Coriunder

Run the payment brand, not someone else’s rails.

Coriunder is the white-label infrastructure that lets payment service providers and ISOs run a complete acquiring stack - multi-merchant hierarchies, MID cascading, fee templates and settlement automation - under their own brand.

How it works

How PSPs use Coriunder day-to-day

1

Onboard

New merchant submits an application; rules engine scores, provisions MIDs, assigns fee templates and routes to the right acquirers - without human intervention for the standard cases.

2

Operate

Routing, risk and fee logic run continuously. The team monitors only exceptions: unusual decline patterns, merchants approaching reserve thresholds, chargebacks needing response.

3

Settle

Settlements run on the schedule you set, with full breakdowns per merchant. Wires go out to merchant accounts; reserve releases follow your hold-and-release policy.
