Invoicing

Invoices that survive the audit

Every invoice can produce ZUGFeRD 2.x XML and feed a DATEV-oriented CSV export, with reverse charge and account mapping configured per project instead of hard-coded.

In short

What does TixFin invoicing cover?

Invoicing is built into the platform for both the project side and the buyer side, with line items, overviews and document download. Each invoice automatically produces ZUGFeRD 2.x compliant XML in the EN 16931 profile (UN/CEFACT Cross Industry Invoice), stored per invoice and downloadable through a dedicated REST endpoint. Project teams export a DATEV-oriented CSV built from the stored invoice and line-item data, and a project-wide reverse charge flag applies § 13b UStG handling end to end.

  • ZUGFeRD 2.x XML generated per invoice

  • DATEV-oriented CSV export from real invoice data

  • Reverse charge under § 13b UStG, project-wide

Capabilities

Compliance without a second tool

  • 01

    ZUGFeRD 2.x XML

    UN/CEFACT Cross Industry Invoice in the EN 16931 profile with seller and buyer data, line items, tax indicators and reverse-charge codes, stored per invoice.

  • 02

    DATEV CSV export

    Download a DATEV-oriented CSV directly from the billing dashboard, built from stored amounts, tax rates, references, customer and seller data.

  • 03

    Reverse charge

    A project flag sets VAT to 0 %, adds the reverse-charge note to invoices, uses CategoryCode AE with an exemption reason in the XML and tags rows with [RC] in the export.

  • 04

    Account mapping

    Revenue account, contra account and cost centre are configured per project rather than hard-coded, and the CSV carries the extra columns to match.

  • 05

    Complete invoice model

    Customer VAT ID, address lines, postal code, city and country are first-class fields, so the document is complete without manual edits.

  • 06

    Compliance dashboard

    A dedicated billing tab collects reverse-charge configuration, DATEV account mapping, the CSV export and ZUGFeRD information in one place.

Invoicing

Straight from billing to bookkeeping

The export is wired into the existing invoice management and its permissions, so no separate back-office tool is involved. Admin, project and buyer views all read the same invoice records, which is what makes the accounting export trustworthy.

How it works

Getting books in order

  1. 01

    Fill the billing profile

    Seller data, bank details and the customer fields the invoice needs are maintained once per project.

  2. 02

    Configure compliance

    Set the reverse-charge flag if it applies and map revenue account, contra account and cost centre for DATEV.

  3. 03

    Sell as usual

    Invoices are created from real orders with line items, tax rate and references; ZUGFeRD XML is generated per invoice.

  4. 04

    Export

    Download the DATEV-oriented CSV, or pull ZUGFeRD XML per invoice through its REST endpoint.

FAQ

Invoicing questions

Ask the team

  • Yes. ZUGFeRD 2.x compliant XML in the EN 16931 profile is generated automatically for each invoice, stored alongside it and available for download through a dedicated REST endpoint.

  • Project teams download a DATEV-oriented CSV from the billing dashboard. It is built from the stored invoice and line-item data — amounts, tax rate, references, customer and seller details — and respects the existing invoice permissions.

  • Yes. A project-wide flag sets VAT to 0 %, adds the reverse-charge note to the invoice, uses CategoryCode AE with an exemption reason in the ZUGFeRD XML and marks the rows with an [RC] tag in the DATEV export.

  • No. Revenue account, contra account and cost centre are configured per project, and the CSV export includes the matching columns for reverse-charge marking and cost centres.
