Customer Acquisition Cost for Home Services Businesses
Customer acquisition cost is the total cost of winning new customers, divided by the number of new customers won over the same period. A true figure is fully loaded: it includes advertising, agency fees, tracking, creative and page production, and the business’s own sales costs. At Riley Summers, our work is built around winning customers at a cost the business can afford. We report the marketing side of the figure, and the rest sits in the owner’s books unless they choose to share it.
Most marketing figures only count the first layer. Customer acquisition cost counts them all.
Marketing generates the opportunities, but the cost of winning a customer extends beyond marketing. Understanding what a new customer really costs means counting every expense involved in turning a caller into a customer.

How Customer Acquisition Cost Is Calculated
Customer acquisition cost = total acquisition costs ÷ new customers won, for the same period.
The division is simple. The work is in deciding what goes on each side of it.
The costs. A true customer acquisition cost is fully loaded. It counts every expense involved in winning a new customer:
- Media spend on every channel.
- Agency fees.
- Tracking and tools, such as call tracking and analytics.
- Creative and page production.
- The business’s own sales and marketing costs: estimator or comfort advisor time, sales commissions, the office and intake staff who book new customers, and any in-house marketing staff.
That last group is the one most often left out, and it’s often one of the largest. In Mark Riley’s experience in legal marketing, firms usually counted their intake and case-management time when they talked about what a case cost them.
Shared costs. Some costs serve more than new customers. An office manager who answers the phone books repeat customers as well as new ones, and an agency fee may cover several channels. For customer acquisition cost, only the share that goes to winning new customers belongs in the figure. For a channel-by-channel view, shared costs are spread across the channels they support.
The customers. Only new customers count: people buying from the business for the first time. Repeat work from existing customers is left out, because it wasn’t acquired in that period. That means the figure depends on the business knowing which jobs came from new customers.
The period. Costs and customers must cover the same period. For work that takes weeks or months to close, that takes care, as the section on why customer acquisition cost arrives late explains.
Of these costs, we report the marketing layers precisely: media spend and our fees. We set up tracking tools in the client’s own name, on their own card, so they see those costs directly and keep full access to the accounts. The business’s own sales costs sit in the owner’s books unless they choose to share them, which is why a complete customer acquisition cost is a business-level figure rather than a marketing report.
What Customer Acquisition Cost Is and Isn’t
Customer acquisition cost answers the question behind every growth decision: what does it cost the business, all in, to win one new customer? It’s the figure that shows whether growing the customer base is paying for itself.
It’s easy to confuse with the marketing figures around it. The difference is in which costs each one includes and what it counts:
| Measure | Costs it includes | What it counts |
|---|---|---|
| Cost per lead | A channel’s direct cost | Every call and contact form |
| Cost per booked job | A channel’s direct cost | Every booked job, new customer or repeat |
| Customer acquisition cost | Every acquisition cost, marketing and sales | New customers only |
| Marketing return on investment | Marketing costs, set against what they earned | The return, not the cost |
Customer acquisition cost also isn’t a measure of what a customer is worth. A $600 customer acquisition cost is expensive for a one-time $400 repair and inexpensive for a customer who stays on a maintenance plan for years. That’s why it only means something next to the customer’s value, which is covered in the acquisition view of revenue attribution, with the wider economics on Gross Margin & Marketing.
Three Layers of Acquisition Cost
Every dollar spent winning a new customer falls into one of three layers. Separating them matters, because when customer acquisition cost rises, the layers show where the increase came from.
Layer one: marketing costs
Media spend, agency fees, and tracking and tools. This is the layer that moves with the budget and the market: rising competition, a change in targeting or a seasonal push all show up here first. It’s also the layer we report precisely, every month, by channel.
Layer two: production costs
The creative and page production behind the campaigns: ad images, video, copy and the pages ads send people to. These costs tend to arrive in bursts rather than monthly, so they belong spread across the months the work is in use. Otherwise, the month a new campaign launches looks expensive, and every month after it looks cheaper than it really is.
Layer three: the business’s sales costs
Estimator and comfort advisor time, sales commissions, and the office and intake staff who turn calls into booked customers. This layer sits in the owner’s books, and for replacement and high-ticket work it can be the largest of the three. It’s also where the second lever from cost per booked job shows up in money: every lead lost on the phone raises the sales cost of each customer the business does win.
A rise in customer acquisition cost means something different depending on the layer. If it’s the marketing layer, the campaigns or the market have changed. If it’s production, the business may be refreshing its creative, which should settle. If it’s the sales layer, it may be taking more estimates or more staff time to close each new customer. Each calls for a different response, and only one of them is a marketing problem.
How Riley Summers helps: When the full figure rises, the marketing usually gets the blame first. We report the marketing layer clearly and separately every month, so the owner can set their own sales costs beside it and see which layer actually moved.
Why Customer Acquisition Cost Arrives Late
Customer acquisition cost is the most complete measure of what growth costs, and also the slowest. It can’t be known until the customers are actually won, and for some work that takes a long time.
