You can define billing rates in three places:

  • Account

  • TT User

  • Project

When creating invoices, you need to decide which of these rates should be used for billing. Once you’ve chosen the object, update the invoice-header-summarize-by string in the TimeTracker Flags to reflect your choice.


More information on adding the details to the flag is given here.


This ensures that the invoice calculations always pick the correct billing rate.
