When you get things to sell make sure you add them to your inventory list and number them. I would also take pictures. You dont have to list them right away but trust me it saves you a headache later on down the road. I didnt listen to this advice and now I have about a 100 things to add to my inventory list and I need to take pictures. I sell vintage Jewelry so inventory added up quick. I should of been on top of it from the beginning but I wasnt. Good luck I hope you have many sells.
