A law firm can be profitable on paper and still feel short of cash every month.
That apparent contradiction is familiar to many Managing Partners. The firm is busy, fee earners are billing and the management accounts show a healthy profit. Yet salaries, tax, supplier payments and partner drawings still create pressure on the bank balance.
The issue is often not a lack of work. More commonly, the problem lies in law firm cashflow and the gap between earning profit and actually collecting cash — a gap the profession’s own benchmarking confirms is still wide, even in a strong year. The Law Society’s 2026 Financial Benchmarking Survey, compiled annually by Hazlewoods LLP from over 120 firms, found total lock-up (WIP and debtors combined) at 134 days on average — down from 146 the year before, but still just over four months between doing the work and being paid.
Why profit does not always mean strong law firm cashflow
Profit is an accounting measure. Cash is what the firm can actually use to pay its obligations.
A profitable practice may still have substantial amounts tied up in work in progress, unpaid invoices or unrecovered disbursements. Slow billing can also delay the point at which completed work turns into income.
Tax liabilities and partner drawings add further pressure if they are not aligned with real cash generation. As a result, a firm may look profitable while its available cash remains under strain.
In practice: we worked with a litigation-heavy firm whose management accounts showed a healthy 22% net margin, yet the partners were routinely delaying drawings by six to eight weeks each quarter. The underlying cause turned out to be almost entirely lock-up related — WIP on two large matters had been left unreviewed for over four months. Once those matters were billed and a monthly WIP review was introduced, the firm was able to restore normal drawings within one quarter, with no change to profitability.
Where profitable firms often lose visibility
Monthly accounts are useful, but they do not always explain what is happening operationally.
A Managing Partner may know turnover, expenses and net profit, yet still have limited visibility over WIP, aged debt, billing delays and upcoming cash commitments.
This is where stronger management reporting becomes valuable. We believe partners should be able to see how quickly work moves from WIP to bill, how quickly invoices turn into cash and where money is becoming trapped. Without that visibility, cashflow pressure can feel unpredictable even when the underlying causes are measurable.
The benchmark picture: what the profession’s own data shows
The Law Society survey tracks more than lock-up alone, and the wider picture is useful context for any Managing Partner assessing their own numbers:
Measure (2026 survey, YoY)
2025 figure
2026 figure
Total lock-up (WIP + debtors)
146 days
134 days
Chargeable hours per fee earner
752
807
Non-salary overheads as % of income
31%
28.4%
Even in a year where the sector recorded its strongest fee growth in over 15 years, lock-up — while improving — remained the single most persistent drag identified in the survey. That’s a useful sanity check: strong revenue growth on its own does not resolve a cash timing problem, and the two need to be managed separately.
Lock-up can hide behind healthy revenue
Revenue alone does not tell the full story.
A department may report strong fees while holding a large amount of unbilled WIP. Another may bill promptly but experience slow collections. Both can create pressure on cash.
For that reason, we look beyond headline turnover and focus on the full path from work completed to cash received. That includes billing speed, debtor days, unbilled disbursements, write-offs and the time partners take to approve draft bills.
A firm that understands its lock-up position — and how it compares to the sector median of 134 days — can usually make better decisions about recruitment, drawings and investment.
Compliance and commercial performance should support each other
Legal finance is sometimes split into two separate conversations: compliance and commercial performance.
In practice, the two should reinforce one another. Accurate legal cashiering, timely reconciliations and reliable client account records improve confidence in the wider financial information used by the firm.
The SRA Accounts Rules require firms handling client money to maintain accurate accounting records and complete reconciliations regularly. Strong control over those processes supports both regulatory compliance and better financial decision-making. When the underlying data is dependable, reporting becomes more useful.
Are Clio and Xero giving partners the information they need?
Many firms already use systems such as Clio and Xero, yet continue to rely heavily on spreadsheets for decision-making.
That can mean useful data already exists but is not being presented in a way that helps partners act. A properly configured reporting process should help the firm understand billing performance, debt, WIP, cash collections and matter profitability.
The objective is not to create more reports. It is to provide a concise view of what needs attention and why. For example, if billing is slowing, the issue should be visible before month-end. If one department is growing revenue but consuming cash, partners should be able to see that pattern early.
Five questions every Managing Partner should be able to answer
A useful finance review should make a handful of commercial questions easy to answer.
How much work is currently sitting in WIP? How quickly are invoices turning into cash? Which practice areas generate the strongest cashflow? Are partner drawings aligned with actual cash availability? Is the firm converting fee-earner capacity into billable work effectively?
If those questions cannot be answered with confidence, the firm may not have a profitability problem at all. It may have a reporting problem.
When fractional CFO support adds value
As a law firm grows, finance becomes less about recording transactions and more about interpreting them.
Partners need to know whether the firm can afford to recruit, whether a new office is viable and which practice areas deserve further investment. They also need to understand whether pricing protects margin and whether current cash generation can support planned growth.
Those questions require more than bookkeeping or year-end accounts. They require accurate information, timely analysis and commercial interpretation. This is where fractional CFO support can add value, particularly for firms that are not ready to recruit a full-time finance director.
Turning profit into usable cash
Improving cashflow does not always require higher revenue.
Often, the fastest gains come from improving billing speed, WIP management, credit control and forecasting. Better use of Clio and Xero can also help partners understand where cash is being generated and where it is getting stuck.
When those processes work together, the firm gains a clearer view of its financial position and can make decisions with more confidence.
At AM Strategic, we help UK law firms improve management reporting, strengthen legal finance processes, optimise Clio and Xero, and provide fractional CFO support.
If your firm is profitable on paper but cash still feels under pressure, book a consultation with AM Strategic to review where cash is being delayed and how your finance function can provide better control.
Frequently Asked Questions
1. Why can a profitable law firm still run out of cash? Because profit does not always arrive as cash immediately. Money may be tied up in WIP, unpaid invoices, disbursements or other timing differences.
2. What is lock-up in a law firm? Lock-up is the time between completing work and receiving payment. It usually includes both unbilled WIP and unpaid invoices.
3. What is the current average lock-up for UK law firms? The Law Society’s 2026 Financial Benchmarking Survey found average total lock-up of 134 days, down from 146 the previous year, based on data from over 120 firms across England and Wales.
4. What should law firms monitor to improve cashflow? Firms should monitor WIP, billing turnaround, aged debt, cash collections, disbursements, write-offs and forward cash requirements.
5. Can Clio and Xero help improve law firm cashflow? Yes, if the systems are configured and reported on properly. They can help firms improve visibility over WIP, billing, debt and business performance.
6. When should a law firm consider fractional CFO support? Fractional CFO support can be useful when partners need stronger forecasting, management reporting and commercial insight but do not yet need a full-time finance director.
