Your rules, handled

Montana’s tax rules and purchase limits are written into CannAgent’s compliance engine from the rule text. Where a figure still waits on an answer from the CARD, it is flagged against the rule rather than guessed.

What we have written for Montana

Montana coverage is written against CARD rules: the county opt-in and opt-out map under I-190, the 4%-versus-20% medical and adult-use split, the no-sales-tax framework, the one-ounce equivalency ARM 42.39.118 sets, and Metrc reporting. We say what is not built for Montana before you sign.
