I added a bill-item company name path in bill-route.ts.
I added a months drop-down-list in bill-item page
took out the buttons (edit and delete).created a new button paid.
Did you remove the logic for loadByCompanyName() in src/main/webapp/app/entities/bill-item/bill-item.component.ts so Chai can add it in the back end? I see the method signature there so I wasn't sure.
