There are three ways to send an invoice electronically: e-invoice, email, or printing service.
1. An invoice sent as an e-invoice will be forwarded by our partner Apix to your customer's e-invoice operator. Then the e-invoice operator delivers the invoice to your customer. Usually, an invoice received as an e-invoice goes to be read directly into the recipient's invoice or accounting software.
2. If you send he invoice via email, your customer will receive an email from where they can open the invoice by clicking the link on the email. The invoice can be downloaded as a PDF file or printed. The invoice itself is therefore not directly attached to the email but behind a separate link. This allows you to track whether your customer has opened the invoice or not, from Show invoice events inside your Isolta account. Read more about email invoicing on our support page.
3. An invoice sent through the printing service will be printed, put in an envelope and mailed on your behalf. Apix's partner handles the printing and putting it into an envelope, but the Post will eventually deliver the invoice. Delivery time is about 4 working days.
