SuppliFlex is a real-time supply chain operations platform for US product brands doing $500K to $50M a year: inventory, orders, purchasing, fulfillment and accounting sync in one system of record. It keeps one append-only ledger across Shopify, Amazon, wholesale, 3PLs and QuickBooks, and routes only what needs a human decision into an exception inbox that says what happened, why it matters and what to do, with a one-click fix. Multi-location stock, lots and expiry, landed cost, three-way match and valuation are included; micro-WMS and micro-TMS are add-ons. The sandbox is the real product on seeded data: pick a demo brand, get 18 months of history, open POs and live simulated channel events, and open a workspace in under a minute with no card and no setup.
