How to Verify a Commercial Cleaning Company's Credentials

Published by the ABR team · Updated October 2026

Key takeaways
  • Verify business registration, insurance, workers' compensation status and references before the first visit.
  • Get insurance certificates from the agent when possible.
  • Certifications such as ISSA's CIMS are voluntary and worth asking about, but not required by law.

Credentials tell you whether a company is a real, accountable business. Checking them takes less than an hour.

1. Business registration

In Florida, search the Division of Corporations at Sunbiz.org to confirm the company's legal name, status (active) and registered agent. Check that the name on the contract matches the registration.

2. Local business tax receipt

Most businesses operating in a Florida city or county need a local business tax receipt. Ask for a copy, or check with the local tax collector.

3. Insurance

See commercial cleaning insurance explained.

4. Workers' compensation

Florida generally requires workers' compensation for non-construction employers with four or more employees. The state provides a way to look up coverage and exemptions. Ask for proof and verify it.

5. Employment eligibility and screening

Ask how the company verifies work authorization and screens people who get keys. See background checks.

6. Training records

Ask for documentation of training, especially OSHA topics such as Hazard Communication, bloodborne pathogens where relevant, and PPE.

7. Industry certifications

Voluntary programs include:

These are not required by law. They are one way a company shows commitment to a standard. Ask which programs the company holds and ask for the certificate.

8. References and track record

Ask for two or three references, including one similar to your facility. Ask about reliability, communication and how problems are handled. Ask the company's retention rate.

9. Written policies

Ask about safety, confidentiality, key control and incident reporting.

How to ask: Put your requests in a short email and ask for answers in writing. A good company will respond quickly and completely.
