QUICK ANSWER
Replenishment-only UK FBA stack at ~£75-95/month: Keepa Premium (~£16), SellerAmp SAS (~£15), SellerBoard (~£15-20), Wise Business (free), GETIDA (free until recovery), Source2Store (~£40-65). That's it. Skip Helium 10, Jungle Scout, BuyBotPro, Tactical Arbitrage, Inventory Lab, and any AI-content-anything. Replenishment doesn't need new product research, listing optimisation, or PPC — it needs sourcing efficiency and profit visibility, both of which this stack covers.
What replenishment-only means
Replenishment is restocking existing ASINs you've already validated as profitable. No new product launches, no listing optimisation, no PPC. The job is: find replens, validate the deal, buy, ship to FBA, watch the P&L, recover reimbursements. That's it.
Most £10-50K/month UK FBA operators are 70-90% replenishment by revenue. The tool stack reflects that.

Per-deal validator. ROI, eligibility, hazmat, IP-claim flags. SellerAmp.
3. SellerBoard — ~£15-20/mo
Daily P&L truth source. Catches when a stable replen quietly turns unprofitable from a fee change or return-rate spike. SellerBoard.

What you don't need
- Helium 10 / Jungle Scout. Private-label tools. Not for replens.
- BuyBotPro. Past 90 days, SAS does the same job for half the cost.
- Tactical Arbitrage. Bulk supplier scanning. Replens already have known suppliers.
- Inventory Lab. Listing creation tool. Replens use existing listings.
- An AI repricer below 50 SKUs. Manual pricing covers it.
- Any course or community above £100/month. The lean stack outputs tell you everything you need to make daily decisions. Save the course budget for inventory.
The verdict
For UK FBA replenishment-only operators under 100 SKUs: ~£46/month base stack, ~£86-111/month with paid lead service. That's it.
The trap most operators fall into is layering tools as a comfort blanket. Each tool you add is another login, another dashboard, another £15-75 monthly. Cheaper, and more disciplined, to run a focused stack and put the saved capital into inventory.
FAQ
What's the minimum tool stack for UK FBA replenishment?
Keepa Premium (~£16/mo) + SellerAmp SAS (~£15/mo) + SellerBoard (~£15/mo) = ~£46/month. Add free Wise Business and GETIDA (commission only). That's the base — add Source2Store at ~£40-65/mo if you need more lead flow.
Do I need Helium 10 for UK FBA replenishment?
No. H10 is built for private-label launches and listing optimisation. Replenishment uses existing listings — none of H10's tools apply. Save the ~£75/month.
Is Source2Store essential for UK replenishment sellers?
Not essential. If your existing replen list is stable and growing slowly, free UK OA Discord channels + Keepa Product Finder cover sourcing. Add S2S when you're actively expanding the SKU list.
What about Tactical Arbitrage for replenishment?
Skip until you're £30K+/month with VA capacity. Even then, only run it monthly to audit existing replens against alternative suppliers — not as an ongoing subscription.
Do I need an Amazon repricer for under 100 SKUs?
Under 50 SKUs, no — manual pricing every 2-3 days is faster. 50-100 SKUs, consider Ascent for the AI margin retention. Read our repricer-under-50-SKUs guide for the breakeven math.
What's the realistic monthly cost of running UK FBA?
Tools at ~£46-111/month, FBA fees + advertising at 25-35% of revenue, COGS at 30-50%, accountant at £50-150/month, plus inventory financing. For a £20K/month seller, total operating expenses (excl. inventory) are typically £1,500-£2,500/month.
