Ohio is the newest adult-use cannabis market in the country and the fastest growing, so most operators are choosing a payment setup for the first time. Bank-to-bank ACH starts on federally regulated banking rails rather than a card workaround, which avoids the merchant category code problem instead of postponing it.
The short version
- Ohio adult-use sales grew roughly 192% in 2025, its first full calendar year of adult-use retail.
- Around 152 dispensaries serve the state, a small store count on a market that passed $1B combined.
- New operators can choose their rails before inheriting a shutdown, rather than after one.
- Bank-to-bank ACH runs on federally regulated banking rails, with next-day settlement.
The Ohio market, in numbers
Ohio opened adult-use retail in August 2024 under Issue 2, and 2025 was its first full calendar year. Adult-use sales came in around $836 million, with roughly $233 million more in medical sales, taking the combined market past a billion dollars. Growth on the adult-use side ran at roughly 192%.
The state is served by around 152 dispensaries, regulated by the Division of Cannabis Control. That is a small store count carrying a large market, which means high revenue per location relative to states like Oklahoma or Oregon.
Why card processing closes here too
Ohio's market being new does not make its card processing different. Card networks classify every merchant 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 dispensary accepting cards is coded as a business it is not.
The pattern that follows is well documented in every older market: the account boards and works, often for months, transaction behaviour diverges from the coded category, monitoring flags it, and the account terminates with settled and unsettled funds held, commonly for around 90 days.
New operators are frequently sold cashless ATM or PIN debit programmes on the basis that they are working right now for other stores. They are. That is the first phase of the cycle, not evidence against it.
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. No card network is in the transaction, so there is no merchant category code to mismatch and no network monitoring comparing behaviour 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 the first 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 continues unchanged.
Building the payment stack once
Ohio operators still scaling have an advantage worth using: the systems chosen now are the ones staff will be trained on, the ones customers will get used to, and the ones the books will be built around.
- The counter. In-store QR, exact basket total, no rounding and no change handed back.
- Delivery and pickup. SMS pay links and e-commerce prepay, so orders arrive paid rather than reserved.
- Wholesale. B2B invoicing with recurring billing, settling next day against a specific invoice.
- The books. Transactions posting to QuickBooks automatically from the first month rather than being reconstructed later.
Retrofitting each of those separately after a shutdown is how operators in older markets ended up with four systems and a spreadsheet.
Availability
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 available to licensed cannabis businesses in Ohio, and the demo is a working session on your actual numbers.
