Invoice-Converter vs PDF24

PDF24 offers an online e-invoice generator for formats such as XRechnung and ZUGFeRD. Invoice-Converter is built for teams that already receive PDF invoices and need extraction, review, compliant output, and validation guidance in one workflow.

PDF24 suits freelancers and very small businesses that occasionally type an invoice into a free online form. Invoice-Converter is built for accounting teams that keep their existing ERP or billing software and need a repeatable way to turn the PDFs it produces into validated XRechnung or ZUGFeRD files: extraction, human review, and KoSIT-aligned validation in one workflow, without re-keying data.

To be clear about when PDF24 is the better choice: if you only create a handful of invoices and are fine entering them manually, PDF24 is cheaper. Invoice-Converter pays off when invoices already exist as PDFs or mixed inputs, volumes recur, and rejected submissions cost you time.

Frequently Asked Questions

Should I use PDF24 or Invoice-Converter?

Use PDF24 when you want a form-based generator or general PDF tools. Use Invoice-Converter when the invoice already exists elsewhere and you need a reviewable PDF-to-XRechnung or ZUGFeRD workflow with validation guidance.

Is PDF24 enough for XRechnung compliance?

For occasional invoices that you enter manually, yes: the PDF24 generator can produce XRechnung and ZUGFeRD files. You stay responsible for correct field content, and troubleshooting validator findings (for example KoSIT BR-DE rules) is largely up to you. If you convert existing PDFs at volume and need explained validation results plus a review step, a dedicated converter is the safer workflow.

Can PDF24 convert an existing PDF invoice to XRechnung?

PDF24 lets you import a PDF into its generator, but you typically complete and check the structured fields yourself. Invoice-Converter extracts the data from the PDF, shows it for review, and validates the XRechnung or ZUGFeRD output against the format rules. Neither tool removes the need to review edge cases and low-quality scans.

Is Invoice-Converter a paid product?

Yes. Use credits or a subscription depending on your volume and workflow needs.
