About
Freelance E-commerce Manager & Marketplace Specialist (Amazon & Bol.com)
Hans van Leeuwen · Amersfoort, NL
E-commerce Manager with 10+ years of experience accelerating digital commerce performance across marketplaces and D2C channels. Specializing in Amazon, Bol.com, AI-assisted e-commerce automation, and scalable revenue growth strategies.
I combine a strong background in UX design with hands-on commercial expertise to create data-driven strategies that deliver measurable results. From achieving 70% market share on Amazon NL to cutting out-of-stock rates below 2%, I turn complexity into growth.
How I work
Every engagement runs through four phases. Compact and measurable, no abstract framework — just what happens each week and which KPIs move.
Discovery
Audit current marketplace presence, identify quick wins and structural growth levers.
Strategy
Action plan with KPIs, timelines and clear ownership per lever.
Execution
Hands-on: listings, A+ content, Amazon Ads and Bol Ads, with weekly check-ins.
Scale
Iterate based on data, expand to new channels (DE, FR) and compound results.
Frequently Asked Questions
What does a freelance e-commerce manager do?
I temporarily lead the e-commerce operation: marketplace strategy, listings, advertising, pricing, forecasting and reporting. Hands-on inside your existing team and tool stack.
How much does marketplace management cost?
Retainer for ongoing Amazon/Bol management, project pricing for a defined audit or launch, day rate for interim. Actual number depends on scope; a 30-min intake produces a written quote within one working day.
Bol.com — vendor or seller?
Seller keeps margin and control but requires active account work. Vendor saves operations but concedes margin and pricing control. I model both routes on EBITDA, not just revenue.
How do you reduce out-of-stock rates?
A demand-forecasting model built on recent sell-through, seasonality and promo lift, tied to supplier lead-times. Documented cases run under 2% OOS.
Do you manage Amazon Ads and Bol Ads?
Yes. Sponsored Products, Sponsored Brands, Display and Bol Ads with weekly bid steering and negative harvesting; ACOS/TACOS as primary KPIs.
