1. The Five Questions That Filter Suppliers Fast

Ask these before quoting anything. Who maintains the firmware? (If the answer is 'the app company you cannot contact,' walk.) What is the warranty process — return-to-where, and who pays? Which compliance documents exist TODAY for your market (FCC, CE, UKCA — see our certifications guide)? Is neutral or your-brand packaging actually available at your order size? What is the honest restock lead time? Factories that answer all five specifically are rare and worth keeping; trading companies resell the same SKUs with vaguer answers each time.

2. Dropshipping vs Small-Wholesale: Pick Your Model Knowing the Trade

Classic dropshipping (factory ships each order blind to your customer) works for validating a niche but caps margin and control — you inherit the supplier's fulfillment errors as your reviews. The model most successful dash cam sellers converge on is small-batch wholesale: 50-100 units of two or three proven SKUs, stored locally, shipped same-day by you, with the factory supporting warranty and restock by air in under a week. Margin roughly doubles, reviews stay yours, and cash exposure is a few thousand dollars, not a container.

3. The SKUs That Actually Move for New Sellers

From our wholesale order data, new stores succeed with a narrow catalog: one proven dual-channel bestseller (A5-class, 4K+2K at entry factory pricing), one three-channel with IR cabin (G12-class — the rideshare and fleet crossover), and one premium differentiator — a wireless CarPlay console (T60, CP7) or a 4-lens 360 unit (M77) that competitors in your niche likely do not carry. Three SKUs, one supplier, one warranty process. Stores that launch with twenty SKUs spend their energy on stock, not marketing.

4. Private Label: What 'Your Brand' Really Requires

Private label on dash cams is genuinely available — we ship neutral units with customer branding at MOQ 1 pc for box and boot-screen logo — but two costs surprise new sellers. First, firmware branding (your logo in the app and boot screen) has a one-time engineering setup per model. Second, compliance documents carry the brand name that ordered them: your label needs its own FCC/CE declarations listing your brand, which your factory supplies for the paperwork. Budget both; they are the difference between a real brand and a sticker.

5. Red Flags and Green Flags, From Inside

Red flags: prices far below the factory floor (refurbished or bait), 'any certification you want' promised instantly, no video call with an actual engineer, MOQ talk that shifts upward after the first order. Green flags: they ask about your market and laws before quoting, warranty terms volunteered in writing, honest 'this model is not right for you' moments (we turn sellers away from 4G SKUs when their market's networks do not support the bands), and engineers reachable on WhatsApp during your daytime. Choose the supplier who occasionally tells you no.
