Smart Invoicing / Missed Revenue System

We are working with a US-based client to build a modern SaaS web application that helps service companies reduce revenue leakage by tracking work, identifying unbilled tasks, and automating invoicing workflows.

The goal of this platform is to help companies reduce revenue leakage by tracking unbilled work, generating invoices, and managing payments efficiently.
