Automated Invoice Processing

The Challenge

Managing accounts payable was a bottleneck. The client processing thousands of invoices monthly relied on manual data entry, leading to frequent errors, lost documents, and delayed payments. They needed a solution to ingest invoices from various sources (email, scan, portal), extract key data fields (vendor, date, line items, total), and push it directly to their ERP system.

The Solution

We built an intelligent invoice processing pipeline called "Vellum Invoices". It leverages computer vision and LLMs to understand document layout and context, achieving near-perfect extraction accuracy even on non-standard invoice formats.

• Multi-Modal Ingestion

  Automatically pulls invoices from email attachments, S3 buckets, and direct uploads, supporting PDF, JPG, and PNG formats.

• Adaptive Extraction

  Unlike traditional template-based OCR, our LLM-powered engine adapts to new invoice layouts instantly without manual configuration.

• ERP Sync

  Validated data is automatically formatted and pushed to NetSuite/QuickBooks, creating bills and attaching the original document image.

System Architecture

A serverless, event-driven pipeline optimized for scalability and security.
