What preparations should I make to apply for a handbag merchandiser?

I'm also a handbag man, and I'm a merchandiser. At the very least, you should know the calculation method of main materials and materials. For example, this list should tell the purchaser how many main materials to buy, how much materials to pay, hardware and the like, how many cartons to pack large pieces, and how many lines to buy to come back to the workshop to make goods. This is the most basic thing. I also follow up the production progress and report to the business or your superior leader every day. "You should distinguish between production and business."
