Three documents, two companies and one brand

A group uses one public brand for two legally separate Swiss companies. An accepted order identifies Alpha AG as purchaser, while the later supplier invoice names Beta GmbH and the delivery note refers only to the brand. The employee preparing payment assumes that common management makes all three designations legally identical. A commercial-register extract in the folder is several years old, and the proposed signatory's current role has not been confirmed. The exercise does not provide enough facts to decide every contractual or representation issue. It asks the accounting team to identify which information and evidence must be reconciled before recording and paying the transaction, rather than inventing a legal result from an address or a shared logo.
