Note: Receiving foreign B2B invoices is not active by default. Candis sets up the receipt individually for each foreign company. You cannot activate the receipt yourself in the settings.
What Candis handles for you
Candis uses a platform that is already connected to the national e-invoicing networks and to the receiving channels that individual countries prescribe. Your foreign company receives its invoices through this platform, and Candis picks them up from there.
The platform receives the e-invoice in the prescribed network of the respective country. You meet the requirements of that country through this connection.
Candis handles the forwarding: the invoice arrives in the inbox of the respective company in Candis — in the same inbox as German documents.
Further processing stays unchanged: invoice data, accounting data, approval and export work like they do for any other invoice.
Countries and deadlines at a glance
The following overview shows in which countries an obligation to receive domestic B2B invoices applies or is coming up.
Information as of September 2026.
France
The reform took effect on 1 September 2026. Since that date, all companies must be able to receive e-invoices, regardless of their size. The obligation to issue applies since 1 September 2026 for large companies and mid-sized companies (ETI), and from 1 September 2027 for PME and micro-enterprises. The exchange runs through an approved platform (Plateforme Agréée, PA for short) in a structured format such as Factur-X, UBL or CII.
Poland
The obligation to use the state platform KSeF applies to domestic B2B since February 2026 and was extended in April 2026 to all VAT-registered companies. All companies registered for VAT in Poland must issue and receive invoices through KSeF; paper and PDF invoices are no longer permitted for domestic B2B. KSeF uses the FA(3) format and not Peppol.
Belgium
The mandatory B2B e-invoice applies since 1 January 2026, with EN 16931-compliant formats via the Peppol network.
Italy
The obligation applies since 1 January 2019 for all VAT-registered companies and since 1 January 2024 for micro-enterprises as well. All invoices run through the SdI platform in the FatturaPA format.
Croatia
The start was planned for the beginning of 2026, following a test phase from September 2025.
Spain
Spain relies on the national VERIFACTU system. The start originally planned for early 2026 was postponed; mandatory use is expected to take effect in 2027.
Slovakia
Voluntary use starts in 2026, the obligation follows in 2027.
Finland, the Netherlands and the Nordic countries
There is no comprehensive national B2B obligation so far, but Peppol is widely used on a voluntary basis.
Germany
The obligation to receive applies since 1 January 2025. From 1 January 2027, the transition rule for issuing ends for companies with more than 800,000 euros in revenue in the previous year; from 1 January 2028, the obligation to issue applies to all domestic B2B invoices.
Note: The national timelines change regularly. Which countries Candis currently supports, and whether your case is covered, is something you clarify with Candis Support.
Step 1: What you clarify in advance
Collect the following for each foreign company:
Country and the date from which the obligation to receive applies
Company name, address and EU VAT ID
The national company identifier, for example SIREN or SIRET for France
Does a Peppol ID already exist?
Does a registration with a prescribed platform already exist, in France for example with an approved platform (Plateforme Agréée)?
Tip: An existing Peppol ID or platform registration often runs through the ERP system or the tax advisor of the foreign company. Ask there if you do not know the current status.
Step 2: Contact Candis Support
Contact Candis Support with the information you collected. Support clarifies the next steps with you.
