Client feedback
What our clients say
Furnace took over our Shopify trading, retention and Amazon, and moved us off our UK distributor without losing momentum. They even found us the right UK 3PL. It feels like having a senior e-commerce team in-house.
Furnace ran our UK launch from top to bottom, from finding the 3PL to running our website and Amazon. We now have a real foothold in the UK and a base to build our European business from.
Furnace runs our Amazon business globally. Sales are up 30% year on year, ROAS is at 3.4 and the channel is ten times more profitable than when they started.
Furnace launched our DTC site across the UK and Europe in local languages, moved our Amazon business from 1P to 3P, and took us live on Zalando, Otto, ASOS and John Lewis. One team, every channel, launched properly.

Questions
Who's actually working on my account?
A senior operator with hands-on experience running the channels you're hiring us for. Not an account manager, not a junior. Furnace is deliberately structured so the person you meet in the pitch is the person doing the work.
What does a typical engagement look like?
Most clients start on a monthly retainer covering one to three channels, with a three-month initial term and rolling monthly after that. Weekly trading reports, fortnightly review calls, and same-day responses on anything urgent during UK business hours. Most clients see material changes inside the first 30 days.
How big do we need to be to work with you?
Our best fit is brands doing £1–30m in annual revenue. Below that, a freelancer or fractional engagement is often the better shape. Above £30m, you may need a larger team — though we work with bigger brands on specific channels.
Are you exclusive to one client per category?
For most categories, no. We do offer category exclusivity where it's needed. We're currently locked out of eyelash and eyebrow growth/conditioning serums, and hair serums, foams and treatment products — and we're transparent about it upfront.
How fast can we start?
Discovery call this week, scope confirmed within 7 days, contracted and started within two weeks of scope sign-off. Most engagements kick off within three weeks of the first conversation.
Can we do project work or do we have to commit to a retainer?
Both. Retainer is best for ongoing channel ownership. Project work suits defined pieces — listing rebuilds, UK Amazon launches, retention programme setups, Shopify migrations. We'll be straight with you about which fits.
Do you actually do the work, or do you outsource it?
We do the work. No offshore listing teams, no white-labelled retention agencies behind us. Where we use specialist tooling or partners — DSP seat access, EU Responsible Person services, compliance vendors — we're transparent about it.
Which platforms and tools do you work with?
Amazon Seller Central and Vendor Central (UK, EU, US). Shopify and Shopify Plus. Klaviyo and Recharge. TikTok Shop and TikTok Ads. Zalando, Otto, About You, John Lewis and the other major European marketplaces. We are tool-agnostic — we will work with what you have if it is the right tool, and tell you when it is not.
Do you run paid social and Google Ads?
No, and deliberately. We run advertising on Amazon and TikTok, because those sit inside the channels we already own end to end. Meta and Google are better handled by a specialist, and we would rather tell you that than take the retainer.
Do you handle Amazon in the US or just the UK?
UK and EU as standard. We can extend to Amazon US, Canada and Australia for existing UK clients. We don't currently take US-only clients — there are better-fit agencies based in-market.
What do you need from us to start?
Access to your channels (Seller Central, Shopify admin, ESP, ad accounts, analytics), brand assets and guidelines, current product data and pricing, and a named point of contact who can give us decisions and feedback. We share a kick-off checklist after contracting.
How much of our team's time will this take?
Less than people expect, more than nothing. We need approvals and information at the start, then 30–45 minutes every fortnight on a review call plus async feedback. Most clients say the time investment drops materially after month one.
Who owns the work you create?
You do. All deliverables transfer to you on payment — listings, creatives, copy, dashboards, strategy documents. We retain rights to our internal tools and frameworks, as is standard for any agency.
What if it's not working?
30-day rolling notice after the first three months. We're built to earn the next month every month, not to lock you in. Most issues come down to scope misalignment that's fixable in a week of honest conversation.
Why are you better than the bigger agency we've shortlisted?
Probably not, for everything. They have more people and broader specialism. What we offer instead is senior operator time on your account, faster decisions, and less politics. If you want a 200-page strategy deck and a quarterly steering committee, we're the wrong call. If you want someone running your channels like an in-house Head of E-commerce, we're the right one.
Can you guarantee results?
No, and we'd be sceptical of anyone who does. We can guarantee how we work — weekly numbers, transparent reporting, senior operator on the account, fast execution. The results come from doing that consistently. Past client performance is the best signal you'll get, and we'll share it openly.
