Key Takeaways
- The average law firm spends 45-50% of revenue on overhead, but most don’t know which practice areas are actually profitable after accounting for their true share of costs
- QuickBooks Class Tracking transforms basic accounting into strategic intelligence, allowing you to allocate overhead accurately and see real profitability by practice area, office, or attorney
- Implementing a weighted allocation model takes one afternoon but saves thousands annually by revealing hidden profit drains and opportunities you’re currently missing
Your corporate law partners just celebrated landing a Fortune 500 client with $2 million in annual billings. Meanwhile, your family law team quietly processed 200 cases generating $1.8 million.
Which practice area is more profitable?
If you’re like most mid-sized law firms, you honestly don’t know. Sure, you can see gross revenue by practice area. Maybe you even track direct costs like associate salaries. But what about the real overhead burden each practice carries? The corporate team’s heavy use of the law library? The family law department’s constant drain on administrative resources? The litigation group monopolizing the conference rooms?
Without accurate overhead allocation, you’re flying blind. You might be pouring resources into practice areas that look profitable but actually lose money once you factor in their true cost burden. According to recent industry analysis, law firms that properly allocate overhead discover that 20-30% of their “profitable” practice areas are actually underwater.
The good news? QuickBooks has powerful features hiding in plain sight that can solve this problem. Features that most law firms never use because they don’t know they exist or don’t understand how to configure them for legal practice.
This guide will show you exactly how to transform QuickBooks from a basic bookkeeping tool into a strategic profitability analyzer that reveals which practice areas truly drive your firm’s success—and which ones are secretly dragging you down.
The Hidden Cost Crisis in Law Firms
Before we dive into solutions, let’s understand the magnitude of the problem you’re solving.
The Shocking Reality of Law Firm Overhead
Recent studies paint a sobering picture:
- Average law firms spend between 45-50% of gross revenue on overhead
- Office rent alone consumes 9-12% of revenue
- Technology costs eat 4% of overhead (and rising)
- Turnover costs range from 30-150% of departed employee salaries
- Attorneys spend 40% of their time on non-billable administrative work
But here’s the real kicker: these costs don’t distribute evenly across your practice areas.
The Unequal Burden Problem
Consider this typical scenario in a mid-sized firm:
Corporate Law Division:
- Uses expensive research databases extensively
- Requires high-end conference facilities for client meetings
- Demands top-tier administrative support
- Occupies prime office space for partner offices
Family Law Division:
- Minimal research database usage
- Basic meeting room needs
- Shared administrative resources
- Efficient use of smaller offices
Yet if you’re like most firms, you’re either:
- Not allocating overhead at all (flying completely blind)
- Splitting overhead equally (corporate gets subsidized, family law gets penalized)
- Using outdated allocation methods that don’t reflect reality
This misallocation leads to catastrophic strategic errors: expanding “profitable” practice areas that actually lose money, cutting “unprofitable” areas that actually subsidize the rest of the firm, and setting billing rates based on fantasy rather than fact.
Understanding True Practice Area Profitability
The Profitability Equation
True practice area profitability isn’t just revenue minus direct costs. The complete formula is:
Practice Area Profit = Revenue – Direct Costs – Allocated Overhead
Where:
- Revenue = All fees collected from that practice area
- Direct Costs = Salaries, benefits, and specific expenses for that area
- Allocated Overhead = Fair share of firm-wide costs
Most firms stop at direct costs. That’s like calculating your personal wealth by counting only your salary and ignoring your mortgage, utilities, and taxes.
What Should Be Allocated?
Not all overhead should be allocated equally. Here’s how to think about different cost categories:
Fully Allocated Costs (spread across all practice areas):
- Rent and utilities
- General administrative staff
- Basic technology infrastructure
- Professional liability insurance
- Marketing (general firm)
Usage-Based Allocation (allocated based on consumption):
- Research databases (by actual usage)
- Conference rooms (by hours booked)
- Administrative support (by time tracked)
- Marketing (practice-specific campaigns)
Direct Assignment (charged to specific areas):
- Dedicated staff for one practice area
- Specialized software or databases
- Practice-specific marketing
- Travel and entertainment for specific matters
The QuickBooks Solution: Class Tracking Mastery
QuickBooks has a feature that’s perfect for overhead allocation but tragically underused: Class Tracking. Think of it as adding a third dimension to your accounting that reveals profitability insights invisible in standard reports.
What Is Class Tracking?
Class Tracking allows you to tag every transaction with a “class”—essentially a category that cuts across your normal account structure. While your Chart of Accounts shows what you spent money on, Classes show who or what areabenefited from that spending.
