In dropshipping, you never see the parcel. Your customer does, and your customer reviews your store, not the AliExpress seller. That makes supplier vetting the most important step in the business and the one most tooling skips — importers pull listings into your store in one click and tell you nothing about who ships them. This guide to choosing AliExpress suppliers for dropshipping is the vetting process itself: what to read on the store and the listing, what to test with an order, and how AliScore runs the first half of it on every product and search page so research goes faster.
Why the supplier matters more than the product
A dropshipping store's refund rate, review score and ad economics are set by two things the customer experiences: did it arrive when promised, and was it what the page showed. Both are the supplier's behaviour, not the product's. The same phone case from two sellers can produce a 2% refund rate or a 15% one. Product research finds items that sell; supplier vetting decides whether you keep the money.
Stage 1: The store, read strictly
Open the seller's store page from the listing. AliExpress store feedback clusters between 90% and 100%, so read it on a stretched scale:
- 98% and up: excellent. The store you want to build on.
- 96–97.9%: good. Normal for an established, competent seller.
- 93–95.9%: average. Acceptable for low-value items only; read the negatives first.
- Below 93%: do not list. Their complaints become your complaints.
Then followers. Thousands means years of trade and repeat buyers. Hundreds is a small store that may struggle with a spike in your orders. Dozens means new, and new suppliers vanish — with your orders in flight.
AliScore's seller trust score encodes this: 70% weight on the feedback rate with 85% mapped to zero, 30% on followers on a log curve, labelled Trusted through Risky. The formula is public.
Stage 2: The listing's review shape
You are not reading the star rating. You are reading:
- Review count. Below ten, the rating is meaningless; below a hundred, thin. For a product you will sell at volume, you want hundreds of reviews so the failure modes have had a chance to appear.
- Negative share. Over roughly one review in ten negative is a product with a pattern. That pattern becomes your refund rate. AliScore reads the positive-versus-negative split from AliExpress's public review statistics and warns past the 10% line.
- What the negatives say. "Slow shipping" is the channel, and you can change it. "Stopped working after two weeks" is the product, and you cannot.
- Photo reviews. Real buyer photos tell you what your customer will unbox. Compare them to the gallery you are about to copy into your store.
- Date spread. Reviews across a year or more mean the product has survived real use. All recent means it has not been tested yet.
The fake review guide covers judging whether those reviews are genuine.
Stage 3: Shipping consistency
Your customer's tolerance is set by what your store promised. Check on the listing:
- Which shipping methods are offered to your customers' countries, and the estimated windows for each.
- Whether the seller ships from a local warehouse for your main market. Platform-fulfilled listings often do, and their timelines are more predictable.
- What the recent reviews say about actual delivery time versus the estimate. A seller consistently missing the window will miss yours.
Stage 4: Talk to them
Send the seller three specific questions: can they handle repeat orders without branded inserts or invoices in the box, what is the processing time before dispatch, and what happens if an item arrives damaged. A supplier who answers all three, clearly, within a day is a supplier who will answer when an order goes wrong. Silence or a copy-paste is the answer too.
Stage 5: Order it yourself
Non-negotiable for anything you intend to sell at volume. Place a real order to your own address, at the shipping tier your customers will get. Time the dispatch, time the delivery, open the box as a customer would, use the product for a week. This is the only check that catches a good store shipping a bad batch, and it costs one unit.
Stage 6: Keep two suppliers per product
Sellers go out of stock, raise prices and close. The store with a single supplier per product discovers this from a customer email. Vet a second seller for every product you rely on before you need one.
Where an extension fits
Stages 1 and 2 are public numbers on the page, repeated across dozens of candidate listings a day, which is precisely the work a browser extension should absorb. With AliScore installed:
- Search and category pages show a score badge on every card, so weak listings are visible before you click. A hollow badge is an estimate from the card; hover or click to verify it. A Best Deals row at the top lists the five highest-scoring visible cards as a first shortlist.
- Product pages show the 0–10 score, the separate seller trust score, the review split, the four-component breakdown, and named warnings — thin reviews with the actual count, negatives over 10%, a store in the Caution tier or worse, weak value.
- Verified scores are cached for 72 hours on your device, so re-checking candidates costs nothing.
It does not import products, sync stock or track prices — it is a vetting tool, not a store tool — and its scoring formula is published so you can decide whether the weights suit your category. Stages 3 to 6 stay with you. No extension can order a sample, and none should.
The process, on one line
Feedback 96%+ and followers in the thousands; hundreds of reviews with negatives under 10%; shipping windows the reviews confirm; a seller who answers; a test order; and a second supplier vetted before the first one fails.
