PROFESSIONAL EXPERIENCE
Marketplace / E-commerce Account Manager
Private E-commerce Company (name withheld under NDA) | October 2021 – September 2026
• Led end-to-end launch and management of seller accounts across Amazon EU, Allegro, eMAG, Kaufland.de and Worten — registration, bank/card verification, and go-to-market setup.
• Owned EU VAT and packaging-compliance (EPR/LUCID-type) processes for multiple entities across several EU countries: managed registrations, deadlines and reporting calendars, coordinated tax/EPR providers (e.g. Taxually), controlled primary bookkeeping, and configured Amazon so VAT/FBA and invoicing worked correctly (invoices, credit notes to customers). Owned the process end-to-end rather than performing the tax calculations personally.
• Managed logistics end-to-end: Amazon FBA and Allegro One Fulfillment shipments (account setup, inbound shipping, labeling requirements), own-warehouse fulfillment (FBM), stock replenishment, returns, and removal/liquidation/disposal orders; liaised with Amazon's logistics team as the point of contact for fulfillment centers in Italy, Spain, Portugal, Romania and Poland, and negotiated pricing directly with Allegro warehouse partners.
• Built and optimized product listings and brand pages (titles, bullet points, keywords, images, variation families, A+ Content and Brand Store) based on competitor research and design briefs to designers.
• Managed full-lifecycle catalog operations via Amazon Seller Central using flat files: new listing creation, parent/child variation setup, and bulk removals; prepared MSDS/SDS documentation for battery-powered products, Hazmat Exemption Sheets, and routed Hazmat-classified inventory to dedicated FBA warehouses.
• Built and managed Sponsored Products PPC campaigns from scratch; made budget and bid decisions per product based on profitability/ROI data rather than following a fixed playbook.
• Calculated and maintained unit economics and P&L by product/SKU (COGS, logistics, Amazon/marketplace fees, ad spend) to guide pricing, budget and go/no-go decisions.
• Enrolled branded products in Amazon Vine to generate early reviews, and ran Coupons/deals to support launches and promotions.
• Owned account health and compliance across managed accounts: resolved compliance notices (Responsible Person, manufacturer information, pre-market/product safety notices), fixed or appealed listing removals within deadline (coordinating required documentation with legal team), and resolved account reactivations — including director/company representative identity, address, utility bill, bank account and credit card verifications, work after transitions to Deemed Supplier/Seller status where EU establishment could not be evidenced. On Allegro, monitored and corrected account metrics to receie and maintain Super Seller status.
• Registered 3 trademarks via Amazon Brand Registry / IP Accelerator (including resolving a naming conflict with legal counsel), and added/transferred another 4 trademarks between seller accounts and marketplaces.
• Protected brand IP against counterfeits and unauthorized sellers: identified counterfeit listings and unauthorized sales under the brand's identity, and filed infringement complaints (backed by trademark/logo ownership documentation) to get infringing listings removed or blocked on Amazon.
• Worked regularly with Amazon Business Reports, Transactions Reports, FBA Stock Reports and the VAT Transactions Report; owned monthly sales and net-profit reporting across all marketplaces, factoring in full operating costs.
• Ran up to 3 legal entities in parallel, reaching combined monthly turnover of up to €50–80K; onboarded and listed up to 50 SKUs per account, primarily via FBA to protect account health.
• Maintained an average seller rating of 4.5+ across all managed accounts over 5 years (Italy account: ~4.9 rating, 100+ reviews).
• Managed a small team: hired and directed an assistant, set and tracked tasks, coordinated with logistics and marketing departments; briefed and supervised designers and copywriters.
• Worked closely with the company's legal team — coordinating preparation of required documents (or sourcing existing ones) for trademark protection, account reactivations, and listing disputes. Partnered with the accounting and financial-analytics team: briefed them on marketplace-specific report types, seller/buyer invoices and credit notes, helped set up buyer invoicing on Allegro and other marketplaces, and jointly prepared documentation for account unblocking or new account setup.
Amazon Account Manager — Private Label
Freelance / Private Projects | 2017 – 2021
• Ran private-label projects on Amazon US in partnership with a business partner: sourced factories remotely on Alibaba for target volumes, negotiated samples, product customization, pricing, lead times and delivery terms, plus brand story creation and stock planning.
• Completed multiple freelance e-commerce projects: product research, competitor analysis, and full seller-account setup for Amazon, Etsy and eBay clients.
