A coordinated learning and decision toolkit — not an accounting system or automatic store integration.
Understand operating revenue, refunds, channel contribution, advertising economics and working capital. A 15-page manual field-mapping guide covers Shopify, Etsy, Amazon and Stripe with examples and limitations.
Review normalized sale, refund and expense records, examine warnings, then import a verified XML/JSON pair into the Excel ledger on supported Windows setups.
A profitability ledger, a Pricing & Advertising Lab and an Inventory & Cash Planner. The companion models operate independently from imported ledger data.
Keep your platform exports, then normalize the relevant records into the included CSV schema. Genuine Shopify, Amazon, Etsy and Stripe exports are not accepted directly.
Use the local HTML validator. Resolve failures and review warnings. Import the paired export using Windows PowerShell and desktop Excel.
Require the ledger's DATA QUALITY = OK and IMPORT REVIEW = MATCH, reconcile against source records, then explore independent pricing and cash scenarios.
The included instructional example starts with 48 fictional orders, allocated to 57 sale lines, 6 refund events and 4 expenses. Its figures demonstrate how the workflow behaves; they are not typical results or earnings claims.

The Excel import workflow requires a Windows computer, Windows PowerShell 5.1 and locally installed desktop Microsoft Excel.
Targeted native tests passed on Windows with desktop Excel 2007 and with Microsoft 365 desktop Excel version 2608, build 20326, on one Windows 10 PC. Other Office builds, updates and enterprise security policies are not guaranteed.
Excel for Mac, Excel for the web, Google Sheets and LibreOffice. Importing raw platform exports without manual preparation is also unsupported.
Limits, warnings, recoverable inventory value and source reconciliation are explained in the included Compatibility & Limits guide. The validator's warning acknowledgement is not independent verification.
No. You must manually normalize records into the supplied CSV schemas before using the offline validator. The included platform field-mapping guide explains the steps for Shopify, Amazon, Etsy and Stripe. There is no direct API connector.
The supported import workflow is Windows desktop Excel with PowerShell 5.1. Mac, Excel for the web, Google Sheets and LibreOffice are not supported for this workflow.
The included HTML preflight tool is designed to process normalized CSVs locally in the browser. You should retain and safeguard source records and inspect the installed workflow before use; the product does not provide an online merchant account integration.
No. Its tax memo is illustrative and does not assess tax due. Your financial, accounting and tax obligations require separate verification.
