Timely payment for nonconstruction services.

The time at which payment is due for a purchase other than construction services by a local governmental entity must be calculated from:

(1) The date on which a proper invoice is received by the chief disbursement officer of the local governmental entity after approval by the governing body, if required; or

(2) If a proper invoice is not received by the local governmental entity, the date:

(a) On which delivery of personal property is accepted by the local governmental entity;

(b) On which services are completed;

(c) On which the rental period begins; or

(d) On which the local governmental entity and vendor agree in a contract that provides dates relative to payment periods;

whichever date is latest.
