OneStream · Advisory & Delivery

OneStream advisory & delivery.

Implementation, model architecture, source-system integration, and ongoing optimisation for OneStream consolidation and planning environments.

What we deliver
Consolidation implementation: entity structure, eliminations, intercompany matching, and currency translation, architected for your structure
Planning model design unified with your consolidation data model, so finance plans and closes from the same numbers
Source-system integration: ERP and GL feeds reconciled into OneStream, with full evidence trails
Migration from legacy consolidation platforms, run as a parallel-close exercise until the numbers match exactly
What we deliver

Services across the OneStream environment.

Consolidation Build

Entity structure, elimination rules, intercompany matching, and currency translation, designed before any configuration begins, since these decisions are expensive to change after go-live.

Planning Model Design

Budgeting, forecasting, and operational planning models built on the same data model as consolidation, so finance never reconciles between two systems.

Reporting & Account Reconciliation

Management reporting and automated reconciliation workflows configured against your actual close calendar and entity structure.

Integration

ERP and GL feeds connected and reconciled into OneStream, with documented data lineage from source to report.

Migration from Legacy Platforms

Parallel-run migration from an existing consolidation tool. Your old and new numbers proven to match before we cut over reporting.

Optimisation & Support

Audits and rebuilds of underperforming OneStream models, plus ongoing support once your team is trained to run it independently.

How we work

A clear process. No surprises.

01

Scope the engagement

We review your current systems, consolidation requirements, and close calendar to define exactly what the build needs to cover before any design work begins.

02

Design the architecture

Entity structure, elimination rules, intercompany logic, currency translation, and planning model designed before any configuration begins. These decisions are expensive to change after go-live.

03

Deliver and hand over

Fully documented implementation, finance team training, and reconciliation evidence before we close, built on the same zero-delta standard we apply to every EPM engagement.

Our architects bring hands-on delivery experience across OneStream, Workday Adaptive Planning, Oracle EPM Cloud, and Anaplan, which is what lets us move quickly on integration and data architecture decisions that span more than one system.

Frequently asked questions
What does a typical OneStream consolidation rollout actually involve?

Entity structure and elimination logic design first, followed by intercompany matching rules and currency translation setup, then a parallel run against your existing close process until the numbers reconcile exactly. Only once that reconciliation is proven do we cut over reporting to the new platform. This sequencing is what prevents a close-cycle disruption during migration.

Can you migrate us off our existing consolidation tool without disrupting reporting?

Yes, with proper migration planning. We treat this as a parallel-run exercise, building and reconciling the new consolidation logic against your existing process until it matches exactly, before cutting over reporting to the new platform.

What does an engagement include once we go live?

Full documentation of the consolidation logic, reconciliation evidence against your prior close process, and a finance team trained to operate the platform independently. We also offer ongoing support for teams that want an architect on call as their requirements evolve.
