How can a vendor/supplier be fraudulent?
A valid vendor may have gone out of business officially, yet is still billing the client as if they were still providing a service. A vendor “representative” with fake credentials and materials can present themselves to the client. Business “identity theft”; not shipping the correct products; not issuing credits for returned products; charging more than the contracted rates; being completely “fake”, charging inflated freight fees; billing incorrectly for taxable items, then retaining the difference and so on.
