You connect Syntess in 2026 with eConnect via the ClientConnector, eConnect's CLI tool for Windows. The tool exchanges invoices via a local folder structure on your PC. This is ideal for on-premise software that does not support a direct API connection. The ClientConnector runs on Windows and synchronizes files between Syntess and eConnect.

Before you start
  • An active eConnect account with at least a Professional subscription
  • A subscription key (via sales, with Professional)
  • The ClientConnector tool for Windows
  • Syntess Professional subscription
Setting up the integration
Step 1: Request a subscription key

Contact the eConnect sales team to request a subscription key for the ClientConnector.

Step 2: Install the ClientConnector
  1. Download the ClientConnector tool (available upon request via eConnect support).
  2. Install the tool on the same machine where Syntess runs, or on a shared drive accessible by Syntess.
  3. Configure the local folders: one folder for outgoing invoices (from Syntess to eConnect) and one for incoming invoices (from eConnect to Syntess).
Step 3: Set up connection keys and folders
  1. Enter your connection keys and subscription key in the ClientConnector.
  2. Configure the export/import folders in Syntess to match the ClientConnector folders.
  3. Start the ClientConnector; it monitors the folders and processes files automatically.
Step 4: Test

Place a test invoice in the outgoing folder and verify that it appears in your eConnect Outbox. Received invoices appear in the incoming folder.
