Every rail, one API
The right rail for every payment
Keelstone routes each payment over the fastest, cheapest rail that meets your delivery deadline — or you can pin a rail explicitly.
ACH on Keelstone
The workhorse of US domestic payments. Keelstone batches, schedules, and retries ACH credits and debits automatically, with same-day windows when you need them.
- Payroll and contractor runs
- Vendor batches
- Recurring debits

Built for finance teams
Everything around the payment, handled
Approval workflows
Multi-step approval chains by amount, currency, or counterparty. Approvers get the full context — invoice, FX quote, and history — in one click.
Batch payments
Upload a CSV or push via API and pay 5,000 vendors in one batch. Failures are isolated, retried, and reported line by line.
Payment tracking
gpi-level tracking on every rail. See each hop, share a status link with your beneficiary, and stop fielding ‘where’s my money’ emails.
FX at mid-market
Convert at the mid-market rate plus a transparent 0.35% — no hidden spread. Lock quotes for up to 24 hours before you send.
Idempotent API
Every request takes an idempotency key, so a retried timeout never becomes a duplicate payment. Webhooks confirm each state change.
Auto-reconciliation
Payments sync to your ledger with references intact. Keelstone matches confirmations to invoices and flags the rare exception for review.
