hi, i'm trying to create a customer invoice approval workflow. i'm not exactly sure what i'm doing wrong as no invoices show up and no action shows up even the workflow is already created. any ideas?

Did you turn on the approval routing in Accounting Preferences?

yes i did!

need more info on the workflow - usually it is pretty straight forward process. Up on creation need to assign someone/role/group as approver to the button - are you doing that?

yes i am

Have you tried selecting the workflow state where the invoices are pending approval in the Action filter?
