- Automatic and electronic processing for small and large invoice volumes
- Higher delivery rate and quicker payment receipt
- No printing and shipping costs
- Better data quality of incoming payment information

- Different invoicing methods

With B2B e-invoicing, you send your accounts receivable invoices directly from your ERP (software) or via our eInvoicing portal. This will allow you to send invoices to business customers quickly, easily and completely electronically.

Step 1: Check your software’s interface

Check whether your ERP has an interface to PostFinance.

To the software check

If your ERP has an interface, you can create your accounts receivable invoices following onboarding as usual and send us your invoice data as a file directly from your system.

Does your ERP not yet have an interface to PostFinance, or do you not work with an ERP? In our eInvoicing portal, you can upload your PDF invoices individually and have them sent electronically as B2B e-invoices. This is ideal if you send only a small number of digital invoices.

Step 2: Create a login for the eInvoicing portal

Create a login for our eInvoicing portal so that you can send your invoices securely from your ERP or from the eInvoicing portal. You can create your login yourself directly online. We would be happy to help if you have any questions.

Sending and receiving B2B e-invoices via Interconnect (PDF) The link will open in a new window

An e-invoice is issued, sent and received in a predefined, structured electronic format (e.g. XML). In this way, invoices can be processed completely automatically and electronically from ERP to ERP or transferred digitally via an invoice portal. PostFinance offers e-invoices with the B2B e-invoicing product.

Using B2B e-invoices, you will benefit from the advantages of standardization and automation. You save on time and costs. You do not have to manually enter invoice data, and you can view all invoices to be issued in the digital archive at any time. Payment transactions are carried out using existing processes, and it is very easy to track all actions thanks to electronic storage.

Useful information: PostFinance also provides a solution for paper invoices: with Paper Bill, we will take care of printing and mailing for you and optimize processing of your returns. Practical: for you, this runs via the same interface as B2B e-invoicing and eBill.

Ideally, you should have an ERP you can use to create your invoices, which you can then send to PostFinance via an interface. Alternatively, you can use our eInvoicing portal to send invoices. You can upload your PDF invoices individually to send them electronically as B2B e-invoices or eBills. Or you can enter the invoices manually. This is ideal if you send only a small number of digital invoices.

With B2B e-invoices, you can connect not only with PostFinance customers, but also customers from other partners. PostFinance offers a large network with numerous software and Interconnect partners, allowing excellent connectivity for B2B e-invoicing in Switzerland and worldwide.
