"Finance tool built for finance and owned by finance"
5/5
What do you like best about OneStream - Unified EPM?

OneStream is easy to use for Finance professionals. The implementation was easy and the use of the consolidation tool has improved our close process by reducing the hours spent, but also improving the level of confidence we have in our monthly results. Finance owns the product and any changes we need to make, we can implement without IT involvement. Review collected by and hosted on G2.com.

What do you dislike about OneStream - Unified EPM?

We still have work to make our forecasting process easier and smoother. Right now we still are leveraging Excel to do much of our forecasting, but are in the process of looking for a better option within OneStream. Review collected by and hosted on G2.com.

"Flexible Software for many Financial, Reporting, and Operational Needs"
4.5/5
What do you like best about OneStream - Unified EPM?

More features are continually added to keep up with the changing financial landscape and new technologies to allow our team to use the newest technologies for additional efficiencies.

What do you dislike about OneStream - Unified EPM?

The UI on the desktop app feels relatively outdated, and the terminology can be difficult to understand. Extendable dimensionality took me a long time to understand even with the training provided online, so it would be nice to see additional basic training to help new users get acquainted with the software.
