How do you bid on janitorial cleaning?

I would recommend that all professional bids be in writing, on formal letterhead and mailed or hand delivered to the company that you are proposing your bid for. All bids should be signed by both parties, once agreed to and include:

• A Cover Page
• Introduction Letter
• Cost
• Service Requirements
• Terms
• References

There are several online commercial cleaning bid generators, example below, that you can use to input the information based on your client and generate a professional bid that you can print and send to your potential client. This site also offers a commercial cleaning calculator that can give you an estimate for the cleaning based on square footage, type of office, hourly wage of workers and clientele.
