Manual E-bill 499.41

8. Bill presentment module
If the bill presentment module is used (see section 4.3.1) there are two
possible options:
• The biller creates a PDF file for each bill from the bill detail data and
transmits these to PostFinance (see section 8.1).
• PostFinance creates a PDF for each submitted bill data using a standard
style sheet (see section 8.2).
There is always a 1:1 relationship between the bill data and the bill details.
To show the same bill detail for several bills, the static bill detail must be
used (see section 4.3.4).
8.1 Delivery of bill details by the biller
The biller can design the layout of the PDF files as he wishes. In accordance
with the security requirements of e-finance, they may not contain any hyperlinks
except a secure link (URL in the format https:/ /w ww.yourcompany.
ch/...) to a bill enclosure located on the biller’s own platform. Furthermore,
no active elements, e. g. Java Script, ActiveX or other links may be contained
in them.
To ensure optimum performance for the bill recipient, PostFinance recommends
that the individual PDF files should not exceed 50 KB. The maximum
size is 150 KB in order to avoid transmission problems.
PDF files are assigned to the bill data via the BillerID and the TransactionID
which together form a unique bill identifier. Thus the naming convention
for PDF files is as follows:
_.PDF
Because PostFinance cannot check whether the details in the bill data
correspond to those of the PDF file, it is the biller’s responsibility to ensure
the correctness of the PDF file and to adhere to this naming convention.
The PDF files may be delivered separately or they may be integrated
as a referenced object as a Base64 string with MimeType=x-application/
pdfappendix into the “Appendix” element in the yellowbill invoice.
If the PDF files are delivered separately, the order in which they are delivered
makes no difference. Ideally, however, all bills and their corresponding
PDF files should be delivered on the same day. For further details concerning
data delivery, please refer to section 11.
8.2 Generating bill details via PostFinance
The bill details in the yellowbill system are created exclusively by means
of a standard style sheet. They contain the information required by law
(incl. the addresses of the biller and bill recipient, VAT number of the biller,
bill items, summary for each VAT set, etc.) but do not include the biller’s
logo. It is not possible to make individual adjustments to the style sheet.
