What the state adds to the price, and what it lets you verify
Federal rules for cleaning contractors are thin; the expensive differences are state-level. What Missouri charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Cowgill labor cost are below with official sources.
Two free marketplace paths: one request brings back multiple vetted cleaning contractors who know they are competing for the account.
Missouri does not charge sales tax on commercial cleaning services, so a Cowgill cleaning quote is the whole price. Sec. 144.020.1 RSMo levies the tax on retail sales of tangible personal property plus a closed list of taxable services: (2) admissions/seating and fees at places of amusement, entertainment or recreation.
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Cowgill that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Missouri janitors and cleaners earn a median of $17.26 an hour per federal wage data, which is the labor floor under every Cowgill cleaning quote - labor is roughly the whole cost structure in this trade.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether Missouri charges sales tax on cleaning services, whether it licenses cleaning contractors at all, and what its wage floor does to labor cost are the three that show up in a Cowgill quote. All three are below with official sources.

What Missouri adds to a cleaning contract
| Question | Missouri answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - Sec. 144.020.1 RSMo levies the tax on retail sales of tangible personal property plus a closed list of taxable services: (2) admissions/seating and fees at places of amusement, entertainment or recreation; (3) electricity, water and gas; (4) local and long distance telecommunications; (5) telegraph message transmission; (6) hotel/motel rooms, meals and drinks; (7) intrastate transportation tickets; (8) rental or lease of tangible personal property; (9) titled motor vehicles, trailers, boats and outboard motors. (Sec. 144.020.1, RSMo) |
| Median janitor wage (federal data) | $17.26 per hour |
| State minimum wage | $15.00 |
Missouri's voter-approved wage schedule pushed the state floor to $15.00 by 2026, more than double neighboring Mississippi's and Louisiana's federal $7.25, making janitorial labor cost swing sharply across state lines in the same region.

Why Missouri rules move Cowgill quotes
Two of the three state variables land directly on your invoice. Sales tax, where a state charges it on cleaning services, is added to every monthly bill - on a mid-size contract that is real money over a year. The wage floor sets the labor cost every bid is built on, which is why identical buildings in different states get materially different quotes. Licensing is the third and it works differently: it does not change the price, it changes what a Cowgill buyer can verify before signing.
What this means in Cowgill
'Bonded' sounds like protection and functions like credit: the bond pays only after an employee is criminally convicted, and the cleaning company repays the surety afterward. If theft protection is what a Cowgill buyer actually wants, the thing to verify is the contractor's own crime coverage and hiring screening, not the word 'bonded' on a flyer.

Common questions
Do I have to pay sales tax on cleaning services?
That depends entirely on your state - most states do not tax cleaning services, but a minority do, and in those states it is a real line on a real invoice: at typical rates it adds several percent to every monthly bill. This site publishes the treatment state by state with the revenue department's own source; check your state's page.
Is it cheaper to pay hourly or per square foot?
Neither is inherently cheaper; they suit different jobs. Hourly pricing runs $25-$75 per worker per hour and fits small or irregular scopes. Square-foot pricing fits predictable routine work and makes budgeting easier. The only fair comparison is to ask every bidder for the all-in monthly total on identical scope and frequency, then divide.
Is a certificate of insurance enough proof?
It is a starting point, not proof. The standard certificate states in its own header that it confers no rights upon the certificate holder - it is a snapshot of what was in force the day it was issued, with limits that may already be partly consumed by other claims. Ask the broker to send it directly, have your entity named as additional insured, and re-request it at renewal.
How much does commercial cleaning cost per square foot?
In 2026 industry ranges, general office space runs about $0.09-$0.17 per square foot per month, medical and healthcare $0.14-$0.29, industrial $0.08-$0.20, retail $0.07-$0.15 and schools $0.07-$0.14. Those figures assume a stated frequency - a per-square-foot price without a frequency attached tells you nothing.
What does floor stripping and waxing cost?
Strip and refinish runs about $0.30-$0.80 per square foot in 2026 pricing, and scrub-and-recoat - the lighter maintenance version - about $0.20-$0.40. Most vendors apply a minimum service fee of roughly $250-$500, which makes small jobs disproportionately expensive per square foot.
