If you want to scale smarter and source faster, this guide is your starting point.

• Unified workflows – no switching tabs or juggling multiple apps
• Powerful team access: separate VA logins, permissions, and tracking
• Real-time sourcing decisions with full risk and profit context

Weaknesses

• No mobile app: Seller Assistant is desktop-first and doesn’t support barcode scanning for retail arbitrage sellers who rely on smartphones.
• Not beginner-focused: With 20+ features and three extensions, new or low-volume sellers may feel overwhelmed without guidance or training.
• Requires ChatGPT login for Sourcing AI: To use Sourcing AI, users must have a ChatGPT account, which may feel like an extra step for those expecting everything to be self-contained.

Final verdict

Seller Assistant is the only tool in this comparison designed to support every major sourcing workflow – from spreadsheet-based wholesale leads to live OA research and dropshipping. It offers unmatched depth with AI sourcing, risk detection, and team collaboration. If you want to go beyond checking ROI and build a scalable sourcing engine, this is your tool.

SellerAmp SAS

Tool description

SellerAmp SAS is an Amazon single-product research tool focused on retail and online arbitrage. It runs as a Chrome extension and mobile app, delivering fast, at-a-glance data like ROI, profit, sales rank, and competition – directly on Amazon listings or while scanning barcodes in-store.

Its mobile-first design and clean UI make it especially appealing to retail arbitrage (RA) sellers who need quick answers, fast calculations, and a compact toolset for on-the-go decision-making.

What SellerAmp can do

SellerAmp is best suited for sellers who value speed and simplicity. Its core capabilities include:

• Mobile app with barcode scanner: Ideal for in-store retail arbitrage. Scan any item’s barcode and instantly see profitability, BSR, restrictions, and fees.
• Amazon product page overlay: Displays ROI, profit, fee breakdowns, competition, and alerts directly on product pages.
• Inline restriction checker: Checks whether a product is gated, hazmat, or meltable directly on the listing.
• Basic competitor and offer breakdown: Shows FBA/FBM status, seller counts, and estimated stock levels.
• Sales estimates and pricing insights: Offers BSR-based sales estimates and access to Keepa charts for price history and demand trends.
• Google Sheets export: Saves leads and product data to Sheets for manual filtering or tracking.

While it lacks bulk tools, supplier discovery, or automation capabilities, it’s great for fast decisions on individual products – particularly for new or solo sellers working with limited sourcing volumes.

Best for

• Retail arbitrage sellers scanning products in physical stores
• Beginners doing one-by-one product research
• Solo sellers who prefer a simple, mobile-friendly experience
• Sellers who don’t need spreadsheets, AI, or team workflows

Strengths

• Clean mobile app with live scanning
• Fast profitability calculator
• Inline restriction checks with visual cues
• Affordable and lightweight for entry-level sellers
• Integrates Keepa for sales and price history

Weaknesses

• No bulk tools (e.g., can’t analyze price lists or spreadsheets)
• No IP alert database – flagged listings often go unnoticed
• No team support, roles, or VPN access
• No competitor/storefront analytics beyond basic FBA/FBM
• No supplier discovery or sourcing AI
• No automation or workflow integration (e.g., Zapier)

Feature comparison table

Final verdict

SellerAmp is a well-optimized tool for retail arbitrage and beginner sellers who don’t need sourcing depth, AI, or team collaboration. It offers a solid mobile experience and essential product checks for quick, in-store decisions. However, it’s not suited for scaling operations, bulk sourcing, or sellers who need brand/supplier visibility, risk detection, or automation.

RevSeller

Tool description

RevSeller is a lightweight Amazon browser extension that overlays essential profitability data directly on Amazon product pages. Designed for simplicity, it provides a quick snapshot of break-even prices, FBA/FBM calculations, and selling eligibility – all visible without leaving the page. It appeals to beginner or low-volume sellers who want a fast, no-frills way to check if a product is worth selling.

However, RevSeller’s utility ends at basic calculations. It doesn’t support bulk research, competitive insights, or automation, and lacks IP warnings and brand-level metrics. It's best seen as a starter tool, not a full research system.

What RevSeller can do

Revseller is built for on-the-spot analysis of individual Amazon products. It’s centered around providing detailed profitability and product performance data right where sellers need it most. Here’s what’s included:

• In-depth product insights on Amazon listings – Instantly displays current ROI, margins, fees, and profitability figures directly on the product page.
• Variation Viewer – Highlights which product versions (size, color, etc.) perform best based on BSR, customer ratings, and pricing.
• Price and stock history tracking – Integrated access to Keepa and CamelCamelCamel reveals pricing behavior, Amazon stock patterns, and sales velocity over time.
• Competitor Storefront View – Allows sellers to analyze what products rivals are selling and how they’re pricing them.
• Search page widget – Quickly reveals key data (restrictions, ROI, pricing) on search results pages for fast screening of potential products.
• Side Panel overlay – Lets users access essential product details without navigating away from the page.
• Smart profit calculator – Includes customizable variables like discounts, taxes, storage fees, and peak season costs to fine-tune projections.
• Bulk ASIN lookup – Uploads lists of up to 500 ASINs to retrieve essential data, although it doesn’t support UPCs or automation features.
• Google Sheets export – Lets users store researched products in spreadsheets for easier tracking and follow-up.
• While Revseller delivers solid one-by-one analysis tools, it doesn’t offer bulk processing, team-based features, or automation, making it better suited for solo sellers focused on individual product sourcing.

