In some rare situations documents (invoices, receipts, proformas, notices) do not appear correctly on some versions of the Mac OS – more specifically, characters are missing.

This happens only when a document is opened with Mac Preview – the problem does not appear on any other reader and on any other operating system.

In these cases, please download a free PDF reader from the Internet (a reader is a program for viewing documents in PDF format). For MacOS there are the following alternatives: Adobe Reader Skim or PDF View.

Using the alternate reader, you will be able to view without any problems any document issued through online-billing-service.com.
