What people complain about in eBay

Capabilities people described needing that eBay does not give them, taken from the highest-scoring problems first. These are individual accounts written in each person’s own terms, so two entries may describe the same underlying gap in different words.

• A platform to bulk list and sell branded inventory across channels without individual brand approval
• Automotive parts location service that compares salvage yard inventory, eBay, and new OEM sources with compatibility checking
• Mobile app with part condition verification using photos and AI to detect cross-threading, cracks, or wear
• Vetted supplier marketplace with fraud prevention
• Automated inventory distribution platform replacing manual WhatsApp posts
• Secure cross-border payment and escrow system
• Multi-platform batch listing automation for clothing items
• Inventory prioritization system that identifies which items to list first based on market demand
• Visual recognition app for part identification from photos
• Compatibility verification database for plumbing parts
• Automated price comparison across seller platforms with unified trust metrics
• Curated and verified buyer reviews specific to used engine transactions
• Marketing automation that drives traffic without social media
• Centralized marketplace with IP protection and better sales volume for niche physical goods
• Automated marketplace performance analytics tool that compares sales data across platforms
• Centralized listing management for custom/made-to-order products across multiple marketplaces
• Tool that predicts marketplace fit based on product attributes like customization and fulfillment method
• B2B marketplace with vetted vintage clothing suppliers
• Quality verification system for bulk vintage purchases
• Supplier reputation tracking for vintage wholesale
• B2B marketplace for bulk selling automotive inventory without individual listing

The manual processes people built around the gap. A long workaround list is the strongest evidence a problem is real: someone is already paying for it in time. Where several people described the same workaround, it is marked.

• manually selling on eBay and via liquidators
• drives 100 miles to salvage yard for part
• checks eBay for used part
• plans to use thread chaser to fix cross-threaded port
• considers swapping metal body from old part to plastic of new one

• manually vets suppliers through social media contacts
• sources via Facebook Marketplace and Chrono24 internationally
• manually listing items on eBay one by one
• keeping 400+ items unlisted in storage due to listing bottleneck
• searching eBay for parts without compatibility verification
• posting photos to online forums for manual identification
• researches on eBay and official LKQ website to compare prices
• reads mixed reviews across the internet to gauge trustworthiness
• offering discounts to previous eBay customers via direct message
• sells on eBay, Mercari, and Facebook Marketplace as a slow trickle of revenue
• uses semi-hot water from a source to clean parts
• Manually comparing sales performance across Etsy and eBay
• Manually listing products on multiple marketplaces
• Handling fulfillment himself for custom orders without using FBA
