European Amazon Seller Tools

Amazon seller tools cover profit tracking, repricing, advertising, listing monitoring and product sourcing for marketplace sellers. Your sales, cost prices and supplier lists are commercially sensitive, and a tool run from an EU, UK, Swiss or Israeli entity keeps that data under European law and a European contract. The eleven tools below come from Germany, the UK, Ireland and France.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects whether a tool is listed. Editorial policy

Key takeaways

  • Sellerboard, run by nextechnology GmbH in Stuttgart, is the broadest single login on this page for profit, inventory and PPC reporting, and starts at $15 a month.
  • SellerLogic of Düsseldorf is the only repricer here with a free plan that has no end date, covering up to 20 optimised products a day.
  • Repricer.com is contracted with xSellco Limited in Dublin under Irish law, and its plans are sized by SKU count, from 3,000 to 250,000.
  • Adspert in Berlin charges a monthly fee of €99, €499 or €999 plus a commission on the ad sales it manages, so its total cost follows ad revenue.
  • Helium 10 is operated by Pixel Labs, LLC of Irvine, California, which is why this page splits its work across eleven tools from Germany, the UK, Ireland and France.

European Amazon seller tools are profit, repricing, advertising, listing-monitoring and sourcing software for marketplace sellers, operated by companies in Germany, the UK, Ireland and France, so cost prices, sales figures and supplier lists sit under a European contract instead of a US one.

Every European amazon seller tool reviewed

#1 Sellerboard

Stuttgart, Germany Founded 2017 Starting at $15 per month, 1 month free trial without credit card (homepage, 29 October 2026) Demo on request

Best for: Sellers who want true profit per product before anything else

  • Operating company. nextechnology GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Helium 10 (profit and operations tools)

Sellerboard turns Amazon fees, advertising, returns and your own purchase prices into a profit figure that can be followed down to a single order. A COGS module takes costs per product or batch, a trend view and a place for indirect expenses sit beside it, and data can be exported for an accountant. Around the dashboard are inventory planning, review requests, PPC and search term reports, a repricer and listing change alerts.

The operator is nextechnology GmbH, registered at the Amtsgericht Stuttgart under HRB 766168, which describes itself as a software business founded in 2017 with 20,000+ sellers. The vendor claims that user count. The homepage names $15 a month as the starting price and a free month without a credit card. Tier contents and the data location were not confirmed on the pages read.

What Sellerboard does well

  • Order-level profit view
  • Stuttgart GmbH with a register number
  • Stock, advertising and review tools under one login
  • Also available for Shopify, Walmart and eBay
  • One month free before payment

Where Sellerboard falls short

  • Plan contents hidden until sign-up
  • No product research database found
  • Dollar pricing
  • Hosting location not given

Standout feature. Sellerboard is the one tool on this page that starts from profit per order and builds inventory, PPC and a repricer around it.

#2 SellerLogic

Düsseldorf, Germany Free plan for up to 20 optimised products/day; paid Starter and Advanced tiers (amounts not published); 14-day free trial of full features Demo on request

Best for: Amazon sellers who want to test a repricer without paying first

  • Operating company. SellerLogic GmbH
  • Jurisdiction. EU (Germany)
  • Source code. Closed source
  • Replaces. BQool, Informed.co, RepricerExpress

SellerLogic is a repricer built for Amazon, and its distinguishing offer is a free plan with no expiry that optimises up to 20 products a day, synchronising every four hours. A seller can see whether dynamic pricing helps before spending anything, which differs from a trial that ends and leaves nothing behind.

SellerLogic GmbH is entered at Düsseldorf under HRB 79970. Paid tiers speed up synchronisation, down to hourly on the Advanced plan, and add margin tracking across several Amazon marketplaces for wholesale and private-label sellers. The amounts for the paid tiers are not published, and the tool covers Amazon only, with no webshop repricing.

