Professional Services CPA for Law Firms, Medical Groups, and Agencies.
Partner compensation, client trust accounting, cash versus accrual elections, and succession. GreenGrowth CPAs is an AICPA member firm, PCAOB registered, and serves clients nationwide from eight offices.
Talk to a Specialist Law Firm Trust AccountingProfessional service firms carry accounting problems that most operating businesses never meet. Owners take profit rather than salary, so compensation planning drives the tax outcome. Revenue arrives as time and billings rather than product sales, which makes work in progress and unbilled receivables central to the balance sheet. Many firms also hold money that belongs to someone else.
California law firms face a specific obligation. Under California Rule of Court 9.8.5 and State Bar Rules title 2, division 1, rule 2.5, licensees must register every IOLTA and non-IOLTA client trust account annually, complete a self-assessment, and certify compliance with rule 1.15 of the Rules of Professional Conduct. The deadline matches the annual licence fee deadline. The State Bar began mandatory compliance reviews in August 2025, and a firm selected for review must engage a State Bar-approved CPA at its own expense.
GreenGrowth CPAs was founded in 2016 and is headquartered at 200 Spectrum Center Drive in Irvine, California. The firm serves law firms, medical and dental groups, engineering and architecture practices, consulting firms, marketing agencies, financial advisers, and veterinary practices, with tax, audit, outsourced CFO, and succession services under one roof.

Why It Is Different
The Owners Are the Product. That Changes the Accounting.
In most businesses the owner and the revenue engine are separable. In a professional service firm they are the same thing. Partners generate the fees, take the profit, hold the client relationships, and carry the value a buyer would eventually pay for. Three consequences follow.
Compensation drives the tax outcome
Guaranteed payments, profit distributions, retirement contributions, and reasonable compensation each land differently on a partner's return. A structure that suits two partners rarely suits twelve with unequal origination. Get it wrong and partners overpay tax, underfund retirement, and start arguing about the split.
Work in progress is a real asset
Time worked but not yet billed sits between your effort and your cash. Firms on cash basis often carry substantial unbilled value that never appears on a statement. That distorts every profitability read and every valuation conversation. Any lender, buyer, or incoming partner will ask about it.
Some of the money is not yours
Law firms hold client funds. Medical groups handle patient deposits and insurance recoveries. Agencies pass media spend through their accounts. Money held for someone else needs segregation, reconciliation, and a paper trail, and the rules governing it sit outside standard GAAP.
What We Bring
Six Things Professional Firms Ask Us For.
Guaranteed payment and profit allocation modelling, reasonable compensation analysis, and retirement contribution planning across the partner group.
Method analysis against your gross receipts and entity type, plus the accounting method change filing where a switch makes sense.
Trust account bookkeeping and monthly three-way reconciliation between the bank statement, the trust ledger, and individual client ledgers.
Margin by service line, by matter, and by originating partner, so compensation conversations start from numbers rather than impressions.
Valuation support and diligence readiness for incoming partners, retiring partners, and external buyers, planned years ahead rather than weeks.
Employee benefit plan audits once a firm passes 100 plan participants, and R&D credit studies for engineering and architecture practices.

California Law Firms
Client Trust Accounting Under CTAPP.
The State Bar of California runs the Client Trust Account Protection Program. Under California Rule of Court 9.8.5 and State Bar Rules title 2, division 1, rule 2.5, nearly every California licensee completes an annual cycle alongside their licence renewal. Since August 2025 the State Bar also selects firms for a compliance review.
What CTAPP requires each year
- Register every IOLTA and non-IOLTA account open at any point in the period
- Report the December 31 year-end balance for each account
- Complete a self-assessment of trust account management practices
- Certify compliance with rule 1.15 of the Rules of Professional Conduct
The deadline matches your annual licence fee due date. Firms can register accounts on behalf of their attorneys through the State Bar's Agency Billing application.
Compliance reviews began in August 2025
A selected firm engages a State Bar-approved CPA at its own expense, and the review examines records rather than intentions.
Reviewers look at whether clients were notified within 14 days of funds arriving, whether undisputed funds went out within 45 days, whether the trust accounting records are complete, and whether monthly three-way reconciliations were actually performed.
Where GreenGrowth CPAs fits
We handle the accounting a review examines. That means trust account bookkeeping, monthly three-way reconciliation between the bank statement, the trust ledger, and the individual client ledgers, and the documentation supporting your annual certification.
Your designated licensee under rule 2.5(E) still carries the duty, since that rule requires them to perform or supervise the reconciliation personally. We make sure the records behind it hold up.
Conducting a CTAPP compliance review is a separate engagement type, and the State Bar maintains its own approved list for it. Attorneys grossing under a stated threshold may request an in-house State Bar review instead of engaging an outside CPA. Confirm current requirements with the State Bar, since the programme continues to develop.
Trust account reconciliations behind schedule?
Incomplete records are what a compliance review finds. Getting current takes weeks, not days, so the time to start is before you are selected.
Who We Serve
Professional Practices Across the Spectrum.
The accounting problems rhyme across these verticals, but the details do not. A dental group consolidating locations, an architecture practice claiming R&D credits, and a law firm reconciling client trust accounts each need something different.
By Practice Type
What Each Practice Type Actually Needs.
Four requirements come up repeatedly, and each has a different trigger.
| Requirement | Who It Hits | What Triggers It |
|---|---|---|
| Client trust accounting | Law firms, title agencies, some medical groups | Holding funds that belong to a client or third party. For California attorneys, CTAPP registration and certification run annually. |
| Employee benefit plan audit | Any firm sponsoring a 401(k) or 403(b) | Reaching 100 or more participants with account balances at the start of the plan year, subject to the 80-120 rule. |
| R&D tax credit study | Engineering, architecture, software consulting | Design work resolving technical uncertainty. Many firms qualify and never claim it, because a generalist preparer is not looking. |
| Audited or reviewed statements | Firms borrowing, recapitalising, or selling | A lender covenant, an investor, or a buyer's diligence request. A review often satisfies the requirement at lower cost than an audit. |

