We sometimes have to make multiple trips on-site for a particular issue/ticket. It would be helpful to have a customer sign off on Every time we are on site as we have had customers try to say that we were never on site to help them, etc. to get out of paying their bill. We want to acknowledge every single on-site visit. In our environment, we are not using Customer Portal, our customers call in to the shop to start tickets, so I want them to sign on our phone/Field Tablets that they acknowledge the appointment times, notes, etc.
