A health check measures the metrics that predict whether your agency thrives or stalls in the next twelve months. The ones top-line revenue can hide for years.
Most agencies confuse a health check with a P&L review. They look at last quarter's revenue, last quarter's expenses, last quarter's net income, declare themselves "doing well" or "tight," and move on. That's accounting. Accounting is the rear-view mirror, useful for what already happened and useless for what's coming next.
A health check measures the metrics that predict the next twelve months. It looks at revenue per employee, client concentration, pipeline coverage, gross margin, utilization, and twelve-month retention. None of those show up on a P&L. All of them tell you whether the business will be alive and growing in a year, regardless of how last quarter looked.
The reason this matters is simple. Top-line revenue can hide a lot. An agency hitting $4M in revenue can be one client churn away from layoffs, or two senior departures away from a quality crisis, or six months away from realizing their margin has shrunk to 8%. The P&L will keep saying "things are fine" right up until they aren't.
Most owners watch revenue. Maybe gross profit on a good month. The numbers below tell you something revenue can't: whether the underlying business is getting healthier or weaker, regardless of what the top line says.
1. Revenue per employee (RPE). The most underrated agency metric. Take total revenue, divide by full-time headcount including the founder. Healthy RPE for service agencies sits in the $150K-$250K range depending on the niche. Below $120K, you're either underpriced or overstaffed. Above $300K, you're either burning out the team or under-investing in the people you have.
2. Client concentration. What percentage of revenue comes from your top three clients? Anything above 35% from a single client is a danger zone. One client at 25% means a single churn event triggers layoffs. Healthy is below 25% from any single client and below 50% from your top three combined.
3. Pipeline coverage ratio. Total open pipeline divided by your revenue target for the next 90 days. Healthy is 3-4x. Below 2x means you're going to miss your number. Above 6x means your pipeline is full of garbage you haven't qualified out yet. Both are problems. Both go undetected if you only watch closed-won.
4. Gross margin. Revenue minus the cost of delivery (people on the work, contractors, direct project costs). Healthy agency gross margin sits between 50% and 65%. Below 50% means scope creep, undisclosed discounts, or pricing you set when you were smaller. Above 70% usually means you're under-delivering or charging premium prices the work doesn't actually justify.
5. Utilization rate. Billable hours divided by total available hours for client-facing roles. The classic agency trap is targeting 80%+ utilization, then wondering why senior people quit. Healthy is 65-75% for senior roles, 75-85% for mid-level. Above 85% sustained is burnout territory, and the people doing the best work leave first.
6. Twelve-month employee retention. Of the people who were on the team a year ago, how many are still here? Below 75% retention means something is structurally wrong with how the agency operates, almost regardless of what people say in exit interviews. Above 90% can also be a flag if it correlates with low growth (people staying because they've stopped trying).
Each of these can be measured in less than 30 minutes if you have your basic data. Most agencies have never run all six together. The combination is what tells the story.
Revenue is the loudest metric in the agency, which is why it's the one owners watch first. The problem is that revenue trails the actual health of the business by anywhere from 6 to 18 months. By the time revenue tells you something is wrong, the underlying problems have been getting worse for over a year.
Here's how that plays out. Your gross margin shrinks from 58% to 51% over twelve months because you've been quietly underpricing new work to win it. Revenue keeps growing because volume offsets the margin drop. Then in month thirteen, two anchor clients renew at flat rates while costs keep going up, and suddenly you're underwater. The revenue line still looks fine. The actual business is in serious trouble.
Or this one. One client grows to 38% of revenue over two years because you kept saying yes to every project they brought you. The relationship is great. The work is good. Revenue is up. Then their CMO leaves, the new one wants to consolidate vendors, and you lose the account in a single month. You've now lost almost 40% of your revenue with three weeks of notice. Anyone watching client concentration would have seen this coming twelve months ago.
The metrics that matter are the ones that catch problems while you can still fix them. Revenue catches problems after they've already happened. That's the difference.
Most agencies don't track these numbers because nobody has explicitly told them which ones to track. The cost of that gap is real and measurable. Here's what each metric protects you from when you watch it, and what it costs when you don't.
Revenue per employee. Not watching it means you don't notice when you're overstaffed for your revenue. Three or four extra full-time roles you should never have hired show up as $300K-$500K in unnecessary annual payroll. Most agencies discover this only when they have to do a layoff to fix it.
