less than a 50% chance of being collected
- Firms using automated AR tracking and systematic review processes collect 49% more monthly revenue per lawyer compared to those relying on manual methods
Picture this: You’re reviewing your firm’s financials and discover $250,000 in outstanding invoices, some dating back six months. That’s not just numbers on a spreadsheet—it’s payroll, overhead, and growth opportunities sitting in someone else’s bank account. If this scenario sounds familiar, you’re not alone. The average law firm has 27 days of revenue locked up in collections at any given time, and 9% of invoices never get paid at all.
Here’s the kicker: Most of these collection problems are entirely preventable. The secret weapon? A simple report that many firms either ignore or review haphazardly—the accounts receivable aging report. When used correctly, this humble document transforms from a boring spreadsheet into a cash flow crystal ball, revealing which clients pay promptly, which need gentle reminders, and which might be heading toward write-off territory.
But let’s be honest. Most law firms treat AR aging reports like they treat their gym memberships—good intentions, sporadic attention, and a vague sense of guilt about not using them properly. The difference is that ignoring your AR aging report costs a lot more than that unused gym membership. We’re talking about real money that could be funding your firm’s growth, paying bonuses, or simply ensuring you sleep better at night.
This guide will show you exactly how to review your AR aging reports effectively, spot problems before they become disasters, and implement systems that keep cash flowing predictably into your firm. Whether you’re using legal billing software or still tracking invoices in Excel, these principles will help you collect more of what you’ve earned.
What Exactly Is an AR Aging Report (And Why Should You Care)?
An accounts receivable aging report might sound like something only accountants get excited about, but it’s actually one of the most powerful tools in your financial arsenal. Simply put, it’s a snapshot of all the money clients owe you, organized by how long those invoices have been outstanding.
Think of it as a health checkup for your firm’s cash flow. Just as a doctor uses vital signs to assess your physical health, the AR aging report reveals the financial vital signs of your practice. It categorizes your outstanding invoices into time buckets—typically:
- Current (0-30 days): Fresh invoices still within payment terms
- 31-60 days: Starting to age but still recoverable
- 61-90 days: Getting concerning, requiring attention
- Over 90 days: Red alert territory
For law firms, this report carries extra weight because of the unique nature of legal billing. Unlike businesses that can repossess products or cancel services, once you’ve provided legal services, you can’t take them back. That makes proactive AR management not just important—it’s essential for survival.
The report answers critical questions like:
- Which clients consistently pay late?
- Are certain practice areas experiencing more collection issues?
- Is your overall AR trending up or down?
- Which invoices need immediate attention?
According to data from Clio’s Legal Trends Report, firms that actively manage their AR using aging reports collect 2.3 hours’ worth of invoiced work per day, compared to those who don’t systematically track collections. That might not sound like much, but over a year, it represents hundreds of thousands of dollars in additional revenue.
The State of Law Firm Collections: A Reality Check
Before diving into how to review your AR aging report, let’s establish some benchmarks. Understanding where your firm stands compared to industry averages helps identify whether you’re dealing with minor inefficiencies or major problems.
The Numbers Don’t Lie
Recent industry data paints a sobering picture of law firm collections:
- Average collection rate: 91% (meaning 9% of billed work never gets paid)
- Median collection lockup: 27 days of revenue sitting in AR
- Invoices over 90 days: Less than 50% chance of collection
- Average time lawyers spend on collections: 10% of their workday
But here’s where it gets interesting. These averages hide significant variations based on firm size and practices:
- Solo practitioners: 90% collection rate, 20 days lockup
- Small firms (2-4 attorneys): 90% collection rate, 30 days lockup
- Mid-sized firms (5-19 attorneys): 95% collection rate, 27 days lockup
- Large firms (20+ attorneys): 96% collection rate, fewer lockup days
The message is clear: Larger firms with dedicated AR management collect more efficiently. But that doesn’t mean smaller firms are doomed. It means they need to be smarter about how they review and act on their aging reports.
