Washington Revised Code Title 82. Excise Taxes § 82.25.040. Itemized invoice requirement--Retailers

(1) Every retailer must procure itemized invoices of all vapor products purchased. The invoices must show the seller's name and address, the date of purchase, and all prices and discounts.

(2) The retailer must keep at each retail outlet copies of complete, accurate, and legible invoices for that retail outlet or place of business. All invoices required to be kept under this section must be preserved for five years from the date of purchase.

(3) At any time during usual business hours the department, board, or its duly authorized agents or employees may enter any retail outlet without a search warrant, and inspect the premises for invoices required to be kept under this section and the vapor products contained in the retail outlet, to determine whether or not all the provisions of this chapter are being fully complied with. If the department, board, or any of its agents or employees are denied free access or are hindered or interfered with in making the inspection, the registration certificate issued under RCW 82.32.030 of the retailer at the premises is subject to revocation by the department, and any licenses issued under chapter 70.345, 82.26, or 82.24 RCW are subject to suspension or revocation by the board.