Mark Riley saw the extreme version of this in legal marketing. Many cases took over a year to resolve, so the true cost of acquiring a client wasn’t known until long after the campaigns that produced them had moved on. By the time the figure was settled, the budgets, targeting and even the channels behind it had changed.
Home services has a shorter version of the same problem. A repair customer is usually won within days. But a replacement or high-ticket job can close weeks or months after the first call, and some estimates never close at all. Until those sales are settled, customer acquisition cost for the period is still moving.
In the meantime, businesses don’t have to fly blind. The firms Mark Riley worked with used directional figures based on similar past cases, and on how insurance companies had handled them, to estimate what a new case would likely come to long before it settled. A home services business can do the same with its own history. If the business knows roughly how many of its estimates usually close and how long they take, it can estimate this period’s customer acquisition cost well before every sale is settled, then correct the figure as the real results come in. The estimate is only as good as the history behind it, but it’s far better than waiting a year to find out.
That’s why we don’t manage campaigns on customer acquisition cost. Campaigns need figures that arrive quickly enough to act on: cost per lead within days, and cost per booked job within weeks. Customer acquisition cost is the longer view. It’s best evaluated over a quarter or more, where it shows whether the business’s growth is paying off as a whole.
| Figure | When it’s available | What it’s used for |
|---|---|---|
| Cost per lead | Within days | Steering campaigns week to week |
| Cost per booked job | Within weeks, where the client shares booked jobs | Evaluating channels and campaigns |
| Customer acquisition cost | Months later, for long-cycle work | Evaluating whether growth is paying off |
How Riley Summers helps: Waiting for the full figure before acting means reacting to campaigns that no longer exist. We manage campaigns on the figures that arrive first, and report them in a way the owner can set against their full acquisition cost as it settles.
New Customers vs. Existing Customers
Customer acquisition cost counts new customers only: people buying from the business for the first time. Repeat work matters enormously to a home services business, but it isn’t acquisition. That customer was already won, and their cost was counted when they were.
Mixing the two makes acquisition look far cheaper than it is.
Illustrative figures only, not a benchmark.
In one month, a business books 100 jobs. Sixty come from new customers and 40 from existing ones. Its fully loaded acquisition costs for the month are $12,000.
- Counting new customers only: $12,000 ÷ 60 = $200 per new customer.
- Counting every job: $12,000 ÷ 100 = $120, which looks 40% cheaper but isn’t an acquisition cost at all.
The second figure flatters the marketing, and it can lead an owner to believe they can afford to spend more on growth than they really can.
The same principle applies to costs. Marketing aimed at existing customers, such as remarketing to past customers or promoting a maintenance plan to people already on the books, is retention spending. It keeps customers, rather than winning new ones, so it stays out of customer acquisition cost.
Referrals raise a similar question. A customer referred by a neighbor or a past customer is new to the business, but no marketing campaign won them. In Mark Riley’s experience in legal marketing, referred cases were never credited to the agency. That’s the right principle for a home services business too. A business-wide customer acquisition cost counts every new customer, referrals included, and the referrals pull the average down because they cost little to win. The cost of customers won through marketing is a separate, higher figure. Reporting the two separately stops referrals from making the marketing look cheaper than it is, or from hiding what the business’s reputation is worth.
Two judgment calls come up often. A customer returning after several years without any contact may be treated as newly won. A household that moves and becomes a new customer at a new address may be too. Either choice can be defensible. What matters is that the business makes it once and applies it consistently, so the figure is comparable from one period to the next.
This is also why customer acquisition cost only means something next to what a customer is worth over time. The value of a customer’s repeat work is covered in the acquisition view of revenue attribution.
Customer Acquisition Cost by Channel
A business-wide customer acquisition cost shows whether growth is paying off overall. A channel-by-channel view shows where it’s paying off. Getting there means sharing out the costs that no single channel owns. Businesses that calculate it by channel usually share them out like this:
| Cost | How it’s usually shared across channels |
|---|---|
| Media spend | Belongs to the channel it was spent on |
| Agency fees | Spread by the share of spend or work each channel takes |
| Tracking and tools | Spread across the channels they serve |
| Creative and page production | Belongs to the channels that use it, spread over the months it’s in use |
| The business’s sales costs | Spread by the share of new customers each channel produces |
The method matters less than applying it the same way every period, so each channel’s figure can be compared over time.
We approach channel costs from the other direction. Rather than splitting our fee across channels after the fact, we build our recommendations channel by channel and total them into one plan. If the business doesn’t have the budget for all of it, or doesn’t want to spend that much, we trim the supporting channels first and leave the core channels, the ones producing most of the work, untouched for as long as possible. That way, a smaller budget costs the business the least possible in new customers.
SEO changes over time. SEO is paid for months before it produces most of its customers, so its customer acquisition cost starts high and falls as visibility builds. Evaluated in its first months, it can look like the most expensive channel a business runs. Evaluated over a year or more, it’s often one of the least expensive.
