SellerAmp SAS Review: Is It Worth It in 2026?

1. What Is SellerAmp SAS?

SellerAmp SAS stands for Source, Analyze, Sell. It's a Chrome extension and mobile app that Amazon FBA sellers use to evaluate products while sourcing. Open it on any product page and you get estimated profit, BSR, buy box data, IP alert flags, and fee breakdowns all in one sidebar.

I started using it when I was doing around $15,000 a month in revenue. I'm past $100K/month now and it's still open in every sourcing session. That consistency should tell you something about how central it is to the workflow.

SellerAmp is built for online arbitrage and wholesale. If you're brand new to OA and want the full picture before adding tools, start with my guide to online arbitrage on Amazon first, then come back here.

2. How SellerAmp Works as a Chrome Extension

Install SellerAmp from the Chrome Web Store and a sidebar opens automatically whenever you land on a product page. It connects to Amazon's live data and your seller account settings, then does the math without you lifting a finger.

You type in your buy cost and it immediately shows: estimated net profit in dollars, ROI percentage, BSR, estimated monthly sales, buy box price, and whether the item qualifies for Small Standard Size fulfillment. No tab-switching, no copy-pasting ASINs anywhere.

That sidebar is why OA sellers pick SellerAmp over spreadsheet-based systems. The speed is the point. I evaluate between 50 and 80 products per hour with it running. A spreadsheet-based workflow would cut that number by more than half.

3. Setting Up SellerAmp for the First Time

Setup takes about 10 minutes. Install the extension, create your SellerAmp account, then go into Settings and connect your Amazon seller account. Select your marketplace (US, UK, CA, etc.) and enter your default prep fees if you route through a prep center.

The part that trips up beginners: the default config uses Amazon's generic fee estimates, not your actual costs. Go into the fee settings and enter your real inbound shipping cost per pound and your prep center's per-unit charge. Even being off by $0.35 per unit adds up to hundreds of dollars on a 500-unit month.

Once your numbers are dialed in, every profit figure the tool shows you is actually trustworthy. Don't skip this step and then wonder why the tool feels inaccurate.

4. The Profit Calculator: How to Read the Numbers

Type a buy cost into the sidebar and SellerAmp shows you estimated profit, ROI, and net proceeds, all updated in real time as you type. My personal thresholds are $3.00 net profit minimum and 30% ROI minimum. If I see $4.80 net at 38% ROI on a $12.60 cost, I'm buying. If I see $1.10 net, I move on in two seconds.

The calculator also pulls in Amazon's current referral fee and FBA fulfillment fee for that specific ASIN. Those fees vary by category and size tier, so a one-size-fits-all percentage estimate will get you in trouble. SellerAmp uses the actual numbers.

It also flags gated categories, known IP complaint brands, and hazmat classifications right there in the sidebar. Those flags have stopped me from buying product I physically couldn't have sold. For a deeper look at the margin math side, see my post on how to use an Amazon FBA profit calculator.

5. Reading BSR and Sales Estimates

BSR (Best Sellers Rank) tells you how fast a product moves within its category. The raw number means nothing without context. A BSR of 12,000 in Home & Kitchen is very different from a BSR of 12,000 in Industrial & Scientific. SellerAmp converts the rank into an estimated number of units sold per month, which is what actually matters.

Use that sales estimate to sanity-check your buy quantity. If the estimate is 240 units per month across 8 FBA sellers, each seller averages 30 units per month. If you buy 60 units, you're looking at roughly a two-month sell-through. That changes how you think about storage fees and tied-up capital.

You also get the Keepa price history chart embedded directly in the sidebar. Before I buy anything, I check whether the current buy box price is stable or a temporary spike. For everything you need to know about that chart, read my post on reading Keepa charts as a beginner.

6. IP Alerts and Hazmat Flags: The Safety Net

SellerAmp cross-references a database of brands that frequently file intellectual property complaints against third-party Amazon sellers. If an ASIN is associated with a high-risk brand, the sidebar flags it in red before you buy anything.

I ignored those flags early in my business and picked up two IP complaints in my first year. Both required invoices from authorized distributors, which I didn't have. Both cost me time and account health. SellerAmp's IP alert system would have caught both of them.

