Sending and receiving e-invoices

With Isolta, you can send and receive all your invoices as e-invoices. By sending your invoices as e-invoices, you can be more sure that you will receive the money for your products or services. You speed up the processing of purchase invoices by receiving them as e-invoices and paying for them using either a QR code or a virtual barcode.

Invoice journey to your customer


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.

Receiving e-invoices

As an Isolta’s user, you can receive e-invoices directly through the e-invoice operator (Apix) to your Isolta account. In order to receive e-invoices, you need to provide your supplier with your e-invoice address and operator code, which you will find from your Isolta account. Once you receive an e-invoice, you can pay it by reading either scanning a QR code or a virtual barcode from the invoice. The service does not yet have an actual bank connection for payment. However, bank connection feature can be found in the Procountor Solo service, which is built based on Isolta. Learn more about Solo.
