Hello, I just negotiated a contract with a construction company. I am ltd. They said for time being they will pay me slightly less of my asking fee but will cover all expenses. I asked them to clarify what expenses but they sort of did not specify. I am in the process of writing my agreeing letter and what to include expenses section in there from my side. My service will be conducted 2 days from my office and 2 days traveling to site per week for the next 6 months. It involves computer work, meetings, site observation. I plan include things like travel tickets milage and printing costs. Anything else I should be recharging?
