VAT Validation & Calculation

Pricelist Heaven handles VAT calculation and validation for EU businesses.

VAT Calculation

The system automatically converts prices between VAT-inclusive and VAT-exclusive based on your configuration.

Example:

  • Supplier price: €121 (incl. 21% VAT)
  • Odoo expects: VAT-exclusive
  • Result: €100 (excl. VAT)

VIES Validation

For EU customers, validate VAT numbers via the VIES system:

  1. Enter customer VAT number
  2. System queries EU VIES database
  3. Result: Valid or Invalid

VAT Rules

  • NL without VAT: 21% Dutch VAT charged
  • EU with valid VAT: 0% (reverse charge)
  • EU without valid VAT: 21% Dutch VAT charged
  • Outside EU: 0% (export)

Configuration

Settings → VAT Configuration

  • Supplier prices include VAT: Yes/No
  • Odoo prices include VAT: Yes/No
  • Default VAT rate: 21% (or your rate)

The system handles all conversions automatically.
