FAQs about Candis
No. Candis is listed on the DATEV Marketplace and supports the Accounting Data Service and the Invoice Data Service. Your tax advisor continues to work in DATEV. Candis transfers the prepared data so that the existing process remains unchanged.
Yes. Candis has a direct interface to SAP Business One and Microsoft Business Central, including goods invoices and three-way matching. For systems without a standard interface, the Candis interface is available.
Candis documents every step in the process: which accounts were suggested, who approved, and which rules are stored. This knowledge remains in the system, regardless of who operates it. New team members get up to speed based on the actual workflows, not verbal handovers.
Yes. Candis receives, validates and processes XRechnung and ZUGFeRD, including the legally required XML archiving as the leading dataset. The obligation to receive e-invoices has applied since 1 January 2025 for all domestic B2B transactions.
All data is stored on servers in Germany, with no transfer to third countries. Candis enters into a data processing agreement and meets the requirements of the GDPR. A complete list of sub-processors is available on request.
That depends less on volume than on how many processes are currently running in parallel. If invoices, credit cards, expenses, contracts, and travel expenses are managed in different tools or spreadsheets, the effort arises regardless of invoice volume. In the initial call, we clarify together whether the switch pays off for your setup in concrete terms.
Candis AI makes suggestions, it does not post entries on its own. Every account assignment is reviewed and approved by your team before it is transferred to the accounting system. Responsibility stays where it belongs: with the people who know the process.
Candis has a deputy rule with an out-of-office note. Approvals are automatically forwarded to the assigned deputy, with no manual intervention and no delays in the process.
