What is product sourcing?
Simply put, product sourcing is finding the products you want to sell in your store, buying them from a supplier, and then reselling them.

5 steps to successful product sourcing
Sourcing new products can seem overwhelming — it’s not as simple as just finding a great product and putting it in your stores. But there are steps that retailers can take to make the process flow smoothly.

1. Research your product;
First and foremost, retailers
need to understand the product. Market research is essential to success; sourcing products without the necessary research is asking for failure. The research retailers need in-hand should be well-rounded.
2. Contact any potential suppliers;
Before contacting suppliers, know exactly what it is you, as the buyer, need. Yes, part of this is doing research on the product, as mentioned above. But the other part of it is knowing what you want out of this initial contact with the supplier. Are you looking for information? For samples? Specific products? Knowing that, and being upfront about your needs, will help the process go smoothly.
3. Ask for samples;. As a retail buyer, you’re not going to put a product in your store without sampling it. When contacting suppliers, part of the ask should be for samples so you can get feedback from team members, view the product up close and personal, and see how the supplier handles this first transaction before you make the decision on whether to include it in your product mix. Asking for samples is an important part of your sourcing strategy and a good way to test the quality of products.
4. Choose supplier to trial-run an order;
Once a retail buyer finds a product that shows potential, order a trial-run for that product. This can mean the buyer asks for a certain number of units to be trialed across a retail chain, or it can mean a product is being tested in only certain stores.
5. Evaluate supplier;
Whether or not a buyer chooses to move forward with a supplier and form a more long-term relationship depends heavily on how the supplier performs during a trial run. Having the parameters mentioned above will help retail buyers better evaluate suppliers when the trial run ends. Did the product meet the expected goals? Did it overperform or underperform? How was it received in the stores?
