Vetting an AliExpress supplier on operational signals

Most supplier-selection advice is about ratings, feedback and store age. Those are worth a glance and they do not predict the thing that actually hurts you, which is operational reliability.

The signals that matter

Your metrics on every sales channel depend on three supplier behaviours: how fast they dispatch, whether the tracking number they give you is real, and whether they tell you when something is wrong.

None of those appear in a star rating.

Measure dispatch time yourself

Processing-time claims are marketing. The number you need is hours from payment to first carrier scan, measured across real orders.

Ten orders gives you a usable picture. Thirty gives you a distribution, which is more useful, because what matters is not the average but the slow tail - your handling time has to survive the bad cases.

Tracking quality is a supplier property

Some suppliers consistently issue identifiable carrier numbers that scan within a day. Others issue internal references that never scan, or generate numbers days before handover.

This is measurable from the same data: what proportion of their tracking numbers produced a first scan within 48 hours. A supplier below ninety percent on that measure is a Valid Tracking Rate problem waiting to happen.

Test communication before you need it

Send a question before you place significant volume. How fast they answer, and whether they answer the question asked, predicts what happens when an order goes wrong.

A supplier who is slow to respond when you are a prospective customer will not be faster when you are chasing a lost parcel.

Depth matters more than price

A supplier with one of an item is fine until you sell two. Ask about stock depth and lead time for restocking, particularly on anything you intend to list across multiple channels - where a stockout multiplies into cancellations everywhere at once.

A practical scorecard

• Median and slowest dispatch-to-first-scan, in hours
• Percentage of tracking numbers scanning within 48 hours
• Response time to a question, in hours
• Stock depth on your top items
• Whether they will ship without their own branding or inserts

That last one is a hard requirement on Amazon and good practice everywhere. Ask explicitly rather than assuming.

Always have a second

For any product that sells steadily, having a tested alternative supplier is worth the slightly worse price. The cost of the alternative is a few percent of margin. The cost of not having one is a cancellation cluster across every channel you list on.
