In 2026, you connect Syntess 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 begin
  • An active eConnect account with at least a Professional subscription
  • A subscription key (via sales, included with Professional)
  • The ClientConnector tool for Windows
  • Syntess Professional subscription
Setting up the connection
Step 1: Request a subscription key

Contact eConnect's sales department to request a subscription key for the ClientConnector.

Step 2: Install the ClientConnector
  1. Download the ClientConnector tool (available on request from eConnect support).
  2. Install the tool on the same machine where Syntess runs, or on a shared drive that Syntess can reach.
  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. Set 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 check that it appears in your eConnect Outbox. Received invoices appear in the incoming folder.

Frequently asked questions
What is the ClientConnector and how does it work?

The ClientConnector is eConnect's CLI tool for Windows that exchanges invoices via a local folder structure. The tool monitors folders on your PC: files in the outgoing folder are sent to eConnect, and received invoices are placed in the incoming folder.

Do I need a subscription key for the ClientConnector?

Yes, you need a subscription key that you request from eConnect's sales department. You also need at least a Professional subscription. You enter the subscription key together with your connection keys in the ClientConnector.

Can I install the ClientConnector on a different machine than where Syntess runs?

Yes, you can install the ClientConnector on the same machine as Syntess or on another machine, as long as Syntess can reach the ClientConnector folders via a shared drive. The folders in Syntess must match the ClientConnector folders.
