When choosing a product, supply, cost, packaging and after-sales processes matter alongside demand. A single trend list does not make a sound business plan.
Validate demand on a small scale
Review potential customers' questions, competitors' product information and your existing sales data. Keep your initial catalogue to a manageable size.
Understand operational costs
Consider lead times, minimum orders, storage, breakage or spoilage, shipping volume and the likelihood of returns together. Calculate approximate contribution per product using your own real inputs.
Build your difference into the product or experience
The product itself, your technical expertise, content quality or service can be a reason to choose you. Explain that difference on your website with verifiable information.
