Simplify your path to success with OneStream’s unified finance solution, delivered with PwC’s expertise
Take finance further with PwC and OneStream
Organisations in the midst of transformation or scaling, often face challenges in financial consolidation, planning, and reporting. Disconnected systems create data silos and inefficiencies, while manual processes increase the risk of errors and delays.

How can PwC help you
How can we help during the implementation of OneStream
We provide end-to-end consulting services in financial transformation and process optimization. From developing your financial strategy and selecting the best enterprise performance management system to OneStream design, implementation, training and ongoing system support, we guide you every stop of the way to ensure lasting success
During the design phase, we collaborate closely with your team to examine and co-design your current and future processes. Our consultants conduct in-depth workshops to map your existing financial workflows, identify inefficiencies, and define how OneStream can best support your desired way of working.
Together, we develop a robust data model that supports your evolving requirements — from multi-entity consolidation structures and chart of accounts harmonisation to planning hierarchies and reporting dimensions. We also assess integration requirements with your existing ERP and other operational systems to ensure seamless data flows.
Following this, we configure OneStream to align precisely with your business processes, tailoring workflows, business rules, calculations, and dashboards so the platform fulfils your financial consolidation, planning, and reporting needs from day one. Every configuration decision is documented and validated with your stakeholders to ensure full transparency and alignment
Successful technology implementation depends on more than just the platform — it requires people to embrace new ways of working. Our change management approach is designed to drive adoption from the outset, reducing resistance and accelerating time to value.
We start by conducting a stakeholder impact assessment to understand how the transition to OneStream will affect different roles across your finance, IT, and operational teams. Based on this analysis, we develop a tailored change and communication plan that keeps all stakeholders informed and engaged throughout the journey.
Our training programmes are role-specific and hands-on, combining instructor-led sessions, interactive workshops, and self-paced learning materials. We also create comprehensive documentation — including process guides, quick-reference cards, and video tutorials — so your teams have the resources they need long after go-live. Where needed, we redesign underlying business processes to fully capitalise on OneStream's capabilities, ensuring the new platform drives genuine operational improvement rather than simply replicating legacy ways of working
Our commitment to your success extends well beyond go-live. We provide ongoing technical support, performance optimisation, and continuous improvement services to ensure your OneStream solution keeps pace with your evolving business requirements.
In the initial weeks following deployment, our team conducts a hyper-care period — providing dedicated on-call support to quickly resolve any issues, fine-tune configurations, and address user questions as they arise in real-world use. We monitor system performance and data integrity to proactively identify and address areas for improvement.
As your organisation grows and your needs change, we help you unlock additional OneStream capabilities — whether that means extending into new planning areas, adding advanced reporting and analytics, or integrating with newly acquired entities. Through regular health checks and optimisation reviews, we ensure you continue to maximise the return on your OneStream investment and stay ahead of shifting regulatory and business demands.
