ACHAT Z

E-commerce · Gennevilliers, France

E-commerce, powered by our own software.

ACHAT Z has been selling DIY and gardening products on Amazon since July 2025. To run this business, we are building our own management software, and we are exploring whether to offer it to other sellers one day.

01

Our business: selling online

Operating

We are an independent third-party seller on Amazon.fr, specialising in DIY and gardening.

Our model is online arbitrage: we find products at retailers whose price allows them to be resold on Amazon, buy them, inspect them on arrival, then list them for sale.

  • Product selection based on price and demand data
  • Every item tracked from purchase to sale
  • Returns, disputes and after-sales service handled with our suppliers
02

Our in-house management software

In daily use

Online arbitrage means many small operations running in parallel: purchases, orders, parcels, refunds, returns. Rather than stitching generic tools together, we built our own.

It covers the following areas:

  • Purchasing and orders
  • Inventory
  • Financial reconciliation
  • Returns and disputes
  • After-sales exchanges with suppliers

Our team uses it every day. Some modules are still being developed or migrated. For confidentiality reasons, we do not describe how it works.

Technical approach

The software was first built on Google Apps Script and Google Sheets. It is being migrated step by step to a PostgreSQL database hosted on Supabase, with automation, access control and regular backups.

For development, we use AI coding assistants, including Anthropic’s Claude.

03

An outlook: opening it to other sellers

Under study

Other online arbitrage sellers probably face the same difficulties we do. We are exploring whether to offer them our software.

Nothing is available today: there is no pricing and no launch date. If this interests you, write to us. Your feedback will help us decide.
