Who we are

A full-cycle operator for serious e-commerce capital.

STOCKLINE is an operations company, not a course. Investors and entrepreneurs hand us a budget and a goal — we deliver a working, profitable storefront on Amazon and eBay with all the unglamorous work done: legal entity routing, supplier vetting, listings, prep, shipping, customer support, reconciliation.

  • Single point of contact. One team owns the outcome.
  • Own prep centers. No third-party guesswork.
  • Honest reporting. P&L the way you'd read it.

Every step between capital and cashflow.

Pick a single service or hand us the whole operation. Most clients start with the full A-to-Z package.

Prep centers

Our own prep centers — not a partner network.

Inventory passes through facilities we operate. That means predictable lead times, photographic check-in, and no finger-pointing when something goes wrong.

How it works

From first call to first profitable month.

A predictable five-step path. You always know what's next and who is responsible.

  1. 01

    Discover

    Goals, budget, regions, risk profile. We confirm what's realistic before anything is signed.

  2. 02

    Setup

    Entity routing, seller accounts, supplier shortlist, prep center allocation.

  3. 03

    Launch

    First SKUs go live. Listings, ads, fulfillment and support all running under one roof.

  4. 04

    Scale

    Winners get more inventory and budget. Losers get cut. Catalog rotates on data, not feelings.

  5. 05

    Report

    Monthly P&L, cash position, next-month plan. Same format every time.

Clients

What operators say after a year with us.

M
Marek KowalInvestor, Warsaw
"I wired the budget and went on with my life. Eleven months in, the store covers my office costs and then some. The reports are boring — that's the compliment."
A
Anna LindqvistBrand owner, Stockholm
"We migrated three EU storefronts and the US listing in one quarter. Prep center photos saved us during an Amazon dispute — case closed in two days."
D
David O'ConnorFounder, Dublin
"Honest about what wouldn't work. They killed two SKUs I was emotional about and replaced them with winners. Margin doubled."
J
Julia ReiterOperator, Berlin
"Their automation stack replaced two full-time hires. PPC and repricing finally have an adult in the room."
P
Piotr NowakWholesaler, Kraków
"We send pallets, they handle everything from FNSKU to FBA inbound. Our error rate dropped from 3% to under 0.4%."
S
Sara BeltránBrand, Madrid
"They recovered a suspended account in eleven days. I'd given up. Now it's our second-best storefront."
T
Thomas WeberInvestor, Zürich
"What I value most: nobody promised me 10x. They promised a process. The process worked."

EU marketplaces (DE, FR, IT, ES, PL, NL, SE) and US. UK on request.
What does reporting look like?
A live dashboard plus a fixed-format monthly P&L: revenue, COGS, marketplace fees, ads, prep, logistics, net margin, cash position, next-month plan.
