The inbox view lists all received invoices with format, dates, amounts and a validation status badge.
Since 1 January 2025, all businesses in Germany must be able to receive electronic invoices (e-invoices) under § 14 UStG. By 2027/2028 they must also issue them. Most existing tools require uploading sensitive supplier data — amounts, VAT IDs, bank details — to a third-party cloud service. itdatex E-Invoice Intake does the work locally inside your own WordPress installation.
The free version performs all processing locally on your own server. No data leaves your WordPress installation. There is no telemetry, no automatic update check against a third party, no analytics, no external font or asset loading.
A separate Pro version (sold via wp.itdatex.support, not part of this free plugin) adds optional cloud-assisted features — KoSIT deep validation, AI-based error explanations in plain German, IMAP auto-import, DATEV export — and is opt-in only.
The plugin supports GoBD-conformant processes through immutable storage, SHA-256 hash chaining and a complete audit trail. Note that software cannot be “GoBD-certified” — conformity is a property of your process, not of any single tool. Consult your tax advisor for the specifics of your setup.
The full source code is released under GPL-2.0-or-later. You can verify, audit and adapt the plugin yourself. Dependencies (josemmo/einvoicing for UBL, horstoeko/zugferd for CII/ZUGFeRD) are vendored with prefixed namespaces so they cannot conflict with other plugins in the same WordPress installation.
