How can billable costs be re-allocated to a particular project?

Hi preryjka, thanks for joining us here on the Community 

Once you have enabled billable expenses you can assign this to a project on the 'category details' or 'item details' line of the bill/expense by ticking the 'billable' column and selecting the project under 'customer/project'. 

Please get back to us below if you have any Q's. 🙂
