Blind Entry
  
A blind entry is super-sketchy in the eyes of accountants. When there’s a financial entry (say, a payment to someone, or an accepted payment from someone else) with no note of what the transaction is or who it was with...it’s considered a “blind entry.”
Blind entries are what accountant detectives look for when they’re trying to sniff out some fraud, or what they call “cooked books.” If you’re trying to commit fraud by cooking the books, at least try to make it look like you tried, and don’t leave a blind entry, just in case.
