🛠️ Tools & Software

Having the right tools makes a massive difference in FBA. They help you find profitable products faster, avoid bad buys, and manage your business efficiently. Here’s a breakdown of the essential tools every seller should know about.

Product Research & Scanning

These tools help you analyse products to decide if they’re worth buying.

Keepa

What it does: Shows the complete price history, sales rank history, and Buy Box history for any product on Amazon. Essential for understanding whether a product actually sells and what price it typically goes for.

Why you need it: A product might look profitable right now, but Keepa shows you if the price is about to crash, if it only sells well at Christmas, or if the sales rank is usually much worse than today. It’s also a powerful tool for finding A2A deals — you can set up price drop alerts and track products where Amazon’s own price fluctuates, then buy low and sell at the normal price.

Advanced use: Beyond basic price checks, Keepa lets you do serious due diligence on products. You can see historical data on how many FBA sellers have been on a listing over time, how often the Buy Box rotates, seasonal trends, and whether a product’s sales rank is genuinely consistent or just had a one-off spike. This data is what separates beginners from sellers who consistently make money.

• Browser extension + website
• Free version shows basic price history
• Paid version (€19/month) shows sales rank, Buy Box %, offer count history, and much more — worth every penny

This is the #1 tool for FBA sellers. If you only pay for one tool, make it Keepa.

SellerAmp (SAS)

What it does: All-in-one product analysis tool. Shows you profit calculations, sales estimates, competition analysis, IP risk alerts, and more — all on one screen. You plug in your buy cost and it instantly shows your profit, ROI, and fees breakdown.

Why you need it: Instead of checking 5 different places to decide if a product is worth buying, SellerAmp gives you everything in one view. Crucially, it also tells you whether you’re eligible to sell that item — it checks if you’re gated for that category or brand, and shows you whether ungating requires 10 units or 100 units on the invoice. This saves you finding out the hard way after you’ve already bought stock.

• Browser extension
• Around £17/month
• Works alongside Keepa for the full picture

RevSeller

What it does: Quick profit calculator that overlays directly on Amazon product pages. Shows you estimated profit, ROI, and fees at a glance.

Why you need it: Faster than the Amazon Revenue Calculator for quick scanning. Great for when you’re browsing and want to quickly check if something is worth a deeper look.

• Browser extension
• One-time purchase (~£100 lifetime)
• Simple and effective

Sourcing Tools

These help you find deals and products to buy.

Tactical Arbitrage

What it does: Scans entire retailer websites and compares prices against Amazon. Finds products you can buy cheap and resell on Amazon at a profit.

Why you need it: Instead of manually checking every product on Boots or Argos, Tactical Arbitrage does it for you. It can scan thousands of products in minutes and flag the profitable ones.

• Web-based tool
• From around £50/month
• Steep learning curve but very powerful once set up

BuyBotPro

What it does: Analyses products and gives them a score — essentially telling you “this is a good buy” or “skip this.” Integrates with Keepa data and checks restrictions, hazmat status, and more.

Why you need it: Speeds up decision-making. Instead of manually checking every metric, BuyBotPro gives you a quick verdict.

• Browser extension
• Around £30/month

SellerToolkit

What it does: Advanced analytics and product research platform with deep data on Amazon listings, sales estimates, and profitability tracking.

Why it’s worth knowing about: SellerToolkit can backdate data, meaning you can pull historical information on products and listings that goes beyond what other tools offer. This is powerful for spotting long-term trends and making more informed sourcing decisions.

• Web-based platform
• Paid tool — various plans

Note for beginners: You don’t need SellerToolkit right away. Get comfortable with Keepa and SellerAmp first — they’ll cover everything you need starting out. SellerToolkit is one to add later when you want deeper data and more advanced analysis.

Listing & Business Management

Amazon Seller App

What it does: Amazon’s official mobile app for sellers. Check sales, manage inventory, scan products in-store (RA), and handle customer messages.

Why you need it: It’s free, it’s official, and you’ll check it constantly. The built-in scanner is handy for retail arbitrage.

• Free
• iOS and Android

Inventory Lab / SellerBoard

What it does: Tracks your actual profits, accounting, and inventory performance. Shows you real numbers after ALL costs (buy price, prep, shipping, Amazon fees, returns).

Why you need it: Amazon’s built-in reports don’t give you the full picture. These tools show you your true profit per product and overall business performance.

• SellerBoard: from ~£15/month
• Inventory Lab: from ~£50/month

Important: You need one of these or a spreadsheet system. Without tracking your actual costs, you’re guessing whether you’re making money. Many sellers THINK they’re profitable but are actually losing money once you account for returns, storage fees, and prep costs.

Free Tools You Should Know About

What Should You Get First?

If you’re just starting out, here’s the priority order:

1. Keepa (paid) — non-negotiable, you need price and rank history
2. Amazon Seller App — free, install it immediately
3. SellerAmp or RevSeller — quick profit calculations while scanning
4. A tracking method — even a simple spreadsheet to start

Don’t buy every tool on day one. Start with Keepa and a profit calculator, learn the basics, then add tools as your volume and needs grow.
