In short: SellerMagnet is an all-in-one Amazon reseller platform that reprices every 5 minutes to win the Buy Box, tracks per-SKU profit with all fees included, sends real-time low-stock and Buy Box loss alerts, and helps you find profitable products to source, so you spend less time on spreadsheets and more time scaling your business.
As an Amazon reseller, whether you're running retail arbitrage, wholesale, or a mix of both, you know the marketplace never sleeps. Competitors reprice around the clock, the Buy Box shuffles every few minutes, and one wrong pricing decision can wipe out your margin on an entire shipment. SellerMagnet gives resellers a single, integrated platform that automates the hard work (pricing, analytics, sourcing, and alerts), so you can focus on what matters: growing a profitable business.
Repricing every 5 min. Stay competitive 24/7 automatically.
Per-SKU P&L. All fees included. No surprises.
Real-time alerts. Buy Box lost, stock low, margins at risk.
Product Sourcer. Find profitable ASINs instantly.
The Challenges Amazon Resellers Face in the Marketplace
Competing Constantly for the Buy Box on Crowded Listings
When multiple resellers list the same ASIN, the Buy Box becomes the single most important factor in generating sales. Prices shift by the minute, and a manual pricing approach simply can't keep up. Missing the Buy Box, even for a few hours, means missed revenue that goes directly to your competitors.
Key fact: Over 80% of Amazon sales go through the Buy Box. If you're not in it, you're virtually invisible.
Maintaining Positive Margins on Every Product
Between Amazon referral fees, FBA fulfillment costs, inbound shipping, returns processing, and constant downward pricing pressure, it's frighteningly easy to sell at a loss without realizing it. Resellers need real-time visibility into costs and revenue per product, not end-of-month spreadsheet surprises.
Managing Hundreds of ASINs and Stock Rotation
An arbitrage or wholesale reseller may carry hundreds of unique products across multiple warehouses and marketplaces. Keeping track of inventory levels, ensuring fast-selling items are always in stock, and clearing slow-moving items before long-term storage fees bite is a constant juggling act.
Continuously Finding Profitable Products to Resell
The reseller model demands an ongoing pipeline of profitable items. Without accurate data on sales velocity, competition density, fees, and potential ROI, sourcing becomes guesswork. Every bad sourcing decision ties up capital in inventory that may never sell at a profit.
How SellerMagnet Supports Resellers (Problem → Solution)
Automatic Repricing to Win the Buy Box
Problem: Manual pricing adjustments can't keep pace with competitors who are repricing around the clock. By the time you update a price, the opportunity has already passed.
Solution: The SellerMagnet Repricer updates your prices every 5 minutes based on competitor moves and your custom rules. Choose dedicated strategies (Buy Box targeting, lowest price, or margin-first) and set min/max price guardrails to ensure you never trigger a race to the bottom. More Buy Box wins, no margin sacrificed.
Real-Time Per-SKU Margin Monitoring
Problem: It's incredibly difficult to know the true profit on each product when you factor in referral fees, FBA costs, shipping, VAT, and returns. Margins can erode silently.
Solution: SellerMagnet's Analytics Dashboard tracks revenue, commissions, FBA shipping costs, VAT, and returns for every ASIN. You finally get accurate P&L per SKU and per marketplace, instantly spotting loss-making items and hidden margin leaks.
Efficient Inventory & Stock Rotation Management
Problem: With dozens of orders a day across many products, stock-outs or dormant inventory are constant threats. Running out of stock kills your Buy Box share and organic ranking.
Solution: SellerMagnet provides low-stock alerts and multi-warehouse monitoring. Receive notifications before an item runs out so you can reorder in time. By cross-referencing sales velocity with current stock, you can launch targeted markdowns (via the Repricer) to accelerate rotation of stale inventory before storage fees eat into profits.
Data-Driven Product Sourcing
Problem: Choosing what to resell takes time and carries real risk without reliable data on demand, competition, and fees. A wrong call ties up capital in unsellable inventory.
Solution: The integrated Amazon Product Sourcer lets you analyze any ASIN: estimated sales volume, number of competing sellers, fee breakdown, and potential ROI. With the Chrome extension you can evaluate opportunities while browsing Amazon, rapidly identifying the most profitable products to add to your catalog.

What Amazon Resellers Say About SellerMagnet
“Since switching to SellerMagnet our Buy Box share went from 38% to 67% in the first month. The 5-minute repricing cycles keep us ahead of competitors without us touching a single price manually.”
Marco R.
Wholesale Reseller • 320+ ASINs • Amazon DE
“The Dashboard finally showed me I was losing money on 14 SKUs I thought were profitable. Once I set min-price floors, my overall margin jumped 19%. I can't imagine going back to spreadsheets.”
Sarah K.
Arbitrage Reseller • 180 ASINs • Amazon US
“Managing 500 SKUs across DE, IT and FR used to take our team 3 full days a week. With SellerMagnet we cut that to half a day. The low-stock alerts alone saved us from at least 4 stock-outs last quarter.”

Amazon Reseller Tools: Frequently Asked Questions
Yes, SellerMagnet is specifically designed to increase your Buy Box win rate. The automatic repricer reacts faster than any manual adjustment: it keeps your price competitive within the limits you set. The system also sends instant alerts if you lose the Buy Box on a product, so you can act promptly (e.g., adjust strategy or check account health). Many resellers report a higher Buy Box share after implementing SellerMagnet, because the tool keeps them one step ahead of competitors, aligning with Amazon’s Featured Offer eligibility criteria.
Absolutely, the platform is built for scalability. You can import your SKU list in bulk (e.g., via CSV) and apply repricing rules to groups of products in a single step. The Dashboard lets you filter and sort products by performance, category, marketplace, etc., giving you a clear view even with very large catalogs. Whether you manage 20 or 500 ASINs, SellerMagnet keeps operations equally agile.
SellerMagnet protects you on two fronts: analysis and automation. On the analysis side, the Dashboard calculates the net margin for every order and product, including all expenses (Amazon commissions, shipping costs, VAT, etc.), so you spot unprofitable items immediately. On the automation side, the Repricer lets you set a minimum price based on your purchase cost and desired margin: the system will never go below that threshold. You can also enable margin alerts: if a price drops enough to erode your profit, you'll be notified immediately.
Yes, the platform fully supports both Amazon FBA (Fulfillment by Amazon) and FBM (Fulfillment by Merchant) sellers. For example, the repricer accounts for shipping cost differences: for FBM you can include shipping expenses in the competitive price calculation, while for FBA you already have the Prime advantage. Similarly, the Dashboard aggregates data from both Amazon-fulfilled and self-shipped orders, giving you a complete performance picture.
Yes, SellerMagnet includes a Product Sourcer designed for product research. Enter an ASIN (or use our Chrome extension while browsing Amazon) and instantly get crucial information: estimated sales volume, competition level, Amazon fees, and potential ROI. It gives you an instant profitability analysis of any product, helping you quickly decide whether an item is worth the investment. No manual cross-referencing needed.
SellerMagnet's Amazon Alerts system covers various critical scenarios for resellers. You'll receive immediate notifications when, for example: you lose the Buy Box on an ASIN you're selling; a product is about to go out of stock (low inventory level); there are unusual price changes on a listing; or Amazon modifies commissions or rules that impact your costs. These real-time alerts let you react immediately, e.g., avoiding stock-outs with a timely reorder, or adjusting pricing strategy if a competitor makes an aggressive price cut.