The Cost of Ignoring AR
When firms neglect their AR aging reports, the consequences compound quickly:
- Cash flow crunches: Can’t pay expenses despite showing profit on paper
- Increased borrowing: Financing operations instead of collecting earned fees
- Client relationship damage: Aggressive last-minute collection attempts
- Staff morale issues: Uncertainty about bonuses and raises
- Lost opportunities: Can’t invest in growth or technology
One study found that 68% of companies receive more than half their payments after the due date. For law firms operating on thin margins, this delay can be the difference between thriving and merely surviving.
Anatomy of an Effective AR Aging Report
Not all AR aging reports are created equal. While the basic structure remains consistent, the most useful reports for law firms include specific elements that make review and action more efficient.
Essential Components
Your AR aging report should include:
Client Information:
- Client name and matter number
- Primary contact information
- Responsible attorney
- Practice area
Invoice Details:
- Invoice number and date
- Original amount
- Current balance
- Payment terms
Aging Buckets:
- Current (0-30 days)
- 31-60 days
- 61-90 days
- 91-120 days
- Over 120 days
Summary Metrics:
- Total AR by aging category
- Percentage of total AR in each bucket
- Average days to payment by client
- Historical payment patterns
Customization for Law Firms
Generic AR reports miss crucial elements for legal practices. Your report should also track:
- Matter type: Litigation vs. transactional work ages differently
- Fee arrangement: Hourly vs. fixed fee vs. contingency
- Trust account balances: Available retainer funds
- Payment history: Client’s historical payment behavior
- Collection notes: Previous contact attempts and responses
If you’re using alternative cloud-based legal practice management software, ensure it can generate reports with these law firm-specific fields. The extra detail transforms a basic aging report into an actionable collection tool.
Visual Indicators
The best AR aging reports use visual cues to highlight issues:
- Color coding for aging categories (green for current, red for 90+ days)
- Trend arrows showing whether individual ARs are improving or worsening
- Exception highlighting for accounts exceeding credit limits
- Dashboard summaries for at-a-glance assessment
Red Flags: What to Look for in Your Aging Report
Reviewing an AR aging report isn’t just about identifying old invoices. It’s about spotting patterns that predict future collection problems. Here are the warning signs that demand immediate attention:
Client-Specific Red Flags
The Perpetual Promiser: Client always at 60-90 days with excuses
- Pattern: Consistent aging just before write-off territory
- Action: Require larger retainers or payment plans
The Disputer: Every invoice triggers questions or complaints
- Pattern: High volume of adjustments or credits
- Action: Improve pre-billing communication and documentation
The Ghost: No response to invoices or collection attempts
- Pattern: Aging rapidly with no client contact
- Action: Escalate to partner level or consider collection agency
The Partial Payer: Sends token payments to stay barely current
- Pattern: Growing balance despite regular small payments
- Action: Stop work until account is brought current
Systemic Red Flags
Beyond individual clients, watch for these firm-wide patterns:
Aging Concentration: If 20% of clients represent 80% of old AR
- Indicates over-reliance on problematic clients
- May need to revisit client acceptance procedures
Practice Area Disparities: Certain practice groups with consistently higher aging
- Could indicate billing practice issues
- May need specialized collection approaches
Seasonal Patterns: Predictable spikes in aging during certain months
- Often seen in practices with cyclical work
- Requires proactive communication before busy seasons
New Client Syndrome: Recent clients immediately falling behind
- Suggests problems with initial expectation setting
- Review engagement letter and retainer policies
According to the Washington State Auditor’s office, increasing aged receivables can indicate employee theft through “lapping” schemes. While rare, this highlights why regular review by multiple people is important.
Best Practices for Regular AR Review
Reviewing your AR aging report shouldn’t be a year-end fire drill. The most successful firms make it a regular rhythm, like a financial heartbeat that keeps cash flowing steadily.
Optimal Review Frequency
Weekly Quick Scans (15 minutes):
- Focus on 90+ day accounts
- Check for new additions to 60+ day buckets
- Verify expected payments were received
Monthly Deep Dives (1-2 hours):
- Full review of all aging categories
- Trend analysis comparing to prior months
- Update collection strategies for problem accounts
Quarterly Strategic Reviews (Half day):
- Analyze patterns across practice areas
- Review and update collection policies
- Set targets for AR reduction
Who Should Be Involved
Creating an AR review team ensures multiple perspectives and shared accountability:
Managing Partner: Strategic decisions on problem accounts Billing Attorney: Insight into specific client relationships Office Manager: Day-to-day collection activities Accounting Staff: Technical accuracy and trend analysis
For smaller firms, these roles might overlap, but the key is having both relationship and financial perspectives represented.
