  The use of the Internet has become an urgent necessity in various fields and
activities. One of such important fields could be electronic business
(E-Business). E-business includes all operations and activities related to
Internet commerce, including e-commerce, e-marketing, eservices, e-payment, and
electronic transfer. This proposal focuses on two perspectives that are under
e-commerce umbrella where many e-payment process models suffer from the lack of
clarity in the special procedures of the verification of the quality of
services. This proposal, therefore, proposes a new E-payment process model to
enhance the quality of service through maintaining availability. The proposed
model focuses on the concepts of electronic payment model dimensions, which
includes integrity, non-repudiation, authenticity, confidentiality, privacy,
and availability. Accordingly, the proposed model implements the availability
dimension in order to improve the quality of services that are provided to the
consumer.
