The database Entry no. 021
The night shift
Haley Gallagher's husband was working security at a bar when they noticed nobody was happy with the cleaners. They asked for the contract. Moonlight Commercial Cleaning booked $100,000 of work in its first nine months, turned over $170,000 in its first full year, and grew to nine employees, all after their day jobs.
The best businesses in this ledger start with someone noticing a job being done badly. Haley Gallagher's husband was working security at a bar; the cleaning was mediocre and the manager was unenthused about his provider. They asked whether they could take the contract. The manager owned a second bar across the street, and gave them that one too. Moonlight Commercial Cleaning booked $100,000 of work in nine months and turned over $170,000 in its first full year, run entirely after hours.
Commercial cleaning differs from the residential version documented elsewhere in this database, Mondragon, Ortiz, in one decisive way: the work happens when the customer is closed. Most jobs run two to three hours a night, which means a founder with a day job can build a real company without quitting anything, and staff can be recruited on the promise of picking their own shifts. Nine full-time employees later, that structure is the business.
Sales as a habit, not a budget
Her customer acquisition is the least sophisticated and most repeatable in this database: she eats out, looks around, and if the place is dirtier than her crews would leave it, she introduces herself to the manager and hands over a card. Inbound leads from directories get an email so short it barely qualifies as a pitch, an offer to come by and quote. The insight underneath is that most commercial cleaning contracts are lost by incumbents rather than won by challengers, so the winning move is simply being present at the moment of dissatisfaction.
Most commercial cleaning contracts are not won. They are inherited from someone who got sloppy. The category, summarized
Why this entry earns its place
Because it documents the stage most publications skip: the first year, with a day job, before the business is impressive. $170,000 is not the biggest number in this category, where Joshua Brown reports around $2 million. It is the number that comes first, achieved by two people cleaning bars after midnight and asking strangers for work. Every large figure in this ledger has a year like this behind it.
Common questions
How much can a commercial cleaning business make in year one?
The documented case: $100,000 booked in nine months, $170,000 in the first full year, built entirely after hours. Commercial contracts are larger and more predictable than residential jobs, which is why year one can look like this.
How do you get commercial cleaning contracts?
By showing up where the incumbent is failing. Gallagher hands a card to managers of restaurants she notices are dirty, asks directly for contracts, and answers directory leads with a two-line offer to come quote. No advertising budget appears anywhere in the story.
Can you run a cleaning business alongside a full-time job?
It is arguably the best trade for it, because the work happens after the customer closes. Jobs run two to three hours at night. Gallagher's team grew to nine employees while the founders kept their day jobs, and staff stayed because they choose their own shifts.
