Idaho Code § 50-1018: Payment of claims.

Upon approval of claims by the council, payment may be ordered by warrant or by electronic means, signed by or authorized by the mayor and clerk or by check or by electronic means signed by or authorized by the mayor and treasurer. The order for their payment shall specify the particular fund or appropriation out of which they are payable, as specified in the annual appropriation bill.

(1) Registered warrants as provided in section 31-2125, Idaho Code, or

(2) By issuing its tax anticipation notes as provided in section 63-3102, Idaho Code, or

(3) Short term borrowing not involved with the tax effort in anticipation of approved federal or state grants.
