Everything in one place
Eight modules, one calculation engine
Every number comes from the same backend engine and the same editable Amazon fee tables, so a profit figure means the same thing whether you typed it in, uploaded a CSV or asked Zoniq.
Product Research
Score an ASIN on profit, risk and opportunity before you spend anything.
OpenSupplier & Wholesale
Upload a price list or a 10,000-row catalog and get a buy / avoid call per row.
OpenPPC Analysis
Find wasted spend and negative keywords in a search term report. Never touches your campaigns.
OpenListing Tools
Generate, score and rewrite listing copy, and compare it against competitors.
OpenInventory Planning
Reorder dates, quantities and stockout risk for one SKU or a whole CSV.
OpenLaunch Planning
Budget a launch, find the break-even point and see the timeline before you commit.
OpenBulk CSV Tools
Run profit, ROI, fees or max buy cost across thousands of rows in the background.
OpenZoniq
Ask a plain-English question. Zoniq answers from FBAZone's own knowledge base, or runs the real calculators on your numbers.
OpenThree ways in. One answer.
You never connect a seller account. Give FBAZone numbers however you already have them.
Type it in
Price, cost, weight and dimensions. Fees are filled in from the fee tables for the category you pick.
Paste an ASIN
The ASIN Analyzer pulls what it can, labels every field as provider, cached or manual, and states its confidence.
Upload a CSV
Map your columns once, preview the rows, then run profit, ROI or fees across the whole file.
Not just numbers
Every result tells you what to do
Every analysis ends with what it means, why, the risks and a recommendation — and states where the data came from and how confident it is. Colour is never the only signal.
- What does this mean?
- Each unit sold nets $8.92 (25.5% margin, 85.0% ROI).
- Why
- Margin and ROI both clear the usual FBA targets (25% / 50%).
- Risks
- Profit becomes zero if the selling price falls below $22.59.
- What should I do?
- Keep landed cost at or below $13.44 and validate demand and competition before placing a large order.
Confidence: MEDIUM · Source: Estimated · FBA fee estimated from weight and dimensions.