What SellerLogic does well

  • Permanent free plan, rare in this category
  • 14 days of every paid feature on trial
  • Düsseldorf company under EU law
  • Margins tracked across marketplaces for wholesale and private-label sellers

Where SellerLogic falls short

  • Amazon only, with no webshop or multichannel repricing
  • Paid tier amounts unpublished
  • Smaller scope than a pricing-management platform

Standout feature. SellerLogic lets a small seller run a repricer indefinitely at no cost, which no other tool on this page offers.

Best for: Brands and agencies with big catalogues where listings change without warning

  • Operating company. AMALYTIX GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Not stated; AI agent uses models in Amazon Bedrock
  • Source code. Closed source
  • Replaces. Helium 10 (listing alerts and monitoring)

AMALYTIX is built around Amazon overwriting your product pages. Each product is compared with a saved snapshot every day, and an alert goes to e-mail or Slack when a title, bullet point, Buy Box owner, stock level or search position differs. Watchlists, account health and seller feedback views sit next to the alerts.

The imprint names AMALYTIX GmbH of Cologne, Amtsgericht Köln HRB 100547. According to the site, workflows on the Scale plan can push saved content back to Amazon by rule and, for vendor products, prepare a support case. Seller Central and Vendor Central are both supported, with a 14-day trial and no published prices. The AI agent runs on models in Amazon Bedrock.

What AMALYTIX does well

  • Each listing checked against a daily snapshot
  • Works with Seller and Vendor Central
  • Rules can put changed content back
  • Permissions and dashboards for agencies
  • Cologne GmbH with a register entry

Where AMALYTIX falls short

  • Prices not shown
  • Workflows need a higher plan

Best for: Sellers who want software to run advertising against an ACoS or ROAS target

  • Operating company. Adspert GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Helium 10 (Ads)

Adspert sets bids and keywords toward a goal such as an ACoS or ROAS level, and a simulation shows the effect on KPIs before a change goes live. The Essential plan lists AI-driven automated bidding, goal setup assistance and budget suggestions. Amazon Ads, eBay Advertising and Walmart Connect are supported, with Google and Microsoft Ads on the Scale plan.

The imprint lists Adspert GmbH at Borsigstr. 8 in Berlin, registered at the Amtsgericht Berlin-Charlottenburg under HRB 133120 B. Plans cost €99, €499 and €999 a month, each plus a commission that applies only to sales attributed to Adspert on Amazon Ads and eBay Advertising. Organic sales are excluded, and Essential includes 30 free days without a card.

What Adspert does well

  • Monthly fees spelled out per plan
  • Five ad networks managed together
  • Trial without a credit card
  • Simulates a goal before applying it
  • Berlin GmbH with HRB entry

Where Adspert falls short

  • Advertising is the only function
  • Fee plus commission
  • Google Ads and success manager on higher plans
  • Bill varies with ad sales

Standout feature. Adspert combines a published euro fee with a commission on the ad sales it manages, so its price follows results.

Best for: Sellers who compete on price for the Buy Box on several marketplaces

Best for: Agencies and brands who read sales, ads and organic data together

  • Operating company. Worldeye Technologies Europe (SAS)
  • Jurisdiction. EU (France)

Agency pages describe a multi-account dashboard, white-label reports, AI alerts and role-based access, with BI connections on the enterprise side.

The terms name Worldeye Technologies Europe, a French simplified joint-stock company registered in Paris under number 942 570 011. The Sherlock AI agent, which explains a performance change and suggests a fix, was a waitlisted beta when checked, and an MCP integration links assistants to the same data.

#8 ProfitPath

Leverkusen, Germany Four plans (Manual, Wholesale, Automated, All Inclusive); amounts not visible; 14-day free trial Demo on request

Best for: Online arbitrage and wholesale buyers sourcing in Europe and the UK

  • Operating company. FourByte GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Helium 10 (sourcing and product tools)

A2A Search compares Amazon marketplaces in the EU and UK for price gaps.

The imprint names FourByte GmbH of Leverkusen, registered in Cologne under HRB 129836.

  • Analyses wholesale lists
  • Notifies you when profit goals are reached
  • Leverkusen GmbH with commercial register entry

Where ProfitPath falls short

  • Amounts hidden
  • No ads, listing or profit modules
  • Suppliers limited to Europe and the UK
  • Depth differs between plans

Standout feature. ProfitPath begins with supplier shop prices and works toward the Amazon listing, the reverse of a research database.

