See what you actually keep on every Walmart Marketplace & Amazon sale
Marketplace payouts hide the truth in dozens of fee lines. Upload your settlement or reconciliation report and MarginGuard Pro shows revenue, fees by type, refunds, net payout and estimated profit after your cost of goods — per SKU. Profit alerts flag losing SKUs, and PriceGuard margin protection warns before a price change wipes out your margin. Included in MarginGuard Pro.

What you get
Drop in your reports
Amazon Settlement Flat File V2 (tab or CSV) and Amazon transaction (date range) reports from Amazon.com, .in, .com.mx, .com.br, .ca, .co.uk and .de — including German, Spanish and Portuguese headers and decimal commas — plus Walmart Marketplace reconciliation reports. We detect the format and marketplace, or you pick them.
Local currency
Results in the report's own currency (USD, INR, MXN, BRL, CAD, GBP or EUR), with an optional USD view at a fixed, dated, approximate rate. Fee notes per marketplace are estimates that vary by category.
Profit per SKU
Units, revenue, fees, net payout, your cost per unit (editable, remembered in your browser), estimated profit and margin.
Fees by type
Commission, fulfillment, storage, advertising, promotions… each as a share of revenue so you see where margin leaks.
TrueProfit alerts
Profit alerts up top: losing-SKU flags with your own threshold ($ or margin %), total estimated loss and worst offenders, Amazon vs Walmart Marketplace profit for matching SKUs, and a what-if forecast for price and ad-spend changes.
PriceGuard margin protection
Set a minimum profit floor (% or $, globally or per SKU). See which prices break it, when a small price drop would wipe out the margin at your current fees, and a recommended price that protects the floor — with the math shown.
Export
Download a per-SKU CSV and a summary CSV for your books or spreadsheet.
Who it's for: Walmart Marketplace and Amazon sellers who want a clear view of margin per SKU without sending their data anywhere.
Same report, second check: FeeAudit
The settlement or reconciliation report you use here also works in FeeAudit, which flags fulfillment and referral fees that look too high and estimates what may be recoverable. $14.99/mo for FeeAudit on its own, or $34.99/mo for the Full Suite (all four tools).
