Open Jobs. The bar at the top splits every job by where it stands. Press a count on it, or a view under it (All, Open, Booked, On site, To invoice, Invoiced and Closed), to show those jobs. Press a job to open it under its row.
Each row shows the techs on its visits as initials, green once their visit is done, and the dots before its chip show how far it has come: open, booked, on site, done and invoiced.
Press Add a job for work that did not come in as a request, and pick the customer and site.
When you are waiting on parts, press Hold or close, pick Waiting for parts and say what for. Press Parts are here when they arrive.
To close a job with nothing to bill, or cancel it, press Hold or close and give the reason. Reopen it brings it back.
