Which Amazon report does this tool support?
It is designed for the Flat File V2 Settlement Report, report type GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2. The parser expects the amount-type, amount-description and amount columns used by that report.

Two-period Flat File V2 comparison
Find what changed between two Amazon settlements.
Drop one earlier settlement and one later settlement. The auditor compares signed amount rows, raw amount descriptions and SKU-level row net locally in your browser.
What this is built to catch
A fee or amount description that appears for the first time in the current settlement.
A sharp increase in total deductions, fee deductions, advertising deductions or refund-related drag.
SKUs whose signed Amazon-side row net deteriorated the most between periods.
Large raw amount-description changes that deserve reconciliation before you assume they are normal.
Commercial wedge
Free now: compare two files. Paid later: keep the history and watch every period.
A subscription only earns its fee if it removes repeated manual work: retain period history, reconcile recurring exports, alert on fee drift, join COGS and advertising data, and preserve evidence for follow-up. This free tool does not claim that automation exists yet.
See paid workflow optionsamount-type, amount-description and amount fields, but the possible values can evolve. This auditor therefore keeps raw description deltas visible and uses broad heuristic buckets only as an investigation aid. It does not decide whether a charge is erroneous or reimbursement-eligible.FAQ
Does Solarc Labs upload or store my settlement files?
No. The comparison runs in your browser session. The files are read locally and are not sent to Solarc Labs by this tool.
Is row net the same as Amazon profit?
No. Settlement rows explain Amazon-side money movements. They do not automatically include all COGS or other off-Amazon costs, so row net should not be treated as accounting profit.
Why compare two settlement periods instead of analyzing one?
A single settlement explains one period. A two-period comparison makes it easier to spot what changed: new fee descriptions, higher deductions, refund drag, advertising changes and SKU-level deterioration.

Can the value land before the explanation?
Use this as a silent-demo production template for Shorts, Reels, TikTok, a launch GIF or a community post. The first second should show the tension or transformation — not a logo, setup screen or narrated promise.
Vertical capture · 9:16
405×720 reference · 10s
Keep the actual input, primary action and proof result inside the central vertical frame; browser chrome is not the product proof.
Append ?wow=1 for the deterministic capture helper. It injects input only when an owned synthetic fixture exists, then captures the real tool action and result.

Safety / truth boundary: use synthetic or public-safe demo data only. Never show secrets, private customer material, fabricated metrics or a pass/certification claim the tool does not actually produce. This template improves demonstrability; it does not promise reach or virality.
