Law Firm Bookkeeping Cost: What to Expect
Updated April 2026
Law firm bookkeeping cost depends on the scope and complexity of the firm’s accounting—not attorney count alone. Transaction volume, trust-account activity, billing and accounts receivable, payroll or accounts payable support, software setup, cleanup needs, and reporting requirements can materially change the work involved.
Accounting Atelier uses custom fixed-fee pricing after reviewing the firm’s books and workflow.
What does bookkeeping cost for a 3–5 attorney law firm?
Among the provider prices reviewed for this guide in August 2026, published examples for small and multi-attorney law firms range from about $800 per month into the low $2,000s, while a broader integrated accounting package reaches $2,500 per month. These figures provide market context; they are not Accounting Atelier prices, and the included scopes are materially different.

These are dated third-party examples, not Accounting Atelier pricing or promises. Their scopes, firm profiles, setup work, tax services, payroll support, reporting, and advisory components differ. Buyers should compare included work before comparing fees.
Understanding your costs starts with understanding what law firm accounting actually involves - from trust compliance to financial reporting to matter-level tracking.

What Does the Monthly Fee Actually Include?
Not all monthly fees cover the same scope. Before comparing quotes, confirm whether the following are included or billed separately:
Typically included in full-service legal bookkeeping: Monthly bank reconciliation (operating and trust accounts). Three-way trust reconciliation. Transaction categorization and recording. Monthly financial statements (profit and loss, balance sheet, cash flow statement). Trust accounting reports with per-client balances. Year-end 1099 preparation support.
Sometimes included, sometimes billed separately: Payroll processing. Accounts payable management. Bill payment processing. Sales tax filing. Year-end tax package preparation for your CPA.
Rarely included in base bookkeeping fees: Tax preparation and filing (CPA scope). Financial advisory or CFO-level strategy. Audit representation. Practice management software setup or migration.
The same quoted fee can represent materially different work. Confirm whether the proposal includes operating-account reconciliation, trust-accounting support, financial statements, billing or accounts receivable, payroll or accounts payable support, software setup, cleanup, tax-preparation support, and reporting.
Also confirm which services require separate scope and how material changes in transaction volume, trust activity, or workflow complexity would affect the fee.
Pricing is one signal. If you are evaluating bookkeepers more broadly, here is the framework I would use to choose one for my own firm.
What Drives the Cost Higher?
The main scope factors are transaction volume, trust-account activity, billing and accounts receivable, payroll or accounts payable support, software setup, cleanup needs, reporting requirements, and the complexity of the firm’s existing books and workflow.
Trust account complexity. More clients in trust means more per-client ledgers to track and reconcile. A firm with 50 active client trust balances requires more bookkeeping time than a firm with 5.
Transaction volume. The more deposits, disbursements, and operating expenses flowing through your accounts each month, the more time categorization and reconciliation require. Firms that process credit card payments through trust (which creates merchant fee complications) add another layer.
Multiple entities. Firms with separate PLLCs, holding companies, or multi-state entities need separate books for each entity, which multiplies the scope.
Cleanup backlog. If you are switching providers or starting with months of unreconciled transactions, the initial cleanup costs more than ongoing maintenance. This is a one-time cost, not recurring.
How Much Does Law Firm Accounting Software Cost?
Your bookkeeper's monthly fee does not include the cost of the software they work inside. Here are the 2026 monthly costs for common law firm accounting stacks:
QuickBooks Online only: $38/month (Simple Start) to $275/month (Advanced). This is the accounting engine. If you are using QBO for your general ledger without a practice management integration, expect your bookkeeper to spend more time on manual data entry, which may increase their fee. See QuickBooks for law firms for setup details.
Clio Manage + QBO: Clio starts at $49/month per user (EasyStart). Combined with QBO, a solo attorney's software cost is approximately $87 to $125/month before the bookkeeper's fee. Clio Accounting launched in 2026 and adds built-in accounting for $29/user/month, which may reduce or eliminate the need for a separate QBO subscription for some firms.
MyCase + QBO: MyCase starts at $49/month per user (Basic). Combined with QBO, a solo attorney's software cost is similar to the Clio stack. See MyCase Accounting review for how the integration handles trust data.
CosmoLex (all-in-one): Starts at approximately $99/month per user. CosmoLex includes practice management, billing, and trust-compliant accounting in one platform, eliminating the need for a separate QBO subscription. The trade-off is less flexibility and a smaller pool of bookkeepers who specialize in the platform.
LeanLaw + QBO: LeanLaw adds legal-specific trust accounting on top of QBO for approximately $60 to $80/month. Combined with QBO, a solo attorney's software cost runs $98 to $155/month.
Total monthly cost for a solo attorney (software + bookkeeping): approximately $700 to $1,000/month. For a small firm: $1,200 to $2,000/month including software licenses for all users.
For a breakdown of what each billing platform costs, see Best Legal Billing Software for Law Firms (2026).
Is It Cheaper to Do Your Own Law Firm Bookkeeping?
Whether DIY bookkeeping is less expensive depends on the complete workload, not only the absence of a bookkeeping fee. Consider attorney and staff time, software setup, transaction volume, monthly review, correction work, reporting, and any trust-account responsibilities.
DIY bookkeeping may be workable when the books are simple, activity is limited, and the person doing the work understands the firm’s accounting obligations. When a firm holds client funds, the decision should also address who will maintain the required records, complete the applicable reconciliation process, investigate discrepancies, and provide documentation when requested.

Confirm what each proposal includes before comparing fees.
-
Full-service legal bookkeeping typically includes monthly bank reconciliation for operating and trust accounts, three-way trust reconciliation, transaction categorization, monthly financial statements (P&L, balance sheet, cash flow), trust accounting reports with per-client balances, and year-end 1099 support.

QuickBooks Online costs $38 to $275 per month depending on the plan. Adding a practice management integration (Clio at $49+/month, MyCase at $49+/month, or LeanLaw at $60-80/month) brings the total software cost to $87 to $155 per month for a solo attorney.
