AP Automation for the German E-Invoice Mandate: CANDIS, Spendesk, and Moss Compared
Germany's 2027 sending mandate isn't just about generating structured invoices — it's about automating the receipt and processing of incoming XRechnung and ZUGFeRD invoices too. We compare three AP automation tools popular with German SMEs.
Most coverage of Germany's e-invoicing mandate focuses on sending structured invoices — choosing between XRechnung and ZUGFeRD, validating formats, setting up the right software.
But there is an equally important, less-discussed side: receiving and processing incoming e-invoices from suppliers at scale. This is where Accounts Payable (AP) automation tools come in.
Why AP Automation Matters for the German Mandate
From January 2025, your suppliers can already send you XRechnung and ZUGFeRD invoices. From January 2027, many of them will have to. If you receive 50+ supplier invoices per month, manually processing incoming structured XML invoices in your accounting software is a significant bottleneck.
AP automation tools extract the data from XRechnung and ZUGFeRD invoices automatically, match them against purchase orders, route them for approval, and post them to your accounting system — without manual entry.
CANDIS (Germany)
Website: candis.io Founded: 2015, Berlin Pricing: From €199/month (SME plans) Target: German SMEs, 10–500 employees
CANDIS is a German AP automation platform built specifically for the German accounting workflow. It accepts XRechnung and ZUGFeRD 2.3 invoices via email, direct upload, or API, and integrates natively with DATEV.
What CANDIS does well:
- Native DATEV export — your accountant or Steuerberater benefits directly
- Automatic extraction from ZUGFeRD embedded XML (no OCR, direct parsing)
- Approval workflow that meets GoBD audit trail requirements
- German customer support
Limitations:
- Germany-focused — limited support for FatturaPA or Peppol
- Higher price point than simple accounting tools
- Requires a DATEV-connected accounting firm for full benefit
Spendesk (Germany / France)
Website: spendesk.com Founded: 2016, Paris (strong German and French market presence) Pricing: From €99/month (Starter) Target: Startups and scale-ups, 10–500 employees
Spendesk is a spend management platform that handles AP automation as part of a broader expense and spend control suite. It supports XRechnung and ZUGFeRD on the receiving side and has a French module for Factur-X.
What Spendesk does well:
- Multi-country support: Germany + France in one platform (useful if you operate in both)
- Modern UI — popular with tech-forward companies
- Corporate card management + invoicing + AP in one tool
- Peppol-ready architecture for Belgium/Netherlands invoicing
Limitations:
- Less deep German accounting integration than CANDIS
- Not optimised for businesses with complex VAT scenarios
- Steeper price at higher tiers
Moss (Germany)
Website: getmoss.com Founded: 2020, Berlin Pricing: From €99/month Target: German startups and growth companies, 5–200 employees
Moss positions itself as a German Spendesk alternative with a strong focus on spend visibility and German-language UX. AP automation for incoming XRechnung and ZUGFeRD invoices is supported, with DATEV integration.
What Moss does well:
- Fully German-language — no translation needed
- Corporate cards + AP automation + expense management
- DATEV native export
- Competitive pricing for the feature set
Limitations:
- Newer platform — less proven than CANDIS for high-volume invoice processing
- International coverage limited to German and Austrian markets
- Some enterprise features still in roadmap
