Customer invoicing for Redmine with German/European e-invoicing built in.
Turn approved timesheets (from at_zeiterfassung) and manual line items into
compliant invoices, and issue them as EN 16931 e-invoices — ZUGFeRD hybrid PDF
or XRechnung — without leaving Redmine.
E-invoicing (EN 16931 / ZUGFeRD / XRechnung)
- Every invoice is produced as a hybrid Factur-X / ZUGFeRD 2.x PDF: a
human-readable PDF with the structured invoice XML embedded, so one single
file serves both people and accounting systems. This is what the German B2B
e-invoicing rules (mandatory receipt of structured invoices since 2025) ask
for on the sending side.
- Semantic standard EN 16931 over UN/CEFACT Cross Industry Invoice (CII, D16B).
- Selectable profile per installation:
• ZUGFeRD EN 16931 (Comfort) — default
• ZUGFeRD BASIC
• XRechnung 3.0 (CIUS over CII) — for public-sector (B2G) recipients
- XRechnung mode emits an XRechnung-3.0-compliant document with seller and
buyer contact data and the Leitweg-ID (BT-10 Buyer reference) required for
B2G. Correct profile URN and the mandated BT business terms are set.
- Per customer you choose the format: ZUGFeRD, XRechnung, or none (plain PDF).
- Download the hybrid PDF (with embedded factur-x.xml) or, for portals such as
ZRE/OZG-RE, the pure XRechnung XML.
- Reverse-charge and VAT handling reflected in both the PDF and the XML.
Invoicing
- Customer master data — company, address, VAT ID / tax number, IBAN/BIC,
default rate, payment terms, currency, contact (salutation/first/last name)
- n:m customer ↔ project mapping; build invoices from a customer + period,
with TimeEntry rows grouped by user/project/issue (select a whole project at
once), priced via Redmine rates or a customer override, plus manual items
- Per-project approval gating: by default only approved hours are billable
- Configurable invoice numbers — free-form format with {{…}} placeholders
(e.g. {{customer_prefix}}-{{year}}-{{seq}}), giving a separate gap-free
running number per customer/year (DB-locked); per-customer prefix and start
number
- Per-invoice editable texts (cover / closing / legal), pre-filled from the
settings, frozen on issue; draft PDF preview with watermark before issuing
- Configurable multi-column business-letter footer (bank, commercial register,
managing directors); logo; layout and color options
- States draft → issued → (partially_paid) → paid, plus overdue and cancelled
via a reverse invoice per § 14 UStG / GoBD (issued invoices are never deleted;
cancelling releases the billed time for re-invoicing)
- Optional time-entry appendix (Leistungsnachweis) as a PDF attachment
- Email dispatch with configurable sender address and signature, HTML body,
and additional attachments
- Payment tracking with automatic state transitions and overdue detection
Permissions: view invoices, manage invoices, manage customers.
English and German. Requirements: Redmine 5.1+ (tested on 6.x). GPL v2.
Best paired with at_zeiterfassung for approved-time invoicing.
