# BH-PROFILE-01 — Reduced profile (MINIMUM/BASIC WL)

> https://billhorse.com/en/rules/bh-profile-01/

## What does this error mean?

MINIMUM and BASIC WL are not EN 16931 conformant e-invoices — they only serve as booking aids.

## How to fix it

For mandate compliance generate at least BASIC, ideally the EN 16931 (Comfort) profile.