For law firms, Classes can represent:
- Practice areas (Corporate, Litigation, Family Law)
- Office locations (Downtown, Suburban, Virtual)
- Partner groups
- Client types (Corporate, Individual, Government)
- Or any combination through sub-classes
Why Classes Beat Everything Else
You might wonder: why not just use separate QuickBooks files, or customers/projects, or just more detailed accounts?
Classes are superior because they:
- Work across all transactions (unlike projects)
- Don’t complicate your Chart of Accounts
- Allow multiple categorization levels
- Generate instant profitability reports
- Integrate with your existing workflow
Most importantly, Classes let you maintain one set of books while viewing them through multiple lenses—exactly what you need for sophisticated overhead allocation.
Step-by-Step Setup Guide
Let’s transform your QuickBooks into a profitability powerhouse. This process takes about 2-3 hours initially but will save hundreds of hours annually.
Step 1: Enable Class Tracking
First, turn on the feature that’s been hiding in your QuickBooks all along:
- Click the Gear icon → Account and Settings
- Select Advanced tab
- Find the Categories section
- Toggle ONÂ Track classes
- Choose your tracking preference:
- One to entire transaction (simpler, good for starting)
- One to each row in transaction (more detailed, better for complex allocation)
- Check Warn me when a transaction isn’t assigned a class
- Save your settings
Pro tip: Always enable the warning. Unclassified transactions are the enemy of accurate profitability analysis.
Step 2: Design Your Class Structure
This is where strategy meets accounting. Your class structure should reflect how you think about your business.
Option A: Simple Practice Area Structure
- Corporate Law
- Litigation
- Family Law
- Real Estate
- Immigration
- Overhead (for unallocated costs)
Option B: Hierarchical Structure with Sub-Classes
- Corporate Law
- M&A
- Securities
- General Corporate
- Litigation
- Commercial
- Personal Injury
- Employment
- Family Law
- Divorce
- Custody
- Adoption
- Overhead
- Administrative
- Facilities
- Technology
Option C: Multi-Dimensional with Locations
Classes (Practice Areas):
- Corporate
- Litigation
- Family Law
Locations (Offices):
- Downtown
- Westside
- Virtual
Choose based on your reporting needs. You can always refine later, but simpler is usually better to start.
Step 3: Create Your Classes
- Go to Gear icon → All Lists → Classes
- Click New
- Enter your class name (e.g., “Corporate Law”)
- If using sub-classes, check Is sub-class and select parent
- Save and repeat for all classes
Critical Setup Tips:
- Create an “Overhead” or “Unallocated” class for shared costs
- Keep names short but clear (they appear on every transaction)
- If you have multiple offices, consider using Locations instead of (or with) Classes
- Document your structure for team training
Step 4: Configure Allocation Rules
Now comes the strategic part: deciding how to allocate overhead. Here’s a practical framework:
Create Allocation Tiers:
Tier 1 – Direct Assignment (100% to one class):
- Practice-specific salaries
- Dedicated software subscriptions
- Practice-specific marketing
Tier 2 – Usage-Based Allocation:
- Research databases (track by login/usage reports)
- Conference rooms (track by calendar bookings)
- Administrative support (track by timesheet)
Tier 3 – Headcount Allocation:
- General office rent
- Basic utilities
- General insurance
- Office supplies
Tier 4 – Revenue-Based Allocation:
- Firm-wide marketing
- Senior partner compensation
- Strategic initiatives
Document these rules in a simple spreadsheet:
| Expense Category | Allocation Method | Frequency | Notes |
|---|---|---|---|
| Rent | Headcount | Monthly | Based on FTE count |
| Westlaw | Usage report | Monthly | Export usage data |
| Marketing | Revenue % | Quarterly | Based on prior quarter |
| Admin salaries | Time tracking | Monthly | Use admin timesheets |
Implementing Your Allocation System
Month 1: Baseline Data Collection
Before you can allocate accurately, you need data. Start tracking:
Week 1-2: Transaction Classification
- Go through last month’s transactions
- Assign classes to all revenue and direct costs
- Leave overhead unallocated for now
- Run your first Profit & Loss by Class report
Week 3-4: Usage Tracking
- Set up tracking sheets for conference rooms
- Request usage reports from database vendors
- Have admin staff track time by practice area
- Document space usage by practice area
Month 2: Initial Allocation
Now apply your allocation rules using journal entries:
Example: Allocating $10,000 Monthly Rent
Headcount by practice area:
- Corporate: 5 attorneys
- Litigation: 3 attorneys
- Family Law: 2 attorneys
- Total: 10 attorneys
Journal Entry:
Debit: Rent Expense - Corporate Class $5,000
Debit: Rent Expense - Litigation Class $3,000
Debit: Rent Expense - Family Law Class $2,000
Credit: Rent Expense - Overhead Class $10,000
This moves the rent from your overhead class to practice areas based on headcount.