The Review Meeting Agenda
Structure your AR review meetings for maximum efficiency:
- Dashboard Review (5 minutes):
- Total AR and trends
- Collection rate changes
- Wins from previous period
- Problem Account Review (20 minutes):
- Accounts over 90 days
- New additions to 60+ day buckets
- Specific action plans for each
- Process Improvements (10 minutes):
- What’s working well
- Recurring issues to address
- Policy changes needed
- Action Items (5 minutes):
- Who does what by when
- Follow-up schedule
- Success metrics
Documentation and Follow-Up
The best review process means nothing without follow-through. Document:
- Decisions made about specific accounts
- Collection strategies attempted
- Client communications and responses
- Payment arrangements agreed upon
Modern practice management systems can track these notes directly in the client record, making historical information instantly accessible during future reviews.
Leveraging Technology for Better AR Management
While you can review AR aging reports manually, technology transforms the process from a chore into a strategic advantage. Here’s how modern firms are using automation to collect faster and with less effort.
Benefits of Automated AR Tracking
Real-Time Visibility: No waiting for month-end reports
- Dashboard showing current AR status
- Instant alerts when accounts hit aging thresholds
- Mobile access for partners on the go
Intelligent Reminders: Automated but personalized
- Customized email sequences based on aging
- Escalation paths for non-responsive clients
- Integration with client preferred communication methods
Predictive Analytics: Spot problems before they occur
- Machine learning identifies payment pattern changes
- Risk scoring based on client history
- Early warning system for potential defaults
According to recent studies, 91% of mid-sized firms with fully automated AR systems report increased savings, cash flow, and growth. More compelling: firms using payment plans collect 49% more monthly revenue per lawyer.
Integration with Practice Management
The real power comes from connecting AR aging data with other firm systems:
- Time and billing: See unbilled WIP alongside AR
- CRM: Access complete client relationship history
- Document management: Link invoices to matter documents
- Trust accounting: Apply retainer balances automatically
This integration means you’re not just looking at numbers—you’re seeing the complete client financial picture.
Choosing the Right Tools
When evaluating AR management technology, prioritize:
- Ease of use: Complex systems won’t get adopted
- Customization: Law firm-specific workflows
- Reporting flexibility: Create the views you need
- Integration capabilities: Works with existing systems
- Mobile accessibility: Review and approve anywhere
Many firms find that embracing an era without traditional law practice management software and instead choosing best-of-breed solutions for specific functions like AR management yields better results than monolithic systems.
Turning Insights into Action: Collection Strategies
The most detailed AR aging report is worthless without action. Here’s how to translate what you learn into improved collections.
The Graduated Response System
Different aging buckets require different approaches:
Current (0-30 days):
- Thank you for recent payment (if applicable)
- Gentle reminder if approaching due date
- Offer convenient payment options
31-60 days:
- Personal email from billing attorney
- Phone call to discuss any issues
- Offer payment plan if appropriate
61-90 days:
- Letter from managing partner
- Discussion about work stoppage
- Final opportunity for payment arrangement
Over 90 days:
- Formal demand letter
- Work cessation notice
- Collection agency evaluation
Client Communication Best Practices
How you communicate about AR matters as much as when:
Be Proactive: Don’t wait for problems
- Send invoices immediately upon completion
- Include detailed descriptions of work performed
- Communicate regularly during matter progress
Be Professional: Maintain the relationship
- Assume good intentions initially
- Listen to client concerns
- Document all communications
Be Persistent: Consistency gets results
- Follow up every 7-10 days
- Use multiple communication channels
- Escalate appropriately
Studies show that 78% of executives believe better communication could have resolved payment disputes. Make sure your collection efforts strengthen rather than strain client relationships.
Policy Improvements Based on AR Analysis
Your aging report reveals policy gaps. Common improvements include:
- Larger retainers: For clients with poor payment history
- Progress billing: For long-term matters
- Credit limits: Maximum AR before work stops
- Payment plans: Formal arrangements for large balances
- Early payment incentives: Discounts for prompt payment
Remember, the goal isn’t just to collect past due amounts—it’s to prevent future aging through better policies and procedures.
