A cleaning invoice is a document that lists the services provided by a cleaning company, along with the price for each service. It also includes the total amount due, payment terms, and contact information for both the service provider and the client. A detailed cleaning invoice may also include information about the date and time of the service, the number of hours worked, the cleaning supplies and equipment used, and any additional fees or discounts. The purpose of a cleaning invoice is to provide a clear and transparent breakdown of the costs incurred for cleaning services rendered, and to ensure that both parties have a record of the transaction.