Pro tip: Create recurring journal entries for regular allocations. This automates the process going forward.
Month 3: Refine and Automate
Automation Strategies:
- Recurring Journal Entries: Set up monthly entries for stable allocations (rent, insurance)
- Default Classes: Assign default classes to vendors
- Westlaw → Corporate Law (if primary user)
- Office supplies → Overhead (to allocate later)
- Bank Rules: Create rules to auto-classify transactions
- Legal research charges → Appropriate class
- Utilities → Overhead for allocation
- Integrated Time Tracking: Use time tracking software that syncs with QuickBooks to automatically allocate based on billable hours
Advanced Allocation Strategies
The Weighted Allocation Method
Not all attorneys consume resources equally. A senior partner uses more resources than a first-year associate. Here’s how to account for that:
Create Weighting Factors:
- Senior Partner: 1.5
- Junior Partner: 1.25
- Senior Associate: 1.0
- Junior Associate: 0.75
- Paralegal: 0.5
Example Calculation: Corporate Division:
- 2 Senior Partners (2 × 1.5 = 3.0)
- 1 Junior Partner (1 × 1.25 = 1.25)
- 2 Senior Associates (2 × 1.0 = 2.0)
- Total weight: 6.25
If total firm weight is 20, Corporate gets 31.25% of overhead (6.25/20).
The Activity-Based Costing Approach
For maximum accuracy, track actual resource consumption:
- Identify Cost Drivers: What activities generate costs?
- Number of matters opened
- Court filings made
- Client meetings held
- Documents processed
- Track Activity Levels: Monitor these metrics by practice area
- Allocate Based on Activity:
- IT support costs based on help desk tickets
- Filing costs based on number of filings
- Reception costs based on client meetings
This requires more tracking but provides surgical precision in understanding true costs.
The Hybrid Model
Most successful firms use a hybrid approach:
- Simple allocation for stable costs (rent, insurance)
- Usage-based for variable costs (research, conference rooms)
- Activity-based for key drivers (administrative support)
- Direct assignment where possible (practice-specific expenses)
Reports That Reveal Hidden Profits
Once your system is running, QuickBooks can generate powerful insights:
The Essential Reports
1. Profit & Loss by Class
- Go to Reports → Profit & Loss by Class
- Shows revenue and expenses for each practice area
- Reveals true profitability after overhead allocation
2. Profit & Loss by Class YTD Comparison
- Compare current year to prior year
- Identify trends in practice area performance
- Spot growing or declining profitability
3. Class Listing Report
- Shows all transactions for specific class
- Perfect for drilling into problem areas
- Helps verify allocation accuracy
Custom Reports for Strategic Insights
Create a Profitability Dashboard:
- Revenue per Attorney by Class
- Total class revenue / Attorney FTE count
- Reveals productivity by practice area
- Overhead Percentage by Class
- Class overhead / Class revenue
- Shows efficiency of each practice area
- Profit Margin by Class
- (Revenue – All Costs) / Revenue
- The ultimate profitability metric
Monthly Review Metrics:
- Which practice area has the highest profit margin?
- Where is overhead percentage increasing?
- Which areas are trending up or down?
- Where should we invest or divest?
Common Pitfalls and How to Avoid Them
Pitfall 1: Over-Complicating the Structure
Symptom: 50+ classes, no one uses them correctly
Solution: Start with 5-7 main classes. You can always add detail later.
