Welcome to SaleHoo paqjoan,
The first thing we suggest you do is read through our Link hidden: Login to view
especially our New User Manual, to help you get around SaleHoo as well as to help you start on the right foot when contacting suppliers and doing your own market research!
You might also want to give our SaleHoo Research labs a try o help you find profitable niches to sell on ebay.
Once you have read through our guides, it would be time for you to decide what type of products you want to sell. Generally it's best to start selling something you are interested in because you are going to be spending a LOT of time thinking about it! Do you love fashion or movies? Perhaps you feel excited about the thought of new gadgets and technology? It's likely that there are plenty of other people who also share your interest - giving you an instant audience for your product. One idea is to jot down your interests and then make a list of products that are related to these interests (we recommend staying away from electronics to begin with as warranty issues can be complicated to manage).
Once you've thought of a couple of ideas, it's time to start researching suppliers. This is where SaleHoo comes in. Use the search box to look for the product(s) you want to sell. When you've found some suppliers who fit the bill, send them an email asking what the best possible price is that they can give you for the products you wish to buy. A small tip for you: if you buy 20+ units at a time, you should be able to negotiate a better deal. It's also a good idea to contact more than 1 supplier before you start buying to compare prices.
Hope this helps you off to a good start! All the best :)
