RevSeller vs SellerAmp: Which Wins for OA Sellers

1. The Short Answer

If you source OA full-time, buy SellerAmp. If you're in your first 90 days and money is tight, RevSeller gets you started. Both are Chrome extensions that overlay profit data on Amazon product pages. But they are not equal tools.

I've been running online arbitrage at scale for years and I've tested every extension in this category. Here's the honest breakdown with no fluff.

2. What SellerAmp SAS Actually Does

SellerAmp SAS stands for Source, Analyze, Ship. It's a Chrome extension that lives on Amazon product pages and on most major retail sites. Open any listing and you get a sidebar with net profit, ROI, estimated monthly sales, FBA fees, a Keepa chart, IP alert status, and hazmat flags.

The key differentiator: SellerAmp works on the retail site, not just on Amazon. You can be browsing Target, Walmart, or Walgreens and see your estimated profit before you ever click over to Amazon. That is a sourcing speed multiplier.

The mobile app is solid too. You can scan barcodes in physical retail stores and pull the same profit data. If you mix any retail arbitrage into your OA, the app alone justifies the subscription.

3. What RevSeller Actually Does

RevSeller is a Chrome extension that overlays a profit calculator on Amazon product pages. It's been around since 2018, which means a lot of OA sellers learned sourcing on RevSeller before SellerAmp even existed. The interface is a horizontal panel that appears at the bottom of Amazon listings.

You get estimated profit, ROI, a sales rank percentile, and break-even price. Type in your buy cost and it recalculates in real time. Clean and fast.

What RevSeller does not do: it doesn't work on retail sites, has no mobile app, no native Keepa chart, and no IP alert integration. You're getting one piece of the puzzle, not the full picture.

4. Profit Calculator: Head to Head

Both tools pull Amazon's fee structure and let you input a buy cost to see your net profit. The underlying math is the same. Where they differ is how accurately each tool tracks fee changes when Amazon updates its structure.

SellerAmp has been more reliable in my experience. When Amazon revised FBA fees in early 2024, SellerAmp pushed the update faster. RevSeller lagged by a few days, which means your numbers were off until they caught up.

Real example: on a product with a $34.99 buy price from Walmart, SellerAmp showed a net of $11.20 at a $52.99 sell price. RevSeller showed $11.85 on the same listing. That $0.65 gap was RevSeller missing an updated dimensional weight fee. Small per unit, but multiplied across hundreds of units it matters.

5. IP Alerts and Restriction Checking

This is where SellerAmp wins by a wide margin. SellerAmp has a built-in IP alert database. If a brand is known for filing intellectual property complaints against third-party sellers, SellerAmp flags it with a red or yellow warning right in the sidebar. You see it before you buy.

RevSeller has no IP alert feature. None. You'd need a separate tool like the IP Alert Chrome extension running alongside it to get this data. That's an extra subscription, an extra step, and one more thing to remember to check on every product.

For OA at volume, IP complaints can do real damage. One strike from the wrong brand can pull your listing or put your account at risk. Having this data built into your sourcing tool isn't optional if you're running this as a real business.

6. Keepa Integration and Price History

SellerAmp embeds a Keepa chart directly in the sidebar. You see 90-day and 365-day price and BSR history without opening a separate Keepa tab. You can also see the buy box history and how many sellers were on the listing at any given point.

RevSeller has no Keepa built in. You'd need the Keepa Chrome extension running separately. Most serious OA sellers run Keepa anyway, but it's still two clicks instead of one. Over 200 sourcing decisions per day, that adds up.

"Let's go on Amazon and let's take a random beauty product that sells at Ulta... let's open SellerAmp. It's number two - so it's actually a bad example. Amazon is probably on the listing. But let's look at something else." LIVE Amazon FBA Online Arbitrage Sellers Hangout

The embedded Keepa chart is also useful for a quick gut check on price trend direction. A product at 40% ROI that has been crashing in price for six months is a pass. SellerAmp makes that call in one look.

7. BSR Data and Estimated Monthly Sales

SellerAmp shows you the current BSR plus an estimated monthly sales figure based on that rank. The estimates aren't perfect - no tool's are - but they give you a working baseline. A product ranked 25,000 in Home and Kitchen sells very differently than one ranked 250,000.

RevSeller shows a sales rank percentile. Knowing a product is in the top 3% of its category tells you it moves, but it doesn't tell you whether it sells 30 units a month or 300. That difference matters a lot when you're deciding how many units to send in.

8. Pricing: What You Actually Pay

RevSeller costs $99.99 per year. That's $8.33 per month. There's no monthly billing option.

SellerAmp runs $17.99 per month on the monthly plan, or $14.99 per month on the annual plan ($179.88 per year). Annual is the move if you're committing to it.

SellerAmp costs roughly $80 more per year than RevSeller. If you're sourcing full-time and the IP alert feature saves you from one bad $200 purchase, it has paid for itself. If you're doing 5-10 transactions a week as a side hustle, RevSeller is a reasonable entry point.

Also worth knowing: if you already have InventoryLab, there's a free extension called ScoutX that's worth testing before you spend anything. I cover that in the next section.

9. What About ScoutX (The Free Option)?

If you're already paying for InventoryLab, you get access to ScoutX for free. It's a Chrome extension from the InventoryLab team that does product analysis in a sidebar similar to SellerAmp.

"It's a Chrome extension that does pretty much what SellerAmp is doing when it comes to calculating your cost and stuff." SellerAmp vs ScoutX | Finally Some Competition for SellerAmp?

ScoutX covers the basics: cost calculation, FBA fees, estimated sales, and small and light eligibility. No IP alerts, no mobile app, no retail site overlay. But if you're already paying for InventoryLab, run ScoutX for two weeks before paying for anything else.

My ranking: SellerAmp is the best paid option. ScoutX is the best free option. RevSeller sits in the middle at the lowest price point of the paid tools.

10. Which Tool Fits Your Current Stage?

Here's how I break it down by where you are in the business.

• First 90 days, under $2K sourcing budget: Use RevSeller. It's cheap, it works, and you're still learning the core mechanics. Don't over-build your tool stack before you know what you're doing.
• $2K-$10K monthly sourcing budget: Move to SellerAmp. You're doing enough volume that IP alerts and accurate fees pay for the extra $7 per month easily.
• Already on InventoryLab: Test ScoutX for two weeks before buying anything else. If it covers your needs, stay free.
• Scaling past $20K per month: SellerAmp is non-negotiable. You need every efficiency edge you can get, and the IP alert database protects your account at the volume that makes it vulnerable.

11. My Actual Setup

I run SellerAmp SAS as my primary sourcing tool. I pair it with Keepa for deeper chart analysis on products I'm considering buying in bulk, and I use the SellerAmp mobile app on the rare occasions I'm in a physical store.

I don't use RevSeller anymore. I moved to SellerAmp a few years back and never went back. The IP alert feature alone has flagged brands I almost bought into that would have been account-level problems at the volume I run.
