You can either send your e-bills from your financial software or use the e-bill light online solution:

Integrated e-bill solution

Our integrated solution is ideal if you already have your own software and want to optimize payment collection. Issue your invoices in your software as usual. The invoice data is transferred to PostFinance from your system as a data file before being processed and forwarded to the recipient automatically in electronic format.

eInvoicing portal

You can send and receive invoices electronically via the eInvoicing portal, and manage your data and settings for e-bill yourself. New e-bill customers can register for the service directly online.

E-bill light

E-bill light is ideal if you only send a few invoices each year and do not have your own software. Registration and invoice recording are done online.

The price level depends on the number of e-bills sent/received per customer and per month.
