Mass. Gen. Laws ch. 29 § 29I
The comptroller shall develop and implement a payment system and regulations for interdepartmental fiscal transactions including interdepartmental service agreements and interdepartmental chargebacks. The chargeback system and regulation shall require state agencies that purchase legislatively authorized goods or services from approved chargeback departments to remit fiscal obligations within 30 days of receipt of notice of said obligation. The comptroller shall submit periodic reports on request to the house and senate committees on ways and means listing those agencies which do not meet the 30 day payment schedule. Said report shall also include but not be limited to the identification of the agency receiving said goods or services and the agency providing said goods or services; provided, that said identification includes the name of the agency and the item number, the goods or services provided, and the amount of outstanding obligation. The comptroller may take such action as the comptroller deems necessary to ensure compliance with the payment obligations under this section.
