01 — The Amazon Seller Workflow
How Glassio Works with Amazon Seller Central
Amazon Seller Central provides sellers with detailed inventory and sales reports that can be exported as CSV files. Glassio is designed to work directly with these reports — bringing your Amazon product data into a clean, powerful Mac-native workspace.
Export from Seller Central — Download your inventory report, FBA inventory report, or restock report from Amazon Seller Central as CSV
Import into Glassio — Load your Amazon CSV report into Glassio and instantly view your full inventory catalog organized by ASIN, SKU, and quantity
Track and manage — Monitor stock levels, set restock thresholds, log costs, and categorize products across FBA and FBM fulfillment methods
Export for updates — Generate updated inventory or pricing CSV files ready for bulk upload back to Seller Central
No Seller Central API connection required. Glassio uses the standard CSV workflow Amazon already provides. Your sensitive seller data — margins, costs, pricing strategy — stays on your Mac.
02 — What You Can Track
Complete Amazon Inventory Management on Mac
Amazon sellers need to track more than just quantity. Glassio gives you a structured, flexible inventory system for everything that matters to your Amazon business:
Track available stock and inbound FBA quantities per ASIN and SKU
Monitor stranded inventory and flag items needing attention
Record COGS (cost of goods sold) per unit for profitability analysis
Track supplier information, lead times, and reorder points
Manage multiple product variations (size, color, bundle) in a single catalog view
Add custom notes per product — useful for restricted item compliance or condition tracking
Monitor inventory age and storage fee risks for FBA items
03 — Local-First Advantage for Amazon Sellers
Protect Your Business Data
Amazon seller accounts are high-value targets. Connecting third-party tools via API increases the attack surface on your business. Glassio eliminates this risk entirely:
No API connection to your Amazon account — Glassio never touches your Seller Central credentials
Offline-capable — Manage your full inventory catalog even when traveling or without Wi-Fi
Private cost data — Your COGS, margins, and supplier prices never leave your Mac
No monthly fees — Unlike most Amazon inventory tools, Glassio is free or a one-time purchase
Full data ownership — Export your entire database as CSV anytime, with no vendor lock-in
Ideal for Amazon FBA sellers, private label brands, and wholesale Amazon businesses who want a fast, private, and reliable inventory management tool running natively on macOS.
Private label brands — Manage your full product catalog with cost, pricing, and margin data
Wholesale sellers — Track bulk inventory across multiple ASINs and supplier batches
Retail arbitrage & OA sellers — Log purchase sources, costs, and ROI per unit
Collectibles & media sellers — Track unique items, condition grades, and individual valuations
Multi-channel sellers — Combine eBay, Amazon, and Shopify inventory into one Mac dashboard
