Using Pictures for Estimate
I find taking pictures to be very useful in preparing the estimate. Many of the clients bring their furniture into my shop to get an estimate. I usually take pictures of it from several angles angles showing everything that I will want to remember. Most of those clients don't want to wait around for me to write up an estimate, so I offer to email the estimate when I'm finished. While the client is still here I spend that time going over everything that needs to be considered, which I also make notes about. I find my notes and the pictures useful when I finally have the time to make out the estimate (which could be minutes, hours, or days later.
Having photos synchronized with online
I take most of me pictures (for estimates) with my smart phono. I have the Google Photo App set up to automatically synchronized/back up all the pictures to my photos.google account.
