To launch your product line you'll need to purchase samples, design your product & packaging, and stock inventory. These costs are dependent on what you are creating and can vary from supplier to supplier.
There are always ways in which you as a creator can work with your supplier to cut costs. For example, working with an international supplier may provide for lower production costs than one based in the United States. Choosing to have your inventory shipped via sea travel as opposed to air travel can also help to lower your costs.
Pietra always recommends discussing budget and timelines with your suppliers as early as possible, so that proper expectations are set.