Common Pitfalls and How to Avoid Them
Even well-intentioned firms stumble when implementing AR aging review processes. Here are the most common mistakes and how to sidestep them:
Pitfall 1: Inconsistent Review Schedule
Problem: Reviews happen “when we get around to it” Result: Problems compound and become harder to solve Solution: Calendar recurring review meetings and treat them as non-negotiable
Pitfall 2: Focusing Only on Dollar Amounts
Problem: Ignoring small balances from habitual late payers Result: Bad habits spread and administration costs mount Solution: Review by percentage overdue, not just absolute dollars
Pitfall 3: Lack of Follow-Through
Problem: Great discussions, no action Result: Clients learn that deadlines are meaningless Solution: Assign specific owners and deadlines for every action item
Pitfall 4: One-Size-Fits-All Approach
Problem: Treating all clients and matters the same Result: Damaging good relationships while being too soft on problems Solution: Segment clients and customize approaches based on history
Pitfall 5: Waiting Too Long to Escalate
Problem: Hoping problems will resolve themselves Result: Lower collection probability and higher costs Solution: Clear escalation triggers based on aging buckets

The Bottom Line: Your Money Is Waiting
Here’s the truth: Thousands of dollars currently sitting in your AR aging report should be in your bank account. The only thing standing between you and that money is a systematic approach to reviewing and acting on your aging data.
The statistics are clear. Firms that regularly review their AR aging reports and take consistent action collect more money, faster, with less stress on client relationships. They sleep better knowing their cash flow is predictable and their financial future is secure.
But perhaps most importantly, effective AR management frees you to focus on what you do best—practicing law. Instead of wondering if you can make payroll or fund that new initiative, you’ll have confidence that the money you’ve earned will actually arrive.
Your AR aging report isn’t just a financial document. It’s a roadmap to better cash flow, stronger client relationships, and a more successful practice. The question isn’t whether you should be reviewing it regularly—it’s whether you can afford not to.
Ready to transform your firm’s financial health? Start with your next AR aging report review. Set aside an hour, gather your team, and begin turning those outstanding invoices into cash. Because every day you wait is another day your money sits in someone else’s account.
The best time to improve your AR management was six months ago. The second-best time is today.
FAQ
Q: How often should we really review our AR aging report? A: At minimum, conduct a thorough review monthly, with quick weekly scans of accounts over 60 days. Larger firms or those with cash flow concerns should review weekly. The key is consistency—sporadic reviews are almost as bad as no reviews.
Q: What’s an acceptable collection rate for a law firm? A: Aim for 95% or higher. The industry average is 91%, but top-performing firms achieve 96-98%. If you’re below 90%, you have significant room for improvement. Remember, every percentage point represents thousands in lost revenue.
Q: Should we write off old receivables or keep trying to collect? A: Generally, write off receivables over 180 days unless you have active payment arrangements or special circumstances. The cost of collection often exceeds the likely recovery. However, consult your accountant about timing for tax purposes.
Q: How do we handle AR reviews for different practice areas? A: Create separate aging reports by practice area, as collection patterns vary significantly. For example, litigation matters often have longer payment cycles than transactional work. Tailor your collection strategies and timing expectations accordingly.
Q: What’s the best way to prevent AR problems in the first place? A: Strong upfront practices prevent most AR issues: Clear engagement letters, adequate retainers, regular billing, detailed invoices, and consistent client communication. An ounce of prevention truly is worth a pound of cure in AR management.
Q: Should partners be responsible for collecting their own AR? A: Hybrid approach works best. Partners maintain client relationships and have strategic input, but dedicated staff handle routine follow-up. This balances relationship preservation with consistent collection efforts.
Q: How do we know if we need AR management software? A: If you’re spending more than 2 hours weekly on AR management, struggling to get timely reports, or your collection rate is below 90%, technology will likely pay for itself quickly through improved collections.
Q: What’s the biggest mistake firms make with AR aging reports? A: Treating them as historical documents rather than action tools. The report should drive immediate activities, not just document problems. Every line over 60 days should have an associated action plan and owner.
