Displaying a discount on the invoice

There is no dedicated discount field in the invoice request. A discount is represented as a separate line item with a negative amount:

  • Add a new <tetel> element and put the name or title of the discount in <megnevezes>.
  • Set the net unit price (<nettoEgysegar>) to a negative value; the quantity (<mennyiseg>) stays positive. This makes the net, VAT and gross values of the line negative as well.
  • Use the same VAT rate (<afakulcs>) as the item the discount applies to.
  • If the discount belongs to a specific item, place the discount line directly after that item so it is clear on the invoice which product or service it belongs to.

Example discount item (a 2 000 HUF net discount on a 27% VAT item):

<tetel>
    <megnevezes>Kedvezmény: Minta termék</megnevezes>
    <mennyiseg>1.0</mennyiseg>
    <mennyisegiEgyseg>db</mennyisegiEgyseg>
    <nettoEgysegar>-2000</nettoEgysegar>
    <afakulcs>27</afakulcs>
    <nettoErtek>-2000.0</nettoErtek>
    <afaErtek>-540.0</afaErtek>
    <bruttoErtek>-2540.0</bruttoErtek>
</tetel>
No percentage or invoice-total discount

There is no percentage-based or invoice-total discount function in Számlázz.hu. Calculate the discount amount in your own system and send it as a negative line item as shown above.

The usual item amount checks apply to negative lines too: <nettoErtek> = <nettoEgysegar> × <mennyiseg>, <afaErtek> = <nettoErtek> × <afakulcs> / 100, <bruttoErtek> = <nettoErtek> + <afaErtek>. See Basics / Error handling & error codes (codes 259–264).
