The PrestaShop moduleyour shop is missing.

Kosmonaft designs and builds custom PrestaShop modules: marketplace and carrier integrations, connectors to your ERP or warehouse, back-office tools, checkout features. If your shop needs it, I can build it.

Custom modules, built around how your shop works

A marketplace, a carrier, an internal tool or a feature nobody sells yet: you describe the need, I build the module. PrestaShop today, Shopify apps in development.

  • Integrations with any API

    Marketplaces, carriers, payment providers, logistics platforms or SaaS tools, whether a module already exists or not.

    For example: order import, stock sync, label printing, tracking updates.

  • Connectors to your own systems

    Keep products, prices, stock and orders in step between PrestaShop and the software you already run.

    For example: ERP, PIM, WMS, accounting exports.

  • Features for your business rules

    Pricing rules, checkout steps, product options, back-office screens and automations that PrestaShop doesn't do out of the box.

    For example: B2B pricing, custom exports, order workflows.

  • Upgrades and fixes

    Bring an existing module to PrestaShop 8 or 9 and PHP 8, or repair one that broke after an update.

    For example: version migration, hooks, performance on large catalogues.

How a project runs

  1. 1

    Email

    You describe your shop, the tools involved and your deadline.

  2. 2

    Written quote

    Scope, price and delivery date, in writing before any work starts.

  3. 3

    Build on staging

    You test on a copy of your shop before anything touches production.

  4. 4

    Release

    Installation on your live shop, documentation, and follow-up if something comes up.

Modules already in production

Built and maintained by me. Use one as it is, or as the starting point for your own version. Relay Max is sold on PrestaShop Addons; the others are available directly, on request.
