Eliminate B2B checkout friction, cart abandonment, and credit note spirals.

The Business Risk

The Checkout Abandonment and False Consumer Trap

Buyers frequently enter local tax numbers instead of international VAT formats, or make minor typos. Worse, national VIES gateways experience nightly downtime. Generic checkers misclassify these issues as invalid numbers, slapping 20 percent consumer VAT onto business orders.

  • Enterprise buyers abandon carts when unexpected domestic VAT is added to cross-border orders.
  • Procurement departments reject invoices with incorrect tax, requiring weeks of credit note processing.
  • Temporary government server downtime causes false rejections of legitimate enterprise accounts.
