What are the best Amazon FBA tools for UK sellers?

The UK Amazon FBA tools landscape in 2026 has consolidated around a small core that's genuinely worth paying for, plus a few essential free tools. Most "FBA software" you see advertised is bloat or US-centric — UK sellers need a tighter stack.

The essential paid tools

Keepa (~£15-£40/month depending on tier) — non-negotiable. Shows price history, sales rank history, buy-box ownership history for every Amazon ASIN. You cannot make sourcing decisions without it. Get the paid tier; the free tier has too many gaps. SellerAmp SAS (~£20/month) — fast in-store and online scanning. Pulls Keepa data + estimated profit + competition warnings inline. The mobile app is worth the cost alone for retail arbitrage. Alternative: BuyBotPro (similar concept, slightly different UX). Inner Circle FBA membership (£29.99/month Leads tier, £59.99 Mentorship) — daily UK-specific leads, 24/7 retailer monitors, founder access. Replaces the time you'd spend manually scanning yourself, and the wholesale-leads channel pays for the membership many times over for active sellers.

Free essentials

Amazon Seller app — basic but free; live scan in-store, restrictions check, instant fee estimate. Bookmark it. Our UK FBA fee calculator at /fba-fee-calculator — live Amazon SP-API data, both VAT-registered AND non-VAT-registered scenarios. No signup, free forever. Our UK BSR sales calculator at /bsr-calculator — estimate monthly sales from BSR across 33 UK categories. Free. Our bulk catalogue scanner at /catalog-scanner — upload CSV/Excel of ASINs, get live profit per row. Free for 30 ASINs/scan, more for paid members. Google Sheets — track unit economics, returns, monthly profit. Don't buy fancy "FBA accounting software" until your turnover is £100k+. Sheets is enough.

Tools that aren't worth it for UK sellers

Helium 10 / Jungle Scout / AMZScout — built for Amazon US private-label, overkill and expensive for UK arbitrage/wholesale. The keyword and PPC tools don't apply to reselling existing brands. Skip these unless you're going into private label — and even then, see if the included Keepa data covers what you actually need. Fancy automated repricers — RepricerExpress, Aura, etc. Cost £30-£100/month. Don't install one in your first 30 days; you need to learn the market manually first. Even after, most UK arbitrage sellers do fine with manual repricing. "FBA accounting software" with monthly fees — if your turnover is under £30k, a Google Sheet beats this. Above £30k, a £40/month accountant is more valuable than software.

The minimum stack to start

Brand new and want to keep costs low? £35/month gets you: Keepa (£15) + SellerAmp (£20). Add Inner Circle Leads (£29.99) when you're ready to scale beyond what you can manually source. Total: £65/month. Most members find one good lead from us in their first week covers our membership cost; subsequent leads are pure margin.
