Payment operations and ledger infrastructure for bank transfers
ProPay integrates with Modern Treasury to execute validated contractor and supplier payments. Modern Treasury provides payment operations and ledger infrastructure for companies that move money programmatically at scale, tracking every transfer against an internal ledger. ProPay writes payment instructions in only after an invoice passes authorization.
Modern Treasury provides payment operations and ledger infrastructure for companies that move money programmatically at scale, tracking every transfer against an internal ledger. For ProPay, Modern Treasury is downstream of a decision already made, the ledger and payment execution layer ProPay can write validated contractor and supplier payments into. Nothing reaches Modern Treasury until ProPay has validated the invoice against the authorization record that approved the work.
What ProPay sends to Modern Treasury
ProPay validates contractor and supplier invoices against the authorization decision that approved the repair or parts order, the same decision that carried a confidence level and a documented reason at the time it was made. Only invoices that pass that check reach Modern Treasury.
Every payment instruction ProPay sends to Modern Treasury traces back to a specific claim: a validated invoice, an authorization decision made at a known confidence level, and, where a homeowner was involved, the SMS conversation that confirmed the work was done.
That’s what Modern Treasury receives: a payment instruction with the underlying claim, invoice, and authorization already reconciled, not a raw invoice needing separate review.
How the Modern Treasury connection works
ProPay writes payment instructions into Modern Treasury through its API, with each transfer tied back to the invoice and authorization record that approved it.
A Forward Deployed Engineer maps ProPay’s payment records to Modern Treasury’s chart of accounts and approval structure during deployment, so what lands in Modern Treasury fits how your finance team already reconciles spend.
What stays in Modern Treasury
Modern Treasury continues to own the actual disbursement, reconciliation, and financial reporting exactly as it does today. ProPay supplies validated payment instructions; Modern Treasury remains the system of record for the money itself.
Data handling and security
Payment data written into Modern Treasury comes from a company-specific ProPay instance, one client’s financial data is never accessible to another. ProPay is SOC 2 compliant, with both Type I and Type II audits complete.
Every payment ProPay sends to Modern Treasury is logged alongside the authorization decision and confidence level behind it, so any payment landing in Modern Treasury is traceable back to the claim that generated it.
Deploying the integration
A dedicated Forward Deployed Engineer sets up the Modern Treasury connection to match your chart of accounts and payment approval structure before any live payments flow through it.