#9 Billbee

Twistetal, Germany Usage-based on order volume with a minimum fee of EUR 9 per month net of VAT; up to 200 orders a month is the Starter plan, above that the Growth plan, both with all features, all integrations and unlimited users; no minimum contract term Demo on request

Best for: Small and mid-sized sellers who run orders from several shops and marketplaces

  • Operating company. Billbee GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Germany: Billbee states its servers are in the Hetzner data center park in Nuremberg
  • Source code. Closed source
  • Replaces. Cin7, Sortly, Linnworks

The vendor counts more than 150 connections, naming Shopify, WooCommerce, Amazon, eBay, Etsy, Shopware, DHL, DATEV and others, and states over 20,000 online sellers.

Billbee GmbH is registered at the Korbach court under HRB 2482, in Twistetal, and says it belongs to comrce, whose owner neither site names. The servers are in the Hetzner park in Nuremberg.

Munich, Germany Founded 2012 Not published on the pages checked Demo on request

Best for: Brands that want specialists and software to run Amazon Ads together

  • Operating company. Averest Consulting GmbH (formerly metoda GmbH)
  • Jurisdiction. EU (Germany)
  • Where the data sits. Website analytics hosted in Ireland
  • Source code. Closed source
  • Replaces. Helium 10 (Ads)

metoda combines an Ad Optimizer for Sponsored Products, Brands and Display with an agency service covering Amazon DSP and Amazon Marketing Cloud. Reporting dashboards come with it, and so do consulting and a Price API that crawls e-commerce data for competitor price monitoring, the line the company started with.

The company began in 2012 as PreisAnalytics and states a team above 40. A news item on its site says metoda GmbH was renamed Averest Consulting GmbH, which the privacy page names as the responsible party at Bayerstraße 69 in Munich. Website analytics run on Matomo hosted in Ireland. Pricing is not published and the offer is led by the agency, not self-serve.

What metoda does well

  • Software plus people on one contract
  • Reaches DSP and Amazon Marketing Cloud
  • Competitor price data via an API
  • Munich company founded in 2012
  • Site available in several languages

Ansbach, Germany Success-based model, no list prices (see website) Demo on request

Best for: Fashion and lifestyle brands selling on Zalando, ABOUT YOU and similar marketplaces

  • Operating company. Tradebyte Software GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Not stated on the pages reviewed
  • Source code. Closed source
  • Replaces. Feedonomics (for marketplace listings)

Tradebyte positions itself as Europe's integrator for fashion and lifestyle. A catalogue is uploaded once and adapted to the sizes, categories and compliance rules of 90+ marketplaces, including Zalando and ABOUT YOU, with Smart Attribute Mapping and error tracking that shows each article's publication status. The vendor says its AI classification is trained on fashion taxonomy.

The imprint names Tradebyte Software GmbH in Ansbach, registered at the district court under HRB 4609. A dashboard shows GMV, return rate and item performance by marketplace, country and category, with anomaly alerts, and every customer gets a named success manager. The model is described as success-based, no prices are shown, and the hosting location is not stated.

What Tradebyte does well

  • Catalogue adapted to each marketplace's specifications
  • Zalando and ABOUT YOU among 90+ channels
  • Analytics across channels with anomaly alerts
  • Named success manager
  • GmbH with a register number

Where Tradebyte falls short

  • Built for fashion and lifestyle
  • Not for Google Shopping feed edits
  • No list prices
  • Hosting location missing

Standout feature. Tradebyte adapts one fashion catalogue to the rules of each of 90+ marketplaces.

Which job should I move to a European tool first?

Start with the job where you feel the most pain and where the data is most sensitive. For many sellers that is profit, because it needs cost prices per product. Sellerboard handles that with a COGS module and a dashboard that goes down to a single order, and SellerLogic offers margin tracking across Amazon marketplaces.

