COMMEO is a modular B2B commerce platform for mid-sized companies, offered by Allgeier (Schweiz) AG in Thalwil. It goes beyond an online shop: it shows product catalogues with variants and configurable products, reads customer-specific prices and tiered pricing directly from the ERP and offers a customer portal with order history, several addresses and staff accounts. Standard connectors exist for SAP, Microsoft Dynamics, PIM and CRM systems and B2B standards such as OCI and Datanorm. A headless CMS, multilingual operation (DE, EN, FR, IT) and a REST API are part of the platform. The vendor handles implementation, hosting and service.
Allgeier (Schweiz) AG is based in Thalwil, Switzerland, an EFTA country with an EU adequacy decision. According to its website it is a subsidiary of Allgeier SE, an IT services group headquartered in Munich. COMMEO is hosted on Microsoft Azure, but no region is stated, so Switzerland is assumed; ask which region holds your data. Microsoft is a US company, so the US CLOUD Act can apply even to European regions. Self-hosting is not described.
