ACH is the rail cannabis was waiting for.

Credit cards remain off-limits for plant-touching cannabis under current federal guidance — but ACH has always been compliant, has always been legal, and has always been the lowest-cost rail for high-ticket cannabis transactions. BIG MerchantPay packages that rail with Plaid linkage, text-message UX, and no app to download. Onboarded in 3 days, processing the next.

Why cannabis operators choose BIG for ACH.

01

Industry expertise on every account

BIG has been helping cannabis businesses navigate payment complexity since 2008. Our team writes ACH applications correctly the first time, which is why our onboarding times are days, not weeks.

02

Secure and compliant by design

Fully compliant with federal and state banking regulations. We work with cannabis-friendly acquiring banks to ensure every transaction is transparent, traceable, and audit-ready.

03

Lower fees, higher margins

ACH transactions cost a fraction of traditional card processing. You keep more of every dollar — and on the right program, you can pass the cost through to the customer entirely.

Highly recommend—professional, kind, easy to work with.

I'm very happy and satisfied with the service and platform. I've always had someone I can reach out to directly whenever I have questions, and they're always quick to help and follow up. On top of that, they regularly check in just to see how things are going, which I really appreciate. Their pricing is fair, and overall, they're incredibly professional, kind, and easy to work with. Highly recommend!

We have been using Bankcard PIN Debit system for 1 year now and it has been a great help to our canna business. Not only by significantly reducing the amount of cash handling but also by boosting our ADS, and on top of this they have a fast responding help team. Thanks Shane and team.
