Amazon FBA wholesale product research requires fast accurate data. The difference between a profitable wholesale business and a loss-making one often comes down to how quickly and accurately you can analyse products as you source — whether that is scanning a supplier price list, browsing Amazon or scanning barcodes at a trade show. Seller Amp is one of the tools many wholesale sellers use for this fast-scan research workflow and in this guide we explain exactly what it does, how to use it and how it fits alongside the broader research stack every FBA wholesale seller needs.

We are Brandhunterz Ltd — a UK registered wholesale sourcing company (Company No: 15342697) — and our product research process combines multiple tools to give us the most complete and reliable picture of any wholesale opportunity before we commit any capital.

What is Seller Amp?

Seller Amp (also referred to as SAS — Seller Amp SAS) is a product research tool for Amazon FBA sellers available as both a smartphone app and a Chrome browser extension. It is designed primarily for wholesale and arbitrage sellers who need to quickly evaluate large numbers of products — whether scanning barcodes at trade shows with their phone, analysing supplier price lists through the Chrome extension or browsing Amazon for wholesale opportunities.

The core value of Seller Amp is speed. It gives you instant access to the data points most relevant to a wholesale buying decision — profitability, sales rank, Buy Box status, restriction status and competition level — without needing to manually check multiple sources.

Feature	What It Shows You	Why It Matters for Wholesale
Profit Calculator	Net profit and ROI after all Amazon fees	Instant margin check on any product
Sales Rank	Current BSR and category rank	Quick demand indicator
Buy Box Data	Current Buy Box price and winner	Tells you who controls the listing
Restriction Check	Whether you can sell this product	Prevents ordering ungatable products
Seller Count	Number of FBA sellers on listing	Competition level assessment
Amazon on Listing	Whether Amazon sells this product	Critical Buy Box access indicator
Variation Viewer	All product variations with BSR and price	Find best-performing variants to order

How Seller Amp Works — The Two Access Points

Access Point 1 — The Mobile App

The Seller Amp mobile app is available for both iOS and Android. It allows you to scan product barcodes using your phone camera and instantly see all the key data for that product on the Amazon marketplace. This makes it particularly powerful at trade shows where you can walk around scanning products on display and immediately see whether they are worth pursuing a wholesale account for — without needing to sit down at a laptop or manually search each product on Amazon.

The app also allows you to enter a product cost price and instantly calculate your net profit and ROI after Amazon fees — giving you a complete profitability picture in seconds. You can save products to a list during your trade show visit and review them later with deeper analysis tools like Keepa and Helium 10.

Access Point 2 — The Chrome Extension

The Seller Amp Chrome extension displays a data panel directly on any Amazon product page as you browse — showing all the key wholesale research data points without needing to navigate to a separate tool. When analysing supplier price lists you can search for each product on Amazon and immediately see the Seller Amp data overlay showing profit, sales rank, Buy Box status and restriction information.

The Chrome extension also works on supplier websites — clicking on a product image will attempt to identify the matching Amazon listing automatically saving significant research time when working through large supplier catalogues.

Setting Up Seller Amp for Wholesale Research

Reading the Seller Amp Data Panel

When you open the Seller Amp panel on any Amazon product listing you see a structured display of the key data points. Here is how to interpret each one for wholesale buying decisions:

The Profit Calculator Section

Enter your wholesale buy price in the Buy Cost field and Seller Amp instantly calculates your net profit and ROI after deducting Amazon referral fee, FBA fulfilment fee and any additional costs you have configured. The result shows your margin at the current Buy Box price — the most realistic selling price for a wholesale seller entering the listing.

The Sales Rank and History Section

Seller Amp displays the current BSR and if you have connected your Keepa API key it shows a compact sales history chart alongside the current rank. The 30-day, 90-day and 180-day average BSR figures give you a more reliable picture of typical sales velocity than the current rank alone — which can fluctuate significantly hour to hour.

For any product that passes the green light stage in Seller Amp always open the full Keepa chart separately and review 12 months of complete data. Seller Amp’s built-in Keepa widget shows only a summary — the full chart reveals seasonal patterns, price history and long-term consistency that the summary alone cannot confirm.

The Variation Viewer

For products with multiple variations — different sizes, colours or pack quantities — the Seller Amp variation viewer displays each variation with its individual BSR, price and FBA fee. This is particularly valuable for wholesale research because it allows you to identify which specific variants sell best rather than ordering all variations equally. Often one or two variants account for the majority of sales on a listing and targeting those specifically optimises your inventory investment.

Using Seller Amp for Price List Analysis

One of the most valuable workflows for wholesale sellers is using Seller Amp to analyse supplier price lists quickly. When a brand sends you their trade catalogue you typically have a list of dozens or hundreds of products with wholesale prices. Without a fast analysis tool this becomes extremely time consuming to evaluate manually.

Seller Amp at Trade Shows

Trade shows are one of the most productive environments for using Seller Amp’s mobile app. Walking around a trade show with thousands of products on display scanning barcodes with your phone and instantly seeing profitability data gives you a significant advantage over buyers who are taking notes to research later.

Trade Show Workflow Step	Action
At each stand	Scan products with Seller Amp — 30 seconds per product
Green products	Save to list — collect brand trade card and price list
Red products	Move on immediately — no time wasted
After the show	Run Keepa 12-month check on all saved green products
Shortlisted products	Contact brands for wholesale application

The Complete Wholesale Research Tool Stack

Seller Amp is a powerful tool for fast first-pass product screening but it works best as part of a complete wholesale research stack rather than as a standalone solution. Here is how all the tools fit together:

Tool	Role in Research Stack	When to Use
Seller Amp	Fast first-pass scan and profit check	Price list analysis and trade shows
Keepa	12-month sales history verification	Every product passing Seller Amp filter
AMZScout	Independent margin and sales estimate	Final validation before ordering
Helium 10	Keyword research and listing analysis	Evaluating listing quality and search demand
Zik Analytics	eBay channel sell-through research	Assessing eBay opportunity alongside Amazon

Seller Amp Limitations to Know

Understanding what Seller Amp cannot do is as important as knowing what it can do. There are specific limitations that make it essential to use alongside other tools rather than relying on it alone:

Limitation	Why It Matters	Solution
No full price history	Cannot identify price wars or downward trends	Always check full Keepa chart
Current BSR only	Current rank may not reflect typical performance	Use Keepa 30, 90, 180 day average BSR
No keyword data	Cannot assess listing search visibility	Use Helium 10 for keyword analysis
No eBay research	Cannot evaluate second channel potential	Use Zik Analytics for eBay data
Sales estimate only approximate	Monthly sales estimates can vary from reality	Cross-validate with AMZScout

Conclusion — Seller Amp as Part of a Smarter Research System

Seller Amp is a genuinely useful fast-scan tool for Amazon FBA wholesale sellers — particularly for trade show scanning and first-pass price list analysis where speed is the priority. It eliminates the obvious non-starters in seconds and highlights the products worth taking to deeper analysis.

However it should never be used as the sole basis for a wholesale buying decision. Every product that passes the Seller Amp first-pass filter must be validated with 12 months of Keepa data before ordering. Final margin calculations should be cross-validated with AMZScout or Helium 10 and any wholesale products you plan to sell on eBay alongside Amazon should be validated with Zik Analytics.

This complete research system — Seller Amp for speed, Keepa for history, AMZScout or Helium 10 for validation and Zik Analytics for eBay — is what separates sellers who make confident profitable wholesale buying decisions from those who guess and hope for the best.
