Case Study Series #1: How a US Pharma Innovator Brought Clarity to its Investment Portfolio.

Dearest readers, allow me to confess, the most fascinating tales are the ones no one initially meant to tell. Consider this the opening of our Elysys Client Use Case Blog Series, a bi-monthly dive-in into real deployments, real challenges, and the moments when Microsoft Copilot for Business Central provides natural-language inquiry over financial data, automated journal suggestions, anomaly detection on transaction patterns, and document summarisation. Copilot is invoked directly from within Business Central pages and operates against the same role-based security model as the underlying records.e the right tool changes everything.

For the first edition we're heading to the USA. A leading oncology company, already running Microsoft Business Central. A growing investment portfolio with no dedicated home inside their ERP. And a Microsoft partner who knew who to call.

Today we're diving into how Elysys stepped in, not to replace what was working, but to extend it. What followed was an on-site deployment, a custom built tax module, and a finance team that stopped reconciling investments manually for good.

Ready? Let's get into it

Client Presentation

Our client is a US-based oncology company specialising in the research and development of treatments for illnesses. They operate on Microsoft Dynamics 365 Business Central across a 200+ user organisation, and manage a portfolio of equity holdings, private equity funds, and financial instruments requiring rigorous investment accounting.

Before Elysys

Already running on Business Central through a Microsoft partner, the client had no dedicated investment management layer. Tracking equity positions, private assets, and complex financial instruments was handled manually or outside the ERP, with no automated calculation of taxes, valuations, or returns.

Why They Engaged With Elysys

Centralise investment Data

Manage all equity, PE, and fixed income positions within one platform, directly integrated with Business Central.

Automate Complex Calculations

Automate deferred tax calculations, coupon accruals, and FX rate imports, to eliminate manual errors.

Real-Time Portfolio Reporting

Deliver CFO-ready dashboards giving a full view of portfolio allocation, performance, and risk exposure.

Extend via a Trusted Partner

Brought in by Microsoft partner, Elysys integrated seamlessly into an existing Business Central environment, no disruption, no migration.

The Elysys Solution

Elysys deployed Elysys Wealth and Elysys Analytics directly on top of the client's existing Business Central environment, with no migration, no disruption. The team configured the platform on-site at the client's Princeton office, delivered tailored power BI reporting, and developed a bespoke Deferred Tax calculation module to meet the client's specific US compliance requirements. Elysys Financial Gateway was also activated to automatically import live FX rates from central bank and market data providers.

Results & Benefits

Built around the client, not the other way around

From on-site implementation in Princeton to a custom-built Deferred Tax module, Elysys adapted at every step. The platform shipped to fit the client, not the client forced to fit the platform.

Investment accounting, finally inside the ERP

Equity, PE, and fixed income positions now managed directly within Business Central, with no parallel systems or manual reconciliation.

Portfolio clarity at a glance

Finance team and leadership access real-time dashboards in Power BI showing full portfolio allocation by asset class, geography, and instrument type.

That's a wrap on our first use case. Same time in two months, different client, different challenge, same eagerness to get it right. See you then.

FAQs

What does it mean to add investment management software onto an existing ERP system?

Adding investment management software onto an existing ERP means the new functionality installs directly into the ERP's existing data model, rather than running as a separate connected system requiring ongoing data migration or synchronisation. This keeps financial data in one place instead of splitting it across a core ERP and a disconnected specialist add-on. Elysys is an example of a platform built this way, running natively on Microsoft Dynamics 365 Business Central.

Can investment accounting software handle jurisdiction-specific tax requirements like deferred tax?

Yes, on platforms designed for it, jurisdiction-specific calculations such as deferred tax can be developed as dedicated modules that sit alongside standard investment accounting, rather than being handled manually outside the system. This keeps tax treatment consistent with the rest of an organisation's financial records instead of introducing a separate manual process. Elysys has developed custom tax modules of this kind for clients with specific compliance requirements.

How does investment accounting software keep foreign exchange rates current?

Accurate valuation of multi-currency positions depends on up-to-date FX rates, so reliable software imports live rates automatically from central bank and market data providers rather than requiring manual entry. Elysys Financial Gateway is one example of a tool that performs this import automatically.

What does a practical example of ERP-native investment accounting look like?

In practice, it means a single environment where equities, private equity holdings, and financial instruments are tracked, valued, and reconciled using the same general ledger as the rest of an organisation's finances, with no manual export or import step between systems. Elysys applies this model on Microsoft Dynamics 365 Business Central.
