QuantSeller is a profit, pricing, and cost management workspace for Etsy makers and marketplace sellers.
Many sellers know their revenue, but not their real product profit. QuantSeller helps sellers calculate profit after materials, labor, packaging, shipping, marketplace fees, discounts, and Etsy Offsite Ads.
With QuantSeller, makers can build product cost structures, manage materials and BOMs, price products with full cost context, track marketplace performance, and understand which products are actually profitable.
The Etsy maker workflow is the main focus today. QuantSeller also includes marketplace seller tools for Amazon workflows, including FBA profit analysis, inventory visibility, order sync, and competitor monitoring features that are being expanded over time.
Key features include:
- Product profit and margin calculation
- Etsy fee, pricing, and Offsite Ads cost visibility
- Materials and BOM management
- Handmade product cost tracking
- Marketplace order and listing workflows
- SEO helper tools for product listings
- Amazon seller tools in beta for FBA and marketplace operations
QuantSeller is built for sellers who want to stop guessing prices in spreadsheets and make product decisions with real cost and profit data.
