What a marketplace does well
A marketplace is unbeatable for discovery: it shows you who exists, roughly what things cost, and what the standard specifications look like. For simple, low-risk products in small quantities, buying directly is often the sensible choice.
Where it stops helping
A platform cannot tell you whether the seller owns a factory, cannot inspect your goods, and cannot negotiate in Mandarin on your behalf. Its protections cover the transaction, not the outcome, and 'the goods arrived' is not the same as 'the goods are right'.
What an agent adds
- Verification that the supplier is a manufacturer, on site
- Negotiation in the supplier's language, at the supplier's cultural pace
- Sample management and written specification control
- Pre-shipment inspection before your balance is paid
- Consolidation of several suppliers into one shipment
A simple decision rule
If the order is small, the product is standard, and a bad batch would be annoying rather than fatal, buy directly. If the order is large, the product is customised, or a failure would take out your season, the cost of an agent is insurance you can price in advance.
Many importers use both: the marketplace to discover and compare, an agent to verify, negotiate, and control the goods that actually ship.
