Your customer will receive a notification of a new bill from their bank (either in their online or mobile banking, or by email, or both).
When they log into their internet or mobile banking, they can view a bill summary in the Blink Bills section, which includes information like the biller, payment amount and due date. Clicking on a link in the bill summary will take them to a more detailed view of the bill that may also include a pdf version of the bill. The level of detailed information can be configured to suit your requirements.
