Hi,
I have more than 9 years of experience in software development and designs. I have worked on various industry level Desktop and Web applications.
As I understood, you need an inventory Management System for your warehouse. Where you can maintain Incoming and Outgoing stock. You also want some reports around the same including. Total stock available in warehouse with item wise and cumulative cost of the same stock.
I can pick this task and Desktop Application looks more feasible for this task.
Looking forward to work with you on the same.
