Validate Tax Status at Signup—Before the First Transaction
Stop revenue leakage and compliance errors by validating customer Tax IDs during account creation, not checkout.
The Signup Validation Gap
Most platforms validate Tax IDs at checkout, causing friction and cart abandonment. Worse, invalid Tax IDs mean incorrect tax charges and compliance violations from day one.
The Signup Flow

B2B customer creates account and enters business Tax ID
Real-Time Check
Lookuptax validates Tax ID against government database
Profile Enrichment
Auto-populate business name, address, VAT status
Frictionless Checkout
Future transactions use verified tax data—no re-validation needed
Signup Optimization Features
