Bluefyn checks every fee you pay and every invoice you send against your contracts.

One standard for everything you pay and bill.

FX, provider and network fees, client billing and AI usage, all checked against the terms you agreed.

FX conversion

Every provider says which benchmark it prices against. Bluefyn holds it to that source, checking each conversion’s rate, spread and timestamp, so you see what the market cost and what your provider added.

New product launches

Launch without undercharging. Bluefyn checks your pricing and billing from the first transaction.

AI and token spend

Link every token to the customer who used it, add your spread and bill them in real time, to any account you choose. Our multi-account AR subledger connects to your systems and reconciles itself, so no one matches payments to invoices by hand.

Provider intelligence

See which providers are live around the world and which are the best fit for your routes. We’re not tied to any of them.

Agent-initiated payments

Every payment, whether a person or an agent starts it, still has to match a contract. Bluefyn traces each one back to its terms and evidence.

  • Payment providers
  • Banks
  • Accounting
  • CRM
  • Slack
  • MCP

Works on top of what you already use.

Bluefyn sits above your payment providers, banks and tools, and checks every transaction as it happens. Nothing gets ripped out or replaced.
