If you have office staff you can split the roles.
The benefits are:
Office staff would create the following:
When creating certificates, quotes and invoices, the engineer would just need to click on 'Use Existing Job' option, then enter the inspection results and they are done.
(As all of the customer details have been entered by the office staff)
After that the engineer would check their calendar within the app and is off to the next job.
If the office staff have created the Customer, Job Address, Job, and added a Calendar Appointment for this job, the engineer can open their calendar, tap on the event created for them, and tap 'Create New Record'.
Selecting the correct record or certificate will take them straight into the certificate - no need to select a customer, job address, or job number.
