Capacity is sold by the minute or lost for good
Chain speed and vehicle spacing fix how many cars an hour a tunnel can process, and no month-end report shows the cars that saw the queue and kept driving. So the first CFO exercise is capacity accounting: what the site can move at peak, what share of the biggest days it actually captures, and where the constraint really sits, at loading, at the pay stations or in the tunnel itself. Fixes then become investments with a denominator: a faster loader or a dedicated member lane is priced against the peak cars it recovers, not bought out of frustration.
The same math disciplines membership growth. Members buy access to exactly those peak mornings, so a base that outgrows peak throughput converts your best customers into your longest queue. Growth targets need to come from throughput, not from a subscriber number picked in a spreadsheet. The margin logic sharpens the point: a tunnel's marginal car costs little beyond chemicals and a few minutes of hydro, so every peak car recovered is close to pure margin, and the capacity fix list gets ranked by cars recovered per dollar spent.
Membership pricing is a churn decision
The bookkeeping side of memberships, the deferred-revenue schedule and the month-end churn report, is built in our car wash accounting work; the CFO side is deciding with those numbers. Every pricing move trades revenue per member against member movement, and the movement only shows up one or two billing cycles later, which is why pricing by gut feels free and never is.
| Pricing move | What it usually buys | What to watch |
|---|---|---|
| Raising the base plan | Revenue per member up immediately | Cancellations over the next two billing cycles |
| Adding a premium tier | More revenue from the keenest members | Whether upgrades are new money or drained from the base tier |
| First-month discounts | Sign-up volume | Churn at the first full-price renewal, and payback per member |
| Annual prepaid plans | Cash up front and a year without churn | A year of washes owed, and HST due on the whole charge at once |
| Fleet and commercial plans | Weekday volume in quiet hours | Discounts only where capacity would otherwise sit idle |
We run every move as a small model first: current churn split into cancellations and failed cards, revenue per member by tier, and the break-even member loss the change can absorb. Then the billing data proves it or kills it within a quarter.
Detailing answers to the labour hour
Detailing looks like the tunnel's natural upsell and behaves like a different company: hand labour, long jobs, skilled staff, no machine leverage. Blended statements let tunnel margin quietly subsidize detail packages priced below their true cost. The fix is a price floor per package built from hours at a fully loaded wage plus product and bay time, and a monthly view of detail labour as a share of detail revenue. Packages that cannot clear the floor get repriced, rebuilt or retired; the ones that clear it get sold harder, especially through the spring rush when detail demand peaks. Scheduling belongs in the same view: detail staff paid through an empty booking calendar are the cost line that turns a profitable menu into a losing department.
The second site is a financing file, not a leap
Wash expansion is bought in large, slow pieces: land, construction or an acquisition, equipment, then months of member ramp before the new site carries itself. The model that decision deserves is built from your first site's own history, how fast members actually accumulated, what labour and utilities truly run per car, what a salt season is worth, with a downside case where the ramp takes twice as long. Sometimes the model says wait, and that answer is far cheaper heard early than discovered mid-construction.
When it says go, the same numbers become the lender package: statements a bank can rely on through Compilation Engagements, the facility shaped and negotiated through Business Financing Advisory, and a structure that respects the land-and-operations split covered on our incorporation page. Walla Assaf spent years in banking and corporate finance before public practice, so the file is assembled the way a credit committee will actually read it, debt service tested against the slow ramp rather than the brochure one.
The ongoing engagement is a monthly Fractional CFO rhythm: revenue per member, churn split by cause, peak capture, detail labour share, and cash measured against the debt stack, for operators across Mississauga and the GTA.