Best for

• New Amazon sellers
• Retail arbitrage beginners
• Sellers who only need basic product-page overlays

Strengths

• Simple to install and use
• Real-time ROI and breakeven metrics on Amazon listings
• Fast restriction check built into the overlay
• One-time payment pricing available (rare among research tools)

Weaknesses

• No bulk analysis or spreadsheet parsing
• Lacks IP alert system, risk filters, and branding insights
• No data enrichment, team features, or external integrations
• Can’t analyze supplier lists, storefronts, or variations.

Side-by-side feature table

Final verdict

RevSeller is ideal for newcomers who want to test the waters with a low-cost, easy-to-use profitability calculator. But it’s not built for scale, team use, or deeper research workflows. It lacks the tools necessary to confidently source at volume or protect your account from risk. As soon as sellers move beyond individual listing checks, Seller Assistant becomes the far superior choice – with 10x the depth, breadth, and automation.

Scan Unlimited

Tool description

Scan Unlimited is a cloud-based wholesale analysis tool designed to help Amazon sellers evaluate supplier price lists. Users upload CSV files, and the platform scans them against Amazon’s catalog to identify potential matches, calculate profit, and flag products worth considering. It’s best for sellers who primarily work with spreadsheets and want an automated way to process bulk data.

However, Scan Unlimited is limited to list scanning. It does not offer any tools for live product research, competitor analysis, IP risk detection, or brand evaluation. Its simplicity is useful – but only for sellers who handle sourcing manually, one spreadsheet at a time.

What it can do

Scan Unlimited is built to handle large-scale product research via spreadsheet uploads, streamlining the sourcing process for high-volume Amazon sellers. Here’s a breakdown of its key functionalities:

• High-volume list scanner – Efficiently scans wholesale files containing thousands of product entries, enriching each ASIN with detailed profitability metrics, including ROI, VAT considerations, pricing data, and long-term performance trends.
• Automated listing association – Links your supplier data to Amazon catalog entries using ASINs, UPCs, or titles, and returns relevant details such as brand name, item category, condition status, and Amazon fees (FBA and referral).
• Sales rank insights – Provides a real-time look at Best Seller Rank along with average BSR over 30, 90, and 180-day periods, helping sellers estimate demand consistency and sales velocity.
• Variation breakdown – Lists available product variants (like size, color, and style), although it doesn’t highlight which versions are top performers based on customer ratings or volume.
• Product info window – Lets you dig deeper into individual listings after scanning by displaying pricing history, estimated sales volume, offer-level breakdowns, and a built-in return calculator.
• Risk flagging system – Detects products with potential hazards or intellectual property concerns, alerting you to listings that may carry compliance risks or Amazon policy violations.
• Flexible profit calculation – Calculates profitability based on current sales price, shipping fees, and VAT, with the ability to input manual discounts for more tailored forecasting.
• Multipack configuration – Supports bundled product scenarios by adjusting profitability calculations to reflect multipack pricing logic.
• Offer snapshot – Shows active sellers on a listing along with their prices, condition, fulfillment channel (FBA or FBM), and seller feedback—although inventory counts are not provided.
• Historical charting – Integrated static Keepa charts display pricing and BSR movements over 30, 90, and 365-day ranges to spot trends or anomalies.
• Spreadsheet-style dashboard – The platform runs entirely in-browser, with a clean interface and Excel-style filtering tools that make sorting and analyzing leads intuitive and efficient.
• Daily Picks feature – For premium users, this tool delivers six curated product suggestions each day, complete with foundational metrics—ideal for new sellers or those working without supplier lists.
• While it excels at spreadsheet-driven sourcing, Scan Unlimited does not provide features like restriction or eligibility checks, in-browser Amazon overlays, advanced brand research, or tools for supplier site analysis. Its scope is intentionally narrow, making it strong for bulk scans but limited for broader product research needs.

