# /case-studies/thone โ€” Thone ยท Hearing protection # https://o1.eu/case-studies/thone # Operator One โ€” Merchant of Record for European marketplaces. ## Summary A Dutch hearing-protection brand went from one home market to four countries on Amazon, with compliance, VAT, listings and advertising carried by one operation. ## Result 4 countries โ€” Germany, the UK, France and the Netherlands, all on Amazon ## At a glance - 4 countries: Germany, the United Kingdom, France and the Netherlands - 1 marketplace: Amazon, four European storefronts, four languages - About 2.2x: Peak trading measured against the opening months - Full control: Official listings, buy box and pricing to the brand's rules ## Markets live Netherlands, Germany, France, United Kingdom ## Marketplaces live on Amazon ## Challenge Thone makes filtered earplugs people actually wear: roughly 20 to 26 dB off the volume, music still intelligible, click-on skins so protection reads as an accessory. Demand was never the problem. Reach was. One home market was open and the three biggest ones next door were not. Opening them meant PPE conformity per jurisdiction, VAT registrations and a full listing build in three more languages: months of administration for a small team whose real edge is acoustics and design. ## What changed under Operator One - Market access went from one country to four, the Netherlands, Germany, France and the United Kingdom, opened as four storefronts in four languages without the brand setting up anything new abroad. - Registrations, VAT positions and fiscal representation were carried per market, including the separate United Kingdom position. - Conformity documentation and producer registrations were kept current per country, so no compliance gap could take a market offline. - Around 20 products were built once and localised into four languages, with official listings using the brand's own imagery and copy. - Advertising ran per storefront, the buy box was held, and the brand kept its inventory and its own pricing strategy. - At its peak the operation was running about 2.2 times its opening months. ## Outcome Four countries trading from one operation, all on Amazon: Germany, the United Kingdom, France and the Netherlands. Listings are official, the buy box is held, and pricing follows the brand's own strategy. At its peak the operation was running about 2.2 times its opening months, and it is still running. ## Who this applies to Any brand with a certified product and one open market has this gap: the product is ready, the market access is not. Conformity files, VAT positions and producer registrations are per country, and they cost the same whether you sell a little or a lot there. Carry them once and the map opens. ## Story Certified for Europe, selling in one country Thone makes reusable filtered earplugs for people who want to hear the music and keep their hearing. A membrane filter takes roughly 20 to 26 dB off the volume without turning the sound to mud, and the designer line uses click-on skins so the protection is worn on show rather than hidden. It is hearing protection built as an accessory, with a small range of earbuds alongside. The product was ready. The market was not. A Dutch company can sell in the Netherlands tomorrow; selling certified protective equipment in Germany, France and the United Kingdom is a different job. Each one wants its own VAT position, its own producer registrations and a conformity file its own regulator will accept. That is not one operation. It is four. What the operation carried O1 took the selling side so the brand could stay on product. Entities, VAT registrations and fiscal representation per market, including the separate United Kingdom position. Product compliance: conformity documentation and producer registrations kept current in every country, so a compliance gap could never take a whole market offline. Catalogue build: around 20 products listed once and localised into Dutch, German, French and English, using the brand's own imagery and copy rather than somebody's approximation. Advertising per storefront, buy-box and pricing control, and customer service and returns answered in the local language. Reach Four countries: the Netherlands, Germany, France and the United Kingdom. One marketplace, Amazon, across four European storefronts in four languages. Three markets that had been shut, opened without the brand setting up anything new abroad. Control Listings are official. Product pages carry the brand's photography, its language and its claims about filtering and fit. The brand keeps its inventory and sets its own pricing strategy. Nothing about the shelf is left to whoever got there first. Growth At its peak the operation was running about 2.2 times its opening months, and it is still trading. That came from the same catalogue: no new products were needed, only markets that could finally buy them. Why it transfers Any brand with a certified product and one open market has this gap. Certification work, VAT positions and producer registrations are per country, and they cost the same whether you sell a little or a lot in that country. Carry them once and the map opens.
