Here are a few suggestions: 1) allow attachment of pictures or files to the notes 2) You must allow for searches of text in the notes fields!!! 3)Allow for automated emails based upon tags, so a sequence of emails that are separated by a few days when a tag exists. 4)Allow for text messaging SMS / MMS to customers when a phone number exists! You could do an integration with Twilo or something similar.
Thanks for the feedback! Could you elaborate on the types of pictures/files you'd like to attach?
I like the idea of texting/Twilio integration.
