The LACPC is a participant-directed cooperative joint commission for Louisiana municipalities and local political subdivisions.

Developed in accordance with the Local Services Law (La. R.S. 33:1322 et seq.,), which allows political subdivisions to cooperate and administer purchasing of materials, supplies and equipment through a joint commission, the new LaMATS-administered commission invites all Louisiana local governments to join, free of charge or obligation, by passing the appropriate resolution and appointing a commission representative.
