You can check whether your invoice has been sent in the following way:
Click in the left menu on 'Invoices' -> 'Outgoing invoices'. This overview contains all invoices that were created and/or sent by you.
At the end of the line of each invoice you can see the status. You can also press the 'view' button to open the sent invoices here to view them.
'Aangemaakt' or 'Created' status
Does the status show that your invoice is 'Aangemaakt' or 'Created'? This means that your invoice has been created, but has not yet been sent.
You can send your invoice as follows:
Click on 'Bewerk' or 'Edit' at the end of the line for the correct invoice. You now see the details of the invoice. When the invoice is correct, scroll down. Click on the button 'Verstuur factuur' or 'Send invoice' to send your invoice. The sent invoice can then be found under 'Uitgaande facturen' or 'Outgoing invoices'.
'Bevestigd' or 'Confirmed' status
When your invoice is received by the recipient, the status in the portal changes to 'Bevestigd' or 'Confirmed'.
