A commercial cleaning proposal is an offer or service agreement between a business and a customer that outlines all the details of a planned cleaning project. This includes the scope of work, the timeline for completion, the terms of payment, and any other special requirements. An effective commercial cleaning proposal should provide clear communication of expectations to ensure that all parties involved have a smooth and successful working relationship. It should also demonstrate professionalism and quality assurance by making sure to cover all possible contingencies and offering competitive pricing.
