CTR SCHEDULE

I schedule a couple crews in the field, would like a simple schedle to show status/simple calendar. Want to add cusotmer info and details including equipment we work on and set follow up appointments in future for servie. Very simple contact manager and calendar. some status like waiting for parts, need to schedule, scheduled, completed etc. Would need to be able to add new equipment, model and SN as needed. maybe some notes from service call. I currently do not need it to interface with our accounting program MAS
