You’re running ads, asking customers for referrals, maybe posting on Facebook. Money is going out the door. But when someone asks, “Is your marketing working?” — you shrug and say, “I think so.”
That’s a problem.
A Keap survey found that 46% of small business owners aren’t sure whether their marketing is working — and 17% know it isn’t. If you’re in that group, it’s not because you’re bad at marketing. It’s because you’re not measuring it.
The good news: you don’t need a marketing department, a fancy CRM, or a dashboard full of charts. You need six numbers. Track those consistently, and you’ll know more about your marketing in 90 days than most business owners learn in years.
Here’s the core principle behind every good marketing decision: you can’t improve what you don’t measure.
If you double your ad spend and get more calls, was that the ads? The season? A great review someone left last month? Without baseline numbers, you’re guessing — and guessing gets expensive.
The goal here isn’t complexity. A simple spreadsheet updated once a week is enough to get started. No software subscription required. What matters is that you pick a starting point, write the numbers down, and look at them regularly.
That’s it. That’s the whole system at first.
What it is: The total number of new inquiries you receive each month — phone calls, texts, emails, and website contact form submissions.
Why it matters: Lead volume is your marketing heartbeat. If it’s going up, something is working. If it drops, something changed. Without this number, you have no way to know whether your marketing is generating interest or falling flat.
How to track it: Keep a simple tally. Every new inquiry gets logged — the date, how they reached out, and where they found you. A notes app, a whiteboard, or a spreadsheet all work fine. Phone calls are the primary lead channel for most home service businesses, so start there. If you also get website form submissions, count those too, but don’t let the digital tracking become a project that never gets started.
What it is: Where each lead came from — Google search, a referral, Facebook, a yard sign, a door hanger, etc.
Why it matters: This is arguably the most valuable metric on this list. Once you know which channels are sending you customers (not just leads, but customers), you can stop guessing where to spend your marketing dollars.
Most service businesses are surprised by what they find. The $500/month they’re spending on ads might be producing fewer customers than the referral program they set up but never thought much about.
How to track it: When a new lead calls or reaches out, ask one simple question: “How did you hear about us?” Log the answer. That’s it. Do this every time, without fail. After 60–90 days, the patterns will be obvious.
What it is: The percentage of your leads that actually become paying customers.
How to calculate it: Divide the number of new customers by the number of leads in the same period, then multiply by 100.
Example: 20 new customers ÷ 50 leads = 40% conversion rate
Why it matters: More leads isn’t always the answer. If you’re converting 20% of leads but your competitor converts 50%, the problem isn’t your marketing — it’s your follow-up, your pricing, your response time, or something in the sales conversation. Tracking this number separates a marketing problem from a sales problem.
How to track it: Once you’re logging lead volume, conversion rate is automatic. Just note which leads turned into jobs.
What it is: How much money you spend, on average, to win one new customer.
How to calculate it: Add up your total marketing spend for the month (ads, mailers, sponsorships, any paid marketing). Divide that by the number of new customers you brought in.
Example: $1,000 in marketing ÷ 10 new customers = $100 CAC
Why it matters: This number tells you whether your marketing is efficient or expensive. A $100 CAC means nothing on its own — but if your average job is worth $150, you have a problem. If your average job is worth $800, you’re in great shape. CAC only makes sense when you look at it alongside the next two metrics.
How to track it: Keep a running total of what you spend on marketing each month. Most service business owners already know this number — they just haven’t connected it to the customers it produces.
What it is: The average amount a customer pays you per job or service.
How to calculate it: Total revenue for the month ÷ number of jobs completed.
Example: $12,000 in revenue ÷ 20 jobs = $600 average job value
Why it matters: This metric directly shapes your strategy. If your average job value is low, you need either higher volume or a way to increase it (upsells, service packages, premium options). It also tells you how much you can afford to spend acquiring a customer. If your CAC is creeping toward your average job value, your margins are evaporating.
How to track it: Pull this from your invoicing software, or tally it manually from completed jobs at the end of each month.
What it is: The total revenue you can expect from a single customer over the entire time they work with you — not just the first job.
How to calculate it (simple version): Average job value × average number of times a customer hires you per year × average number of years they stay a customer.
Example: $600 average job × 2 jobs per year × 3 years = $3,600 CLV
Why it matters: This one changes how you think about marketing entirely. A customer who looks like a $600 sale is actually a $3,600 relationship. That means you can afford to spend more to acquire them than you might think — and it puts serious emphasis on the value of repeat business and referrals.
For home service businesses especially, CLV is often underestimated because owners think in terms of single jobs rather than long-term customer relationships.
How to track it: Start by estimating. Look back at your best repeat customers and calculate how much they’ve spent over the years. Even a rough CLV number is far more useful than no number at all.
You do not need to buy anything.
Open a Google Sheet or Excel spreadsheet. Create six columns:
That’s your entire tracking system to start. Every new inquiry gets a row. Every completed job gets updated. Once a month — set a recurring 30-minute calendar block — you tally the numbers and calculate your metrics.
It’s not glamorous. It works.
As your business grows, tools like Jobber, Housecall Pro, or even a basic CRM will automate most of this. But don’t wait for the perfect tool. Start with the spreadsheet. The habit of looking at the numbers matters more than the software you use to track them.
After your first 60–90 days of tracking, you’ll have something most of your competitors don’t: actual data about your own business.
Now put it to work. Ask yourself:
One rule: make one change at a time. If you adjust your ad spend, change your follow-up process, and update your pricing all in the same month, you won’t know which one moved the needle. Small, deliberate changes — measured against your baseline — is how you actually improve.
Most small service businesses make marketing decisions based on gut feeling and hope. That’s expensive.
Six metrics, tracked consistently in a simple spreadsheet, will give you a clearer picture of your marketing than most business owners ever have. You’ll know where your best customers come from, how much it costs to get them, and whether the money you’re spending is actually working.
Start this week. Pick up the habit before it feels urgent.
Most small service business owners are spending money on marketing without any idea if it’s working. The fix isn’t a bigger budget or fancier software — it’s six simple numbers. Here’s exactly what to track and how to start today.
Organic or paid advertising — why choose? Small businesses that use both grow faster and smarter. Learn how to balance the two and get results whether you need them now or later.
