LLM-native invoice processing

The AI invoice processor for
documents other tools can't handle.

45-page construction claims. 600-SKU manufacturing orders. Invoices up to 1,000 pages with business logic that changes by vendor. Teach Cretac once — like training an employee — and it applies your exact rules forever. No templates. No rules that break. 100% accuracy.

Free to start. Self-hostable. Up to 1,000 pages per document.

Other tools claim 99%. Then your vendor changes their layout.

Traditional tools extract data by matching pixel positions on a template. They call it "99% accurate" — until the vendor redesigns their invoice, or sends a 45-page document, or uses unusual business logic. Then accuracy drops silently and your team catches it weeks later.

Template-based tools
  • Complex multi-page invoices require manual splitting
  • The AI never learns — you configure the same rules forever
  • "99% accuracy" based on rigid pixel-position extraction
  • One layout change and accuracy drops silently
With Cretac — LLM-native
  • Handles any complexity — up to 1,000 pages, custom logic per vendor
  • Teach it once, like an employee — it remembers forever
  • 100% accuracy — LLM reads the document, not a template
  • Every correction makes the system permanently smarter

Like training an employee who never forgets

Tell Cretac how to process an invoice once — in plain language — and it remembers forever. Your rules are locked to each vendor's real identity, not a fragile pixel template. The next time that vendor sends an invoice, even a 1,000-page one, your exact logic is applied automatically.

Step 1

Teach it your rules

Upload a document and explain how you want it processed — conditional tax handling, cost allocations, vendor-specific mappings, custom calculations. Plain language. No code. No template builders.

Step 2

It remembers permanently

Your rules are saved against the vendor's real identity — ABN, bank account, email domain — not a pixel template. The vendor redesigns their invoice? Doesn't matter. The rules still apply.

Step 3

Never configure it again

Next time that vendor sends an invoice — even a 1,000-page one — your exact business logic is applied automatically. Correct something? It learns permanently. That's how you reach 100%.

Built for invoices other tools give up on

Handle any complexity, teach it once like an employee, and get 100% accuracy — not from rigid templates, but from a new generation of AI that actually reads and understands your documents.

Core

Any Complexity, Up to 1,000 Pages

45-page construction claims. Hospital invoices with 450+ line items. Manufacturing orders spanning 600 SKUs. Custom business logic per vendor — tax handling, cost allocations, approval routing. Up to 3,000 pages with enterprise configuration.

Core

Teach Once, Never Configure Again

Like training an employee: explain your rules in plain language and the AI remembers them permanently. Rules are locked to the vendor's real identity — not a pixel template. No ongoing maintenance.

Core

100% Accurate, Not 99%

Not template-based pixel extraction that claims 99%. A new generation of AI that reads and understands documents. Every correction is permanent — the same mistake never happens twice. Accuracy converges to 100%.

LLM-Native, Not OCR

Built on frontier language models from the ground up. Handles table-dense layouts, handwritten notes, multi-currency line items, and low-resolution scans. The AI reads your document like a human would.

Human Review & Learning Loop

Review AI-extracted data side-by-side with the original. Approve, correct, or route for review. Every correction feeds back into the memory system permanently — the system only gets smarter.

Self-Hostable & Enterprise-Secure

Deploy on your own infrastructure or use our hosted service. Google OAuth SSO, encrypted storage, role-based access, and multi-tenant isolation. Your financial data never has to leave your control.

Complex invoices, handled.
Teach once, done forever.

From 45-page construction claims to 600-SKU manufacturing orders — teach Cretac your business logic once and it applies it precisely, at scale, forever. Not 99%. 100%.
