Quantrix

Quantrix, enables organizations to replace spreadsheet-based processes for improved business performance and timely insights. In practice that means accepting cards, bank transfers and wallets online or in person.

It makes the most sense for any business that takes money. Related areas on their profile: Analytics, Finance and FinTech. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

Quantrix is based in Portland, Maine and founded in 2002. More on quantrix.com.

Things worth asking about: rates, payout timing, chargeback handling, and developer tools. Ask for a trial on your own data, not a canned demo.
