CANDIS Review 2026: AP Automation for XRechnung & ZUGFeRD Receipt Processing

CANDIS is not an invoicing tool — it is an accounts payable automation tool. The difference matters. While sevDesk, easybill, and Lexware help you send structured e-invoices to customers, CANDIS helps you receive and process structured e-invoices from suppliers.

With Germany's 2027 sending mandate arriving, many businesses are focused on generating XRechnung and ZUGFeRD. But by 2027, you will also be receiving hundreds of structured invoices from your suppliers. Processing them manually in your accounting software is a significant bottleneck. CANDIS automates that bottleneck.

Why AP Automation Matters for the German Mandate

Here is the workflow problem CANDIS solves:

Without AP automation (today):

1. Supplier sends XRechnung XML by email
2. Your accountant downloads the XML attachment
3. They manually open it in a text editor or viewer
4. They manually enter the invoice data into DATEV or your accounting software
5. Someone manually approves the invoice for payment

With CANDIS:

1. Supplier sends XRechnung XML by email to your CANDIS inbox
2. CANDIS automatically parses all mandatory fields from the XML
3. The invoice appears in CANDIS with all fields pre-populated
4. Your approval workflow triggers automatically (e.g., >€5,000 requires CFO approval)
5. CANDIS pushes the booked invoice to DATEV automatically

Step 3–5 requires human judgment (approval, account assignment). Steps 1–2 are fully automatic.

Setting Up CANDIS for XRechnung and ZUGFeRD

Email Inbox Setup (15 minutes)

CANDIS gives you a dedicated invoice email address (e.g., invoices@yourcompany.candis.io). Instruct suppliers to send e-invoices here. CANDIS processes:

• XRechnung XML files (attached to email)
• ZUGFeRD PDF files (CANDIS extracts the embedded XML from the PDF/A-3 container)
• Standard PDFs (processed via OCR — less accurate than structured formats)

The XRechnung and ZUGFeRD extraction is immediate and fully automatic — fields are parsed directly from the XML without OCR. Invoice number, amount, VAT rate, supplier IBAN, and payment due date appear instantly in your CANDIS inbox.

DATEV Integration

CANDIS's DATEV integration is its strongest differentiator. After you review and approve an invoice in CANDIS:

• The posting (Buchungssatz) is pushed to DATEV Unternehmen Online
• The original XML or PDF is archived in DATEV DMS
• The accounting entry uses the correct DATEV account codes (which you map once in setup)

Your Steuerberater (tax advisor) sees the booked invoices in DATEV exactly as if they had been entered manually — without any additional work from their side.

Approval Workflow

CANDIS's approval routing is flexible:

• Amount-based routing: Invoices above a threshold require a specific approver
• Cost centre routing: Invoices coded to certain cost centres go to the relevant manager
• Supplier-based routing: A specific supplier's invoices always go to the same person
• Escalation: If no action within X days, escalate to the next approver

This is genuinely useful for growing businesses where one person no longer approves everything.

GoBD Compliance

Germany's GoBD requirements for invoice archiving require:

1. Invoices archived within a defined timeframe
2. Archives tamper-proof and immutable
3. Audit trail of all changes and approvals
4. 10-year retention period

CANDIS's archive meets all four requirements. Every action — import, review, edit, approval, posting — is logged with timestamp and user. The invoice file itself is immutable from import. The audit log can be exported for tax inspector review.

Important: CANDIS stores archives in German data centres (Frankfurt) and holds ISO 27001 certification — both relevant for GoBD and GDPR compliance.

What CANDIS Does Not Do

To be clear about scope:

• Does not generate outgoing invoices — you need a separate tool for sending XRechnung/ZUGFeRD to your customers
• Does not handle payroll or tax filing — pure AP automation only
• Does not connect directly to Peppol as a receiving endpoint — invoices must come via email or direct upload
• Not suitable for < 50 invoices/month — the ROI of €199/month requires meaningful volume

Pricing

Plan	Price	Included invoices/month	Users
Starter	€199/month	100 invoices	5 users
Growth	€349/month	300 invoices	15 users
Scale	Custom	Unlimited	Unlimited

At €199/month for 100 invoices, the cost per invoice is €1.99. If each invoice currently takes 10 minutes to process manually at a cost of, say, €25/hour, the payback threshold is roughly 8 invoices per month. Above that, CANDIS saves money.

Verdict

CANDIS is the best-in-class AP automation tool for German SMEs with DATEV-connected tax advisors. If you are receiving 50+ structured invoices per month, the automation genuinely pays for itself.

The €199/month entry price is not cheap — but for businesses it is aimed at (10–500 employees, DATEV-connected, volume > 50 invoices/month), it is appropriate.

CANDIS is right for you if:

• You receive a significant volume of supplier invoices each month
• Your tax advisor uses DATEV
• You want GoBD-compliant archiving without additional setup
• You need approval workflows for invoice authorisation

Consider alternatives if:

• Your primary need is sending structured invoices (not receiving) → use sevDesk, easybill, or Lexware
• You have fewer than 50 incoming invoices/month → manual processing or a cheaper tool may suffice
• You need multi-country AP (Germany + France + Italy) → consider Spendesk or Pagero
