Redeemed Vouchers as Prepayment
Vouchers redeemed as a means of payment are treated as a prepaid amount (BT-113) – not as a discount. VAT is calculated on the full amount; the voucher merely reduces the amount due for payment (BT-115).
<ram:SpecifiedTradeSettlementHeaderMonetarySummation>
<ram:GrandTotalAmount>100.00</ram:GrandTotalAmount>
<ram:TotalPrepaidAmount>25.00</ram:TotalPrepaidAmount> <!-- BT-113 -->
<ram:DuePayableAmount>75.00</ram:DuePayableAmount> <!-- BT-115 -->
</ram:SpecifiedTradeSettlementHeaderMonetarySummation>
Why not a price reduction? A voucher is prepaid value, not a price reduction. EN 16931 requires it to be represented as BT-113. If the voucher were represented as an allowance, the VAT basis would be incorrect.
You enable the processing of Aheadworks vouchers under Third-Party Integrations. You connect your own voucher/credit modules via the PrepaidAdapterInterface – see Developers.
Purchased Multipurpose Vouchers
Vouchers purchased as a product (multipurpose vouchers, product types aw_giftcard, giftcard) receive their own VAT treatment. Multipurpose vouchers are usually VAT-free at purchase; VAT arises only upon redemption.
You configure the VAT category and the exemption reason (BT-120) for purchased vouchers under Third-Party Integrations:
| Setting | Meaning |
|---|---|
| VAT category for vouchers | VAT treatment of purchased vouchers (default E, often also O). |
| Exemption Reason (BT-120) | Exemption reason, e.g. "Multipurpose Voucher". Mandatory for categories E and O. |
The two cases must be clearly separated: redemption = prepaid amount (BT-113); purchase of a multipurpose voucher = VAT-free line with its own category and exemption reason.
