There are two components to e-invoicing billing:

1. Annual subscription to MessageXchange's e-invoicing Access Point ($50)

This is a yearly subscription which allows you to access the e-invoicing service. It covers maintenance of the MessageXchange Access Point, your eInvoicing service and your access to the portal.


2. Credits ($50 for 1,000 credits)

Credits are charged at $50 for 1,000 credits. 1 credit is 1mb, or part thereof, of data.

For your reference, and this is a guide only:

  • an average e-invoice with one line item is about 5kb
  • an average e-invoice with two line items is about 6kb
  • an average e-invoice with ten line items is about 15kb

Here are some scenarios:

  1. You send an e-invoice that's 12kb. This will consume 1 credit.
  2. You receive an e-invoice that's 12kb with an attachment that's 500kb. This will consume 1 credit.
  3. You receive an e-invoice that's 12kb with an attachment that's 1.1MB. This will consume 2 credits.

We count the attachments in the UBL message that we exchange through the Peppol network. This means we calculate the size of the attachment when it's Base64 encoded, so this may be slightly different to the size of the attachment you see on your computer.
