Every repair shop that scales up eventually places its first big screen order — usually to a supplier found on Alibaba or at a trade fair. The difference between a good supplier and a bad one is not price; it is what happens when something goes wrong. Ask these questions before the first wire transfer.
Ten questions that matter
- What is your QC process? Look for per-unit touch, brightness, and True Tone testing — not batch sampling
- What is the claimed defect rate? Honest suppliers say 1–3%. "Zero defects" means they do not track it
- How do you handle DOA claims? You want photo-based claims within 14 days and credit on the next order
- Do you stock, or drop-ship from the market? Stocked goods = stable grade; market-sourced = quality lottery
- Which panel types do you carry per model? One tier per model means a trader; a real wholesaler offers copy/hard/soft OLED
- What are your payment terms after the first order?
- How do you pack? Foam-slot cartons survive DHL; bubble wrap alone does not
- Can I mix models and tiers in one trial order?
- Who pays return freight on defects?
- Can you ship DHL today? Same-day dispatch is the single best signal of a real warehouse operation
