Write an invoice –
fast and correct.

The mandatory details under §14 UStG

For an invoice to be recognized for tax purposes, §14 (4) UStG requires these details:

• Full name and address of you and your customer
• Your tax number or VAT identification number
• Issue date of the invoice
• A sequential, unique invoice number
• Quantity and type of the products supplied or scope of the service
• Time of the delivery or service (or the service period)
• The amount, broken down by tax rate, plus any agreed reductions (e.g. early-payment discount)
• The applicable tax rate and tax amount – or a note about the tax exemption

If a mandatory detail is missing, your customer can be denied the input VAT deduction – and you have to correct it. Software that checks these details before finalizing saves you exactly this hassle.

Special case: small businesses (§19 UStG)

As a small business you don't charge VAT – instead, a note belongs on the invoice, such as: “Pursuant to §19 UStG, no VAT is charged.” BILLEVO has the §19 small‑business scheme built in as a toggle and saves it per receipt – switching the scheme later doesn't break your old invoices.

E-invoice: what applies since 2025

Since 1 January 2025, companies in Germany must be able to receive e‑invoices; the obligation to issue e‑invoices yourself follows in stages through 2028. An e‑invoice isn't a PDF, but a structured format under EN 16931 – in Germany primarily ZUGFeRD/Factur‑X and XRechnung.

BILLEVO does both out of the box: create (externally validated with veraPDF, KoSIT and Mustang), receive, check and archive in a GoBD‑aligned way – at no extra charge.
