Integration methodConnection keys (Native API v3)DirectionSend + ReceiveMinimum subscriptionBasicContract requiredNo

With Accept, you can send and receive in 2026 e-invoices via eConnect. The integration works with connection keys and supports SimpleInvoicing version 2.0.

Before you start
  • An active eConnect account with at least a Basic subscription
  • Administrator access to your Accept environment
  • Your eConnect connection keys (App Key and Secret)
Setting up the integration
Step 1: Create connection keys

Create connection keys in the eConnect platform. Follow the steps in Creating connection keys.

Step 2: Configuration in Accept
  1. Start Accept and select the bookkeeping you want to connect.
  2. Go to Beheer > Administratie > Instellingen.
  3. Open the eFactuur folder and then eVerbinding (or eConnect, depending on the version).

  4. Configure the following values:
    • Check Gebruik API versie 3
    • Set SimpleInvoicing version to 2.0
    • Enter your email address used for eConnect
    • Paste the App Key and Secret
    • Optionally configure folders for purchase and sales invoices
    • Enter your Bedrijfs-ID (the XCNL or XCBE number from the platform)
    • Fill in your sender details (for country: NL)



  5. When using version 2.0: check Gebruik debiteur dossiernummer als KvK.
Step 3: Set up debtors

Configure the correct email address and identification number per debtor on the debtor card (Properties tab):

  • Government: enter the OIN number at FAX/OIN
  • Organization with Chamber of Commerce: enter the Chamber of Commerce number at Dossier/KvK nr
  • Without Chamber of Commerce: the platform automatically uses a dummy number (99999998)
Step 4: Send invoices
  1. Open the invoice in Accept.
  2. Verify that the correct email address is set for the invoice address.
  3. Click Uitvoer and select eFactuur > eVerbinding bericht.
  4. Confirm with Ja and type VERZENDEN.

Important: Do not include empty invoice lines, as this can disrupt processing.

After sending, you can find the Delivery ID on the "Extra" tab at the bottom of the invoice.
