How do I find out which commercial cleaning clients have a person at the site who can complain?

Ask for a client list showing the named day-to-day contact at each site, and who that person reports to. Then read the complaint and call log by client, ask supervisors which sites have a watchful contact, and visit a few sites to see how that person deals with the crew.

A cleaning client with a watchful on-site contact is not a bad client. It does mean you can see the quality standard every day, and that small lapses reach the decision-maker quickly. Knowing which clients behave this way tells you where to expect scrutiny after the sale.

Start with the records. Ask for the complaint log, emails and call notes. Group them by client and see who raises issues often, who raises them politely and who goes straight to the manager. Look at what was asked, how fast the business answered and whether the same issue returned.

Then ask the supervisors and crew leads. They know which building manager walks the floors at night, which tenant leaves notes, and which contact is easy to work with. Compare their view with the written log. Finally, if you can, meet a few of those contacts with the seller. Ask what they expect from the cleaners and what would make them look elsewhere. A client that likes the crew may stay through a sale. One that already feels let down may not. Note which contacts have changed lately, because a new contact often brings new expectations.

Key takeaways

  • Get the named site contact and reporting line for every client.
  • Read complaint logs by client and see how fast problems were fixed.
  • Ask supervisors which sites have the sharpest eye.
  • Meet a few contacts with the seller to hear what they expect.
