The Hidden Costs of Legacy ERP: How Outdated Systems Impact Your Bottom Line

Henry Sack • Jan 02, 2024

Many businesses rely on legacy ERP (Enterprise Resource Planning) systems implemented years or even decades ago. While these systems once fulfilled their role, they've often failed to evolve alongside the company's changing needs. CFOs are increasingly discovering "hidden costs" associated with relying on antiquated technology –  expenses eroding profitability and hampering company growth that may not be immediately obvious.


ERP Deployment Options

Legacy/On-premises ERP

These systems are installed and maintained on your company's own servers. While they may have offered control in the past, they are notorious for high IT overhead, slow upgrades, customisation difficulties, and increasing security risks – the very issues our article highlights.


True Cloud ERP

Modern SaaS (Software as a Service) ERPs like NetSuite operate in the cloud. The vendor takes care of updates, maintenance, and security, easing the burden on in-house IT. These solutions bring agility, real-time accessibility, and streamlined costs, often a direct solution to the issues created by legacy systems.


Hybrid ERP

In some cases, businesses opt for a blend. It could be due to specific regulatory needs or wanting to retain direct control over highly sensitive data while moving other functions to the cloud. However, hybrid models still add some complexity for management.


Hidden Costs of On-Premise ERP and Perpetual Licensing Arrangements

Opportunity Costs and Lost Productivity

Outdated ERPs are notorious for inefficiencies. Cumbersome manual processes, slow performance, and a lack of automation force employees to spend valuable time on basic tasks like data entry and reconciliation. This translates to missed opportunities for innovation and higher labour costs.


The Upgrade Treadmill

When business requirements change, legacy ERPs struggle to adapt. Instead of supporting new growth avenues, they become restrictive. Companies end up paying for expensive customisations and third-party integrations just to maintain business as usual. Often, they lack the ability to seamlessly connect with newer, best-in-class solutions.  Contrast this with modern cloud ERPs, designed to be flexible and updated constantly to keep pace with business innovation.

Contrast this with modern cloud ERPs, designed to be flexible and updated constantly to keep pace with business innovation.

The Spiralling Costs of IT Maintenance

As legacy systems age, they require substantial upkeep. Specialised IT professionals may be needed, their knowledge becoming scarcer as technologies become outdated.  Businesses become heavily reliant on these resources for troubleshooting and updates, incurring further cost burdens. Cloud-based ERP systems shift this responsibility to the vendor, reducing on-premise infrastructure costs and headaches for internal IT teams.


Security Breaches and Compliance Fines

The outdated security infrastructure of legacy ERP systems poses a growing risk of costly data breaches. Without timely security patches or modern safeguards, sensitive information becomes vulnerable.  Further, failure to adhere to evolving regulatory standards can lead to significant fines.  NetSuite, for example, is regularly audited and maintained to the highest security and compliance standards.


Lost Business Opportunities and Hampered Growth

Slow decision-making processes caused by reliance on inaccurate or outdated data in an ERP can directly impact  the ability to seize promising opportunities. "Running the business without having a source of truth - or any reliable source of truth, for that matter - was extremely difficult. NetSuite changed everything,” notes Rachel Berg, VP of Business & Services Operations at Boosted Boards.  Without scalable processes offered by modern ERPs, expansion becomes strained and expensive, putting competitors at an advantage.


The True Cost of Outdated Systems

It is crucial for CFOs to look beyond the direct expenditures of maintaining a legacy ERP system. When you factor in wasted productivity, increasing  IT costs, security risks, compliance hazards, and missed growth opportunities, the true cost of doing nothing becomes staggering. It's time to consider how a modern ERP like NetSuite can bring agility, cost savings, and a platform for long-term success.


The Benefits of Modern Cloud ERP

While legacy ERP systems present numerous obstacles, the shift to a modern, cloud-based platform like NetSuite unlocks tremendous value and addresses many of the pain points we've discussed:

Freedom from Infrastructure Worries

Say goodbye to maintaining servers, software updates, and backups. Cloud ERPs offload this responsibility, reducing IT headaches and the significant expense of owning and updating in-house hardware. This directly saves you on the often-overlooked costs of internal IT resources dedicated to the system.


Effortless Customisation & Evolution:

Gone are the days of being trapped by costly customisations made to an outdated system. Cloud ERPs are designed for flexibility with modular structures and low-code/no-code options, allowing businesses to adapt and tailor the system as needs change  This ensures your operations aren't hamstrung by a  static ERP as your company grows.


Agility and Seamless Updates

New features and improvements are constantly rolled out automatically. Imagine the savings gained from not having to pay for major upgrade projects on legacy systems! Your team always works on the latest, most secure version, minimising costly security risks and keeping you at the forefront.

Real-Time Data & AI-Powered Insights

Say goodbye to manual data wrangling and delayed decision-making. Cloud ERPs deliver real-time access to vital business metrics across departments, allowing for instantaneous insights to fuel proactive choices. Advanced analytics embedded in platforms like NetSuite help predict trends and automate processes that lead to smarter business decisions, not just better reports.


Streamlined Implementation

Modern ERP implementations don't have to be disruptive nightmares. Cloud ERPs often incorporate streamlined, phased approaches that minimise disruptions to ongoing operations. Users get acquainted gradually,  improving collaboration and ensuring a smooth transition. Contrast this with the costly and risky 'big bang' upgrades often the only option with legacy systems.


The Bottom Line Advantage

Switching from legacy ERP to a cloud-based system addresses "hidden costs". Imagine freeing up IT resources from constant maintenance, eliminating security patching anxieties, accelerating processes with real-time data, and avoiding upgrade disruptions.  Modern ERPs aren't just a technology change, they're a transformation empowering CFOs to streamline operations and drive financial efficiency.


Fake Cloud vs. True Cloud: Not All Solutions Are Equal

The term "cloud" sometimes creates confusion. Here's the distinction:



Fake Cloud:  Some vendors host a modified version of their on-premises software in a data centre and label it "cloud." While this shifts physical server maintenance, it often fails to deliver the scalability, agility, and innovation expected from true cloud solutions.


True Cloud ERP: A system designed from the ground up for the cloud, like NetSuite, offers multi-tenancy with shared infrastructure, making upgrades seamless and costs predictable. These platforms are inherently flexible, accessible from anywhere, and optimised for continuous advancement.


The Case for Change

If managing these 'hidden costs' is a constant concern, moving your ERP to the cloud promises transformative benefits. Cloud-based ERP systems like NetSuite free businesses from the operational and financial burdens of legacy solutions. This empowers CFOs to redirect resources towards innovation, agility, and, ultimately, stronger overall business performance.
