What's a billing currency type?

The type of currency in which you issue invoices to the Bill-to Account on a contract bill plan, generate revenue, and transfer revenue to Oracle Fusion General Ledger as entered currency. Valid values are Bill Transaction, Contract, and User.

For rate-based bill plans, bill transaction currency is either currency of the bill rate schedule or cost transaction currency of the expenditure item, depending on whether bill rates or markups are used. For fixed price bill plans, billing currency type must be either Contract or User.

A user-defined billing currency type indicates that you, as a user can specify the particular single currency in which invoices are issued and revenue is generated.
