Our AI compares the company name on your invoice with the official name registered in the EU VAT database. If there's a mismatch, the system flags it as a potential fraud risk and provides a severity rating. Exact matches show no risk, similar names show medium risk (common for abbreviations), and complete mismatches indicate high fraud risk.
