Fintech Platform: Streamlined Invoicing and Estimates — project web and mobile interfaces

The Challenge

Small businesses, freelancers and agencies needed a clearer way to prepare commercial documents and track them through their lifecycle. Manual calculations and disconnected customer information made routine billing work harder to coordinate.

Core Features

  • Invoices and estimates with tax and discount calculations
  • Customer records and multiple-currency support
  • Document status tracking from draft through paid
  • Estimate-to-invoice conversion and PDF/email delivery

The Delivered Solution

CodeNax implemented a connected billing workflow with shared customer information, payment terms and document-generation capabilities. The application organizes estimates and invoices around consistent records, reducing the need to repeat information across separate tools.
