SIX - Easy digital payment of bills thanks to eBill

By opening up the eBill market, SIX has created a solution with which even more invoices can be paid digitally in the future.

June, 2020

By merging the two «e-bill systems» of PostFinance and SIX Paynet AG into a central e-bill platform for all banks, many synergies can be exploited. This merger also involved a re-branding of the old term «e-bill» to «eBill».

The opening of the market for so-called network partners enables additional billers (from village associations to telecom providers) to deliver their bills digitally. The network partners form the interface between the biller and SIX.

The continuous further development of eBill ensures that the product is future-proof. For example, it is possible to easily create an eBill from a QR invoice.


Although e-bill was a successful product, it was operated in parallel by two companies. As a result, and because of the close coupling of the existing SIX system with the banks, market development had come to a standstill in recent years.
These were three of the biggest challenges facing SIX:

  1. There were two e-bill systems for the end customer area with many different formats and specialities.

  2. Innovations and further development in the existing SIX system were difficult to achieve. On the one hand, the existing system was getting on in years, and on the other hand there was a very close link to the banks.

  3. New digital solutions would exert increasing pressure in the future, as is already the case in the banking world through FinTechs in many areas.


If the SIX and the Swiss financial centre had ignored the above-mentioned challenges, this would have led to the following consequences:

  1. Market development would have continued to stagnate because it would have been difficult for new partners to enter the market. Operating two almost identical solutions would have led to ever higher costs.

  2. It would not have been possible to react to the market stagnation, as product innovation would hardly have been possible.

  3. The risk of being overtaken by new, open digitisation solutions would have increased. This would ultimately have led to a loss of customers.

«For the development of the eBill platform, we have found a partner in ipt who, in addition to their love of the craft, shares with us a high understanding of values based on openness and transparency, helpfulness, appreciation and feedback.»
Philipp Huber SIX


The new eBill platform offers a standardized solution for electronic invoices in the Swiss financial center. ipt has supported SIX in creating a solution that works with the latest technologies and is constantly being improved and developed.
Thanks to a simple format and well-defined interfaces, the many stakeholders can be easily connected to the platform.

  1. Simple usability

  2. Saving costs and resources

    There are no shipping costs and nature is spared by the digital transmission.

  3. Transaction based accounting

«The eBill platform is a one-of-a-kind solution, unique in the world as is the team that developed the solution. It is said that a solution reflects the organization or the team behind it. I could not be happier with both.»
