This is an PDF-Template for [Invoiceplane](https://www.invoiceplane.com/) a self-hosted open source application for managing your quotes, invoices, clients and payments.
You can add a "Leistungszeitraum" for any invoice by defining the two custom date fields: `Leistungszeitraum-Anfang` and `Leistungszeitraum-Ende`. These will not be shown on the invoice if either is not set.
You can also add a description text for the full invoice by adding a text custom field called `Beschreibung`.
