Montana set a record with $326.9 million in 2025 cannabis sales, 90% of it adult-use, on a market made up largely of small independent dispensaries. Bank-to-bank ACH settles the full basket next day on federally regulated banking rails, with no card network in the transaction.
The short version
- Montana set a record $326.9M in 2025 sales.
- Most stores are small, owner-operated businesses.
- A 90-day funds hold is proportionally devastating at that scale.
- Bank-to-bank ACH runs on federally regulated banking rails with next-day settlement.
The Montana market, in numbers
Montana recorded a record $326.9 million in cannabis sales in 2025, slightly above $324.3 million in 2024, according to the Department of Revenue. About 90% was adult-use; medical sales have fallen sharply since adult-use began in 2022.
Most Montana dispensaries are genuinely small businesses: owner-operated, often a single location, without the reserves a multi-state operator carries. Adult-use purchases are taxed at 20% and medical at 4%, which generated about $60 million in 2025.
Why card processing closes in Montana too
The mechanism is national, not local. Card networks require every merchant to be classified with a four-digit merchant category code when an acquiring bank boards the account, and there is no code for state-licensed cannabis. A Montana-licensed dispensary accepting cards is boarded under a category that does not describe it, and network monitoring is built to find exactly that mismatch.
Montana’s own rules do not change this. State licensing determines whether you can operate; card network operating rules are written against federal law, which has not moved. The sequence is the same everywhere: the account boards, it works for a while, monitoring flags the mismatch, and the account terminates with settled funds held, commonly for around 90 days.
Cashless ATM and PIN debit programs are common among Montana dispensaries and carry the same underlying structure regardless of how the terminal is labeled at the counter.
Bank-to-bank ACH as the alternative
ACH moves money directly between the customer’s bank account and the merchant’s, on federally regulated banking rails. There is no card network in the transaction, so no merchant category code applies and there is no network monitoring comparing behavior against a coded category.
At the counter the customer scans a QR code with their phone camera, connects their bank once in about thirty seconds, and confirms. No app download. Every purchase after that is a single confirmation, typically under twenty seconds. Greencard Payments platform data puts the repeat rate at roughly 87%. Funds settle next day into your own account, and cash acceptance is unaffected — this is an addition to the payment mix, not a replacement.
The economics of a very small store
Payment advice written for multi-state operators does not transfer to Montana. A single-location store cannot self-insure against a funds hold, cannot absorb the cost of a mid-year system migration, and cannot afford a payment arrangement that fails without warning.
What a small operator can use is a rail that settles next day into their own bank account, charges one flat fee per transaction with no monthly or setup fee, and does not require replacing the point-of-sale they already paid for.
The dashboard side matters too. Refunds, date-range reporting to PDF or CSV, and transactions that can post to QuickBooks automatically cut into the Sunday-night bookkeeping most owner-operators know well.
Delivery, online and wholesale
Montana’s driving distances make the in-store counter dominant, but online pickup ordering is growing for customers coming in from out of town. E-commerce prepay collects the full basket before the drive, rather than holding inventory against an unpaid order.
On the supply side, wholesale between licensees still settles largely in cash and checks. B2B invoicing on the same platform settles against a specific invoice, next day, with recurring billing for standing orders.
Availability in Montana
Seay Payments is an Independent Sales Organization. We do not process payments, handle onboarding, or provide ongoing merchant support; we connect licensed operators to the platform and to the team that runs it. Bank-to-bank ACH acceptance through Greencard Payments is offered to licensed cannabis businesses, and the demo confirms availability and fit for your license type, your volume and your bank before anything is signed.
