Law Firm Bookkeeping Cost: What to Expect
Updated November 2025
Law firm bookkeeping costs between $500 and $2,500 per month, with most firms paying $750 to $1,500 for comprehensive legal bookkeeping that includes trust account management. The wide range reflects differences in firm size, transaction volume, trust account complexity, and whether the provider specializes in legal accounting. Generic bookkeepers charge less but rarely deliver the compliance oversight law firms require.
According to Clio’s 2023 Legal Trends Report, firms that maintain structured financial systems grow faster and retain clients longer.
Understanding cost starts with knowing what bookkeeping for law firms actually includes.
What Drives Law Firm Bookkeeping Pricing
Five factors determine what you'll pay for bookkeeping services:
Firm Size and Transaction Volume
Solo practitioners with straightforward finances fall on the lower end of the range. Multi-attorney firms with higher transaction volumes, multiple bank accounts, and complex partner distributions require more time and command higher fees. The number of monthly transactions directly impacts reconciliation time and reporting complexity.
Trust Account Activity
Firms holding client funds need IOLTA compliance oversight - monthly three-way reconciliation, client ledger maintenance, and documentation that satisfies bar requirements. High-volume trust activity (frequent deposits, disbursements, and client matters) increases scope significantly. A firm processing 10 trust transactions monthly has different needs than one processing 100.
Current State of Books
Clean, well-organized books cost less to maintain than messy ones. Firms with backlogged reconciliations, incomplete records, or years of deferred maintenance need bookkeeping cleanup before ongoing service begins. Cleanup projects typically run $1,500 to $5,000+ depending on severity, billed separately from monthly retainers.
Software and Systems
Firms using legal practice management software like Clio or MyCase integrated with QuickBooks streamline bookkeeping workflows. Firms with disconnected systems, manual processes, or no existing software require more setup time and ongoing effort.
Provider Specialization
Generic bookkeepers charge $300-$600/month but lack legal-specific expertise. Legal bookkeeping specialists charge $750-$2,500/month but deliver trust accounting compliance, bar-ready documentation, and reporting designed for law firm decision-making. The premium reflects specialized knowledge, not just higher rates.

These ranges assume ongoing monthly service with reasonably organized books. Firms needing significant cleanup, system setup, or catch-up work should expect higher initial costs before settling into standard monthly retainers.
What Should Be Included at Each Price Point
Not all bookkeeping retainers deliver equal value. Here's what to expect at different investment levels:
Basic Tier ($500-$750/month)
Operating account reconciliation
Credit card reconciliation
Expense categorization
Monthly profit & loss statement
Basic balance sheet
This tier works for solo practitioners without trust accounts or with minimal trust activity. It covers fundamental bookkeeping but lacks the compliance infrastructure most law firms need.
Standard Tier ($750-$1,250/month)
Everything in Basic, plus:
Trust account reconciliation (monthly)
Three-way reconciliation documentation
Client trust ledgers
Trust-specific reporting
Accounts receivable tracking
Cash flow visibility
This tier suits most solo and small firms holding client funds. It delivers the compliance foundation required for IOLTA trust accounting while providing financial clarity for business decisions.
Premium Tier ($1,250-$2,500/month)
Everything in Standard, plus:
Multiple trust account management
Practice area profitability reporting
Attorney productivity metrics
Cash flow forecasting
Budget variance analysis
Partner distribution tracking
Dedicated bookkeeper relationship
This tier serves growing firms with complex operations, multiple partners, or high-volume trust activity. The investment supports both compliance and strategic financial management.
The Hidden Cost of Cheap Bookkeeping
Generic bookkeepers charging $300-$500/month seem cost-effective until you calculate what's missing.
What Generic Providers Skip:
Three-way reconciliation (they don't know how)
Client trust ledgers (they've never built one)
IOLTA compliance documentation (they don't understand the requirements)
Trust-specific reporting (their software isn't configured for it)
Bar audit preparation (they won't know what auditors need)
What That Costs You:
A firm came to us after discovering their $400/month bookkeeper hadn't reconciled their trust account in 14 months. No client ledgers existed. Three-way reconciliation had never been performed. The trust accounting violations weren't intentional - the bookkeeper simply didn't know the requirements.
Cleanup cost: $4,200
Time to remediate: 3 months
Stress during bar audit preparation: immeasurable
The $350/month "savings" over a legal specialist cost $4,200 in cleanup plus ongoing compliance risk. That math doesn't work.
