Become a supplier

Start collaborating with the Enel Group

1. Registration

The first step in becoming one of our suppliers is to register your company on the WeBUY platform.
You can then begin the qualification process, consult the tenders and qualification notifications from the Group, take part in tendering, manage contracts, submit invoices and check the performance appraisals for your company.

2. Qualification

The Qualification process permits the selection of suppliers that meet the essential requirements for collaborating with the Enel Group, in keeping with our values and strategic vision.
There is a single supplier qualification system for the whole Enel Group and it takes the form of assessing the technical, economic/financial, environmental, safety, human rights, legal, ethical and reputational requirements for the company.
Qualification is specific to the Merchandise Groups (MGs) for which each company proposes its supply. It may be local or global depending on the individual MG and is valid for five years.

3. Participation in purchasing procedures.

Carrying out purchasing procedures digitally allows us to optimize the process in terms of simplification, transparency and paper reduction. This is why through WeBUY we provide our suppliers with the appropriate tools to enable the exchange of all documentation electronically, while guaranteeing its security and legal validity.

4. Invoicing and VAT Group

Sending invoices in electronic format through the WeBUY portal makes it possible to reduce transmission time and activate the immediate registration process, through the information in the digital layout. It is possible, at any time, to know the processing status of sent documents.

In addition, effective January 1, 2021, Enel established the "VAT Group" for the Group's Italian companies.
