Welcome & Getting Started

Welcome to TaxLayer, your all-in-one platform for automating myDATA compliance and managing financial documents with the help of AI-powered validation.

🧾 What is TaxLayer?

TaxLayer is a compliance and finance automation platform for myData. It streamlines e-invoicing, document processing, and myDATA submissions by combining:

  • AI-powered extraction (Greek & English)

  • Automated compliance validation (myDATA-aware)

  • Customisable workflows (from quick checks to full automation)

Outcome: fewer rejections, faster close, clearer audit trails.


👥 Who is it for?

  • Accounting firms — manage multiple clients, reduce manual entry, prevent myDATA rejections.

  • Businesses (in-house finance) — automate invoice checks & submissions without changing your ERP overnight.

  • Compliance teams — monitor validation health, submissions, and evidence from a single place.

Pain point solved: No more guessing “why did myData reject this?” — TaxLayer explains issues in plain language and suggests fixes.


✅ What you’ll accomplish today (5–7 minutes)

  • Create your first client

  • Upload & validate your first invoice

  • (Optional) Submit to myDATA (or test in Sandbox first)
