Are there any functional differences between the cloud and on-premises versions?

No. The cloud version and on-premises version of DocuWare share the same codebase and offer the same functionality. We call this “no-compromise cloud” because many other document management and workflow products provide a limited or restricted feature-set in their cloud version. DocuWare does not. The difference is only the deployment and financial models. DocuWare Cloud is subscription-based software as a service (SaaS) and delivered as on-demand cloud services. DocuWare on-premises can be installed in your data center and delivered as a local application or through a private cloud.
