CMB has always carefully selected its suppliers based on their capabilities and characteristics.

The Supplier Portal is the tool provided to businesses for accreditation and collaboration with CMB.

Work with CMB

CMB has made available the new SUPPLIER PORTAL to optimise the Vendor process. Supplier companies can use it to submit their applications, share information and qualification documentation, and access them all in one digital space for updating and consultation.

Qualification procedure

To access and request qualification in the OnlineProcurement Portal, follow these simple steps:

  1. Access the platform;
  2. Register and create your credentials;
  3. Create your profile.
  4. Enter the required information and upload the requested documents.

Once you have completed entering the necessary data according to your activity, the qualification request is submitted directly from the platform. You can temporarily suspend the entry of information and documents and resume later. The previously entered data will remain available when you log in again, while a special “box” indicates the progress of the procedure, as shown in the example below.


Request information and support

For information regarding the content and documents, please contact:

If you are having trouble creating your login credentials**, please contact the DigitalPA support service from the Portal’s homepage. Click on “CONTACT TECHNICAL SUPPORT,” and technical support will get back to you within 24 hours.


When creating a new user, the tax code and email address might already be filled in from existing personal data in the CMB database. In this case, you need to customise your credentials.

However, if the tax code is pre-filled with no associated email address, the system will prompt you to contact DigitalPA technical support for assistance.
