The Hidden Cost of Legacy FP&A Systems
Introduction
Legacy FP&A platforms often appear stable on the surface—but beneath that stability lies growing cost and complexity. Many finance teams are paying significantly more each year just to keep outdated systems running.
The True Cost of Maintaining Legacy FP&A
- Support and maintenance costs
- Resource requirements
- Upgrade and infrastructure expenses
What once seemed cost-effective can quietly become a financial burden.
Complexity and Knowledge Gaps
As systems age, organisations often lose the in-house knowledge needed to manage them effectively. This increases reliance on external consultants and makes even simple changes time-consuming and costly.
Vendor Pressure and Upgrade Fatigue
Many FP&A vendors push customers toward new versions or replacement products with higher price tags and lengthy implementation timelines—often without delivering meaningful improvements in agility or efficiency.
