Can Lago work with Fiserv?
Lago can be paired with Fiserv through a custom integration. Lago does not list a native Fiserv connector: your team or an implementation partner must build and validate the bridge using Lago webhooks and the provider API.
Lago remains the billing system. Fiserv remains the payment system. This page describes an evaluation path, not a certification or commercial affiliation with Fiserv.
Verify before launch
- Create a test customer and subscription in Lago, then trace an invoice to the payment attempt in Fiserv.
- Confirm how a customer adds or changes a payment method, and how success, failure and retries return to Lago.
- Test partial payments, refunds, disputes and reconciliation against the same invoice IDs.
- Check regional payment methods, security requirements, ownership of support and the total integration work.
