Installing the Eofferix module for 1C-Bitrix

How to install the Eofferix module on a 1C-Bitrix site, remove the installer folder, check the connection, and continue setup.

Updated: Jul 18, 2026

The Eofferix module lets a 1C-Bitrix site receive the catalog prepared in Eofferix: sections, products, offers, images, files, and properties.

For the first setup, start with the full guide: exporting a catalog to 1C-Bitrix.

What You Need

  • A 1C-Bitrix user with administrator rights for installing solutions and managing site files.
  • Access to site files through the 1C-Bitrix file manager, hosting file manager, FTP/SFTP, or your site specialist.
  • The installer archive eofferix-bitrix-install.zip. For manual installation, use eofferix-bitrix-module.zip; the steps are below.

Install Through The 1C-Bitrix File Manager

  1. Sign in to the 1C-Bitrix admin panel with a user who has administrator rights.
  2. Open the site file manager. It is usually in Content → Files and folders.
  3. Open the main site folder. It should already contain bitrix and usually local.
  4. Upload eofferix-bitrix-install.zip to that main folder.
  5. Unpack the archive so that the eofferix-bitrix-install folder appears. The installer page should be /eofferix-bitrix-install/install.php.
  6. Open https://site.com/eofferix-bitrix-install/install.php.
  7. Wait for the success message.
  8. Delete the eofferix-bitrix-install folder and the ZIP archive from the site. The working module will remain installed.

Important: do not upload install.php and index.php from the archive directly into the site root. The site already has its own index.php, and it must not be replaced. The site should contain a separate eofferix-bitrix-install folder.

Install Through Hosting Or FTP

If you install the module outside the Bitrix admin panel, download eofferix-bitrix-install.zip, unpack it on your computer, and upload the whole eofferix-bitrix-install folder to the site. The folder must be next to bitrix. Then open https://site.com/eofferix-bitrix-install/install.php and delete the installer folder after success.

Manual Archive Without The Installer

eofferix-bitrix-module.zip is for manual installation when the normal installer is not suitable. It contains the ready module folder local/modules/eofferix.integration.

  1. Upload eofferix-bitrix-module.zip to the main site folder.
  2. Unpack it from the main site folder so that /local/modules/eofferix.integration/ appears.
  3. Open Marketplace → Installed solutions in the Bitrix admin panel, or open /bitrix/admin/partner_modules.php?lang=en.
  4. Find Eofferix Integration and install it. If the module was already installed, use this method together with a site specialist so they can check that the module service file was also updated.

Connect In Eofferix

Open the export profile, choose 1C-Bitrix, enter the site address and administrator login, then click Check connection. After a successful check, choose the Bitrix catalog.
