What Flywheel by Sellistix is
Flywheel by Sellistix is a web service for sellers who need to reconcile Amazon US and Walmart US settlements and follow related returns, inventory, and operational costs. It traces payouts to fee lines, orders, and raw reports, with tie-out badges accurate to ±$0.01. Settlement lines can be filtered, sorted, paginated, and exported to CSV or XLSX. Returns are linked to their original orders and matched to refund fees once settlement catches up. Inventory tools cover movement history, multiple locations, suppliers, purchase orders, replenishment, adjustments, and write-offs. Operational COGS is based on supplied unit costs and marketplace orders; it excludes marketplace fees, paid shipping, operating expenses, and sales outside connected marketplaces. Amazon connects through Seller Central sign-in, while Walmart connection is assisted during beta. Flywheel is in invite-only beta, admitting sellers in waves.