What Bookkeeping Should NOT Cost
Some providers overcharge for basic services or pad retainers with unnecessary complexity. Watch for these warning signs:
Excessive Hourly Billing
Monthly retainers work better than hourly billing for ongoing bookkeeping. Hourly arrangements create unpredictable costs and incentivize inefficiency. If your bookkeeper bills hourly, ask why - and whether a retainer makes more sense.
Charging Extra for Basic Reports
Monthly financial statements (P&L, balance sheet, cash flow) should be included in any retainer. Providers charging separately for each report are nickel-and-diming you.
Requiring Expensive Software You Don't Need
QuickBooks Online ($30-90/month) handles most law firm needs when configured correctly. Providers pushing expensive enterprise software for small firms may be earning referral fees rather than solving problems.
Unclear Scope Definitions
If your provider can't clearly articulate what's included versus extra, expect surprise charges. Get scope in writing before signing.
Monthly Retainer vs. Hourly: Which Makes Sense
Monthly Retainer Advantages:
Predictable costs for budgeting
Provider incentivized to build efficient systems
Encourages proactive communication (no meter running)
Scales with firm growth
When Hourly Might Work:
Project-based cleanup with defined end date
Consulting on specific issues
Firms with highly variable monthly activity
For ongoing law firm bookkeeping, monthly retainers almost always make more sense. They align provider incentives with your interests: efficient, accurate work that prevents problems rather than billing to fix them.
DIY vs. Outsourced: True Cost Comparison
Some attorneys handle their own bookkeeping to save money. Here's the real math:
DIY Bookkeeping Costs:
Attorney time: 5-10 hours/month
At $250/hour billing rate: $1,250-$2,500/month in opportunity cost
Software: $50-100/month
Risk of errors: unquantified but real
Stress and distraction: significant
Outsourced Bookkeeping Costs:
Monthly retainer: $750-$1,500
Your time: 1-2 hours/month reviewing reports
Risk of errors: lower (if using specialist)
Stress: minimal
The math is clear: DIY bookkeeping costs more than outsourcing when you account for attorney time value. The only scenario where DIY wins is if your time has no alternative use - which isn't true for practicing attorneys.
When to Re-Evaluate What You're Paying
Your bookkeeping needs change as your firm evolves. Re-evaluate your arrangement when:
You've Outgrown Your Provider
Signs include: reports arriving late, questions going unanswered, errors increasing, or your bookkeeper seeming overwhelmed. Growth requires systems that scale.
Your Trust Activity Has Increased
More client matters means more trust transactions. If your bookkeeper handled 20 trust transactions monthly and now you're at 80, the scope has changed significantly.
You're Preparing for a Major Event
Bringing on a partner, seeking financing, or planning an exit all require clean, well-documented books. Investment in bookkeeping quality pays dividends during due diligence.
You Haven't Reviewed Pricing in 2+ Years
Costs and services evolve. If you're paying the same rate you negotiated three years ago, you may be overpaying for outdated service or underpaying for inadequate support.
You've Had Compliance Issues
Trust accounting red flags or bookkeeping mistakes signal system failures. Fixing the immediate problem without upgrading ongoing support invites recurrence.
Questions to Ask Before Hiring
Before committing to a bookkeeping provider, get clear answers:
Do you specialize in law firms? Generic providers won't understand trust accounting requirements.
How do you handle trust account reconciliation? The answer should include three-way reconciliation, client ledgers, and monthly documentation.
What's included in the monthly retainer? Get specifics: which accounts, which reports, what frequency.
What's NOT included? Understand where extra charges apply.
What software do you use and support? Ensure compatibility with your existing systems.
How do you communicate? Monthly calls? Email only? Dashboard access?
What happens if I have questions between reporting periods? Understand response time expectations.
Can you provide references from other law firms? Talk to current clients about their experience.
Getting the Right Fit
The right bookkeeping investment balances cost against risk and value. Underpaying leaves you exposed to compliance failures, messy books, and strategic blindness. Overpaying wastes resources that could fuel growth.
For most law firms holding client funds, $750-$1,500/month delivers appropriate compliance oversight and financial clarity. Firms with complex operations or growth ambitions may justify premium investment. Solo practitioners without trust accounts can operate at lower price points - but should ensure even basic providers understand legal-specific requirements.
The question isn't just what bookkeeping costs. It's what inadequate bookkeeping costs when compliance failures, missed insights, or audit surprises arrive. Investing appropriately in specialized law firm bookkeeping reports and systems prevents problems that cost far more to fix than to prevent.
