"Top Tier CPM System"
4.5/5
What do you like best about OneStream - Unified EPM?

OneStream is an incredibly dynamic corporate performance management system that can integrate nearly all source systems into one unified platform. There is great out-of-the-box functionality, but what is great about OneStream is seemingly limitless customization can be built on it. This allows for precise customization regardless of the customer and their needs. Additionally, the MarketPlace is constantly evolving, expanding, and growing based on customer/consultant feedback. Review collected by and hosted on G2.com.

What do you dislike about OneStream - Unified EPM?

It's difficult to find a true dislike about OneStream, but if I had to pick one, I would say that I wish some of the MarketPlace Solutions were a little more robustly built out-of-the-box. An example would be that the People Planning module didn't have a lot pre-built that we could build upon. Review collected by and hosted on G2.com.

"Implementation"
5/5
What do you like best about OneStream - Unified EPM?

What I like best about OneStream is having one, consolidated platform for access. It's so easy to enter and access the value added data without spending time wasting through data and tieing out data from multiple platforms. The one source of truth and reliability of the data is amazing. Integrating with our ERP is going better than I expected, especially since we are on a smaller, less known ERP. Review collected by and hosted on G2.com.

What do you dislike about OneStream - Unified EPM?

Not sure yet...trying to learn the full system is a little overwhelming at first but I'm sure as soon as I go through the online training's I'll feel better. Review collected by and hosted on G2.com.

"OneStream - New User"
4.5/5
What do you like best about OneStream - Unified EPM?

What's most helpful about OneStream is the unified platform and the use of extensibility. By having all data in one platform, such as actuals, plan, and operational data, users are able to access in one system. Extensibility enables users and groups to have the flexibility to view and/or plan data in different ways. Review collected by and hosted on G2.com.

What do you dislike about OneStream - Unified EPM?

With all the options available in OneStream, the user experience may seem overwhelming without the proper support of the Admins and super users. Review collected by and hosted on G2.com.
