It sometimes causes issues with shipping labels. When you try to squish a business name into a "First" and "Last" name line, we get notices that we can't fit that many characters in that field or the label has the company name listed twice with "Attn" listed twice because Turntree also automatically adds "Attn" to the "First/Last" name fields but doesn't mention that. If there is no "Attn" person, I don't want to be forced to create an imaginary one, or squish a business name into a name field when it should be on the company name field only. That causes too many issues afterward and is a pain to deal with.