If advertising is your largest expense, Adspert or metoda is the first move instead. If you worry more about Amazon changing your pages, AMALYTIX compares each listing against a daily snapshot. None of these needs the others, so a staged move is realistic.

How do the pricing models of these tools differ?

Three patterns appear. Flat monthly plans: Sellerboard from $15, SellerAmp at $19.95, $29.95 or $49.95, and Repricer.com at $99, $299 or $499 depending on SKU count. Fee plus commission: Adspert at €99, €499 or €999 plus a share of attributed ad sales. Order-based: Billbee at a €9 minimum net of VAT.

A fourth group publishes no amounts on the pages checked: AMALYTIX, DataHawk, ProfitPath, metoda and Tradebyte, whose model is described as success-based. SellerLogic publishes its free plan but not its paid tiers. Ask for quotes before comparing totals.

Where does my seller data end up with a European tool?

The contracting entity is easy to read from the imprint or terms: nextechnology GmbH in Stuttgart, AMALYTIX GmbH in Cologne, FourByte GmbH in Leverkusen, xSellco Limited in Dublin, Worldeye Technologies Europe in Paris. SellerAmp Limited is a British company, so it falls under UK law and an adequacy decision rather than EU membership.

Hosting is a separate question. Only Billbee names a data centre, the Hetzner park in Nuremberg, and metoda states that its website analytics run in Ireland. For the rest the pages checked do not say where data sits, and AMALYTIX adds that its AI agent uses models in Amazon Bedrock. Ask each vendor in writing.

What changes when I leave Helium 10?

Helium 10 is operated by Pixel Labs, LLC in Irvine, California, and its privacy policy says information can be processed on US servers. Leaving means replacing one login with several, each connected to Seller Central separately. Sellerboard comes closest as a single replacement, but its public pages show no product research database.

Keep what you still use. Many sellers hold a smaller Helium 10 plan for research for a few months while profit, ads and monitoring run on European tools, then decide. Export cost prices and history before cancelling.

When should I not switch?

Do not switch if keyword and product research is what you pay for and your volume does not justify a second tool. Do not switch mid-season with a large ad budget running, since moving bidding to Adspert or metoda needs a learning period. Do not switch only for jurisdiction if your own data protection review has already accepted the current setup.

A European contract changes who you sign with and which law applies. It does not by itself make the tool better at the job, so judge each one on the trial, using your own catalogue.

How do these tools fit with a webshop and other marketplaces?

Repricer.com and Adspert reach eBay and Walmart, DataHawk covers Amazon and Walmart, and Sellerboard has Shopify, Walmart and eBay versions. Billbee brings orders, invoices, stock and shipping from more than 150 connections into one account, and Tradebyte adapts a fashion catalogue to over 90 marketplaces.

A seller with only Amazon needs few of these. A seller with a webshop and two marketplaces should check the marketplace list of each tool on its own pricing page before paying.

How we selected and ranked these 11 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

  1. Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
  2. Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
  3. Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
  4. Editorial review. Every page is researched and drafted with AI assistance, and the compliance and pricing claims are checked against the vendor's documentation before it is published under the founder's editorial responsibility. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

Sellerboard ranks first on this page for profit tracking with inventory and PPC reports, SellerLogic and Repricer.com are the repricers, Adspert and metoda handle advertising, AMALYTIX handles listing monitoring, and SellerAmp and ProfitPath cover sourcing. No single tool matches a full US suite.

DataHawk lists multi-account dashboards, white-label reports and role-based access, AMALYTIX lists agency permissions and dashboards, and Adspert lists agency settings on its Scale plan. metoda runs Amazon Ads as an agency service next to its software.

Adspert quotes €99, €499 and €999 per month plus commission, and Billbee quotes a €9 monthly minimum net of VAT. Sellerboard, SellerAmp and Repricer.com quote in US dollars, and several others publish no amounts.

ProfitPath scans more than 1,000 European online shops daily, and SellerAmp checks fees, ROI and eligibility for a candidate product. Neither is a keyword database for private-label research.

Most are: Germany, France and Ireland are EU members. SellerAmp Limited is in Halifax in the United Kingdom, which is outside the EEA but covered by an adequacy decision.
