Hi Benjamin,
Thank you for contacting WHMCS support. I see that you are having billing issues on your WHMCS install.
I checked the activity log and tried to review a random incorrect invoice (invoice #xxx, Client xx). It appears to be an Overage invoice. Overage invoices are scheduled to be generated at the last day of the month, for the bandwidth and disk over usage for the entire month. The product in the client account (xxxx) appears to be configured incorrectly as shown in the attached screenshot. As you can see in the screenshot, Overage Billing is enabled for the product and the limits are set to 0 for both Disk and Bandwidth. So the system generated the overage invoice for their current disk/bw usage as per the rates specified in the screenshot.
Please check all products (including this one) and disable overage billing to prevent any more such invoices.
Hope it helps. Do let us know if you need any further assistance.
Best regards,