Best for

• Wholesale sellers working with supplier CSVs
• Sellers looking for an automated way to evaluate price lists
• Users who don’t need IP or restriction data in-platform

Strengths

• Efficient CSV upload and bulk ASIN matching
• Basic profit analysis with ROI and margin indicators
• Keepa integration for historical data
• Clean, cloud-based interface with fast file processing

Weaknesses

• No IP alert system or restriction checker
• Doesn’t support storefront or competitor research
• Lacks variation insights, bundles/multipack flags, or advanced filters
• Not built for teams, automation, or VA workflows

Side-by-side feature table

Final verdict

Scan Unlimited is a single-function tool that works well for analyzing wholesale spreadsheets – but that’s where it ends. If your sourcing strategy includes compliance checks, brand validation, or any live product or storefront research, you’ll quickly hit its limits. Seller Assistant replicates everything Scan Unlimited offers, then expands far beyond it – adding automation, team access, risk alerts, AI-powered sourcing, and live overlays. For sellers serious about scaling and staying safe, Seller Assistant is the more advanced and flexible choice.

Analyzer.Tools

Tool description

Analyzer.Tools is a basic wholesale product analysis platform that allows sellers to upload CSV files from suppliers and match them with Amazon listings. It offers core data such as ASINs, ROI, sales rank, and estimated profit. Like Scan Unlimited, it serves sellers who rely heavily on supplier spreadsheets and prefer a simple, web-based interface.

However, Analyzer.Tools lacks key sourcing and compliance features. There are no IP alerts, restriction checks, competitor tools, or automation options. It functions strictly as a data viewer – not a decision-making engine. Its lack of depth and flexibility makes it unsuitable for sellers managing risk or scaling operations.

What it can do

Analyzer.Tools is built to streamline bulk analysis for Amazon wholesale sellers working from supplier spreadsheets. It offers a robust feature set tailored to data-driven decision-making:

• Bulk List Scanning – Uploads large Excel or CSV files and maps product listings to ASINs, delivering over 75 data points per item, including ROI, fees, price history, and rank trends.
• Bundle & Multipack Evaluation – Supports multipack listings with precise profit breakdowns for product sets and variation kits.
• Historical Metrics Overview – Tracks long-term trends across Buy Box prices, sales ranks, and Amazon stocking activity with 30/90/180-day snapshots.
• Brand Filtering – Use a built-in brand blocklist to remove specific suppliers or problematic brands from your scan results automatically.
• Competitor Storefront Extraction – Pulls complete seller inventories from any Amazon storefront to enable spreadsheet-based reverse sourcing.
• Browser-Based Reverse Sourcing – Lets users explore Amazon manually and collect promising ASINs for further evaluation.
• Amazon Business Product Suggestions – Accesses Amazon’s internal B2B opportunity engine to highlight potential high-volume product leads.
• Basic Risk Warnings – Flags listings tied to hazmat classification or brands known for issuing IP complaints.
• Favorites & Smart Filters – Lets sellers create filtered shortlists and customized views to focus on high-potential deals faster.
• While it delivers strong performance for spreadsheet-heavy workflows, Analyzer.Tools lacks features for in-browser in-depth product research to verify deals, live restriction checks, team collaboration, and online arbitrage or dropshipping use cases.

Best for

• Sellers who only scan wholesale CSV files
• Users looking for a basic online ASIN matcher
• Sellers who manually verify risk and eligibility outside the tool

Strengths

• Fast CSV processing and ASIN matching
• Provides basic profitability metrics (ROI, margin, sales rank)
• Clean dashboard with easy exports
• Useful for narrow wholesale-only workflows

Weaknesses

• No IP complaint visibility or brand restriction checks
• Lacks sales history, price trends, and Buy Box tracking
• Doesn’t offer storefront, brand, or competitor analysis
• Not built for team use, automation, or sourcing strategy

Side-by-side feature table

Final verdict

Analyzer.Tools is a bulk data viewer, not a sourcing engine. It identifies ASINs and gives basic profit indicators – but fails to help you validate or safeguard those leads. If you're relying on manual processes to check IP risk, restriction status, or brand competitiveness, you're adding hours to every decision. Seller Assistant replaces Analyzer.Tools entirely – offering deeper data, integrated compliance checks, advanced filtering, and full research workflows. For serious sellers, it's not just a better option – it’s a necessary upgrade.

Final Thoughts

In the evolving world of Amazon FBA, the right research tool isn’t just a convenience – it’s a competitive edge. This Amazon research tools comparison shows that while tools like SellerAmp, RevSeller, Scan Unlimited, and Analyzer.Tools each serve specific roles, only Seller Assistant delivers a unified platform that supports wholesale, online arbitrage, and dropshipping sellers at every stage.

With built-in sourcing AI, IP and restriction alerts, brand and competitor analysis, bulk list scanning, and even a seller-specific VPN, Seller Assistant replaces 4–5 tools with one powerful system. If you're serious about sourcing profitably, scaling operations, and reducing risk in 2025, Seller Assistant isn’t just the best choice – it’s the strategic one.
