Service Level Agreements

We offer three different support packages with different service level agreements (SLA): an “Update and Maintenance Contract” that provides basic support, a “SILVER Package” gives priority support and a “GOLD Package” includes 24/7 support.

For an ideal support process

Customers with a valid SLA, or an hour based support package will be provided with an issue tracking system (support.celum.com) as well as phone support. However, for the best possible service we recommend reporting any issues by providing us with a detailed explanation and screenshots via our Support Portal.

If you purchased your CELUM solution from one of our partner companies, please contact your CELUM partner first.
