Sitoo is a Swedish cloud-based point-of-sale and unified commerce platform for retailers. It connects in-store and online sales channels, with functions for inventory, click & collect and a single customer view. The company describes the product as cloud-native software-as-a-service aimed at larger retailers. No self-hosted or open-source edition is mentioned on the company's website.
Sitoo AB is headquartered in Stockholm, Sweden, and was founded in 2004 under a different name. The sources reviewed do not name a majority owner, so this text does not state one. The company's website mentions the use of Amazon Web Services without naming a region. Sweden is an EU member state, but for a European organisation the hosting location of customer data should still be set out in the data processing agreement.