Common Questions
Professional Services CPA FAQs.
How the accounting differs
How is accounting different for professional service firms?
Three things set it apart. Owners take profit rather than salary, so compensation structure drives the tax result more than any other decision. Revenue comes from time and billings, which puts work in progress and unbilled receivables at the centre of the balance sheet in a way product businesses never see. And many professional firms hold money belonging to clients or third parties, which needs segregation and reconciliation outside standard GAAP. The chart of accounts, the reporting cadence, and the tax strategy all follow from those three.
What is partner compensation planning and why does it matter?
Partner compensation planning covers how owners get paid: guaranteed payments, profit distributions, retirement contributions, and reasonable compensation where a professional corporation is involved. Each lands differently on a partner's return. A structure that works for two partners with equal origination rarely works for twelve partners with unequal books. Handled well, it ties pay to performance and keeps tax friction low. Handled badly, partners overpay tax, underfund retirement, and start disputing the split.
Should our firm be on cash or accrual basis?
Many professional service firms qualify for cash basis, which defers tax until fees are collected and usually suits a firm with lumpy collections. Accrual gives a truer picture of performance, which matters when a lender, an incoming partner, or a buyer is reading the statements. Some firms run cash for tax and accrual internally for management reporting. The right answer depends on your gross receipts, your entity type, and what you are planning in the next few years. Changing method requires an accounting method change filing, so it pays to decide deliberately rather than drift.
Client trust accounts and CTAPP
What is CTAPP and who has to comply?
CTAPP is the Client Trust Account Protection Program run by the State Bar of California. Under California Rule of Court 9.8.5 and State Bar Rules title 2, division 1, rule 2.5, nearly every California licensee must annually register each IOLTA and non-IOLTA client trust account open at any point in the reporting period, report the December 31 year-end balance, complete a self-assessment of trust account practices, and certify compliance with rule 1.15 of the Rules of Professional Conduct. The deadline matches the annual licence fee due date. Law firms can register accounts on behalf of their attorneys through the State Bar's Agency Billing application.
What happens in a CTAPP compliance review?
The State Bar began mandatory compliance reviews in August 2025. A selected firm engages a State Bar-approved CPA at its own expense, and the reviewer examines records rather than intentions. The areas covered include whether clients received notice within 14 days of funds arriving, whether undisputed funds were distributed within 45 days, whether trust accounting records are complete, and whether monthly three-way reconciliations were performed. Attorneys grossing under a stated threshold may request an in-house State Bar review instead. Confirm current requirements and thresholds with the State Bar, since the programme continues to develop.
Can GreenGrowth CPAs help with our trust accounts?
Yes, on the accounting side. We handle client trust account bookkeeping, monthly three-way reconciliation between the bank statement, the trust ledger, and individual client ledgers, and the supporting documentation behind your annual certification. That is the record a compliance review examines. Conducting the CTAPP compliance review itself is a separate engagement type, and the State Bar maintains its own approved list for it. Your designated licensee under rule 2.5(E) retains the duty either way, since that rule requires them to perform or supervise the monthly reconciliation personally.
Growth, audits, and exit
When should a professional service firm consider an outsourced CFO?
Usually at a complexity threshold rather than a revenue number. Multiple partners with different origination, more than one location, a lender relationship with covenants, or a planned transaction each create questions a bookkeeper cannot answer. An outsourced CFO delivers forecasting, partner reporting, profitability analysis by service line or matter, and financial leadership in the room for major decisions, without the cost of a full-time hire.
Does our firm's retirement plan need an audit?
Generally once the plan reaches 100 or more participants with account balances at the start of the plan year. At that point the Form 5500 must carry a report from an independent qualified public accountant. The 80-120 participant rule gives one exception: a plan sitting between 80 and 120 participants may file in the same category it used the previous year. Professional firms often cross the threshold through hiring or a merger without anyone flagging it. GreenGrowth CPAs is a member of the AICPA Employee Benefit Plan Audit Quality Center.
How do you value a professional services firm for sale or transition?
Valuation usually starts from a multiple of revenue or EBITDA, then adjusts for the things a buyer actually worries about: client concentration, how much revenue depends on one or two partners, retention risk after the transaction, the mix of recurring versus project work, and growth trajectory. Law firms, medical practices, and consulting firms each carry their own conventions. The factors that move the number take years to change, which is why succession planning that starts three to five years out produces a materially better outcome than a rushed sale.
