Quick answer

Fiserv runs many core variants, so the first step is confirming your exact core (DNA, Premier, Portico, XP2, or CUnify) is supported with a real-time, in-production integration. Cotribute is a Fiserv AppMarket Partner with real-time integrations across these cores, and core connectors are included — there is no separate connector fee.

Fiserv powers a huge range of banks and credit unions across several core platforms — and ‘we integrate with Fiserv’ is not specific enough. Your evaluation has to confirm your exact core, in production, in real time.

Step 1: Name your exact Fiserv core

Fiserv DNA, Premier, Portico, XP2, and CUnify are different platforms with different integration paths. Ask every vendor to confirm a live, in-production integration with your specific core — not the Fiserv brand in general, and not a roadmap item.

Step 2: Require real-time writeback

As with any core, batch integration creates manual work and delays funding. Require real-time creation of accounts and members in your Fiserv core, with correct product and field mapping and clean error handling.

Step 3: Cover consumer and business

On bank cores especially, business account opening matters. Confirm the platform automates KYB, Secretary of State checks, and FinCEN CDD beneficial-ownership collection, and writes the funded business account back to your Fiserv core.

No connector fees

Cotribute is a Fiserv AppMarket Partner, and real-time core integrations are included in the platform fee — there is no per-connector charge to integrate with your own Fiserv core.

Step 4: Verify before you sign

  1. Live demo posting to your specific Fiserv core in a sandbox, in real time.
  2. Business account opening with automated KYB, if you serve businesses.
  3. A reference on your exact Fiserv core, at an institution your size.
