Hire Modern Treasury Developers for Automated Payment Operations

Connect bank accounts, payment workflows, ledgers, reconciliation, approvals, and reporting through a reliable operational layer. Our Modern Treasury developers help fintech and finance teams automate money movement without losing visibility or control.

Modernize Payment Operations Across Banks and Systems

Moving money is rarely a single API request. A complete payment operation includes counterparties, approvals, payment orders, bank connectivity, status changes, returns, reconciliation, ledger entries, accounting sync, exceptions, and audit trails. When these pieces are split across portals and spreadsheets, finance teams spend too much time chasing what happened.

FintegrationFS helps companies integrate Modern Treasury’s REST APIs, sandbox, webhooks, payment operations, reconciliation, and ledger capabilities with their product and internal systems. We design the workflow around your banking relationships, payment rails, accounting model, approval policies, and support needs.

Why Work With Us?

Payment-operations expertise

We understand ACH, wire, real-time rails, returns, approvals, settlement, reconciliation, ledgers, and the operational edge cases around business payments.

Product and finance alignment

The integration serves end users and internal finance teams, with clear states, exception queues, reporting, and controls.

API and webhook reliability

We build idempotent requests, event verification, retries, reconciliation checks, observability, and recovery instead of assuming every asynchronous event arrives once and in order.

Integration across the finance stack

We can connect Modern Treasury with your product, bank data, ERP, accounting platform, data warehouse, CRM, and internal ledger or subledger.

Support available ACH, wire, and real-time payment workflows across connected banks, with routing and operational logic based on urgency, cost, and risk.

Frequently Asked Questions

1. What does a Modern Treasury developer do?

A Modern Treasury developer integrates payment operations with your product and finance stack. Work may include payment orders, counterparties, approvals, bank connections, webhooks, ledgers, reconciliation, dashboards, and accounting sync.

2. What payment workflows can Modern Treasury support?

Modern Treasury can support payment initiation and operations across connected banks and available rails. The exact ACH, wire, real-time, check, approval, and reporting capabilities depend on your account and banking setup.

3. Can you integrate Modern Treasury with our existing application?

Yes. We can add a dedicated service layer to your current backend, map internal users and transactions, and connect the payment lifecycle without rebuilding unrelated product areas.

4. Can you automate reconciliation?

Yes. We can map payment records, incoming and outgoing bank activity, returns, expected payments, and internal ledger entries, then create exception workflows for unmatched items.

5. Can you connect Modern Treasury with our accounting system?

Yes. We can integrate with supported accounting or ERP tools, or build a custom sync for chart-of-account mapping, journal events, payment status, fees, and reconciliation outcomes.

6. Can you build ledger or wallet functionality?

Modern Treasury provides ledger capabilities that can record balances and transactions. We can design the ledger model and connect it with payment events, but the complete regulated product structure must be reviewed with your banking and compliance partners.

7. How do you handle webhooks and duplicate events?

We verify events, store processing state, use idempotent handlers, manage retries, detect duplicates, reconcile against API data, and alert operators when an event cannot be processed.

8. Is a sandbox available for development?

Modern Treasury provides a sandbox environment for testing API requests without moving real money. We use it for early integration and automated tests before connected-bank validation and production rollout.