Pitfall 2: Inconsistent Application
Symptom: Half your transactions lack classes
Solution:
- Enable warnings for unclassified transactions
- Review weekly for the first month
- Create clear documentation
- Assign a “class champion” to monitor
Pitfall 3: Allocating 100% of Everything
Symptom: Senior partner compensation allocated to practice areas
Solution: Some costs should remain at firm level:
- Owner distributions
- Strategic investments
- Extraordinary items
- True firm-wide benefits
Pitfall 4: Set It and Forget It
Symptom: Using same allocation percentages for years
Solution:
- Review allocation basis quarterly
- Update for headcount changes
- Adjust for practice area evolution
- Annual allocation audit
Pitfall 5: Ignoring the Data
Symptom: Beautiful reports that no one reads
Solution:
- Schedule monthly profitability reviews
- Include in partner meetings
- Tie to compensation decisions
- Create action items from insights
Real-World Implementation Case Study
Let’s see how this works in practice:
Midwest Law Partners – 15 attorneys, 3 practice areas
Before Implementation:
- Thought corporate law was most profitable (highest revenue)
- Expanding corporate practice aggressively
- Family law considered “necessary but marginal”
After 6 Months of Overhead Allocation:
Shocking Discoveries:
- Corporate law profit margin: 12% (after true overhead)
- Litigation profit margin: 28%
- Family law profit margin: 34%
Why the Difference?
- Corporate consumed 60% of research database costs
- Required 2x administrative support hours
- Used prime office space inefficiently
- Generated higher overhead per dollar of revenue
Strategic Changes:
- Shifted marketing budget to family law
- Optimized corporate law overhead usage
- Renegotiated research subscriptions
- Relocated corporate team to reduce rent burden
Results After 1 Year:
- Overall firm profitability up 23%
- Corporate law margin improved to 22%
- Family law revenue increased 40%
- Made strategic decisions based on data, not assumptions

Conclusion: From Blindness to Insight
Most law firms operate like you’re driving at night with sunglasses on—you can see the road ahead dimly, but you’re missing critical details that could define your journey’s success or failure.
Proper overhead allocation in QuickBooks removes those sunglasses. Suddenly, you see which practice areas are highways to profitability and which are expensive dead ends. You understand why corporate law’s million-dollar revenues might be less valuable than family law’s “modest” fees. You can make strategic decisions based on facts, not partner politics or gut feelings.
The setup process takes one afternoon. The monthly maintenance takes two hours. But the insights you gain can transform your firm’s trajectory, potentially adding hundreds of thousands to your bottom line by revealing opportunities and threats invisible in standard financial statements.
Your competitors are likely still flying blind, making strategic decisions based on gross revenue or outdated assumptions. By implementing proper overhead allocation, you gain an information advantage that compounds over time.
The question isn’t whether you can afford to implement overhead allocation—it’s whether you can afford not to. Every month you operate without this visibility, you’re potentially pouring resources into losing propositions while starving your profit centers.
Start today. Enable Class Tracking. Create your structure. Begin allocating. Within 30 days, you’ll see your firm’s finances in a completely new light. Within 90 days, you’ll wonder how you ever managed without it.
FAQ: Overhead Allocation in QuickBooks
Q: Can I use QuickBooks Desktop instead of Online for class tracking?
A: Yes, QuickBooks Desktop has class tracking, but it lacks some features of Online. Desktop doesn’t support sub-classes as elegantly, has limited integration options, and makes it harder to access reports remotely. For modern law firms, QuickBooks Online’s collaboration features and integration capabilities make it superior for overhead allocation.
Q: How often should I update my allocation percentages?
A: Review quarterly, adjust annually. Major changes (adding/losing partners, opening/closing practice areas, significant headcount shifts) trigger immediate updates. Most firms find monthly allocations with quarterly reviews and annual overhauls work best.
Q: Should I allocate partner compensation to practice areas?
A: Generally, no. Partner draws and distributions are ownership returns, not operating expenses. However, if partners work primarily in specific practice areas, you might allocate their “salary equivalent” (what you’d pay a non-partner for that work) to get true practice area profitability.
Q: What if a practice area shows negative profitability?
A: Don’t panic or immediately shut it down. First, verify your allocation method is fair. Then consider: Is it strategic (loss leader)? Is it improving? Can overhead be reduced? Does it support other profitable areas? Give changes 6-12 months before making dramatic decisions.
Q: Can I track both practice areas AND offices with classes?
A: QuickBooks allows both Classes and Locations. Use Classes for practice areas and Locations for offices. This gives you two-dimensional analysis—see profitability by practice area, by office, or by practice area within each office.
Q: How do I handle overhead for attorneys working across multiple practice areas?
A: Three options: (1) Allocate based on time percentage in each area, (2) Assign attorneys to primary practice area only, (3) Create an “Interdisciplinary” class. Most firms use option 1 for accuracy, but it requires time tracking by practice area.
Q: Should I go back and reclassify historical transactions?
A: For initial benchmarking, classify 3-6 months of history—enough to see trends without overwhelming effort. Use QuickBooks’ Reclassify Transactions tool or export to Excel for bulk updates. Don’t go back more than one year unless required for specific analysis.
