Changes to the billing method or revenue method

This list shows when you can and cannot change the billing method or the revenue method:

• You can change a billing method of Milestone or Installment if milestones or installments do not exist.
• You can change a revenue method of Milestone, Installment, or Percentage of Completion if milestones, installments, or percentage of completions do not exist.
• You cannot change a transaction-based billing or revenue method, but you can create override milestones for the funding source.

  The override milestone is invoiced or recognized in addition to the transaction billing or revenue recognition. If you do not want to invoice or recognize revenue on the expense transactions, then you can put them on hold. You can invoice or recognize revenue only on the milestones.
