AI Training & Retrieval (private model + vector DB RAG)
Here’s the big difference between a generic AI chat tool like ChatGPT and TaxLayer’s AI:
Most AI tools (like ChatGPT) are generalists. They know a little about everything — but not enough about Greek tax law or myDATA. Ask them a compliance question, and they often guess, confuse rules, or miss updates.
TaxLayer’s AI is different. It’s a specialist, built with:
Fine-tuned training on myDATA rules and error codes
RAG (Retrieval-Augmented Generation) that looks up the latest AADE regulations in real time
A private knowledge base that includes your vendors, clients, and history
🔑 What That Means for You
📖 Always Up-to-Date The AI checks against the latest AADE rules. If VAT rates or exemption codes change, you’ll know today — not months later.
🎯 Pinpoint Accuracy No vague guesses. It fetches the exact article, rule, and error code — and tells you how it applies to your invoice.
🔒 Private by Design Your data is stored in a private vector database. It’s used only to answer your questions — never for training, never shared with other firms.
🧠 Context-Aware The AI doesn’t just parrot the law. It looks at your documents and gives a fix that works for your specific client, vendor, and transaction.
📊 Accuracy in Numbers
Generic AI (ChatGPT, untrained): ~55–60% accuracy on myDATA queries
TaxLayer AI (Fine-tuned + RAG): 95–99% accuracy with rule citations
Citation Precision: 98% of answers include the correct AADE reference
Response Time: <3 seconds on average
✅ Real-World Impact
❌ Ask a generic AI: “Why is this invoice rejected?” → You might get: “VAT errors are common; check your rates.”
✅ Ask TaxLayer AI: “Invoice INV-2024-1234 fails myDATA rule 3.2.1 for intra-EU sales. Change VAT category to 6 and add exemption code 1. Then revalidate.”
🔎 Pain point solved: Instead of chasing vague advice, you get concrete, regulation-backed instructions you can act on immediately — and show in an audit if needed.
📖 Story: Maria at Month-End Close
Maria, an accountant in Athens, uploads 200 invoices at month-end. Her dashboard shows 15 errors — mostly VAT mismatches.
She opens AI Chat and asks: 👉 “Why did these invoices fail?”
The AI scans the invoices + AADE rules
Finds that 12 are intra-EU services misclassified as domestic
Explains: “Apply VAT category 6 with exemption code 1 per rule 3.2.1.”
Suggests a bulk fix to correct all 12 in one click
In less than 2 minutes, Maria has cleared what would have taken her half a day of manual checking. At submission time, her error count is zero — and she closes the month with confidence.
👉 In short: RAG makes your AI as sharp as a tax expert who has memorized every AADE rule and your firm’s history.
