FAQ
Should I use the department name or the full organization name?
Use the full legal name of the organization that is contractually responsible for the purchase. Department information can be included in additional buyer fields or contact details.
How should I handle public administration names?
For German public administrations, use the complete official name (e.g., "Bundesministerium der Finanzen", "Stadt München"). Avoid abbreviations unless they are part of the official name.
What about subsidiaries and branch offices?
Use the name of the specific legal entity that is purchasing. If it's a subsidiary, use the subsidiary's name, not the parent company's name.
