Manufacturing billing software
Raw, finished, and job work on the same books. A challan when goods move. Sales tax on the invoice.

Job work
Job work in and job work out. A batch stays on the material.
Movement
A delivery challan and a gate pass when goods leave.
Warehouses
Raw and finished can sit in different rooms.
Sales tax
The invoice carries the tax. Goods stay the company’s until paid, if that is the footer you set.