The hazmat flag is similarly underrated. Certain batteries, aerosols, and cleaning products require special FBA handling or are outright prohibited from standard fulfillment centers. SellerAmp catches the vast majority of these automatically. It's not perfect, but it filters out the obvious problems faster than any manual check.

7. The Keepa Chart Integration

SellerAmp embeds a condensed Keepa chart directly in the sidebar. You can see buy box price history, new FBA offer history, and seller count trends without opening a separate tab or logging into Keepa independently.

The two things I look for every time: Is the buy box price stable at or above my calculated sell price? And is the seller count rising fast, which would signal that a YouTuber or deal site just featured the product?

If the buy box dropped 35% eight months ago and never recovered, that's a dead product. SellerAmp surfaces that in about five seconds. Products that look profitable based on the current price often reveal a very different story in the chart.

8. SellerAmp Mobile App: Using It for Retail Arbitrage

SellerAmp includes a mobile app for retail arbitrage. You scan a barcode in-store and get the same profit calculation, BSR data, and alert flags you see on the desktop extension. One subscription covers both.

My business is almost entirely online arbitrage, so the app isn't my primary tool. But I've used it on liquidation store runs and the speed is noticeably better than the Amazon Seller app. The fee breakdown and seller count are cleaner and the IP alert system travels with you.

If you split time between OA and RA, getting both tools in a single $19.99/month subscription is a real advantage. Most dedicated RA tools are priced separately and don't have the OA-side features.

9. SellerAmp vs ScoutX: The Free Alternative

ScoutX is a Chrome extension from InventoryLab. If you already subscribe to InventoryLab, ScoutX is free. It adds a sidebar to product pages that calculates your cost, shows fee estimates, and gives you the basic product data you need to make a sourcing decision.

"It's doing pretty much everything that SellerAmp is doing when it comes to, you know, that sidebar. It's going to help you calculate your cost, whether it is small and light and stuff. And you know, you are going to have all the information you need." SellerAmp vs ScoutX: Finally Some Competition for SellerAmp? (2023)

The honest take: if you're just starting out and already pay for InventoryLab, try ScoutX first before adding another monthly cost. It covers the basics well enough to learn the sourcing workflow. But as your volume grows, SellerAmp's IP alert system, deeper Keepa integration, and faster UI start pulling ahead. Almost every serious OA seller I know eventually lands on SellerAmp.

10. SellerAmp SAS Pricing: What You Actually Pay

SellerAmp costs around $19.99/month on the standard plan. There's a free trial, so you can run it through a real sourcing session before paying anything.

The ROI math is simple. If SellerAmp stops you from buying one bad product per month, a product you would have bought without knowing about an IP flag or a collapsing buy box, it has paid for itself. At $20/month, that's one avoided mistake. Most beginners make that mistake inside their first two weeks.

If you're still using it after 60 days, switch to the annual plan. The per-month cost drops and you'll be using it for the full year anyway. For a broader look at what software is actually worth paying for when you're starting out, see my breakdown of the best Amazon FBA tools for beginners.

11. Who SellerAmp Is Actually Built For

SellerAmp is built for online arbitrage and wholesale sellers doing product research at volume. If you're evaluating 30 or more products per day, this tool pays for itself in time savings alone. The speed difference between a sidebar tool and any manual process is not small.

It's not the right tool if you're doing private label and evaluating one product every two weeks. The profit calculator would work fine, but you wouldn't use 80% of what you're paying for.

For OA specifically, and especially if you're following a system like what I teach in The Scaling Society, SellerAmp is standard equipment from day one. My students start using it during their first sourcing session. There's no waiting until you're "ready enough" to use it.

12. My Honest Verdict: Is SellerAmp Worth It in 2026?

Yes. For online arbitrage sellers, SellerAmp is as close to a must-have tool as this business has. The profit calculator alone justifies the $19.99/month. The IP alerts, real-time fee breakdown, Keepa integration, and sales estimate on top of that make it the center of a serious sourcing workflow.

If you're an absolute beginner: start the free trial during your first 30 days of sourcing. Don't wait until you feel ready. You need to see the numbers while you're learning the decision-making process, not after.

If you want to watch me use SellerAmp in a real, live sourcing session, grab a free seat at my Thursday training. I source live every week, run every product through the same system, and show you exactly what the numbers need to look like before I buy. No slides, no theory. Just live sourcing.
