Professional Services Accounting & Bookkeeping
Accounting outsourcing for law firms, consulting firms, agencies and other fee-billed practices, covering client trust ledgers, three-way reconciliation, work-in-progress, retainers and partner accounts.
What tends to make Professional Services accounting different
Professional-services firms may need reporting that connects time, matter or project data from practice-management systems with the accounting ledger. Unbilled time and work in progress should be tracked and reported according to the firm’s approved accounting policy; recorded time does not automatically become a recognised asset or revenue. Retainers and advance fees also need to be recorded and released using the firm’s documented treatment. For firms holding client funds, trust records must remain separate from operating funds and be reconciled to individual client balances under the requirements that apply in the relevant jurisdiction. Accounting support can maintain the records, prepare schedules and flag exceptions, while the firm retains decisions about accounting policy, client-money authorisations, regulatory compliance and final review.
The Same Books, Read by Different People
The mechanics overlap and the reporting does not. The scope is shaped around which of these you are.
Law firms
Client money and matter-level workFirms holding client money need records that distinguish client balances from operating funds and support reconciliation between the bank, trust control account and individual client ledgers. The applicable review and recordkeeping requirements vary by jurisdiction; accounting support can prepare the records and identify exceptions for the firm’s review.
- Client trust and operating activity recorded separately using the firm’s approved account structure
- Three-way reconciliation schedules prepared for firm review, with exceptions identified
- Client disbursements and recoverable costs tracked apart from firm expense
- Matter-level billing and WIP schedules prepared from approved records and reconciled using the firm’s accounting policy
- Retainers and advance fees recorded using the firm’s approved accounting treatment
Consulting firms
Fee-billed engagementsFee-billed engagements can span several reporting periods. Useful schedules connect approved time and project records with invoices, costs and receipts, while the treatment of unbilled work follows the firm’s accounting policy.
- Work-in-progress schedules prepared using the firm’s approved accounting policy
- Write-offs recorded explicitly, so realisation is visible
- Project costing and the general ledger agreed to one basis
- Subcontractor payables and expense recharges processed
- Profitability reporting by engagement, client or practice area
Agencies and studios
Retainers and pass-through costAgency records may include supplier costs that are recharged to clients as well as costs incurred for the agency’s own operations. The classification and presentation depend on the contract and the accounting policy approved by the responsible accountant.
- Client-recharged supplier costs identified separately using the agency’s approved accounting treatment
- Retainers and advance fees recorded using the agency’s approved accounting treatment
- Freelance and supplier payables processed and coded to the job
- Job-level cost tracking tied back to the monthly accounts
- Month-end close and management reporting on your cadence
The parts of the workflow that can be delegated

Four Things That Go Wrong in Professional Services Books
Not because anyone was careless. Because each one is a convention a generalist bookkeeper has no particular reason to know, and the accounts look reasonable while it is wrong.
Work in progress that lives in the practice management system only
Time recorded but not yet invoiced is an asset, and in most firms it exists only in the time-tracking tool while the ledger knows nothing about it. The result is a P&L that shows the cost of delivering work in one month and the revenue from it in another, and a balance sheet missing one of the firm's largest assets. Bringing WIP into the ledger on a consistent basis is what makes monthly results comparable.
Write-offs that disappear into revenue
When time is written off at billing, the reduction usually just lowers the invoice, so realisation is invisible in the accounts. The work still cost what it cost. Recording the write-off explicitly is what lets anyone see the gap between what was worked and what was recovered, which for most firms is the number that matters most.
Retainers and advance fees recognised on receipt
A retainer received is not fee income until the work is done. Booking it to revenue on receipt inflates the period it arrives in and empties the one the work lands in, and it hides a real obligation to the client. The liability has to be carried and released as it is earned.
Projects and periods that never reconcile
Project profitability and monthly accounts drift apart when project costs are tracked in one system and posted in another without a common basis. Both are then right and they disagree, which usually ends with someone maintaining a third spreadsheet. Agreeing one basis at setup is cheaper than reconciling two forever.
What We Would Put Right First
Before anything is optimised, these have to be true. Most of them are setup decisions that are cheap now and expensive to retrofit.
- Work in progress brought into the ledger on a consistent basis
- Write-offs recorded explicitly so realisation is visible
- Retainers and advance fees carried as liabilities and released as earned
- Project costing and the general ledger agreed to one basis
- Disbursements and recoverable client costs tracked separately from firm expense

Frequently Asked Questions
Do you handle client trust and IOLTA bookkeeping for law firms?
We keep client trust and operating funds separate in the accounting records, maintain each client balance by matter, and prepare the three-way reconciliation of the bank balance, trust ledger and total client balances. Any difference is reported for your review. Your firm remains responsible for regulatory compliance; client-money rules vary by jurisdiction and are set by the relevant bar association or regulator.
What exactly is a three-way reconciliation, and who does it?
Compare the trust bank balance, the trust ledger control account and the total of the individual client balances for the same date. We can prepare the reconciliation and identify exceptions for your firm to review. The required review, evidence, frequency and sign-off depend on the rules that apply in your jurisdiction.
Can you move money between the trust and operating accounts?
Banking control remains with the client and is not part of the accounting workflow, and on client money the line is absolute — every transfer is initiated and authorised by your firm. We record it, reconcile it and tell you if the supporting detail does not hold up.
Can you track work-in-progress and unbilled time?
Yes. We can prepare WIP and unbilled-time schedules from approved time and matter reports, then reconcile them to billing and ledger records. Whether an amount is recognised as an asset or revenue depends on the firm’s accounting policy and the underlying engagement terms; we follow the firm’s documented treatment and flag missing or inconsistent records.
How do you handle retainers and advance fees?
The treatment depends on the retainer agreement, the nature of the fee and the firm’s approved accounting policy. We record receipts and prepare supporting schedules using the firm’s documented instructions; the responsible accountant determines when amounts are recognised as revenue or remain deferred.
Do you handle partner draws and distributions?
Partner capital accounts can be maintained and record draws and distributions as the partners agree them, working alongside your CPA on the tax treatment. We do not advise on partner compensation, profit-sharing or capital arrangements — we keep the accounts that follow from what is decided.
Can you report profitability by matter, project or client?
Yes, provided project costing and the general ledger are agreed to one basis. Where they are tracked in separate systems without that, both are right and they disagree, which usually ends with somebody maintaining a third spreadsheet. Agreeing the basis at setup is cheaper than reconciling two forever.
What kinds of firms do you work with?
Law firms, consulting firms, agencies and studios, and similar practices that bill for time or for fee-based engagements. The mechanics overlap — WIP, write-offs, retainers, pass-through cost — but what each one is read on differs, so the scope is shaped around which you are.
What records support matter or project profitability reporting?
Useful inputs may include approved time records, billing and matter or project reports, client-cost details, expense records and the chart-of-accounts or allocation rules. The reporting basis should be agreed with the firm so the practice-management view and general ledger can be reconciled rather than maintained as two unexplained totals.
Can you prepare recurring close schedules inside our existing practice-management and accounting systems?
Where permissions and the agreed task list allow it, preparation can use the existing practice-management reports, ledger exports and workpaper templates. The scope should identify which records are authoritative, how WIP or retainers are tied out, who reviews exceptions and which decisions remain with the firm; software configuration or migration is not implied.
