Mission
An inventory tracker for small eBay sellers is one of the better “boring but profitable” niche SaaS ideas because many part-time resellers still manage stock with messy spreadsheets, handwritten labels, or memory. The opportunity is not competing with enterprise inventory software — it’s building something simpler, cheaper, and tailored to solo sellers and side hustlers. ⸻ The Core Problem Small eBay sellers struggle with: * losing track of inventory locations * accidentally overselling * forgetting sourcing costs * poor profit tracking * inconsistent SKU systems * bookkeeping headaches * managing cross-posting to Vinted/Facebook Marketplace/Depop/Etsy Most existing tools are: * too expensive * too complicated * designed for warehouses * overloaded with enterprise features That creates a strong niche. ⸻ Ideal Target Customer Start narrow. Best starting audience: * UK-based part-time eBay resellers * 50–500 active listings * selling from home * sourcing from charity shops/car boots/wholesale clearance Examples: * sneaker resellers * retro gaming sellers * clothing flippers * electronics refurbishers * trading card sellers ⸻ Your MVP (Minimum Viable Product) Do NOT build a giant platform initially. You only need 3–5 killer features. ⸻ Version 1 Features 1. Inventory Location Tracking Example: * Shelf A-3 * Garage Bin 7 * Loft Box 2 This alone solves a major pain point. ⸻ 2. Profit Calculator Track: * item cost * shipping * eBay fees * promoted listing fees * final profit Many sellers genuinely do not know their margins. ⸻ 3. SKU Generator Automatically create unique item codes. Example: GAME-2026-0142 Makes stock retrieval faster. ⸻ 4. Sold Item Archive Keep searchable history: * what sold fastest * average margin * repeat products This becomes valuable business intelligence over time. ⸻ 5. Barcode / QR Labels Users print labels and scan items with phone camera. This sounds advanced but is now relatively easy with modern no-code tools. ⸻ The Smart Positioning market it as: “The simplest inventory system for home-based eBay resellers.” Or: “Never lose stock again.” Or: “Know your real profit on every sale.” Specific positioning matters enormously. ⸻ Your edge: * ultra-simple * reseller-focused * mobile-friendly * cheap
