In IBM Planning Analytics, making changes to financial models often requires experienced TM1 developers or IT support, delaying critical updates.
With OneStream, finance users are empowered to update and extend models directly through intuitive, no-code configuration tools like Cube Views, Forms, and Business Rules. This accelerates agility, supports real-time business needs, and reduces dependency on external technical resources.
✅ Finance-owned, not IT-owned
✅ Intuitive design and workflow tools
✅ Rapid model changes without redevelopment projects
TM1 models often become costly to maintain, requiring a small army of developers to make even minor enhancements.
OneStream consolidates planning, reporting, and analytics into one unified platform — minimizing the need for separate applications, complex scripts, or ongoing custom development.
✅ True platform consolidation = fewer moving parts
✅ Native version control and deployment tools
✅ Finance teams can maintain 80-90% of the solution without IT intervention
In TM1, system upgrades or model extensions can feel like massive projects.
OneStream’s Extensible Dimensionality® and Marketplace solutions allow organizations to adapt, expand, and extend their applications without starting from scratch or rewriting underlying models.
✅ Extensible Dimensionality® means models flex as the business changes
✅ Marketplace solutions allow rapid deployment of new functionality
✅ Upgrade paths are designed to be low-risk and non-disruptive
TM1 integrations often require heavy customization, middleware, and manual intervention, leading to data silos and inconsistencies over time.
TM1 environments typically require clients to build and manage a farm of individual data cubes, each representing different slices of the business. Keeping these cubes synchronized becomes an ongoing challenge — increasing risk, maintenance effort, and reconciliation work.
OneStream takes a fundamentally better approach: data is loaded once into a unified platform and is then available to all processes and models through Extensible Dimensionality. This eliminates the need for duplicate data structures and ensures all users work from a single source of truth.
✅ Direct ERP connectors (SAP, Oracle, NetSuite, Dynamics, and more)
✅ Centralized data integration and management inside OneStream
✅ No more cube farms: OneStream uses a true platform, not isolated cubes
✅ End-to-end data transparency with drill-back to source transactions
TM1 was built in a different era and it shows — both in the architecture and the shrinking pool of TM1 expertise.
OneStream is a modern, cloud-native platform built for today's finance teams — blending performance management, analytics, and AI/ML capabilities into a single, extensible solution.
✅ Cloud-native or on-premises options
✅ Continuous innovation with 2 major platform releases per year
✅ Growing ecosystem of OneStream-certified professionals and partners
IBM solutions often require stitching together TM1, Cognos Controller, Cognos Analytics, and other modules to meet enterprise needs.
OneStream delivers Planning, Financial Close, Consolidations, Reporting, and Analytics in a single platform, eliminating the need for multiple point solutions and integrations.
✅ One solution for the entire Office of Finance
✅ One user experience, one security model, one version of the truth
Need new functionality like Capital Planning, ESG Reporting, or Tax Provisioning?
OneStream's Marketplace offers 60+ downloadable, pre-built solutions, drastically cutting development time and cost compared to TM1's custom-build approach.
✅ Faster time-to-value
✅ Easily extend your platform without major consulting projects
TM1's multi-cube architecture struggles under large data volumes or complex models.
OneStream’s cloud-native, elastic platform supports massive enterprise deployments with high concurrency, low latency, and real-time data access.
✅ Reliable performance for global enterprises
✅ Future-proof infrastructure that grows with your business
TM1 offers limited audit tracking, making compliance burdensome.
OneStream provides complete audit trails across all data, metadata, user activity, and changes, helping organizations meet SOX, GDPR, and other compliance standards.
✅ Full transparency and traceability
✅ Streamlined audit processes for Finance and IT
TM1 often still relies on dated interfaces like Architect, Perspectives, or even Planning Analytics Workspace — which can feel clunky and outdated.
OneStream offers a modern, web-first user experience with customizable dashboards, dynamic reporting, and mobile accessibility.
✅ Easier adoption across the organization
✅ Reduces training needs and accelerates user productivity
Thousands of finance teams have modernized with OneStream to unify, simplify, and extend their performance management capabilities.
Experience a solution that empowers Finance — not IT — to drive change.
