Constellation Payments

Constellation Payments is a gateway and merchant services provider with software integration and transactions. The job it does: building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. Alongside the main category they mention Financial Services, Mobile Payments and Payments. They are a very small team, 1 to 10 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.

Constellation Payments is based in Warminster, Pennsylvania and around since 2012. Their site is csipay.com.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. Get the renewal terms in writing before the first invoice.
