You can view your invoice by logging in at the link below. There you can also see in detail what the costs are.

Here you will get help with deciphering what the invoice shows.

A bit unclear to me if you have Autogiro or E-invoice at the moment.Since you mention that you do not receive an invoice

But here you have links to be able to apply for it, so you avoid the invoice cost of SEK 49/per month.

Hope this will help you with your question. ( The links are only in Swedish. But maybee can use a translator for help.
