Overview
Investing in ERP is a big bet. There are high stakes; there are risks, but the ROI makes the gamble worthwhile. Nowadays, ERP isn’t just infrastructure; it’s an engine for growth, agility, and intelligent decision-making. Modern ERPs are no longer “systems of record” but “systems of innovation”.
In fact, high-growth and ambitious businesses rely on enterprise resource planning (ERP) software to automate almost all aspects of their processes, from inventory, warehousing management to procurement, supply chain, risk management, and accounting.
Moreover, the global ERP market is expected to reach $239.2 billion by 2032 (Statista), which means that this is the digital transformation era and keeping up is no longer a choice; it is vital to thrive.
We understand that finalizing the decision to move to ERP is a win in itself. But getting to this level of automation requires stakeholders to make critical decisions.
Standing at the crossroads? To go the on-premises ERP route, take the cloud path or go hybrid? Most CEOs and CFOs would agree that it’s a complicated question. At first glance, all options seem confusing.
Of course, in the AI age, your ERP strategy would drift towards cloud ERP. But, learning the pros and cons of on-premise, cloud and hybrid ERP can make you certain of your investment and give you more confidence. Let’s begin.
Understanding ERP Deployment Models
ERP deployment models determine how the ERP software is hosted and accessed by users. Broadly, the three main deployment models are:
- On-Premise ERP
- Cloud ERP
- Public Cloud
- Private Cloud
- Hybrid ERP
Each model offers unique advantages and trade-offs in terms of cost, scalability, control, and customization. This isn’t a one-size-fits-all answer. What works for a high-growth D2C brand may be wrong for a legacy manufacturing giant. What suits a lean startup may hinder a regulated enterprise.
So, remember: this decision between on-premise, cloud and hybrid ERP is not just about technology; it’s about strategic survival in a lightning-paced market landscape. It is not about what other competitors are doing, but what is best for YOUR niche, industry, and business. Keep exploring ERP deployment models as we break down each one in-depth.
On-Premise ERP – What Is It?
On-premise ERP systems are deployed in your company’s data center, run on its server, and installed in your business facility. They do not need the internet; they can be accessed via the internal web. The installation and maintenance of the hardware and software is done internally by your company, and all data, infrastructure, and apps are hosted on-site. In other words, on-prem ERP is the one where you own the system, hardware, and data management.
While today’s generation is all about the flexibility, scalability and innovative power of cloud ERP, some companies in highly controlled industries which require heavy security and have more stringent compliances still opt for on-premise as their go-to ERP deployment approach.
-
Advantages of On-Premise ERP
Fully Customizable: On-premise ERP systems can be easily tailored to the unique workflows of a business. Cloud ERP may have customization limitations or require extensive customization capabilities and heavy investment, but on-prem ERP systems can be tailored and adapted to business-specific processes.
Complete Control: Some businesses operate in highly regulated industries (e.g., defense, finance, healthcare, pharmaceuticals). On-premise ERP assures greater control over the data, apps, and systems infrastructure. All hardware and software can be internally managed and integrated with existing systems, which makes the ERP advantageous for organizations with stringent security requirements.
In-house Governance and Data Security:You control patching, security and data backups in the case of on-prem ERP. Companies can implement security and privacy measures as per their needs, ensuring adherence to their industry-specific norms and internal policies. Since no third party is involved, there is less chance of breach or cyberattack.
One-time Cost:On-premise ERP has a fully paid, one-time upfront cost for purchasing and installing the software and hardware. While the initial investment cost is on the higher side, it may be lower in the long-term compared to recurring subscription costs associated with any cloud ERP. Upfront costs also mean businesses with stable budgets can deploy ERP with long-term planning.
-
Drawbacks of On-Premise ERP
High Upfront Investment: On-premise ERP is CapEx-heavy, which means servers, infra, hardware, licenses and skilled IT personnel to manage and maintain the system require a substantial initial financial commitment. This proves disadvantageous for smaller enterprises with limited or growing capital.
Slow to Scale: Expanding geographically or across business units is hard.
In-house Maintenance Overload: On-premise ERP systems require dedicated IT teams for updates, patches, system maintenance, and data security. The dependency on human capital can hamper the speed of work and ROI of ERP adoption.
Expandability, A Challenge:Scaling an on-premise ERP system can be challenging and expensive. Add-on features or users often mean buying new licenses, hardware and software – which can be time-consuming, complex, as well as costly.
