Most disagreements about cleaning cost come from one problem: people compare prices before they have agreed what is being priced. These guides fix that by working in the order a careful buyer would. First understand how the price is built, then see which factors move it, then write the scope, and only then compare quotes.
Each guide stands on its own, but they build on each other. If you are starting from nothing, read them in the order below. If you already hold quotes that do not seem comparable, start with comparing quotes and then go back to the scope.
How these guides fit together
The first two explain the cost side: how a commercial cleaning price is built and what changes it. The scope guide shows you how to turn your building and expectations into a document every contractor can price the same way. The comparison guide shows you how to read the quotes that come back. Together they cover the middle of the buying process, between deciding you need a cleaner and signing a contract.
For the wider process, including choosing and contracting a cleaner, see the buyer's guide to hiring a commercial cleaner, or start with how commercial cleaning is priced. If you want a scope and quote built for your own building, book a walkthrough.
