The Live Seller & Reseller's Dilemma
Every reseller and live streamer eventually reaches the same point. Business grows across multiple channels—Whatnot shows, Poshmark closets, Palmstreet streams, Shopify storefronts, local buys, and estate sales. Before long, it becomes difficult to answer simple operational questions:
Most sellers resort to complex spreadsheets or messy notes that break as volume grows.
Beams Vault Was Built to Solve That Problem
This isn't just another generic inventory tool. It is being built as the operating system for modern resellers and live sellers—whether you're a weekend hobbyist, a Whatnot streamer, a Poshmark Ambassador, a Palmstreet host, or managing thousands of cross-platform listings.
Instead of spending hours wrestling with spreadsheet formatting, spend your time sourcing inventory, hosting great shows, and growing your business.
📦 Category-Aware Smart Inventory
Different categories require different inventory structures:
- Multi-category support (Cards, Apparel, Coins, Jewelry, Toys)
- Automated SKU generation & storage bin location tagging
- Quantity lot tracking & custom condition grading
Whether it's a graded sports card, vintage apparel, a coin, or a collectible, your inventory understands its attributes.
⚡ Multi-Channel CSV Exporters
Every platform requires different column rules and templates.
- Whatnot: Pre-formatted live stream catalog & flat-rate CSVs
- Poshmark: Ambassador-ready bulk listing exports
- Palmstreet: One-click auction set exports
- Shopify: Product inventory sync & template exports
Never suffer rejected CSV uploads or manual column re-mapping again.
