E-invoicing from the CRM you already use
An electronic invoice contains structured data that other systems can process. Generate XRechnung from the invoice you created in Vtiger, then share the XML file with the recipient.
Less manual invoice work
Use customer and invoice data already in Vtiger to generate machine-readable XML. Check the file, email it to the recipient and keep a record of what was sent.

Map the external invoice number
Choose which Vtiger field supplies the invoice number written
to the exported e-invoice. This helps when your official
business number is stored in invoice_no instead
of the default invoiceid.
When to change the mapping
-
Your recipient or external system expects the official
number from
invoice_no. - Your Vtiger installation uses a different numbering convention from the internal record ID.
- You want the XRechnung number to match the number shown in your existing invoice process.
The setting changes the exported number. It does not require a database change.
Configuration example
In the module configuration file, set the external invoice
ID field to invoice_no:
$ITS4YouEInvoice_Fields = [
'id' => 'invoice_no',
];
Save the file and clear the Vtiger cache if needed.
The extension then uses vtiger_invoice.invoice_no
as the external invoice number.
Existing installations retain their current behavior until the mapping is changed. The mapping mechanism can support additional fields in future versions.
Keep your accounting software
Vtiger issues and sends electronic invoices while your accounting application continues to handle bookkeeping. Share received XML files and a CSV overview with your accountant without re-entering the issued invoice in another system.
Your existing workflow
Create an invoice once in Vtiger and produce the structured XRechnung XML from that record.
Provider connection when needed
Sending XML by email does not require a provider account. Provider-based delivery or reception requires a compatible provider under a separate contract.

E-Invoice and XRechnung FAQ
Answers to common questions about the Vtiger extension.
What is the difference between an e-invoice and a PDF?
A structured e-invoice contains machine-readable data. An ordinary PDF sent by email is a visual document and does not by itself contain the required structured invoice data.
Can I generate XRechnung from Vtiger?
Yes. Generate XRechnung XML from an existing Vtiger invoice, including credit notes. Validate the XML and check the recipient's delivery requirements.
Can I send an X-Rechnung XML file by email?
Yes. Attach the exported XML to an email. Ask your recipient whether email is an accepted delivery method for that invoice.
Can I validate an E-Rechnung XML file?
Yes. Export the XML and use one of the external validators linked above. Correct any reported errors in the invoice data, then export and validate again.
What is the difference between invoiceid and invoice_no?
invoiceid is the internal Vtiger record ID.
In many installations invoice_no holds the
business invoice number. Since version 4.5, you can configure
which field is mapped to the external invoice number.
Can I receive electronic invoices in Vtiger?
Incoming e-invoices can appear in a readable inbox with search, filters and internal processing states. Receiving requires the appropriate provider connection and configuration.
Is ZUGFeRD / Factur-X supported?
In development. Hybrid PDF generation with PDF Maker and reading incoming CII / ZUGFeRD invoices are planned additions.
Which Vtiger versions are compatible?
The extension is compatible with Vtiger CRM 8.x. Contact us if you need to confirm a specific installation.
Are einvoice and erechnung different products?
No. E-invoice is the English term for an electronic invoice; E-Rechnung is the German term. XRechnung is a specific structured format used in German invoicing workflows.
