A. Sales of wine or beer between wholesale and retail licensees of the board authority shall be for cash paid and collected at the time of or prior to delivery, except where payment is to be made by electronic fund transfer as hereinafter provided in this section. Each invoice covering such a sale or any other sale shall be signed by the purchaser at the time of delivery and shall specify the manner of payment.

B. "Cash," as used in this section, shall include (i) legal tender of the United States, (ii) a money order issued by a duly licensed firm authorized to engage in such business in the Commonwealth, (iii) a valid check drawn upon a bank account in the name of the licensee or permittee or in the trade name of the licensee or permittee making the purchase, or (iv) an electronic fund transfer, initiated by a wholesaler pursuant to subsection D of this section, from a bank account in the name, or trade name, of the retail licensee making a purchase from a wholesaler or the board authority.

C. If a check, money order, or electronic fund transfer is used, the following provisions apply:

1. If only alcoholic beverage merchandise is being sold, the amount of the checks, money orders, or electronic fund transfers shall be no larger than the purchase price of the alcoholic beverages; and

2. If nonalcoholic merchandise is also sold to the retailer, the check, money order, or electronic fund transfer may be in an amount no larger than the total purchase price of the alcoholic beverages and nonalcoholic beverage merchandise. If a separate invoice is used for the nonalcoholic merchandise, a copy of it shall be attached to the copies of the alcoholic beverage invoices which that are retained in the records of the wholesaler and the retailer. If a single invoice is used for both the alcoholic beverages and nonalcoholic beverage merchandise, the alcoholic beverage items shall be separately identified and totaled.

D. If an electronic fund transfer is used for payment by a licensed retailer or a permittee for any purchase from a wholesaler or the board authority, the following provisions shall apply:

1. Prior to an electronic fund transfer, the retail licensee shall enter into a written agreement with the wholesaler specifying the terms and conditions for an electronic fund transfer in payment for the delivery of wine or beer to that retail licensee. The electronic fund transfer shall be initiated by the wholesaler no later than one business day after delivery, and the wholesaler's account shall be credited by the retailer's bank no later than the following business day. The electronic fund transfer agreement shall incorporate the requirements of this subdivision, but this subdivision shall not preclude an agreement with more restrictive provisions. For purposes of this subdivision, the term "business day" shall mean a business day of the respective bank;

2. The wholesaler must generate an invoice covering the sale of wine or beer, and shall specify that payment is to be made by electronic fund transfer. Each invoice must be signed by the purchaser at the time of delivery; and

Further, wholesalers shall report to the board authority any invalid checks or incomplete electronic fund transfer reports received in payment of wine or beer when either (i) any such invalid check or incomplete electronic fund transfer is not satisfied by the retailer within seven days after notice of the invalid check or a report of the incomplete electronic fund transfer is received by the wholesaler, or (ii) the wholesaler has received, whether satisfied or not, either more than one such invalid check from any single retail licensee or received more than one incomplete electronic fund transfer report from the bank of any single retail licensee, or any combination of the two, within a period of 180 days. Such reports shall be upon a form provided by the board authority and in accordance with the instructions set forth in such form.
