Real sellers. Real numbers.
I went from a notes app and three browser tabs to one dashboard. I finally know which pairs actually make money.

Spreadsheets and sticky notes used to eat my Sundays. Now every item I'm selling lives in one place and I always know my margin.

FAQ
Questions, answered.
No. Your first month is free and we never ask for a card to begin. Add billing only when you decide to continue.
Not yet. Today Backstock is your inventory workspace — you track what you own, set asking prices, and manage what's for sale in one place. Cross-posting to external marketplaces is on our roadmap and coming soon.
Yes. Bring a spreadsheet of any size, map your columns once, and we'll bulk-create everything — SKUs, costs and photos included.
Every sale subtracts your cost basis automatically, so the P/L you see is true net profit, not gross.
Your inventory and sales data is private to your account, never sold or shared, and encrypted in transit and at rest.
Nothing breaks. Bulk tools and higher limits are there when your volume grows.
