Tax settings

For tax settings, by default tax is included in the price. You'll need to set a default tax rate in percentage (ex: 13). If items have a tax value, as some products may have different tax (VAT usually), it overides the default value.

  • Tax Exclusive means tax is applied on top of the unit price.
  • Tax Inclusive means the unit price includes tax.

When using the normal keypad PoS, the default tax value is used, and tax value is always included in the value.
