Duration: 12 months

Team Size: 4 developers

Overview

Parseo represents a breakthrough in automated invoice processing technology. Built from the ground up using modern TypeScript and NestJS architecture, it transforms how businesses handle invoice workflows. The platform combines intelligent document processing, team collaboration features, and powerful integrations into a unified solution that scales from small businesses to enterprise operations.

The Challenge

Businesses needed a comprehensive solution to automate invoice processing with AI-powered document parsing, email integration, multi-tenant team management, and seamless API integrations. The system required enterprise-grade security, real-time processing capabilities, and the ability to handle various invoice formats using OCR and machine learning while maintaining audit trails and detailed analytics.

The Solution

We developed Parseo, a sophisticated NestJS-based invoice processing platform using Domain-Driven Design principles. The solution integrates AI and OCR technology for intelligent document parsing, automated email processing, comprehensive team management with RBAC, real-time job processing, and extensive webhook integrations. Built with enterprise security and scalability in mind, leveraging AI services for accurate data extraction.
