Accounting
The platform owner can create groups at each user level. These groups can be defined by currency, groups of countries (or states), and tax logic. Each group then becomes an individual accounting mechanism in its own right.
The platform is flexible enough to cater for multiple tax rate accountancy by country and by group (e.g. value added tax in the UK at 17.5%).
Similarly, cross currency selling across platform hierarchies presents no problem (e.g. if a distributor buys in £ sterling and sells on in $ US).
