It is possible that sometimes sending an e-invoice is unsuccessful. In that case, you will receive a message from us about the delivery issue of the e-invoice. Such a message means two things:
first, the invoice has not been delivered to the recipient,
and secondly, in order to send the e-invoice successfully, it requires actions from you (as the invoice sender).
If you receive a message like this from us, it usually says what the problem is about. From this, you will know what to do to send the e-invoice successfully. Next, we will go through the most common errors in e-invoicing.
The e-invoice address does not link to a recipient
This is a common reason why e-invoice was not sent. Most often because the e-invoice address is incorrect. The invoice can only be delivered if the e-invoice address is completely correct. Any missing or extra character (i.e. extra space, number) in the e-invoice address prevents sending the invoice.
The correct e-invoice address can always be checked from the invoice recipient. They should have the latest information about the company's e-invoice address. Also, note that an e-invoice address may change over time, i.e. even if you have previously invoiced your customer using that e-invoice address, it doesn't guarantee that the address hasn't changed.
Another place where you can find an e-invoice address is here: www.verkkolaskuosoite.fi
If you found that the e-invoice address you used was incorrect, correct it on your customer's contact card so that future invoices would go to the correct address. Also fix the information in the invoice. This requires you to open the invoice and start modifying it. Now you can change the e-invoice address that you have previously used. Please note that simply changing the contact card information does not change the information of previously sent invoices.
Once the e-invoice information has been corrected, you can resend it.
The invoice due date has passed
In most cases, the e-invoice recipient's e-invoice operator rejects the invoice if it is missing a payment time. Make sure that the invoice has at least couple of business days payment time after e-invoice delivery, even if you have agreed with the recipient that the invoice will be paid immediately.
Invoice attachment is in invalid file format
Isolta's e-invoicing service supports most commonly used attachments. However, sometimes the recipients e-invoice operator is more selective in this matter, and the invoice is rejected due to a wrong attachment file format. In this case, the safest way is to use a PDF file format. It is generally valid for all operators.
