How contractors should track campaign spend by month

Here is the before picture for most contractors: the Google Ads account lives with a marketing agency, QuickBooks shows a line item called "advertising" that lumps every channel together, and ServiceTitan has lead-source data that no one has reconciled against the ad spend in weeks. At the end of the month, the owner asks how marketing is performing. The answer is a rough number, no attribution, and a shrug.

The after picture: every channel's spend is logged against the revenue it produced for that calendar month. You can see that Google Local Services Ads drove 34 booked calls at a cost per booked job well within your target, while the branded search campaign consumed 4,200 dollars and produced 8 jobs. You cut the branded search budget and shift it. That decision takes two minutes instead of two days of spreadsheet work.

Getting from the before to the after requires two things: a consistent way to record spend by channel by month, and a way to match that spend to booked revenue. The matching (attribution) is covered in depth in how to connect ad spend to booked revenue. This article focuses on the tracking cadence: what to log, when to log it, and which month-over-month signals tell you something is wrong.

The five data points to record per channel per month

A useful campaign spend record for a home-service company captures more than just spend. For each active channel, record these five fields at the close of every calendar month:

1. Spend. The actual dollars charged for the month, not the budget. Agency management fees should be logged separately.

2. Calls (or leads) generated. Pulled from your call tracking platform, your CRM lead-source report, or the ad platform itself. Pick one source and stick with it.

3. Booked jobs. How many of those calls turned into a scheduled job. This is the number that connects marketing to operations and is why the CSR booking rate matters to your marketing leader as much as to your call center manager.

4. Booked revenue. The total invoice value of those jobs. For HVAC or plumbing, this closes the loop between a Google Ads click and a completed repair or install.

5. ROAS (return on ad spend). Booked revenue divided by spend for the month. This is the number you compare month over month and channel over channel. It removes the size-of-budget effect so a 2,000-dollar local channel and a 12,000-dollar Google campaign sit on the same scale.

What the table tells you that a blended average hides

In the example above, the blended ROAS is 3.3x. That single number looks acceptable. But behind it, Google LSA is running at 5.9x and branded search is at 1.3x. Branded search alone consumed nearly a quarter of the marketing budget and produced revenue at barely above breakeven for most trade margins.

A contractor looking only at blended spend has no reason to act. A contractor looking at channel-level ROAS by month can cut branded search, shift 3,000 dollars into LSA, and recapture that margin without increasing total spend. That is the argument for tracking by channel and by month, not by quarter or by blended total.

Month-over-month signals that warrant a closer look

Once you have two or three months of data in the table, the following changes usually mean something shifted and need investigation, not just a note:

Spend up, calls flat or down. The most common sign that your cost per click has risen, often because a competitor entered the auction or your Quality Score dropped. Worth checking the channel before increasing budget further.

Calls up, booked jobs flat. This is a CSR issue, not a marketing issue. Routing, availability, or call handling changed. Check the booking rate for the same period before assuming the channel is at fault.

Booked jobs up, booked revenue flat. Average ticket dropped, possibly from job-mix changes, more diagnostic-only calls, or a promotion running that attracted lower-value work. Investigate at the job level before renewing the campaign.

ROAS down for two consecutive months on a previously strong channel. A single bad month can be seasonality, a slow week, or a data lag. Two months signals a structural change: competition, market saturation, creative fatigue, or a change in your service area.

A practical tracking cadence: weekly, monthly, and quarterly

Weekly: check spend pacing. Are you on track to hit the monthly budget or running ahead? A campaign that exhausts budget in the first three weeks of the month goes dark when call volume is still high. Pacing checks take five minutes and prevent a surprise drop in calls during the fourth week.

Monthly: complete the channel-by-month table above within the first three business days of the following month. Pull CRM lead-source data, reconcile call counts against call tracking, compute ROAS per channel, and flag any channel that moved more than 20 percent from the prior month without a clear explanation (seasonality, promotion, or a competitor change).

Quarterly: compare channel mix. Over three months, where has the ROAS improved? Which channels have a consistent trend downward? Use the quarter view to make budget reallocation decisions, not the monthly view, which is too noisy for structural changes.

What tools you need to make this work

Call tracking: a platform like CallRail assigns a unique phone number to each campaign source. Calls roll up against the campaign, so you know a specific call came from Google LSA rather than from organic search or a yard sign.

CRM lead-source data: for teams using ServiceTitan or similar platforms, every job carries a lead source. That tag is how you count booked jobs and booked revenue by channel. Keeping lead-source tags clean is the unglamorous prerequisite for everything else in this article.

Accounting: QuickBooks is the source of record for actual spend, broken by vendor (ad platform or agency). If your chart of accounts lumps channels, work with your bookkeeper to add sub-accounts or class codes by channel so the reports separate Google from Yelp from direct mail.

A connected marketing dashboard: when your call tracking, CRM, ad platforms, and QuickBooks are configured to feed a single live view, the monthly table above populates automatically. Operators using datacube can see spend, call volume, booked jobs, and ROAS by channel updated throughout the month rather than assembled at close.

Three campaign spend tracking mistakes that cost contractors margin

Mistake 1: counting impressions and clicks as conversions. Ad platforms are optimized to show you the metrics that make them look good. Impressions and clicks cost money but do not pay your techs. Unless the platform conversion tag fires on an actual call or a form fill tied to a booked job, the conversion number is a proxy at best.

Mistake 2: attributing all revenue to the last click. A homeowner may have clicked a Google Search ad, visited your website, then searched your brand name and called from a Yelp listing two days later. Last-click attribution gives Yelp full credit and Google none. For most home-service companies, a simple first-touch or even a 50/50 split model is more honest than last-click for high-ticket, multi-day decisions.

Mistake 3: reviewing spend after the month is gone. If you do not look at campaign spend until day five of the following month, there is nothing you can do about the 4,200 dollars your branded campaign wasted. Build a weekly pacing check into your rhythm so you have time to act within the month.
