What you cannot change on a Lago invoice without editing the template (self-hosted)

A few invoice elements are part of Lago's fixed PDF template and have no setting or API field, so they cannot be changed through Lago's configuration. On self-hosted you can edit the template's HTML directly to change them, but this is not recommended for the reasons below.

What is not configurable

The following cannot be changed through Lago settings or the API today:

• Renaming the "Units" column header in the line item table

• Changing the invoice layout or structure, including logo position, section ordering, and font

• Adding a text-only line item row that has no quantity or amount

The self-hosted template workaround

On a self-hosted deployment you can modify the invoice PDF HTML template directly in the codebase. Weigh this carefully before doing it: any template change has to be re-applied manually with every Lago version upgrade, and Lago support cannot help with problems that come from a modified template.
