How to start a commercial cleaning business

Commercial cleaning is one of the few trades where a $3,000-a-month contract can start from a $600 kit and a clean van. The work is unglamorous and recession-resistant: offices, medical suites, and warehouses get dirty on a schedule and pay monthly by invoice. But the money lives in recurring B2B contracts, not one-off house cleans, and holding one is a different game than doing the cleaning. Here is how to set up the business so it survives the day you sign one.

Pick a lane before you pick a name

“Commercial cleaning” is not one business. General office janitorial, medical and dental, post-construction cleanup, floor care, and warehouse work are five operations with different gear, pricing, and certifications. Medical pays more but demands bloodborne-pathogen training and OSHA compliance; post-construction pays well but is feast-or-famine. General office is the easiest entry: predictable scope, nightly frequency, and 12-month agreements.

Pick one lane to start, because specializing lets you quote faster, buy the right gear once, and say “we do medical suites” instead of “we clean stuff,” which is what wins bids. If you are torn between commercial and the lower-barrier, smaller-ticket residential route, the step-by-step starter guide walks the fork.

Register the entity and get the right insurance

To bid commercial work you almost always need a registered business with a tax ID and real insurance certificates, because the facility manager’s lease and policy require it. In order: form an LLC ($50 to $500 in filing fees) to keep a slip-and-fall claim away from your house; get a free EIN from the IRS; open a business checking account; buy insurance (the real gate, below); and check local licensing, usually a general business license ($50 to $400/year). See set up and register your cleaning business and the checklist of what you need.

Gear, supplies, and what to price

The equipment mistake is buying a $4,000 ride-on scrubber before you have a floor to clean. Match gear to your signed accounts:

A solo office operator is fully equipped for $600 to $1,500; the heavy machines are purchases you make once a contract justifies them. For the full kit, see buying equipment and supplies.

On pricing, routine janitorial goes per square foot ($0.05 to $0.20, dropping as square footage rises) and variable-scope work like post-construction goes per cleaner-hour ($25 to $45). Quote it to the client as a monthly recurring number, because recurring revenue is why commercial beats residential. Net margins land at 10% to 28% after labor (45% to 55% of revenue), supplies, and overhead, so a bid with no room for the cleaner’s wage buys you a night job, not a business.

Hire it out or clean it yourself

Every growing cleaner hits the same fork: when you can no longer clean every account yourself, do you hire W-2 employees or subcontract on 1099?

The decision rule is W-2 for recurring, subcontract for surge: staff steady nightly accounts with employees you control, and use vetted subcontractors only for one-off overflow like a post-construction rush. Misclassifying nightly staff as 1099 to dodge taxes is a common audit trigger. The hire and train staff guide covers the checklist systems that hold quality when you are not on site.

Run the route so contracts renew

Commercial cleaning is a route business, and your real constraint is drive time. Concentrate your first accounts in one commercial district or medical corridor so a crew hits three buildings a night without burning an hour driving between them. A dense cluster of mid-size accounts beats trophy contracts scattered across the metro; the ideal-locations guide shows how to read a market for cleanable density.

Contracts are kept or lost on consistency. Operators who renew run a written scope checklist per account, do monthly walk-throughs, and answer complaints within hours. A facility manager does not fire you over one missed trash can; they fire you when the miss becomes a pattern.

The two things you should not DIY

Once the operation is real, the bottleneck moves from cleaning to getting found, and a website and paid ads are easy to do badly and expensive to get wrong.

A good cleaning website is a measurable discipline, not a design opinion. It loads in under three seconds, puts a tap-to-call and quote-request button in thumb’s reach on mobile, names your service area and lane above the fold, and turns a facility manager who clicked at 11pm into a booked walk-through. Most cleaning sites are pretty brochures that quietly leak every visitor. We build cleaning sites engineered around that one job.

The same logic applies to the paid channels that feed it. Google Ads, local service ads, and paid social can fill a route fast or quietly burn $1,500 a month on clicks that never call, depending on how they are built. Learning that on your own ad budget is the expensive way; for the full lead engine, see our services.
