Proof

What our clients say, and where they said it.

Reviews are grouped by the platform they were left on, each one dated and linked back to its source so you can read it somewhere we cannot edit it. Where a client wrote to us directly rather than posting publicly, the card says so instead of dressing it up as a third-party review.

Video testimonials

Recorded by clients in their own words. The pull quote under each clip is transcribed from it, so the words are in the page for anyone reading rather than watching.

Credentials

Who you would actually be handing the keys to.

6+ years

Running e-commerce supply chain operations

Operating since 2020 under Ecom Store LLC, a registered Wyoming limited liability company.

One

Named operator who owns each account

Every engagement has a single operator accountable for it, with named cover on the shifts either side. Each operator holds their own credentials and is granted access only to the accounts they run.

7

Sales channels operated

Amazon, Shopify, Walmart Marketplace, TikTok Shop, Wayfair, Faire, and eBay, planned from one inventory position.

24/7

Coverage across three shifts

Asia, Europe and Americas shifts, so supplier hours and seller hours are both covered. Shift windows are published on the About page.

Training and standards we hold ourselves to

  • Operators complete Amazon Seller University coursework on FBA inventory management, inbound shipment creation, and account health during onboarding.
  • We operate under Amazon's Data Protection Policy for all Selling Partner data we are given access to.
  • FBA policy changes are tracked in internal documentation that is reviewed and reissued to the operations team.
  • Access to any client account is granted per operator, per account, and revoked on offboarding.

We do not hold a SOC 2 Type II report or an ISO 27001 certificate, and we do not claim either. The controls we do operate are written out in full on our security page, and we will walk any of them through with you before you grant access.

Where we operate

  • Amazon North America (US, Canada, Mexico)
  • Amazon Europe (UK, Germany, France, Italy, Spain)
  • Walmart Marketplace and WFS (US)
  • Shopify (worldwide)
  • TikTok Shop (US, UK)
  • eBay, Wayfair and Faire (US)
Success stories

Engagements where the numbers are ours to share.

Each of these is a real engagement written up with the working shown: what the problem was, what we did, and what it was worth. Client names are used only where we have written permission.
