Supplier Vetting
Supplier vetting is the process of verifying a supplier before partnering — checking order fulfillment times, product quality, returns handling, and ability to scale. A bad supplier can destroy a store with a great product through delays, poor quality, and lack of communication. Good supplier vetting is the foundation of a stable dropshipping business.

What Is Supplier Vetting?
Supplier vetting is the systematic process of evaluating a supplier before formally partnering with them. In dropshipping, the supplier is responsible for product quality, order fulfillment time, and returns handling — a supplier's mistake directly hits your store's reviews, return rates, and ad campaign profitability. A solid supplier vetting process prevents the most costly mistakes in building a dropshipping business.
Why Supplier Vetting Is Critical
Typical consequences of a bad supplier: - **Long delivery times** (3–6 weeks instead of the promised 7–14 days) destroys ad campaign ROAS — customers file PayPal disputes, card chargebacks, and the cost of customer support eats the margin - **Quality drift at scale** — the first orders look great, after 500 orders quality drops, reviews tank - **Ghosting after a dispute** — the supplier stops responding after the first mass return or chargeback - **Inability to scale** — when orders grow from 10 to 200 per day, the supplier can't keep up, backorders appear
Step-by-Step Supplier Vetting Process
**Step 1 — Sample Order** Order the product as a regular customer. Check: actual delivery time (not declared), packaging quality, product quality vs. photos, accuracy of technical specifications. Order at least 2–3 units of different variants.
**Step 2 — Communication Speed Test** Send a message with a technical question (e.g., about variant availability or custom packaging) and measure response time. A good supplier responds within 24 hours on business days. Over 48 hours — red flag.
**Step 3 — Scale Capacity Check** Ask directly: "How many orders per day can you handle for this product?" and "What's your current stock or production lead time?" A good supplier gives specific numbers, not general reassurances.
**Step 4 — Returns and Disputes Policy** Ask about the returns procedure (who pays for shipping, within what timeframe, what defect rate is acceptable). No clear returns policy = problem at the first mass return event.
**Step 5 — Payment Terms Negotiation** At small volumes, accept standard terms. At 200+ orders per month you can negotiate: net-15 instead of prepayment, volume discounts, custom packaging at a specified MOQ.
Supplier Landscape for Dropshipping
**AliExpress** — starting point for most. Millions of products, no minimum order, built-in reviews. Delivery time to Europe: 7–20 days (ePacket/AliExpress Standard Shipping). Downsides: variable quality, returns handling often difficult.
**CJDropshipping** — verified agent with its own warehouse. Faster shipping (5–12 days to Europe), custom packaging at low MOQ, better returns handling. 10–20% more expensive than AliExpress.
**Spocket** — suppliers from the USA and Europe. Delivery time 2–5 days. Higher product prices but higher quality and ability to build a premium brand. Best for USA/UK markets with premium positioning.
**DSers** — integration tool for AliExpress + official Shopify partner. Not a supplier — it's an order management interface for AliExpress.
**Zendrop** — similar to CJ, focused on USA. Fulfillment automation, custom branding.
**Branded sourcing agents** (e.g., Sup Dropshipping, Wiio, USAdrop) — private sourcing agents. They negotiate prices directly with factories, organize custom packaging, manage QC. Worth it at 50+ orders per day.
How to Vet on AliExpress Specifically
- **Review count and photo-review ratio** — reviews with photos are harder to fabricate. Look for at least 200+ reviews, >20% with photos. - **Store age** — minimum 1 year. Stores under 6 months are a red flag. - **Response rate** — look for >90%. A seller with <70% response rate is practically unreachable when problems occur. - **Shipping options** — check availability of AliExpress Standard Shipping or Cainiao Super Economy Plus to your market. Don't accept shipping only via China Post Ordinary Small Packet (30–60 day delivery times).
The "3 Suppliers in Parallel" Tactic
Don't test one supplier at a time. Order samples from 3 different suppliers of the same product simultaneously. Compare: delivery time, quality, communication. The best one gets the first production orders. Keep the second as backup — at the first sign of problems with the main supplier, you have a ready solution without delays.
Contracts and MOA at Scale
At 200+ orders per month, it's worth formalizing the partnership with a Memorandum of Agreement (MOA) or a simple contract that specifies: expected fulfillment time, quality standard (with a defined acceptable defect rate), dispute procedure, penalties for delays, and payment terms. Most sourcing agents are used to this.
Frequently Asked Questions
What is supplier vetting?
Supplier vetting is the process of checking a supplier before entering a dropshipping partnership. It includes placing a sample order, testing communication speed, verifying scale capacity, and checking returns policy. The goal is to ensure the supplier will deliver the product on time, at the right quality, and won't disappear when problems arise.
How long does supplier vetting take?
Full supplier vetting typically takes 2–3 weeks — that's how long a sample order takes (7–15 days delivery), quality assessment, and several rounds of communication. For an urgent product launch you can compress to 10 days by ordering express shipping, but never skip the sample order step — it's the most important one.
What's the difference between AliExpress and CJ Dropshipping?
AliExpress is a marketplace with millions of products — no intermediary, direct contact with hundreds of independent sellers, no MOQ, but variable quality and slower communication. CJDropshipping is a verified sourcing agent with its own warehouse — faster shipping, better returns handling, custom packaging at low MOQ, but 10–20% higher prices and a smaller product selection.
Should I always order a sample first?
Yes — always. A sample order is the only reliable way to verify actual delivery time, product quality, and packaging standard. AliExpress reviews can be fabricated, photos may be stock images or from a different variant. The cost of a sample ($10–30) is the best investment before spending $500–1,000 on an ad campaign for an untested product.
What red flags should I watch for during supplier vetting?
Red flags: contact only via WeChat without verifiable business data, no business license or refusal to show one, refusal of sample orders, response time over 48 hours, only Mandarin communication without English translation, AliExpress store younger than 6 months, no photo reviews, no option to ship via tracked method to your market.
