Why AI Beats Templates for Invoice Processing

Drakon Systems··3 min read

If you've used invoice processing tools before, you've probably experienced this: a new supplier sends an invoice, and your software has no idea what to do with it.

That's because most invoice tools rely on templates - predefined rules that map specific locations on a document to specific fields. Move the invoice total to a different corner, and suddenly your "automated" system needs manual intervention.

The Template Problem

Template-based systems work like this:

  1. You receive an invoice from a new supplier
  2. The system doesn't recognise the format
  3. You (or the software) creates a template by marking where each field appears
  4. Future invoices from that supplier use this template

This works... until it doesn't. Here's what breaks:

  • Supplier redesigns their invoice - template becomes useless
  • Invoices with varying line items - templates can't handle dynamic content
  • Multi-page invoices - templates often only work on page 1
  • Slight formatting changes - even small shifts can break extraction

The result? You spend hours maintaining templates instead of doing actual work.

How AI Extraction Is Different

AI-based extraction doesn't rely on templates. Instead, it reads invoices the way a human would - by understanding context.

When you upload an invoice to an AI system, it:

  1. Reads the entire document
  2. Identifies what looks like a supplier name, date, total, line items, etc.
  3. Extracts the data based on meaning, not position

This means:

  • New suppliers work immediately - no setup required
  • Format changes don't matter - the AI adapts
  • Complex invoices are handled - multi-page, variable layouts, all fine

Real-World Accuracy

We're honest about accuracy. Our AI achieves:

  • 90%+ first-parse accuracy across all fields
  • 97% accuracy on amounts (the numbers that matter most)
  • Continuous improvement as the system learns your suppliers

That's not 100%, and we don't claim it is. You always review before posting to your accounting software. But it's accurate enough that a 30-second review is usually all you need.

The Learning Advantage

Here's where AI really shines: it learns.

Every time you correct a supplier name or adjust a field, the system remembers. Process 10 invoices from the same supplier, and by invoice 11, accuracy approaches 99%.

Template systems don't learn. They're static. AI systems get smarter with use.

Which Approach Is Right for You?

Template-based tools can work if:

  • You have few suppliers (< 20)
  • Those suppliers never change their invoice format
  • You have time to set up and maintain templates

AI extraction is better if:

  • You receive invoices from many suppliers
  • You don't want to maintain templates
  • You value time over configuration

Key Takeaways

  • Template-based invoice tools require setup for each supplier and break when formats change
  • AI extraction works with any format from day one, with no configuration
  • Real-world accuracy is 90%+ first-parse, improving as the system learns
  • For most businesses, AI saves significant time compared to templates
