You connect QicsMilestones to eConnect in 2026 via connection keys. After the integration, sales invoices are sent directly from QicsMilestones via Peppol. A useful feature of this integration is that the UBL format is configurable: you choose whether invoice lines are sent in detail per line or grouped per VAT code.

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

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

Step 2: Set the UBL format

Before connecting the provider, set the desired invoice format:

  1. Go to Company settings and open the Invoicing tab.
  2. Choose the desired format under Invoice data format:
    • Standard: regular invoice format
    • UBL: detailed per invoice line
    • UBL - grouped by VAT code: invoice lines summarised per VAT rate

The grouped format is useful for recipients who process invoices automatically by VAT code. The detailed format is suitable when the recipient wants to see all individual invoice lines.

Step 3: Set up the provider
  1. Go to the Digital provider tab in Company settings.
  2. Select eVerbinding as the provider.
  3. Enter the Key and Secret from the eConnect platform.
  4. Enter the email address of your eConnect account.

Step 4: Set up per customer

Set the sending method per customer to the digital provider:

  1. Open the customer card and go to the Invoicing tab.
  2. Set Invoice sending method to Digital provider.

Sending invoices

After the integration, sending invoices works as follows:

  1. Create a sales invoice in QicsMilestones as usual.
  2. When the invoice is finalised, it is automatically submitted via eConnect.
  3. eConnect sends the invoice via Peppol to the recipient.
  4. The delivery status is visible in your eConnect Outbox.

Tip: Don't forget to set the sending method to Digital provider for each customer. Customers for whom this is not set will not be sent via eConnect.

Frequently asked questions
What is the difference between UBL and UBL grouped by VAT code?

With the standard UBL format, all individual invoice lines are sent. With UBL grouped by VAT code, invoice lines are summarised per VAT rate. The grouped format is useful for recipients who process invoices automatically by VAT code.

Are invoices sent directly via Peppol when finalised?

Yes, after the integration, sales invoices are automatically submitted via eConnect when finalised and sent via Peppol to the recipient. The delivery status is visible in your eConnect Outbox.

Do I need to set the sending method per customer?

Yes, for each customer you set the sending method to "Digital provider" on the customer card under the Invoicing tab. Customers for whom this is not set will not be sent via eConnect.
