The future e-billing role model from PostFinance

Changes from April 2019

What is changing? Why? Who is affected? Technical impact on customers
What is changing?

Connection of PostFinance as a network partner (NWP) to the new SIX eBill infrastructure.

PostFinance will register the affected invoice issuers with eBill with effect from November.

E-bills intended for e-banking customers connected to the new SIX eBill portal will be delivered to the SIX eBill infrastructure via the new network partner interface.
Who is affected?
Invoice issuers who send e-bills to e-finance/banking customers via us.
Technical impact on customers
No technical modifications are required.
PostFinance will migrate its invoice issuers to the eBill portal with effect from November to ensure that everything runs smoothly.

Please note: with PostFinance as your network partner, you will be able to reach all customers, including e-banking customers, without additional costs from November (no technical modifications are required here, either).
What is changing?
There will now be primary and secondary network partners (NWP).
With the advent of the eBill platform, the new role of network partner has been created. Previously, there were two providers; in future, multiple network partners will be possible.
Who is affected?
All invoice issuers, as they have to decide on a primary network partner.
Technical impact on customers
From spring 2020, all information on registrations and cancellations of your invoice recipients – regardless of which financial institution they are with – will only be supplied via one network partner. This means that registration and cancellation data can only be received via this primary network partner. Invoice issuers that send electronic invoices via multiple network partners must therefore choose a primary network partner by the spring of 2020 at the latest.

If you would like to have PostFinance as your primary network partner, you can notify us of this in writing by e-mailing PostFinance e-bill.
What is changing?
The new unit prices for incoming and outgoing deliveries will take effect from 1 November 2019.
Due to PostFinance’s connection to eBill as a network partner, we are adapting our pricing model for e-bills.
Who is affected?
All e-bill issuers are affected: the price level now depends on the number of e-bills supplied/received per customer and per month. In future, there will no longer be any costs for additional services, such as payment of Interconnect or registration fees.

You can find the new prices on the page E-bill for invoice issuers.
Technical impact on customers
What is changing?
Return of the signed archive file

Return of archive files is being discontinued. First of all, returns to recipients will no longer be possible with new delivery methods. This currently affects all e-bills that are delivered as a hybrid bill (PDF with integrated user data, ZUGFeRD) and all e-bills that are delivered to the new SIX eBill infrastructure via the network partner interface.

OEIDI repealed as of 1 January 2018
There are no longer any requirements for keeping signed e-bills. The invoice issuer can archive their invoice data in the same way as invoice data sent on other channels.

Who is affected?
Invoice issuers who process your e-bills with a signature.
Technical impact on customers

If the process explicitly requires the archive file, this must be changed in advance.
Generally speaking, we advise invoice issuers against downloading the signed archive file from now on.

  • Connecting e-finance to the new SIX eBill portal

    According to the current roadmap, e-bill customers who receive e-bills via e-finance will be transferred to the new SIX eBill portal in the second quarter of 2020. From this point onwards, all e-bills intended for e-finance and e-banking customers will be delivered to the SIX eBill infrastructure via the new network partner interface.

    New web services

    We have offered improved B2B services since 2016. These are based on new technology and provide numerous benefits in relation to previous B2B web services. Given that needs are changing and security requirements are becoming stricter, the old B2B web services no longer meet the current security standard. This is why we recommend that all software companies still using the old B2B web services should migrate to the new B2B services with the next release. You can find more information in the e-bill manual.

  • Name and brand of the Swiss financial center’s new infrastructure for e-bills sent to e-banking customers. eBill also refers to the new portal where e-banking customers will process their e-bills in future. eBill is the successor to e-bill. The e-bill function in e-finance will therefore also be renamed eBill in future.
