The real margin is often hidden in sourcing. Many Amazon sellers stop the analysis too early. They find demand, check competition, estimate price, and assume the opportunity is clear. But the business case is not complete until sourcing enters the picture. A product can look attractive in research, but become much less attractive once you factor in: • supplier reliability • quality control • packaging • shipping • lead times • returns • small product improvements • unexpected production costs The strongest product ideas are not always the ones with the biggest demand. They are the ones where market opportunity and sourcing reality work together. That means sellers need to evaluate products not only by what customers want, but by what can actually be produced, delivered, improved, and scaled profitably. AI tools like Wizium AI help Amazon sellers bring more structure into this process, connecting product research with smarter decision-making.
