How to issue an electronic invoice (DIAN)

The electronic invoice validates the document with the DIAN and returns a CUFE. DeusRex issues it through its authorized provider, so you don’t have to set up credentials yourself.

Steps

1. Verify that your organization has electronic invoicing enabled and the NIT configured in Finance → Payment Settings.
2. Create the invoice with the service, the patient, and their affiliation.
3. Click Issue / Validate with DIAN.
4. Once accepted, the invoice displays its CUFE and is ready to download or send.

Tip

Services must have a CUPS code and the patient must have their health plan/coverage type up to date: both are required for the DIAN to accept the invoice.
