Marketplaces don't reward the best product. They reward the seller who prices on sold data, lists so buyers can find it, ships fast and cheap, and protects their seller metrics. Do those four and you beat 90% of casual sellers — whether you're moving enterprise networking gear, a piano, or a drawer of old RAM.
Active listings are asking prices — fiction. Sold listings are the market. Before you price anything:
real example: selling an enterprise access point? "Aruba AP-655" as an exact model number in the title sells to buyers searching that part. "Wifi access point, great condition" sells to nobody. Model numbers are the whole game in tech gear.
eBay gives you 80 characters — spend them like money: brand + exact model + key specs + condition. "HPE Aruba AP-655 WiFi 6E access point, tested" beats "great wifi ap". Front-load the words a buyer would type.
8–12 photos minimum: front, back, ports, labels/serial plates, and every flaw close up. Daylight or white background. For gear, one photo of it powered on is worth a paragraph of description. Flaw photos build trust and kill "not as described" returns.
Brand, model, MPN, condition, connectivity — eBay's filters run on item specifics. An unfilled specific is a buyer who filtered you out. Copy the specifics from the best-selling comp listing.
Commodity gear with known sold prices: fixed price, always. Auctions only for genuinely rare items with uncertain value — and start them at the lowest price you'd accept, not $0.99 theater.
real example: a 3 lb access point ships USPS Ground Advantage for roughly half of Priority Mail on Pirate Ship — same 2–5 day window for most zones. Check both before defaulting to Priority.
Review every listing older than 30 days: drop the price 5–10%, refresh the title, or end and relist to reset search freshness. eBay's Markdown Manager (Seller Hub > Marketing) runs scheduled sales without touching your base price.
Start at 2–5% ad rate on slow movers only. Never promote your best sellers — they sell on their own and you'd just pay eBay a cut for nothing. Kill any promoted listing that gets clicks but no sales after two weeks.
Defect rate, late shipment rate, and tracking-valid rate decide your search placement and your 10% final-value-fee discount. One "item not as described" case costs more than the refund — photograph flaws, describe honestly, ship on time.
Tools like Vendoo and List Perfectly push one listing to eBay, Facebook Marketplace, Mercari, and more — with auto-delist when it sells somewhere so you never double-sell. Worth it past ~20 active listings; below that, manual cross-posting of your best items is fine.
Accepting 30-day returns costs you a few return labels a year. Fighting returns costs you defect-rate hits, negative feedback, and hours of messages. The math isn't close — accept returns, price 2% higher to cover it.
