After starting "Web Billing," you can download the billing breakdowns for the past four months maximum including this month as DF or CSV formats (CSV data extension is "txt").

However, the limit for downloading is up to 1,000 lines. Smart phones / mobile phones (feature phones) are not available for downloading.

In addition, you can print out a payment certificate for the past 15 months maximum (usage fee statement for the customers who pay with credit card).
