Defined in:
lib/einvoicing/allowance_charge.rb

Overview

A document-level allowance (BG-20) or charge (BG-21).

The same shape covers both: whether it is deducted or added is decided by the array it sits in on the invoice (allowances: or charges:), so the amount itself is always expressed as a positive value.

Examples:

A 10% commercial discount on a 20% VAT base

Einvoicing::AllowanceCharge.new(
  amount:      BigDecimal("100.00"),
  vat_rate:    0.20,
  reason:      "Remise commerciale",
  reason_code: "95",
  base_amount: BigDecimal("1000.00"),
  percentage:  10
)
