Miss. Code § 19-13-25
All claims filed for allowance by a board of supervisors which are based upon a sale or sales of any personal property shall be sufficiently itemized to show in detail the kind, quantity and price of the articles sold. Claims covering the sale of lumber shall be itemized so as to show in detail the grade or grades thereof, the amount of each different size of lumber covered by said invoice or statement, together with the total number of feet of each different grade and size, and the price per thousand feet at which it is sold, stated separately for each different grade and size. Each itemized invoice or statement so filed shall be accompanied by either (1) a receipt, in like detail, properly dated, and signed by a public officer, agent or employee authorized to accept delivery of such property, or, (2) a bill of lading or shipping receipt issued by a common carrier making delivery of such property, the rules of which carrier require a receipt to be given by the consignee on delivery, or (3) an affidavit of the seller, his agent or employee, showing how, where, when, and to whom delivery of such property was made. Where an affidavit is filed as proof of delivery, if delivery was by mail, the affidavit must have attached thereto a post office registry or insurance receipt, and if delivery was made by car, truck, or other public or private conveyance or means, the affidavit must state the name and address of the party actually making the delivery, and the make and license number of any car or truck used therein, as well as the other matters above required. The person so mailing or making actual delivery of such property shall, for the purpose of making such affidavit only, be considered an agent or employee of the seller. It is expressly provided, however, that no claim not first filed with the clerk of the board of supervisors shall be allowed until the seller has filed such claim in accordance with the requirements of this section.
