I have a project.
Project is based off a paid invoice.
The paid invoice has an expense.
When I am creating an invoice I should be able to send to/create a new project. Then I should be able to link an expense to that invoice.
When I look at my project I want to be able to click the invoice it was generated from with and the expense that I need to pay out.
I recently had to manually work out which timesheet entries related to which invoices because there is no proper linking. This took ages and is completely unnecessary.
