I have been doing time-tracking and billing using Excel for a number of years. Now that I am doing more contract engineering work for more stations that system is becoming somewhat cumbersome. Anyone have a suggestion for software that will do this for me? I have some clients that are charged an hourly rate for work. other pay for a flat number of yours a week and anything over that number of hours are billed hourly. All clients are billed for parts and supplies for parts and supplies. And all clients are charged when I work remotely to resolve problems or change configuration.
