The exact software I use to run a £100K+/month Amazon UK FBA business. No affiliate-padded listicles — just what earns its monthly cost and what doesn't. Updated April 2026.
Most new sellers overspend on tools before they have any sales. Don't. Start with these three. Add the rest only when a specific bottleneck shows up.
Total cost: roughly £40-£60/month. Everything else can wait until you're consistently shipping product.
Price-history charts, sales rank tracking, product alerts, and Product Finder. Without Keepa you're guessing on every deal. The free version isn't enough — you need Power User to see sales rank history and use Product Finder.
Best for: Validating deals before buying, finding sourcing leads, tracking competitor stock movements.
What it doesn't do: Calculate ROI or live profit. Pair with SellerAmp.
Visit Keepa →Browser extension that gives you instant ROI, fees, sales velocity, IP risk, and Buy Box analysis on any Amazon page. UK-specific calculations including VAT. The cleanest interface of the deal-analysis tools.
Best for: OA and A2A — you'll use it on every product you check.
Alternative: BuyBotPro (more automation, busier interface).
Visit SellerAmp →Automated deal analysis — same job as SellerAmp but pushes harder on the "buy / don't buy" recommendation. Some sellers love the automation, others find it noisy. Try both with their trials.
Best for: Sellers who want fast yes/no calls, less manual review.
Visit BuyBotPro →Bulk reverse search — feed it a retailer's product list, get a CSV of profitable matches on Amazon. Massive time-saver once you're past the manual sourcing stage. Steep learning curve but pays back fast.
Best for: Established OA sellers doing £5K+/month who need to scale sourcing.
Avoid if: You're new — manual sourcing first to learn what good deals look like.
Visit Tactical Arbitrage →Chrome extension that overlays variation, weight, dimensions, and category data on Amazon listings. Tiny tool, huge time-saver. The Variation Viewer alone justifies the price.
Best for: Anyone sourcing on Amazon — A2A especially, but useful for OA validation too.
Visit RevSeller →Broader Amazon toolkit — keyword research, listing optimisation, competitor tracking, refund recovery. Built more for private label than arbitrage, but the refund tools are useful at scale.
Best for: Sellers who also do PL or wholesale brand management.
Skip if: You're pure OA/A2A — too much you won't use.
Visit Helium 10 →Best mobile scanner for retail arbitrage on iPhone or Android. Scans barcodes, returns Keepa-style data, calculates profit live. Connects to your InventoryLab listing flow.
Best for: Tesco, B&M, The Range, Boots clearance trips.
Visit Scoutify →Cheaper standalone scanner. Less polished than Scoutify but works well if you don't need the InventoryLab ecosystem.
Visit Profit Bandit →Listing creator, FBA shipment workflow, profit tracking. The fastest way to get product from receipt to "ready to ship to Amazon". UK sellers should pair it with Link My Books for accounting.
Best for: Anyone listing more than ~20 SKUs/week.
Visit Inventory Lab →UK-built listing and FBA prep tool. Less feature-rich than Inventory Lab but designed for UK sellers from the ground up — pricing in GBP, VAT-aware, supports Amazon UK quirks.
Visit 2D Workflow →Pulls Amazon settlement data into Xero or QuickBooks correctly — including FBA fees, VAT, refunds, and reimbursements. The single best UK Amazon accounting integration. Saves hours and prevents misclassified VAT mistakes.
Best for: Every UK Amazon seller doing more than £1K/month. Non-negotiable past £5K/month.
Visit Link My Books →UK accounting software. Pair with Link My Books for Amazon. Talk to your accountant about which plan you need — most FBA sellers can run on Standard.
Visit Xero →Custom email on your domain, Drive, Docs, Sheets. Cheap, reliable, and Sheets is where most of the operating system runs day-to-day.
Visit Google Workspace →Where the SOPs, brand-avoidance lists, supplier database, and weekly review dashboards live. The Method FBA Operating System is delivered as Notion templates.
Visit Notion →Where I hired both my admin and sourcing VAs. Filipino talent pool, English-fluent, reasonable rates. The mentoring includes the exact job descriptions and interview workflow I use.
Visit OnlineJobs.ph →Tools I get asked about constantly that I deliberately don't pay for:
Source Mogul / OAGenius — overlaps too much with Tactical Arbitrage and Keepa Product Finder. If you have those, you don't need these.
Jungle Scout — built for private label product research. Wrong tool for OA/A2A.
Sellerise / Sellerboard — useful for PL profitability tracking but Link My Books + Xero covers what arbitrage sellers need.
"AI Amazon" tools that emerged in 2025 — most of them wrap ChatGPT around Keepa data. You can do this yourself with the Keepa API and a free ChatGPT account.
The £47 Operating System includes the Notion templates, brand-avoidance lists, VA SOPs, and the exact tool configurations I use day-to-day. Tools alone aren't a system.