Lengthier Implementation TAT:On-premises ERP implementations usually take longer compared to cloud ERP. This means organizations can miss out on the latest functionalities and system improvements.
Thus, on-prem ERP systems are ideal for businesses that seek complete oversight over their ops and have strict regulations. For example, a large ammunitions manufacturer producing explosives for the nation’s Armed Forces would have to keep specifications a secret, highly customized processes and equipment tightly integrated, vendor and customer information confidential, records in-house, as well as data as per government rules. They may not be allowed to use cloud storage in the first place. Such a company would need highly tailored on-prem ERP to help them automate every process – while still keeping classified data secure.
Example of On-Premise ERP Deployment:
A leading industrial machinery and concrete solutions company went from legacy to SAP ECC 6.0 on-premise, eliminating data silos and driving better reporting capabilities. With over 20,000 machines in operation, SAP ECC 6.0 helped with streamlined workflows, deeper insights, and elevated process control. The implementation was completed in just 7 months by Uneecops team, and the company now leverages sharper performance across finance, customer behavior, and inventory.
Cloud ERP – What Is It?
Cloud ERP is offered as software-as-a-service (SaaS); meaning this enterprise resource planning software can be accessed via internet and installed by a software provider who handles the end-to-end implementation, support, maintenance, upgrades and innovations, data storage, and security of the business management solution. In simpler words, cloud ERP helps manage mission-critical operations and is hosted in a shared cloud computing environment by a vendor. That is why Cloud ERP is also referred to as SaaS ERP. All apps within a Cloud ERP can scale up or down automatically to meet evolving business needs.
Customers are not owners of the software; they can lease cloud ERP based on their requirements via yearly or monthly subscriptions. There are no upfront hardware costs – and the software provider takes care of the working of the application.

Why Is Cloud ERP Preferred by Most Modern Businesses?
Be it public or private, Cloud ERP is now the go-to backbone for fast-scaling, future-focused businesses. Why are businesses adopting cloud ERP?
- Because when ERP was introduced in 1990s, it was on-prem, legacy. It was only a means to manage business processes using companies’ data and servers. But in the 2000s, came the cloud ERP disruption – and the narrative changed completely since.
Many companies resisted change, stuck to their age-old on-prem systems and perception of cloud ERP being unsafe for data security. However, dismissing cloud ERP added the hidden ‘tech debt’ to such companies. Ultimately, they ended up paying more for outdated ERP with limited scalability, customizability, or innovation.
Today, the reasons to switch to cloud-based ERP are far more compelling. In fact, this is no longer the generation of tech installation; it is the generation of tech strategy and tech adoption to stay abreast and innovate in a digital future.
- The transition to cloud ERP powers digital transformation, disrupts old business models and radically elevates the role of CIOs, CTOs and CEOs in leading IT departments.
- And, importantly, now cloud ERP systems deliver advanced technologies like artificial intelligence (AI) and machine learning to enhance productivity and service, tailored user experiences to drive adoption; and wide-ranging functionality and embedded analytics to provide a complete view of the business, ultimately supporting business innovation and growth.
- Cloud ERP is agile; it supports your business as it expands into new locations, launches new products and services, or adds new workflows. This flexibility and expandability assure that businesses never need to change their backbone ERP; only add-on new features as they grow – and at the pace of their growth!
- With OCR and intelligent automation, cloud ERP reduces transactional clutter and frees teams to focus on analysis, performance, and growth-driven decisions.
- From CFOs to front-line managers, users can access live performance dashboards across devices, transforming how decisions are made on-the-go, not just at month-end.
- With automated journal entries, integrated data sources, and prebuilt financial reports, cloud ERP dramatically shortens the month-end close, giving finance teams time back for strategic insights.
- Cloud ERP evolves with changing regulations: from global revenue recognition standards (IFRS 15, ASC 606) to local tax laws, helping ensure compliance is proactive, not reactive.
- Cloud ERP comes pre-configured with audit-ready templates, enabling smarter risk management, tighter role controls, and reduced fraud exposure, without drowning in spreadsheets.
- Cloud ERP simplifies multi-country operations, with prebuilt localizations for tax, legal, and financial requirements, cutting down setup time and compliance risks.
Today, business leaders need to interpret what’s happening in their business and act on that insight in real-time to succeed. Cloud enables such action. In the AI times, the winners will be those organizations that leverage cloud-based ERP digitization to scale profits and multiply ROI.
