Enterprise and custom solutions

No — you don't need a finished technical document to get started. Our process begins with a collaborative Scoping Call, where our Product Manager and Solution Architects work with your team to define the scope, design the ledger structures, and map out compliant money flows. You bring the business goal; we turn it into a technical plan.

It depends on the scope agreed during the Scoping Call, but most custom projects go from kickoff to a working integration in weeks, not months. Because you build on our already-regulated rails, you skip licensing and compliance setup and can start earning as soon as your flows go live. You'll get a concrete estimate once the scope is locked.

Enterprise and custom work is priced per project, based on the scope, integrations, and card programs you need. After the Scoping Call our team estimates the custom work and gives you a clear, upfront quote — there are no hidden platform fees, and you know the full cost before development starts.

Yes. Finsei connects to your existing ERP and CRM systems through custom API integrations, so payments, cards, and account data stay in sync with the tools you already use. We support both standard connectors and bespoke integrations built around your architecture — your team keeps working in its own systems while Finsei runs the financial rails underneath.
