Automating Financial Workflows with a Scalable Fintech SaaS Product

About Our Client

A European fintech company focused on simplifying financial operations for small to mid-sized businesses. They envisioned a modular SaaS platform that could automate bookkeeping, reconcile bank transactions, and streamline monthly reporting without the need for traditional accounting software.
