Question: Who is crazier, the MSP who promises to do work for a customer without providing the details of the work to be done, or the customer who doesn’t ask for the details? Answer: Who cares? Either way, it’s a legal disaster waiting to happen.
Service details must appear in your company’s statement of work (SOW). After all, that’s the document that defines the services you provide to your customers and, of course, the document to which your customers will refer when something goes wrong.
