    <salesInvoiceAmount iso4217currencyCode="USD" currencyRate="1.0">6445,75</salesInvoiceAmount>
    <salesInvoiceStatus type="netvisor">open</salesInvoiceStatus>
    <salesInvoiceDueDate format="ansi">2022-08-06</salesInvoiceDueDate>
    <salesInvoiceDeliveryDate format="ansi">2022-08-06</salesInvoiceDeliveryDate>
    <invoicingCustomeridentifier type="customer">3</invoicingCustomeridentifier>
    <invoiceLines>
      <invoiceLine>
        <salesInvoiceProductLine>
          <productIdentifier type="customer">1</productIdentifier>
          <productName>Basketball</productName>
          <productunitPrice type="net">123,0</productunitPrice>
          <productVatPercentage vatcode="KOMY">24</productVatPercentage>
          <salesInvoiceProductLineQuantity>25</salesInvoiceProductLineQuantity>
        </salesInvoiceProductLine>
      </invoiceLine>
      <invoiceLine>
        <salesInvoiceProductLine>
          <productIdentifier type="customer">1</productIdentifier>
          <productName>Football</productName>
          <productunitPrice type="net">110,0</productunitPrice>
          <productVatPercentage vatcode="KOMY">24</productVatPercentage>
          <salesInvoiceProductLineQuantity>23</salesInvoiceProductLineQuantity>
        </salesInvoiceProductLine>
      </invoiceLine>
    </invoiceLines>
  </salesInvoice>
</root>
