Feature Scope
Invoice Synchronization instead of Import
Deep integration instead of superficial import
<p>The Lexoffice WHMCS module offers deep integration between WHMCS and Lexoffice. Instead of just importing invoices, they are automatically synchronized. This means that even before WHMCS sends the invoice, the invoice is imported to Lexware Office.</p><p>The invoice behaves as if it had been created directly in Lexoffice.</p><p>Actions such as invoice cancellation and marking as paid are also synchronized from Lexoffice to WHMCS.</p><p>This also means that invoices sent by WHMCS will have the Lexware Office PDF attached. The Lexware Office PDF is not modified, so e-invoice features are preserved.</p>
Templating Engine for Invoices
Use extensive text and placeholders for the texts on your PDF invoice
Our module supports a comprehensive library of placeholders and text entry options. This allows you to display different text on the invoice for each payment method and language. The following placeholders can be used:
- Customer master data
- Invoice data
- SEPA pre-notification information
- Custom Fields
- Invoice fields including payment method
<p>You can find the complete list of all placeholders <a href="https://docs.becker-software.de/lexoffice-variables.html" target="_blank" class="text-primary-500">here</a></p>