Client concentration. Not watching it means a single client churn event becomes a layoff event. The cost is the wage bill of the people you have to let go, plus the institutional knowledge that walks out with them, plus 18 months of recovery to rebuild what you lost.
Pipeline coverage. Not watching it means you find out you're going to miss the quarter when the quarter is already half over. The cost is the panic-driven pricing concessions and the stretch deals you take to make the number, both of which weaken margin and brand.
Gross margin. Not watching it means scope creep slowly eats your profitability without anyone noticing. The cost is paying yourself a smaller and smaller share of what you bring in until you wake up taking home less than your senior employees.
Utilization rate. Not watching it means you push the team too hard for too long, the senior people leave, and you're left replacing them at higher salaries with less skilled hires. The cost is recruiting fees, ramp time, and the work that ships worse for two quarters while the new people learn.
Employee retention. Not watching it means you don't notice that the people doing the best work are quietly job-hunting. The cost is when they leave in a cluster, taking client relationships with them. Some of those clients leave with them.
Six numbers. Thirty minutes a quarter. Most owners spend that much time on a single Slack thread.
You can run a health check without software. The work takes ten minutes with your books and twenty minutes with your team. Here's the process most agencies can do in a single sitting.
Pull the six numbers. Revenue per employee, client concentration, pipeline coverage, gross margin, utilization, twelve-month retention. Calculate them honestly. Don't round up. Accuracy beats a flattering picture every quarter of the year.
Compare to the healthy ranges. $150K-$250K RPE. Top-three concentration below 50%. Pipeline coverage 3-4x. Gross margin 50-65%. Utilization 65-75% for seniors, 75-85% mid-level. Retention above 75%.
Find the one that's farthest from healthy. That's your priority. Most owners try to fix everything that looks off. That's how you make slow progress on five problems instead of fast progress on the one that matters.
Set a 90-day target for that single metric. Don't try to move the others. Move the one that's most exposed. Re-measure in 90 days. The metric that was farthest from healthy last quarter probably isn't the one that's most exposed this quarter, because once you've moved it, something else becomes the constraint.
This is the rhythm that separates agencies that grow from agencies that drift. Most agencies measure once a year and lose 11 months of warning signs. Quarterly is enough to catch problems while they're still cheap to fix.
If you want the version that does the calculation and benchmarking for you, the WTF Assessment scores your agency on these dimensions and shows you which one to move first. Five minutes. The metrics work the same whether you measure them yourself or have us measure them.
The six that matter most are revenue per employee, client concentration, pipeline coverage ratio, gross margin, utilization rate, and twelve-month employee retention. Together they predict whether the agency grows, holds steady, or declines over the next twelve months. Other metrics (NPS, project delivery on time, etc.) are useful but secondary.
For service agencies, healthy revenue per employee sits between $150K and $250K depending on the niche and seniority mix. Below $120K usually means underpricing or overstaffing. Above $300K usually means burnout risk or under-investment in the team. Niche specialists run higher than generalists, and agencies with offshore delivery teams skew differently from US-only operations.
Anything above 35% revenue from a single client is a danger zone. Above 50% from your top three combined is also a flag. The reason concentration matters is that one churn event at high concentration triggers layoffs and recovery that can take 12 to 18 months. Healthy concentration is below 25% from any single client.
Quarterly is the right cadence. Annually is too slow to catch problems while they're still cheap to fix. Monthly is too noisy and most metrics don't move enough month-to-month to be meaningful. Quarterly matches the rhythm of how agency systems actually move and gives you four chances per year to course-correct.
Healthy agency gross margin sits between 50% and 65% (revenue minus the cost of delivery, including direct labor and contractors). Below 50% usually signals undisclosed discounts, scope creep, or outdated pricing. Above 70% can mean under-delivery or unsustainable premium pricing. The right number for your agency depends on your service mix and delivery model.
A financial audit verifies the accuracy of past financial statements. A health check measures forward-looking operational metrics that predict whether the business will thrive in the next twelve months. An audit tells you what the books say happened. A health check tells you what's about to happen and gives you time to react.
The WTF Assessment runs the metrics that predict your next twelve months and shows you the one that needs attention first. Five minutes, no spreadsheet required.
