California did about $4.06 billion in 2025 cannabis sales across roughly 1,412 licensed retailers, down about 8% in a fourth straight year of contraction. Bank-to-bank ACH settles the full basket next day on federally regulated banking rails, with no card network in the transaction and therefore no merchant category code to mismatch.
California is the only market where the biggest number in the country sits next to the steepest sustained decline.
The short version
- California did roughly $4.06B in 2025 sales, down about 8% and contracting since 2022.
- Roughly 1,412 licensed retailers compete against a large untaxed illicit market.
- Thin margins make a 90-day funds hold after a card termination existential rather than annoying.
- Bank-to-bank ACH runs on federally regulated banking rails with next-day settlement.
The California market, in numbers
California recorded roughly $4.06 billion in legal cannabis sales in 2025, down about 8% year over year. It remains the largest legal market in the United States by a wide margin, and it has now declined every year since its 2021 peak.
Roughly 1,412 licensed retailers operate under the Department of Cannabis Control. Average retail price sits near $9.80 per gram, and the state collected about $640 million in cannabis tax in 2025 — a tax burden that stacks state excise on top of local taxes that vary city by city.
The competitive pressure is not mainly from other licensed stores. It is from an illicit market that pays no excise, no local tax and no compliance cost, and that is a structural margin problem no payment method fixes.
Why card processing closes in California 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 DCC-licensed California retailer accepting cards is boarded under a category that does not describe it, and network monitoring is built to find exactly that mismatch.
California’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 California retailers 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.
Tax stacking, thin margins and basket size
California layers state excise, state sales tax and a local cannabis tax that varies by jurisdiction, so the number at the register is materially above the shelf price. That is exactly the point where a customer paying with what is in their wallet trims the basket.
Cash caps the basket at the wallet. Cashless ATM caps it at rounded cash-back increments, with change handed back and the difference left on the counter. Paying from a connected bank account charges the exact total, tax included, which is the one lever on average order value that does not require cutting price.
For operators fighting an untaxed illicit market on price, holding basket size without discounting is not a nice-to-have. It is most of the available strategy.
Delivery, online and wholesale
California has the deepest delivery market in the country, and delivery is where card workarounds break down worst — drivers carrying cash floats and mobile terminals. SMS pay links settle the order before the vehicle is dispatched. E-commerce prepay collects the full basket at online checkout rather than reserving 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, and every transaction posts to QuickBooks automatically.
Availability in California
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.
