Hi @Rebecca77, thanks for joining the conversation in the QuickBooks Community! 

I see where you're coming from. Using the notes field so that technicians can see customer history is a great idea, but definitely see where that limit could put a wench in things. 

One option in the meantime could be to use the notes field to link an external notes document. Alternatively, you can explore our library of third-party apps where there may be a great solution for sharing technician notes.
