Flywheel by Sellistix review
A focused reconciliation tool for Amazon US and Walmart US marketplace operations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Flywheel by Sellistix is marketplace settlement reconciliation software for sellers operating on Amazon US and Walmart US. It is also positioned for 3PLs, prep agencies, and firms supporting multiple marketplace accounts. The web-based product connects marketplace settlement data with fee lines, orders, returns, refunds, and raw reports. It also includes operational COGS based on seller-provided unit costs, product catalog management, and inventory tracking.
Pricing is structured across four monthly tiers: Tier 200 costs $39 per month, Tier 750 costs $59, Tier 1500 costs $99, and Tier 3000 costs $179. Each plan includes settlement reconciliation across Amazon and Walmart, return-to-order linking, operational COGS, an inventory ledger, and product catalog management. A 14-day trial is available. The plan structure gives marketplace operators a clear entry point, while higher tiers provide options for larger operational volumes.
Flywheel’s main strength is its narrow connection between settlement detail and marketplace operations. Users can export settlements to CSV or XLSX, review inventory quantity and movement history, manage suppliers and purchase orders, and switch between multiple client accounts from one login. Amazon US is self-serve during the invite-only beta, while Walmart US connection is assisted. The product should suit operators who need marketplace-specific reconciliation and related inventory workflows in one web application. It is less suitable for businesses seeking broad marketplace coverage or accounting, tax, bookkeeping, or full profit-and-loss software.
