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 South Carolina charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Whitmire 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.
South Carolina does not charge sales tax on commercial cleaning services, so a Whitmire cleaning quote is the whole price. 6% state rate plus voter-approved local option (commonly +1%).
South Carolina does not license commercial cleaning companies, so there is no state registry for Whitmire buyers to check - verification falls to insurance certificates, written scope and references, which is exactly why those three matter here.
South Carolina janitors and cleaners earn a median of $14.99 an hour per federal wage data, which is the labor floor under every Whitmire cleaning quote - labor is roughly the whole cost structure in this trade.
Most states do not license commercial cleaning companies, which surprises buyers who assume there is a board to check. What South Carolina does or does not require - and what that means for verifying a Whitmire contractor - is set out below, with the state's own source next to it.
Cleaning is labor, and labor is priced locally. What South Carolina sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Whitmire quotes than any vendor's sales pitch does.

What South Carolina adds to a cleaning contract
| Question | South Carolina answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - 6% state rate plus voter-approved local option (commonly +1%). SC taxes tangible personal property and only enumerated services - the SCDOR page lists communications, telephone, fax, streaming and database access; cleaning/janitorial does not appear. |
| Licence or registration required | No state licence for cleaning companies - No state janitorial license; a SC cleaning business registers its entity with the Secretary of State and opens a business tax account / Retail License with SCDOR via MyDORWAY. Municipal business licenses apply locally. |
| Median janitor wage (federal data) | $14.99 per hour |
| State minimum wage | $7.25 |
South Carolina's 6% sales tax covers goods and a narrow enumerated service list that stops short of janitorial work, so cleaning contracts are typically quoted with no sales tax added.

Why South Carolina rules move Whitmire 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 Whitmire buyer can verify before signing.
What this means in Whitmire
A certificate of insurance proves someone had coverage on the day it printed. It confers no rights on you, it does not obligate the insurer to notify you if the policy lapses, and the limits shown may already be partly consumed. Ask for the certificate from the broker, name your entity as additional insured, and re-request it at renewal.

Common questions
How long are commercial cleaning contracts?
Twelve months is the private-sector norm, and automatic renewal is close to universal. The common evergreen wording continues the agreement for successive twelve-month periods without an 'unless you give notice' qualifier, so the exit depends entirely on a separate notice clause - commonly 30 days before the term ends. Calendar that date the day you sign.
Do I still need pandemic-level disinfection?
Federal guidance now tells buyers to determine whether disinfecting is necessary at all before purchasing disinfectants, and notes that disinfectants - which EPA regulates as pesticides - are more hazardous than plain cleaners. Routine whole-building fogging sold as standard is worth questioning; targeted disinfection of high-touch surfaces where circumstances warrant it is a different conversation.
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 do I compare two very different cleaning bids?
Normalize three things before you look at price: total cleanable square footage, frequency per area, and exactly which specialty services are inside the monthly fee. Most large gaps between bids disappear once those are matched - and the ones that survive are usually explained by staffing model or supervision, which is worth paying for.
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.
