It is a gig offered for a small to medium businesses ( and may be large companies) : A Cost Allocation Report,
i.e. Allocating Indirect costs over the Production cost centers.
I work as an Accountant in a large company and make this kind of reports (experience over 4 years) , so I found it very useful to make a Win-Win deal and make money here and at the same time increase my experience,
The final result ( in Excel or PDF ) would contain a report for each cost center include Revenues , direct cost and Indirect cost the Net Profit/Loss.
