Company J adopts different processing procedures for two different types of returns. For unopened returns, the company will treat them as brand-new goods and re store them for direct sales. For the second kind of return, the company will send the unsealed return to the return authorization department for return, replacement or repair. Unsealed return documents cannot be received as secondary sales. When the first kind of return is transported to the warehouse management department, the corresponding return voucher is generated, and the received goods are included in the warehouse inventory; The second kind of return is placed in the designated location, which will not cause the change of warehouse inventory. The company requires the internal audit department to conduct regular spot checks to ensure that the returns are handled reasonably.
