Why Law Firms Need to Pay Attention to Their Profit and Loss
A profit and loss statement (P&L) shows your firm’s revenue, expenses and profit over a period of time. For law firms, the value is in the trends: which practice areas and attorneys drive revenue, whether overhead is creeping up, and why a profitable month can still leave you short on cash.
What Does a Law Firm P&L Show?
A P&L lists your firm’s revenue, its operating expenses, and the profit left over. Operating expenses include payroll, rent, software, insurance, and marketing.
For most firms, payroll is the largest expense by far. Small changes in staffing or compensation have a big effect on profit, so it pays to watch payroll closely.
What Should Attorneys Look For on the P&L?
Revenue trends. Compare month over month and year over year. A single month rarely tells the whole story.
Revenue by practice area or attorney. This requires books that are set up to track it, using classes or locations in QuickBooks, or a connection to your practice management software. See: Clio & QuickBooks Bookkeeping.
Overhead creep. Watch for expenses growing faster than revenue.
Profit margin. How much of each dollar the firm keeps, and whether that’s improving.
Why a Profitable P&L Can Still Mean a Cash Crunch
Profit and cash aren’t the same thing. Depending on how your books are kept, revenue may be recorded before it’s collected, which is especially common with contingency fees. Owner draws, loan payments, and client cost advances all use cash but don’t show up as P&L expenses.
That’s why the P&L should always be reviewed alongside the balance sheet. See: Why Attorneys Need to Look at Their Balance Sheet.

Frequently Asked Questions
What is a good profit margin for a law firm?
It depends on practice area, firm size, and how owners are paid, so there isn’t one right number. The trend matters more than any single figure. A margin that holds steady or improves over time is a good sign, and a shrinking one is worth investigating.
Why doesn’t my P&L match my bank balance?
The P&L measures profit over a period, and your bank balance reflects cash on a given day. Owner draws, loan payments, client cost advances and the timing of collections all create differences between the two.
Should retainers show up as revenue?
Not until they’re earned. An unearned retainer belongs to the client and should be held as a liability. It becomes revenue when you bill for the work and transfer the earned amount.
Can I see profit by practice area or attorney?
Yes, if your books are set up for it. Using classes in QuickBooks, or connecting your practice management software correctly, lets you break down revenue and expenses by practice area or attorney.
How often should I review my firm’s P&L?
Monthly. A monthly review lets you spot trends and fix problems during the year, instead of discovering them at tax time.
