The study systematically evaluates eight state-of-the-art multi-modal LLMs (OpenAI GPT-5, Google Gemini 2.5, Google Gemma 3) across three diverse, openly available invoice datasets (Clean Invoices, Scanned Receipts, Scanned Invoices). The datasets vary in quality, layout complexity, and presence of real-world artifacts like skew and handwritten annotations.
Two distinct processing strategies were compared: Native Image Processing, where document images are fed directly to multi-modal LLMs to leverage their visual understanding, and Docling Processing, a two-step approach that first converts images to markdown via Docling before LLM processing.
Feature | Native Image Processing | Docling Processing |
---|---|---|
Input | Raw document images | Markdown text from Docling |
Visual Context | Fully preserved (layout, spatial relations) | Partially lost/abstracted |
Performance (General) | Significantly higher accuracy | Lower accuracy (bottlenecked by OCR/conversion) |
Complexity for LLM | Higher (raw image interpretation) | Lower (structured text input) |
Key Advantage | Leverages multi-modal understanding | Standardized, text-only input |
Best Use Case | Complex layouts, noisy scans | Documents with simple, predictable structures |
The benchmark reveals that native image processing consistently and substantially outperforms structured parsing (Docling) across all datasets and models. Gemini 2.5 Pro achieved the highest overall accuracy, with OpenAI GPT-5 models also performing strongly on clean datasets. Smaller models (e.g., gemma-3-4b-it) showed significant performance drops with direct image analysis, indicating a capability threshold.
The study highlights that while multi-modal LLMs are powerful, there are limitations. Extracting unstructured alphanumeric fields like IBANs remains challenging, and performance on noisy scanned documents needs improvement. Future work should explore specialized models like LayoutLM and LiLT, and potentially fine-tuning for specific document understanding tasks.
Enterprise Process Flow for Document Automation
Optimizing Invoice Processing with AI
A large enterprise faced significant manual effort in processing thousands of invoices monthly, leading to delays and errors. By implementing a multi-modal LLM solution, they automated 85% of their invoice data extraction, reducing processing time by 60% and achieving a 92% accuracy rate on key fields. The visual understanding capabilities of the LLM were crucial for handling diverse invoice layouts and noisy scans, leading to substantial operational savings and improved compliance.
