To be able to send an e-invoice successfully, a number of elements are mandatory in the invoice. In the tradeinterop portal, these fields are marked with a red '*'.
In general, you have to fill in the following fields:
- Select your customer in the field 'Select customer'. (please note: do NOT enter your own company name here)
- Invoice number: use your own invoice number
- Invoice date
NOTE: In addition to the above fields, many of your customers also want to receive an order number or cost centre. This can be entered in the portal under Customer order number: enter the number exactly as you received it from your customer, without text. So: '10056' and NOT 'order number 10056'.
Furthermore, the following elements are mandatory on the lines:
- Article number: if applicable. If you do not use an item number, you can fill in '1'.
- Number of items
- Unit number
- Unit Price
