There’s No Such Thing as a Non-Billable Employee
By Darren Wurz
Walk into almost any law firm and you'll hear the same vocabulary. Partners and associates are "billable." Intake staff, the office manager, the bookkeeper — they're "non-billable."
It's a category that feels harmless. It isn't.
That single word — non-billable — is one of the most expensive labels in your firm. You think it tells you which employees are pulling weight and which ones are just overhead. And it's almost always wrong.
The reframe
Greg Crabtree, in Simple Numbers, Straight Talk, Big Profits!, makes a point that should change how every law firm owner thinks about staffing:
There is no such thing as a non-billable employee.
Every person on your payroll contributes directly to profit. And a “non-billable” employee either makes your billable people more billable — or they don't earn their seat. That's it.
A great administrative assistant isn't "non-billable." She's the reason your associate can move three more matters this month instead of getting buried in low value tasks. A great intake coordinator isn't overhead — he's the difference between a 40% conversion rate and a 70% conversion rate. A sharp bookkeeper isn't a cost center — she's the reason you don't lose a weekend a month reconciling QuickBooks instead of practicing law.
Their output doesn't show up on a billing statement. But it absolutely shows up on your P&L.
The number that proves it
Crabtree calls gross profit per labor dollar the second most important KPI in any business — second only to net profit itself. The rule of thumb is simple. Add up everything you spend on labor in a given period (salaries, payroll taxes, benefits, the works). Then divide your gross profit by that number.
What is gross profit? Gross profit is your total revenue minus direct costs like “cost of goods sold.” Law firms don’t really have cost of goods sold to worry about, but you might have direct costs directly related to client work - think things like contract labor, direct case costs, etc. For simplicity, just use your “gross revenue” number.
If the result is above 2.0, your team is producing more than two dollars of gross profit for every dollar you spend on them. You're in healthy territory.
If it's below 2.0, something is structurally off. It might be the wrong people. It might be the right people in the wrong roles. It might be too many people for your current revenue. It might be a pricing problem or utilization problem. It might be a productivity or efficiency problem. But the ratio doesn't lie, and it doesn't care which seats are "billable" and which aren't.
And even though attorneys are “billable,” they still rely on you. Even though they can “bill hours” and therefore “pay for themselves,” they still require support, marketing dollars, software spend, etc.
What this changes about hiring
Once you stop thinking in billable vs. non-billable categories, two questions get a lot clearer.
The first is when to hire. Crabtree's rule: don't add headcount until your firm is consistently producing at least $2 in gross profit per labor dollar. If you’re under that threshold, you should focus on profitability in your current business before adding headcount.
The second is who to hire. When you stop sorting candidates into billable and non-billable buckets, you start asking a more useful question: will this person make the rest of my team more productive? Sometimes the highest-leverage hire is a paralegal. Sometimes it's an associate. Sometimes it's an ops manager who frees up forty hours of partner time a month. The label doesn't matter. The leverage does.
What this changes about your existing team
The harder conversation is about the people already on your payroll.
If you've got a "non-billable" employee whose work doesn't visibly lift the productivity of your billable people, that's a problem. Either the role isn't designed to create leverage, or the person in the role isn't the right fit for it. Both are fixable. Neither gets fixed by leaving the label alone.
And the inverse is true too. If you've got an administrative person who quietly makes everyone else faster, sharper, and more focused — they're not overhead. They're one of the highest-leverage employees in the firm. Pay them like it. Promote them like it. Don't let the org chart fool you about where your profit actually comes from.
The discipline behind it
Tracking gross profit per labor dollar isn't a one-time exercise. It's a rhythm. Crabtree recommends watching it weekly, not monthly. That's because labor is the largest expense in almost every law firm — and the only one you can actually adjust quickly when something changes.
Most firm owners don't run this number at all. The ones who do tend to make better hiring decisions, faster firing decisions, and structurally more profitable firms.
It's also one of the disciplines we’re teaching at our next Lawyer Millionaire Masterclass — alongside the five other core ratios that turn running a firm from gut feel into something closer to engineering. The next one is May 28, and we'd love to have you there.
