Professional Support

The Document Foundation does not provide professional support services for LibreOffice. It does, however, develop and maintain a certification system for professionals of various kinds who deliver and sell services around LibreOffice. The details of the certification programme can be read on the Certification page.

Certification is available for:

  • LibreOffice developers, providing either feature development services or Level 3 Support (bug and regression fixing)
  • Professional consultants, supporting migration projects from proprietary office suites to LibreOffice, or deployments of LibreOffice in large organizations
  • Professional trainers, providing training on LibreOffice at basic, intermediate and advanced level

If you are interested in their services, the list below shows our certified developers and professionals - with their affiliation - in alphabetical order.
