I don't think so. You could go buy $1000 worth of gift cards to give to your family on a business credit card versus legitimate business expenses. The receipt shows what you bought, a credit card statement only shows the amount.
No, the CC company actually has line-item information for almost all purchases (fall-back transaction processing and really old terminals are likely excluded).
Theoretically you can get your hands on that information.
that's strictly for reimbursing an employee for an expense.
Good catch. I’ve been audited before, so I err on the side of caution and keep as much documentation as reasonably possible to substantiate business expense claims. Electronic storage is cheap, and audits are unpleasant.
