Invoice manipulation is a serious violation of Amazon’s policies and can result in a permanent suspension of your selling privileges. Amazon requires sellers to submit valid, truthful invoices for all inventory purchased from suppliers. These invoices must be accurate, legible, and in accordance with Amazon’s guidelines. Invoice manipulation refers to submitting fake, altered, or misleading invoices to Amazon in an attempt to bypass their policies, misrepresent the authenticity of products, or hide the true source of your inventory.
