Per inspection vs agency retainer is a question about who carries the risk in a bad month. A retainer bills the same in a month where your estimator saw thirty houses and in a month where he saw four. Per inspection billing only moves when a dated slot lands on your calendar and the homeowner is standing in the doorway when you get there. The invoice follows the work instead of the calendar month.
That's the whole structural difference, and it decides a lot. It decides who is nervous in February. It decides what a vendor argues with you about. And it decides whether the person running your ads loses anything when they stop working.
The short version
- A retainer is a fixed monthly cost. Per inspection is a variable cost that tracks output.
- On a retainer, a slow month costs you the fee plus the empty days. On per inspection it costs you the empty days only.
- Scorpion states on its own FAQ that it typically requires a 12-month contract for marketing technology and services such as SEO.
- The Foundation Fix Pipeline has no retainer and no cost per lead, call or form fill. You pay per booked qualified inspection that happens.
- Retainers buy you a team and a plan. Per unit buys you output and nothing else, which is a real limitation.
What happens in a dead February
Picture the month where it rained for three weeks and nobody wanted anybody in the crawl space. On a retainer your invoice is identical to January's. You pay for strategy, reporting, a call with an account manager, and a dashboard showing that impressions were up. None of it put a truck in a driveway, and none of it stops.
On per inspection billing that month is quiet on both sides. Fewer slots filled, so a smaller bill. The vendor feels the slow month at roughly the same moment you do, which changes what gets worked on, because nobody has to be persuaded that the number matters.
This is not an argument that retainers are dishonest. It is an argument that fixed fees and variable output point in different directions, and you should know which direction your vendor is pointing when the season turns.
Read the term before you read the price
The contract length tells you more than the monthly number does. Scorpion, one of the larger agencies serving home services, answers it directly on its own FAQ: it typically requires a 12-month contract for its marketing technology and certain marketing services like search engine optimization, while digital advertising services are typically month to month. That is a clear answer and I respect them for publishing it. It also means that on part of the relationship you are committed for a year before you have seen a result.
Then read the ownership clause. Scorpion's FAQ says you own your website after the length of your contract is complete, that you'll not own the underlying system, and that if you leave you'll need to work with another vendor to rebuild your website on a content management system of your choosing. There's nothing hidden about that, but it's the kind of thing worth knowing in month one rather than month thirteen.
Per inspection billing has its own fine print and you should hold it to the same standard. Ask what counts as a booking, what happens on a no-show, and when the bill arrives.
Which shape costs you less?
| Monthly agency retainer | Per booked inspection | |
|---|---|---|
| Invoice in a dead month | The same as a good month | Smaller, because fewer slots filled |
| Who feels a bad week first | You | Both of you |
| Typical commitment | Often 12 months on parts of the service | Month to month |
| What you're buying | Hours, a plan and a team | Output you can count |
| What's easy to measure | Activity and output of work | Inspections attended |
| What's hard to measure | Whether any of it made the phone ring | Anything beyond booked inspections |
| Brand work, site, content | Usually included | Not included at all |
| Who owns the ad account | Varies, so ask before you sign | You, on your own card |
| Risk if the market softens | Yours alone | Shared, by construction |
Which shape fits the shop you actually run
- You're under roughly $2M a year and every month has to pay for itself
- Go per unit. A fixed fee in a soft quarter is the thing that kills small shops, and you can't ride it out the way a bigger company can.
- You need a website, local search, review management and ads under one roof
- Pay a retainer, because no per-unit vendor does any of that and stitching five vendors together costs you more than the fee.
- Your estimator's calendar is the only number you care about this year
- Go per unit, and ignore every report that measures anything else.
- You already have a marketing person in-house who can direct the work
- A retainer agency is often the cheaper way to buy hands, because you are supplying the direction yourself.
When Retainer agencies is the better buy
- You want one vendor accountable for the website, local search, reviews and ads instead of four relationships to manage.
- You are building a brand in a market for the next five years, and brand work does not fit a per-unit invoice.
- You have an in-house marketer who can steer an agency, which turns a retainer into cheap senior capacity.
- You run several locations and need reporting that rolls up, which per-unit vendors are generally not built to produce.
- You want the strategy conversation, the quarterly plan and somebody to argue with about positioning. None of that is in a per-unit deal.
- Your revenue is steady enough through the year that a fixed fee is simply a line item and not a risk.
Is per inspection just a retainer with extra steps?
Only if the vendor sets a minimum. Ask whether there is a monthly floor, a minimum unit commitment or a setup that renews. If any of those exist, you have a retainer wearing a different name. The Foundation Fix Pipeline has no retainer and no minimum volume.
Do I still pay for the ads on a per-unit deal?
Yes. The media spend is yours, on your own card, in your own ad account. A vendor fee and a media budget are two separate things, and any vendor who blurs them is making their own cost harder to see.
What stops a per-unit vendor from sending junk to run the count up?
The refund rule. A no-show or an unqualified booking is refunded, no questions asked, when you report it within 72 hours of the appointment. If the vendor has no such rule, the count is the only thing being optimised.
How long before a per-unit arrangement is worth judging?
Give it 90 days. That is also where the guarantee starts counting, for the same reason: campaigns need time to settle and a first month tells you almost nothing either way.
If you want a bill that only moves when your calendar does, book a 30-minute call.
