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

Inner Circle FBA membership (£29.99/month Leads tier, £69.99 Tools Suite, £119 Mentoring Pro) — the Leads tier already includes the Companion Chrome extension: a live profit/margin/ROI verdict and a Keepa-style price/BSR chart injected onto every Amazon page, plus a restriction/eligibility check with one-click Auto-Ungate. On top of that: 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. Keepa (~£15-£40/month depending on tier) — still worth it specifically for multi-year, multi-region price/rank history or raw API access. The Companion's own chart covers the last year, UK only, so keep Keepa for anything deeper than that. SellerAmp SAS (~£20/month) — still the best mobile in-store scanner in the space (fastest for standing in a shop aisle with your phone). For desktop/online scanning the Companion covers the same ground already included in Leads. Alternative: BuyBotPro (similar concept, slightly different UX).

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? Inner Circle Leads (£29.99/month) alone already covers the on-page profit verdict and price/BSR chart most beginners reach for Keepa and SellerAmp for, plus daily leads to learn from. Add a standalone Keepa (£15/month) only if you specifically need multi-year history, or SellerAmp (£20/month) only if you're doing serious mobile in-store scanning. Most members find one good lead from us in their first week covers our membership cost; subsequent leads are pure margin.
