There are different methods for invoicing and these can be set up in the default settings. Every organization has its own default settings.
Define settings according to the needs of your organization:
Go to Settings -> Your company information -> Module specific rights - Projects
- The default status of a new project. Would you like to have it set as "offered" or "ongoing" ?
- Invoicing methods for an on going project. For example, invoice hours, expenses and bills.
