Custom fields can be set up by support in your account.
Additional fields can be added to Clients, Assets and Jobs.
These can be named for your custom needs.
The technicians can also work with these Extra fields on the Mobile APP.
Some great example from our clients:
Clients: clientcode or client Number if you keep track of them
Clients: Language spoken by the client
Assets: Counter for Coffee Machines (# of coffees made / grinded)
Assets: Counter for Printers (# of pages printed / copied)
Jobs: Additional description of the work
Jobs: Internal note (not shown to the client)
Jobs: Status of the work
Jobs: Further work needed
They are not shown on the Work Order PDF by default, but could be customized to do so.
