S.C. Code Ann. § 37-15-60: Use of simulated checks or invoices restricted.

In connection with a consumer transaction, no person may issue any writing that simulates or resembles:

(1) a check, unless the writing clearly and conspicuously discloses its true value and purpose, and the writing would not mislead a reasonable person; or

(2) an invoice, unless the intended recipient of the invoice has contracted for goods, property, or services for which the issuer seeks proper payment.
