How do i create a new status?

Would like to create a custom status for invoices? any ideas, much appreciated.

Thank you

Status types are simple numbers which are pre-defined in the application. But to add a new one you would have to change the process defined in the invoice module and add it to the selection array.
It’s not recommended if you are not familiar with the system as you can break a lot of stuff.

Thanks @Kovah i figured it out how to do it. Thank you Lee.
