How do I make a physical product distribution plan/package?

Hi
The best method in which to learn how to manage your relationship with the distributors, would be to read as many (at least 2-3) distributor agreements - as this will give you a good understanding of what to avoid/focus on/address when dealing with them. You can find some free examples online.
I just recently finished drafting such an agreement for one of my clients and would be happy to give you some pointers if needed.
Good luck

Online is the best place to sell your physical product. People nowadays tend to visit more the online world rather than the physical stores. You could possible sell out your products fast, be it clothing apparels, appliances, foods, etc. More so you can monitor it easily.

I hope this helps you a lot. if you have more questions in mind, please don't hesitate to call.
Thank you.
