E-Invoicing without ERP
Your ERP isn't ready yet —
but you are.
TaxLayer converts your existing PDF invoices immediately into legally compliant ZUGFeRD 2.1 and XRechnung — no ERP overhaul, no IT project, no waiting. The perfect interim solution until your system landscape is ready.
The Problem
E-invoicing mandate 2027 — but the ERP won't be ready in time
From 2027, all companies with over €800,000 annual revenue must send structured e-invoices in ZUGFeRD or XRechnung format. From 2028, it applies to everyone. Most ERP migrations take 6–18 months — too long to meet the deadline.
ERP project takes too long
Typical ERP transitions to e-invoicing take 6–18 months. The legal deadline won't wait.
Compliance risk is growing
E-invoicing errors risk fines and rejected invoices from customers.
Parallel operation is unavoidable
Not all locations, subsidiaries, or subsystems can be migrated simultaneously.

TaxLayer handles conversion while your ERP isn't ready yet — and remains as a parallel channel after migration is complete.

FAQ
ERP transition solution questions
We don't have an e-invoicing-capable ERP yet. How fast can we get started with TaxLayer?
Immediately. You upload your existing PDF invoices to TaxLayer — individually or in batches of up to 100 files at once (Enterprise). TaxLayer extracts all invoice data via AI, you briefly review, and download the finished ZUGFeRD or XRechnung file. No installation, no IT project.
Is TaxLayer only an interim solution or also usable long-term?
Both. Many companies use TaxLayer permanently alongside their ERP — for example, for invoices from subsystems, locations without ERP connection, or for quick processing of incoming supplier invoices. The decision is yours.
How long does an ERP migration for e-invoicing typically take?
Depending on the ERP system and customization needs, between 3 and 18 months. With TaxLayer, you bridge this time without compliance risk: all generated invoices are validated against EN 16931 and KoSIT schemas before being released for download.
Can we convert invoices from different source systems?
Yes. TaxLayer accepts any PDF invoices — regardless of which system they come from. Whether SAP, DATEV, Lexware, Word, or a custom layout: the AI extraction recognizes invoice fields regardless of format.
What happens with sensitive invoice data?
TaxLayer processes all PDFs exclusively in memory. Invoice contents are not permanently stored. Only metadata (timestamps, invoice numbers) are retained for 90 days for billing purposes. Hosting exclusively in Germany (Frankfurt), GDPR-compliant.
How much volume can TaxLayer handle?
In the Enterprise plan, up to 800 conversions per month. Batch upload of up to 100 PDFs simultaneously with parallel processing and automatic ZIP download. For higher volumes or API integration, contact us at info@landauer.de.
