Tax Exemptions
You can now create Tax Exemptions and assign them to tax rules.
This is especially important for e-invoicing, as invoices with a 0% tax rate must include a valid Tax Category Code and a Tax Exemption Reason Code to be considered compliant.

With this feature, you can define your own Tax Exemptions and link them to existing tax rules to ensure correct tax classification and compliant invoice creation across different countries and regulations.

This improves validation, reduces rejection rates from tax authorities, and ensures your e-invoices meet mandatory legal requirements. Learn more.
Expert Mode for Document Provisioning
The Webportal now offers an Expert Mode for document provisioning configuration.
When enabled, an additional JSONATA field becomes available, allowing advanced routing logic based on custom conditions.

This enables complex use cases such as:
• Routing based on invoice amount thresholds (e.g. only apply rule if amount > 250)
• Industry- or region-specific routing logic

All JSONATA conditions are evaluated within the Document Provisioning Service and are also respected by the e-invoicing workflow, ensuring consistent behavior across all document formats.

This enhancement increases flexibility and supports advanced compliance requirements.
Default Jsonata Mapping for E-Invoicing Configurations
When creating a new e-invoicing mandate, a default JSONata mapping is provided automatically. This helps you get started faster without having to build the mapping from scratch.
Added Business Segments to OPOS-Cases
We added visibility of business segments in the OPOS cases to support correct account splitting and posting.
Billing Run Control per Customer (API only)
You can now enable or disable the billing run for individual customers directly via API. This allows you to perform complex corrections without generating intermediate credit notes, reducing the number of correction documents created during ongoing adjustments. When the billing run is disabled for a customer, no billing documents will be generated until the run is reactivated.
Bug Fixes
1. We fixed a bug where some required mappings for a correct ZUGFeRD invoice were missing, such as Payment Instructions (BG-16 / BT-21) and Payment Reference (BT-83).
2. Fixed an issue where tax rules with a classification were incorrectly applied even when no valid customer tax classification existed.
Announcement instellix Rebranding
As part of the rebranding of our company from Nitrobox to instellix, the webportal will undergo a rebranding in the coming weeks to reflect our new brand identity. This includes adjustments to colours, typography and visual elements to align them with our revised design and vision for the future. Stay tuned.
1. As part of the instellix rebranding, we are also refining the user interface to make it cleaner and more intuitive. To keep frequently used actions easy to access while reducing visual clutter, we will introduce a consistent “three dots” action menu across the webportal. Actions that go beyond the standard options like viewing, editing, or deleting are no longer shown as separate buttons. Instead, these additional options can be found by clicking the three‑dots icon next to the relevant item, which opens a small menu with all available actions for that context. This helps the interface feel more modern and organized, while ensuring that all familiar actions remain easy to find.
