Simplifying operations, accelerating insight, and scaling for what’s next

Rebuilding the core: How PwC is reshaping finance with SAP Cloud ERP

Hero image

PwC is transforming its finance function by moving to SAP S/4HANA Cloud—replacing fragmented legacy systems with a single, unified platform. Standardized processes and automation are simplifying how we work, accelerating insight, and helping us scale AI and innovation with confidence. That momentum started early with AI speeding up design and build through pre-developed documentation. Now, it’s helping drive rapid code and prototype development post go-live.

One firm. One platform.

What sparked the need for change?

Our finance landscape kept evolving—and so did its complexity. Independent member firms. Legacy SAP systems. Third-party tools. Heavy customization. Each made sense on its own. But together, they made it harder to get a clear, connected view of performance. Over time, our people started to feel it. Decisions took longer. Scaling took more effort. And technical debt built in the background. Upgrades became bigger and more complex. Meanwhile, the bar was rising. We needed to move faster and do more with our financial data—like unlocking new capabilities, including the latest AI tools. But the path wasn’t as straightforward as expected.

What solution did the teams unlock by working together?

PwC moved to SAP S/4HANA Cloud to bring finance operations together on a single, unified platform. But the real shift was how we chose to get there. We turned to the same PwC teams that help our clients implement and scale. And, instead of rebuilding legacy processes, our teams used SAP’s native capabilities to reduce customization and simplify the system at its core.

That decision helped reshape how our finance function operates. Workflows are now standardized across countries. Automation is embedded across finance and project operations. And data is consistent, connected, and easier to act on. Beyond the S/4 core, we simplified the data landscape—retiring disparate databases and moving to a more unified approach. The result: a foundation that’s simpler, more transparent, and built to scale.

Where did tech innovation meet human ingenuity?

Standardization became a turning point. But it wasn’t about eliminating flexibility—it was about maintaining a clean core while simplifying solutions. Introducing customization only where it addressed critical business needs. Teams aligned across countries, reducing complexity and letting go of fragmented reporting in favor of a smaller, consistent set of utilization metrics and calculations.

Where it mattered more, targeted extensions enhanced the platform. A custom SAP Business Technology Platform simplified how revenue is split across project leaders, while SAP’s Business Data Cloud capabilities enabled that data to flow quickly across the landscape for profitability analysis and forecasting. This balance—standard where possible, tailored where it counts—reshaped what the platform could support. Now, we’re positioned to adopt new SAP capabilities, including AI-driven tools, as they’re released and without disruption. Innovation isn’t something we add later. It’s built in.

What was the real-world impact of approaching things differently?

Today, PwC operates on a unified, cloud-based finance platform across 19 countries. Processes move faster, controls are stronger, and visibility extends across the business. PwC’s own Application Evolution Services (AES) for SAP team is supporting and evolving the platform, leveraging AI to automate and reduce reliance on manual work. But the bigger shift is what’s now possible. We can scale AI, adopt new capabilities quickly, and keep evolving how finance supports our business. And that impact extends beyond finance—making it easier to bring these capabilities to clients with greater speed, clarity, and confidence.
