Manual E-bill 499.41

6.3 Signature check
In order to adhere to legal regulations, it is particularly important to ensure
that the bill recipient checks the signature and logs the result before the bill
is used.
Article 3 ElDI-V paragraph 1 states:
The conditions for proof of electronic data required by article 43, paragraph
1 of the MWSTGV are fulfilled if:
Section c “the electronic data are checked and verified for integrity, authenticity
and signature authorization by means of the digital signature
after the completed transmission but before use at the latest
and the result is documented.”
The transmission is deemed to be completed as soon as the digital signed
bills are available for the bill recipient (in the inbox) or when the transmission
has been completed successfully (delivery channel AS2). “Use” is
considered to mean specifically the use of the data as an accounting slip.
Unless otherwise instructed, before delivering the data PostFinance checks
the signature and delivers the results along with the bill data.
Authorized persons (e. g. auditors, judges, etc.) can also check individual
bills directly online at w ww.postfinance.ch/e-bill.
6.4 Bill processing
The downloaded bill data can be scanned into the bill recipient’s ERP system
for further processing, such as account assignment, approval, booking and
storage. Finally, a payment order using existing payment methods (e. g. EPO)
can be generated using the finance software.
6.5 Archiving digitally signed bills
In accordance with legal requirements (in particular the MWSTG, GeBüV,
etc.) billers are responsible for their own bill storage and further corresponding
data (see section 1.4). Billers acknowledge that invoice details in
particular will not be archived by PostFinance.
