Priced like infrastructure.
Usage-based and honest. You pay for what moves — cards, authorizations, transactions and rails — not for a per-vendor stack of invoices you reconcile by hand. Numbers are set per design-partner; there are none invented here.
Issuing
Per active card and per authorization. Virtual and physical on the same model.
Acquiring · Payrithm
Per transaction, interchange-plus. You compose the message; you keep the economics.
Money movement
Per rail, per payout. Route by cost when cost is what matters.
Ledger, rules & disputes
Included — the canonical ledger, the rules engine and the dispute lifecycle aren't an upsell.
One platform, one invoice
The old way is four vendors, four integrations and four reconciliations. StringIO is one model, one ledger and one bill — the reconciliation goes from a team to a query.
