For buyers contracting authority
Reach for 48783000 when the contract supplies a content management software package, the CMS product and its licences, rather than a system built or run as a service. Web CMS, intranet, and digital-portal platforms belong here when the licence and the product are what gets bought.
The boundary that most often trips contracting authorities is document management. Document management software package (48311000) is the right pick when the core job is filing, versioning, and access-controlling documents rather than authoring and publishing content. The same supplier product can blur the line, so set the primary CPV code by the dominant purpose: publishing content points here, governing documents points to 48311000.
Two more neighbours sit close. The parent, System, storage and content management software package (48780000), is the better tag when the scope spans system and storage management broadly and content management is not the main thing. The sibling Storage management software package (48782000) is for managing where data physically lives, not the content layer on top. Where one contract bundles the CMS licence with configuration and a few years of support, tag the primary code by the dominant deliverable.
