I use Google Calendar. You'll start by creating a separate calendar for the tech(s) and share the calendar to parties involved. Here's the workflow I use. Create a new calendar event Appointment Title- Client name and Issue location field- Input address which then links to maps Description- Phone number on first line and notes below Add attachment- Add photo of completed repair ticket when finished Change color to yellow and text tech of new repair on calendar Scheduling- Tech calls client and schedules repair. Updates calendar date/time and changes color to blue. Closing appointment- Tech takes a picture of paper repair ticket, share to google drive folder, and attach to the appointment. Use square for credit card payment, get a check, or invoice later. Color of appointment is changed to green and enter any closing notes in the description. Its free and you only need a cell phone.
