Direct answer
- Do not decide from the storefront alone. A supplier can have a decent Alibaba page and still leave too many gaps for your specific order.
- For a first payment, legit should mean more than existing as a company. It should mean the evidence is clear enough for this quote, this product, and this order size.
- If the supplier sounds friendly but the quote, PI, payment entity, or product details do not line up, slow down before paying.
