The Project field is required when Creating or Editing a job.
The Project field allows you to name and group jobs in a sensible way, for example, by assigning your external job reference to Flow jobs.
There's no 'right way' to name your Projects; it depends on your way of working. The important thing is to be consistent.
If you already have a job reference number maintained outside of Flow, this is probably the best reference to use for your Project and works well if you use a 'global' prefix for your job numbers, or client specific prefixes.
Global prefix example: J0123
Client prefix example: ACME00122
The advantage of this option is that you can easily cross-reference Flow jobs with your external system of record.
The second option for naming your projects is to use a general description of the work.
Example: Asbestos Demolition Works
This project naming convention is a good, low maintenance option if you don't have an external job reference.
Another option is to name your projects according to the first line of the address.
Example: 11 Teapot Studios
You're not limited to the Project formats above. Perhaps you'd like to combine two of these options or come up with your own Project format?
Example: ACME00122 - Asbestos Demolition Works
It's up to you!