Branded search. Branded search is where this matters most. In Mark Riley’s experience in personal injury law, winning cases was largely a branding game, and searches that didn’t include a firm’s name were the smaller part of the picture. Home services has a version of the same pattern. An established business gets calls from people who already know its name, from its trucks, yard signs, reputation and past work. Those customers often arrive through a search for the business’s name, which makes branded search look like the cheapest channel of all. But the cost of winning them was paid earlier, by everything that made the name familiar. A true customer acquisition cost includes that brand spend, even when no single channel gets credit for it. That’s why we report branded and non-branded search separately.
A channel-by-channel customer acquisition cost also depends on the business telling us which of its new customers came from which channel. Where they do, we can set each channel’s media spend against the new customers it produced. The owner adds the fees, production and sales costs to complete the picture.

What We Contribute to Customer Acquisition Cost
Customer acquisition cost is a business-level figure. An agency can see all of it when the business shares its costs, but not every business wants to, and that’s their call. What we always do is report the marketing side precisely, every month, in a form the owner can set beside their own costs.
| What it includes | Who has it | |
|---|---|---|
| What we report | Media spend by channel and our fees, alongside the tracking tools we set up in the client’s own name and billed to their own card | Riley Summers, every month, and the client directly, since the tools are their accounts |
| What the owner adds | Production costs they pay directly, and their own sales costs: estimator time, commissions, and office and intake staff | The owner’s books, shared with us where they choose |
| What completes the figure | Which jobs came from new customers, and from which channel | The owner’s records, shared with us where they choose |
Worked example
Illustrative figures only, not a benchmark.
In one quarter, a business wins 40 new customers through its marketing.
Marketing costs: $7,500 in media, $2,000 in fees, and $500 in tools billed directly to the business, for $10,000 in total. $10,000 ÷ 40 = $250 per new customer.
Costs the owner adds: $600 in production and $4,400 in sales costs. Fully loaded, $15,000 ÷ 40 = $375 per new customer.
On marketing costs alone, each new customer looks like it costs $250. The true figure is $375, half as much again. Neither number is wrong. But only the second one tells the owner what growth is really costing the business.
Customer Acquisition Cost Mistakes We See
These are the mistakes we most often find when a business looks at what it costs to win a new customer. Several of the fixes depend on the business sharing its own figures, so we apply them wherever it chooses to.
| Mistake | Why it costs the business | What we do instead |
|---|---|---|
| Leaving sales costs out | The figure can look a third lower than it really is, so growth seems more affordable than it is | We report the marketing layer separately and clearly, so the owner can add their sales costs beside it |
| Counting repeat work as acquisition | Existing customers make acquisition look far cheaper, and the business overestimates what it can spend on growth | Where the client shares which jobs came from new customers, we count only those |
| Letting referrals flatter the marketing | Low-cost referrals pull the average down and hide what marketing-won customers really cost | Where the client shares each customer’s source, we report referrals separately from customers won through marketing |
| Crediting branded search with customers the brand created | Branded search looks like the cheapest channel, and brand-building gets cut because it can’t show direct results | We report branded and non-branded search separately, so the owner can see which customers the name is bringing in |
| Managing campaigns on a figure that arrives months later | Decisions are made about campaigns that have already changed | We manage campaigns on cost per lead and cost per booked job, and evaluate customer acquisition cost over a quarter or more |
| Charging production costs to a single month | The launch month looks expensive and every month after looks cheaper than it is | We flag production costs when they land, so they can be spread across the months the work is in use |
| Evaluating SEO in its first months | SEO looks like the most expensive channel before its customers arrive, and gets cut too early | We evaluate SEO’s cost per new customer over a year or more |
| Cutting core channels first when the budget tightens | The channels producing most of the new customers lose budget, and acquisition cost rises | We trim supporting channels first and protect the core for as long as possible |
Customer Acquisition Cost Across Home Services Trades
| Trade | What changes in customer acquisition cost |
|---|---|
| HVAC | A replacement customer can carry heavy sales costs, such as comfort advisor visits and commissions, while a repair customer carries very little, so the figure varies widely by type of work |
| Plumbing | Many new customers are won on the first call with little sales time involved, so the marketing layer makes up most of the figure |
| Electrical | Even mid-sized jobs often go through a message, a site visit and a quote before they’re won, so sales time is part of the cost of many new customers, not only the large projects |
| Roofing | Inspections, estimates and long closing times make both the sales layer and the delay in knowing the true figure unusually large |
| Pest control | New customers often start ongoing plans, so the figure is set against years of service rather than the first visit |
| Pool service | A maintenance customer is won once and may stay for many seasons, while a repair customer may never return |
| Lawn care | Most new customers arrive in a short spring window, so a quarter’s figure swings sharply with the season |
Two patterns stand out. Where the sales process is heavy, as with HVAC replacement, roofing, much electrical work and other high-ticket jobs, the business’s own sales costs and the delay before the true figure is known drive customer acquisition cost. Even a mid-sized job, such as installing a 220V outlet and new wiring, can take a text exchange, a site visit and a written quote before any work is booked. Every one of those steps is sales time the business spends to win the customer. There, a marketing-only figure understates the real cost the most. Where customers are won quickly and kept, as with pest control, pool service and lawn care, the figure itself is simpler. The harder question is what those customers are worth over the years they stay.
