Finance transformation is never just a technical upgrade.  A recent D365 Finance & Operations implementation delivered by PSP demonstrated how moving away from a legacy finance platform is also an opportunity to strengthen controls, reduce manual effort and introduce more consistent operational processes across the organisation.

The client was transitioning from Microsoft Dynamics GP to D365 F&O.  The goal was not to replicate the legacy system but to design a finance solution that better supported the business while remaining close to standard D365 F&O functionality.

This approach was deliberate.  Heavy customisation can introduce unnecessary complexity, increase testing effort and make future upgrades more difficult.  The project therefore focused on understanding the finance requirements thoroughly, designing an effective Chart of Accounts, and configuring D365 F&O in a way that supported the business without adding avoidable technical debt.

PSP’s Finance Business Analyst worked closely with the client to gather requirements, review existing processes and support the design of the new Chart of Accounts.  Although the solution was built around a single legal entity, it needed to support all business areas.  The design had to be clear enough for day‑to‑day processing while also structured enough to support reporting, controls and future growth.

Once the design was agreed, the team progressed through build, testing and QA.  This included validating core finance processes, ensuring workflow and approvals behaved correctly, and confirming that the solution could support real operational scenarios rather than isolated system tests.

One of the most significant changes was the introduction of a formal purchase order process.  Previously, payment could occur before full authorisation was completed in the finance system.  D365 F&O enabled the client to adopt a more controlled approach, with workflow, approval routing and three levels of authority.

This represented a major cultural shift.  The change affected not only the finance team but the wider business. Staff who were used to informal approval routes now needed to raise purchase orders correctly, follow structured approval paths and ensure authorisation was completed before payment.

To support adoption, PSP delivered training to 12 finance users and 75 business owners involved in raising and approving purchase orders. Finance teams needed to understand core D365 F&O processes, while operational teams needed clarity on how purchase orders, approval routes and authority levels would work in practice.

The new workflow structure provided clearer ownership, improved visibility of commitments and reduced reliance on manual or informal processes.  For finance teams, this is where D365 F&O delivers real value embedding governance directly into everyday operations.

Integration was another key focus.  The client’s existing processes between Dynamics CRM and finance relied heavily on manual input, exports and imports.  PSP introduced integrations to reduce manual activity and create a more reliable flow of data between CRM and D365 F&O.

This reduced duplication, lowered the risk of manual error and created a stronger foundation for reporting. It also supported a more unified operating model, where finance data could be processed and controlled consistently across systems.

The project demonstrated that successful D365 F&O implementations rely on more than technology alone. The platform is important, but the real value comes from strong process design, structured configuration, thorough testing and effective change management.

For organisations moving from Microsoft Dynamics GP or other legacy systems, the opportunity extends beyond system replacement. It is a chance to reassess how finance operates, introduce stronger controls, reduce manual processing and build a platform that supports future growth.

This project showed that keeping the solution simple, controlled and close to standard D365 F&O functionality can deliver meaningful transformation. With clear requirements, well‑designed approval structures, targeted training and reliable integrations, finance transformation can improve not only the system but the way the business works.
