Requirement 5. Which type of billing system is fairer to clients? Explain.
The
▼
ABC
traditional
billing system should be fairer to clients because they are charged according to
▼
the direct labour hours on the job
the resources they used
the total hours on the job
.
For example, copying blueprints is
▼
not expensive
very expensive
. Under the fairer system, clients are charged
▼
a set one time fee for
according to the number of
blueprint copies that their job required. The fairer system better recognized the extent to which
▼
operating

selling
costs are incurred by each unique client job.
