Amazon Netherlands & Germany
Freelance Amazon account manager for listings, advertising, Buy Box and stock
I'm Hans van Leeuwen, a freelance Amazon specialist based in Amersfoort, the Netherlands. I manage and grow Amazon.nl and Amazon.de accounts for brands that don't have a full-time specialist in-house. For Alpine Hearing Protection, Amazon NL was my daily work for four years: the earplug category there grew to a 70% market share (Nielsen, 2023), the Buy Box calmed down through price alignment with the B2B channels, and A/B tests on product images lifted conversion. At ABS All Brake Systems I currently run a catalogue of A.B.S. brake parts on Amazon DE alongside eBay DE and Bol.com.

Three situations I ran into on Amazon and wrote up:
As described in my article: for an outdoor brand on Amazon DE and Bol.com the problem wasn't the campaigns but the listing: no sizing in the gallery, generic A+ Content. After the rebuild conversion rose from 8.1% to 12.7% and returns dropped to 14%.
Read the case (Dutch)From my UX framework for LLMs: an AI tool wrote technically correct Amazon DE titles without the search terms that bring traffic. CTR fell 23% in six weeks before anyone checked manually. Since then every generated title carries a source and confidence label before it goes live.
Read the UX framework (Dutch)Amazon is investing €1.4 billion in Dutch logistics and, at the end of 2025, was searched for more often than Bol.com for the first time. My decision framework works on contribution margin per order, not commission percentage.
Read the comparison (Dutch)An engagement starts with a practical account baseline: catalogue health, listing quality, search-term coverage, campaign structure, pricing and Buy Box, stock risk, account warnings and reporting. The plan separates urgent revenue leaks from growth opportunities, with a measurable target and an owner for every action.
Execution connects content, advertising and operations. Search-term research feeds titles, bullets, backend keywords, A+ Content and the campaign structure, instead of treating each area as a separate project. A weekly trading review puts organic visibility, conversion, advertising efficiency, margin and availability side by side, so budget and catalogue decisions are made on commercial impact.
For ongoing management the cadence covers catalogue checks, campaign optimisation, price and Buy Box review, stock risk, competitor changes and a concise performance update. You keep access to every decision, dataset and working document: the goal is an Amazon operation your own team can understand and continue.
No agency margin, no six-month minimum, cancellable monthly. Three models, with indicative rates (excl. VAT):
After a 30-minute intro call you receive a written quote within one working day: scope, cadence and final rate. For context: a permanent e-commerce manager, including employer costs, quickly runs to €6,000 or more per month, without the option to stop monthly. An interim engagement of three days a week usually stays below that. All rates and what is included →
