Why your 3×/week contract is less profitable than your 5×

Same building, same crew, worse economics. Two structural reasons, and one of them is entirely inside your control.

Two buildings, same size, same soil, same client type. One is cleaned three nights a week, the other five. The five-night account almost always earns a better margin per hour — and operators who price both off the same rate card are quietly subsidising the three-night one.

There are two reasons. One is physical and you can only manage it. The other is arithmetic and you can fix it tonight.

Reason one: soil accumulates between visits

A floor cleaned Monday and again Tuesday has one day of traffic on it. A floor cleaned Monday and again Wednesday has two. Trash is fuller, restrooms need more attention, spots have had longer to set, and the crew spends longer per visit than a straight-line model predicts.

The effect is real but not linear — the second day of soil doesn't take twice as long, it takes somewhat longer. Which is why serious estimating applies a frequency factor to production rates rather than assuming a fixed sq ft per hour:

A factor below 1.00 means your effective square-feet-per-hour drops, so hours per visit rise. At 3× you're baseline; at 1× weekly you're spending meaningfully longer per visit on the same building. If you price a once-weekly account at the same per-visit hours as a five-night account, you have underbid it before you've walked the site.

Reason two: fixed per-visit costs don't care how often you go

This is the bigger one, and it's pure arithmetic.

Every visit carries costs that have nothing to do with building size: drive time, unloading, setting up, locking up, driving back. Call it 25 minutes. That cost is identical whether you're there once a week or five times — but the revenue it's spread across is not.

Now hold the building constant and change only the frequency. At 5× weekly you make 21.7 visits a month and pay that 0.42 hours 21.7 times. At 3× you make 13 visits and pay it 13 times — less in absolute terms, but spread over far less monthly revenue.

Note the five-night account cleans faster per visit — 2.78 hours against 3.00 — because a floor with one day of soil on it takes less work than a floor with two. Travel's share of the night is broadly similar either way.

The real difference shows up when you add the costs that are fixed per account rather than per visit — the supervisor check-in, the client phone call, the monthly invoice, the quality inspection. Those don't scale with visits at all. On the five-night account they're spread across 69 billable hours; on the three-night account, across 44. Same admin, 56% more hours to bury it in.

What this means for how you bid

• Don't run one rate card across frequencies. A single $/sq ft figure applied to 1×, 3× and 5× accounts systematically underprices the low-frequency ones.
• Price travel explicitly, per visit. If it's buried in a blended hourly rate you can't see what a distant one-night-a-week account is doing to you.
• Set a minimum monthly. Below a certain contract value, the admin and travel overhead can't be recovered at any plausible rate. Know where your line is and hold it.
• Route geographically. The single strongest lever on low-frequency profitability is cutting drive time by clustering accounts. Two 1×/week buildings in the same park behave like one visit with a walk between them.

The upsell that isn't a hard sell

When a three-night client asks about going to five, most operators quote 5/3 of the current price. That's usually leaving money on the table in the wrong direction — it overprices the increment, because the extra visits carry no additional account overhead and benefit from a better production factor.

Price the five-night version from scratch, on its own hours. It'll often come out proportionally cheaper for the client and better per hour for you, which is a rare thing to be able to say honestly in a negotiation.
