Brand Analysis Tools: Essential for Finding Reliable Suppliers
Brand research is a critical step in building a successful online arbitrage strategy. Not all brands make good suppliers. Some offer too few products, limiting the chances of finding profitable deals. Others are dominated by Amazon, making it hard for resellers to compete and win the Buy Box. For these reasons, analyzing brands before sourcing from them – especially when parsing their websites and scanning product lists – is a must.
This is where Seller Assistant’s Brand Analyzer becomes invaluable. It automates brand research, helping sellers quickly identify which brands are resale-friendly and offer real opportunities.
Brand Analyzer: Streamline Amazon Brand Research
Seller Assistant's Brand Analyzer is a dedicated Amazon brand research tool that helps sellers quickly identify profitable and resale-friendly brands.

Why use Brand Analyzer
Choosing the right brands to partner with can make or break your sourcing efforts.

Competitor Analysis Tools: Monitor Competitors for New Deals
Understanding what your competitors are doing is key to staying ahead in Amazon’s dynamic marketplace. With competitor analysis tools, sellers can monitor rival storefronts to discover their best-selling products, avoid items they have stopped selling, and even adjust pricing based on market trends. This allows sellers to replicate proven successes, fill gaps in their catalog, and ensure their prices remain competitive over time.
Seller Assistant’s Seller Spy makes competitor research simple and automatic, giving sellers deep insights into how their rivals operate and helping them make smarter selling decisions.
Seller Spy: simplify competitor analysis for Amazon sellers
Seller Spy automates competitor tracking, providing Amazon sellers with essential data to stay one step ahead. It monitors competitor activities, helping identify new brands and products they have started or stopped selling, as well as tracking their pricing strategies.

Price

VPN Tools: Access Restricted Supplier Sites
A reliable VPN is essential for Amazon online arbitrage sellers. Many supplier websites block access based on location, which can prevent sellers from browsing or placing orders. Additionally, product prices may vary depending on your IP address – often showing higher prices to visitors from regions like the United States. Without a VPN, you risk missing out on profitable deals or being overcharged.
VPN Extension by Seller Assistant solves these issues with a seamless Chrome-based solution designed specifically for Amazon sellers. Integrated directly into Seller Assistant’s sourcing software, it bypasses geo-restrictions, protects privacy, and eliminates the need to purchase separate VPN tools.
VPN Extension: unlock supplier sites and view local prices
VPN Extension by Seller Assistant is built to help sellers access supplier websites, retailer platforms, and online resources without regional limitations. Whether you're dealing with blocked websites or need to compare prices from different markets, this tool makes advanced product research easy and secure.
Fully integrated into Seller Assistant, this VPN extension allows sellers to browse globally while maintaining secure connections – without the need for external VPN subscriptions or complicated setups.
Why use the VPN Extension
Geo-restrictions and location-based pricing can block or limit access to supplier offers. The VPN extension helps sellers overcome these issues, enabling unrestricted browsing and ensuring access to local prices anywhere in the world – all from within Seller Assistant.
Key features and functionality
- Bypass geo-restrictions
Unblock supplier websites and explore full product catalogs and local prices, regardless of your physical location.

Price
VPN Extension is one of 20+ Seller Assistant’s tools. Seller Assistant subscription starts from $29.99/month.
IP Alert Tools: Protect Your Account from IP Complaints
Intellectual property (IP) complaints are one of the most serious threats Amazon sellers face. Brands can file IP complaints if they believe a product violates their trademarks, copyrights, or other intellectual property rights. Amazon takes these complaints very seriously – receiving them can result in listing removals, account suspensions, or even permanent bans.
Because of this, sellers must carefully check products for any history of IP complaints or Amazon policy violations before listing them. Proactive IP monitoring helps avoid risky products that could jeopardize your seller account.
IP Alert Extension: protect your account from risky products
Seller Assistant’s IP Alert® Extension is a powerful solution designed to identify and warn sellers about products and brands with intellectual property issues. Connected to Seller Assistant’s exclusive database of Amazon policy violations, this extension delivers instant alerts whenever a product has a history of IP complaints or other violations.
Integrated seamlessly into Amazon product pages, search pages, supplier websites, and competitor storefronts, IP Alert is an essential part of any seller’s product research process. It ensures you always know when a product carries hidden risks.
Why use IP alert extension
Amazon’s strict enforcement of intellectual property rules makes selling risky products dangerous. IP Alert removes the guesswork by instantly notifying you about problematic products and brands. This helps protect your account, save time, and avoid costly mistakes before they happen.

Price
IP Alert Extension is one of 20+ Seller Assistant’s tools. Seller Assistant subscription starts from $29.99/month.
Restriction Checker Tools: Verify Selling Eligibility Before Buying
Before sourcing any product, Amazon sellers must ensure they are eligible to sell it. Some products and brands are restricted, requiring prior approval to list, while others may be entirely blocked based on account status or selling history. Approval is not guaranteed, so buying restricted products without checking eligibility can lead to costly mistakes and unsellable inventory.
That’s why verifying product restrictions before making purchasing decisions is essential. Seller Assistant’s Bulk Restriction Checker makes this process fast and easy, helping sellers confirm their eligibility across multiple products at once.
Bulk Restriction Checker: verify selling eligibility at scale
Seller Assistant’s Bulk Restriction Checker is a must-have tool that simplifies the process of verifying product and brand restrictions in bulk. Instead of checking each ASIN manually, sellers can upload product lists and instantly see which items are restricted, require approval, or are eligible for sale.
This powerful solution helps sellers avoid mistakes, stay compliant with Amazon’s policies, and focus only on sourcing products that they are allowed to sell.
Why use Bulk Restriction Checker
Amazon’s complex restriction rules make manual eligibility checks tedious and risky. Bulk Restriction Checker automates this process, saving time and reducing errors. Sellers can quickly determine which products are ungated, gated, or entirely impossible to sell on your account before making purchasing decisions.
Key features and functionality
- Selling eligibility verification

- Red closed lock with exclamation mark: Not eligible for sale.
Price
Bulk Restriction Checker is one of 20+ Seller Assistant’s tools. Seller Assistant subscription starts from $29.99/month.
Price Tracker Tools: Monitor Pricing Sales History
Price tracking tools are essential for Amazon sellers looking to understand long-term product behavior. These tools don’t just show current prices – they track price history, Buy Box behavior, and sales trends over time. This helps sellers evaluate whether a product is consistently profitable or if pricing fluctuates too much to be reliable.
Advanced tools like Keepa offer far more than just price charts. They provide detailed product performance data, including sales rank history, Buy Box trends, offer count changes, and stock level tracking. This makes them invaluable for verifying product stability, forecasting demand, and choosing deals with predictable returns.
