Survey shots and photos of finished work live on the job in Fixington, so they are there when you quote, when you invoice, and when you need to show what you did.
Example
A quote is easier when you can see the consumer unit, the boiler cupboard, or the access you are going to struggle with. Take the photo in Fixington and it sits on that job, not in a camera roll of three hundred other pictures.
When the customer adds a room or questions a line, you still have the picture you priced from.
Photograph the finished job and keep it with the invoice. It is the record of what you left behind, useful if there is a question later, and useful when you want to show the work.
The photos follow the job onto a new phone. They are part of the account, with the customer, the quote and the invoice.
