Guides for resellers
Practical answers for businesses that buy and sell wholesale and liquidation lots. Each guide is written by the ZipToSale team and dated; tax-related guides carry a general-information notice. They're general information, not tax or legal advice. A new guide is published every Tuesday. For the document each state uses, see resale certificates by state.