- Because when ERP was introduced in 1990s, it was on-prem, legacy. It was only a means to manage business processes using companies’ data and servers. But in the 2000s, came the cloud ERP disruption – and the narrative changed completely since.
Public Cloud ERP
Public cloud ERP is hosted, owned, handled and operated by third-party cloud service vendors, and the server/storage is delivered via the internet. It is a shared setup with multiple organizations, where all software, hardware, network devices and storage are used by customers like a cloud tenant.
-
Advantages of Public Cloud ERP
Standardized services: Solutions are not custom-made, but you always have the option of certain add-ons at additional cost.
Quick setup: Public ERP helps businesses automate operations and streamline enterprise-management fast, as it is quick to launch. This means lower TCO and higher ROI!
Pay-as-you-go pricing: When you do not need in-house infrastructure or maintenance, your ERP becomes cost-effective. You pay for what you use!
No upkeep hassle: Security, updates, maintenance, optimization, and performance are managed by the vendor.
Infinite ERP scalability: Hire in-house or external ERP resources on-demand as your business grows.
High dependability: A diverse network of servers makes changes of failure less likely.
Example of Public Cloud ERP
SAP, the world leader in ERP systems, offers Grow with SAP S/4HANA Public Cloud, which is also called Grow with SAP for businesses seeking ERP-powered digital transformation with agility, resilience and rapid deployment. It is cost-effective and comes with industry-standard built-in best practices.
SAP also offers RISE with SAP Public Cloud (SAP S/4HANA Public Cloud) that assures innovation with global scalability.
Here’s why SAP Public Cloud is the best Public Cloud ERP:

-
Drawbacks of Public Cloud ERP
Limited customization: Complete tailoring of the ERP workflows as per your niche is not possible. Only add-on modules can be configured. However, even add-ons cannot be fully personalized for your unique requirements.
Less control: Shared cloud means reduced visibility of your hosting setup, data storage and cloud security measures employed by your vendor.
Software provider lock-in: Migrating to a new cloud vendor can prove to be significantly complex as well as costly.
Compromised security: In case of data breach or infra corruption, it affects every organization sharing the database.
Private Cloud ERP
In a private cloud ERP, the infrastructure, storage, and services are maintained and deployed to a single organization. The software provider offers dedicated application hosting via the internet. Now, you may be wondering about the difference between on-premises and private cloud ERP. While on-prem ERP is deployed internally in a company’s infra, private cloud ERP can be hosted internally or through a third-party provider, but the environment is not shared with other organizations.
Private cloud ERP can be accessed by users using a remote app and an optional VPN for security.
This setup allows flexibility in licensing; you can either purchase perpetual licenses and own the software outright or opt for a subscription model like public cloud services.
It’s an ideal choice for businesses that require high-performance infrastructure with enhanced security and data privacy, offering strong adaptability and flexibility to meet evolving operational needs.
-
Advantages of Private Cloud ERP
Best of public cloud ERP + on-premises ERP: Solutions are not custom-made, but you always have the option of certain add-ons at additional cost.
Data security: You can rest assured as data is private in your company’s isolated landscape and the chances of corruption are lesser as compared to public cloud (as data is maintained independently and is only accessible to certain authorized users).
Easy upgrades and customizations: Private cloud users can upgrade functionalities to suit their needs and growth trajectory. Private cloud ERP can also be customized on the terms and timeline of the company.
Employ vendor and offload maintenance: Your in-house resources are freed from upkeep.
Full control: You retain complete control over infrastructure, updates, configurations, and customizations.
Compliance: Easier to meet industry-specific compliance and regulatory requirements, thanks to customization and isolation.
Example of Private Cloud ERP
SAP is a prominent leader in enterprise solutions. Rise with SAP S/4HANA Cloud Private Edition under SAP’s RISE with SAP offering is a modern cloud ERP that gives enterprises a secure and exclusive cloud infrastructure for automating their business-critical processes and embedding intelligence into workflows.
Private SAP S/4HANA Cloud ERP gives full autonomy and control to organizations to maintain their industry compliance, ERP infrastructure, and security.
Here’s why SAP Private Cloud is the best private Cloud ERP:
- Innovation at your pace, with a balance of system flexibility and control
- Minimized downtime
- Support by SAP’s cloud infrastructure ensures proactive monitoring
- Lower total cost of ownership (TCO)
-
Drawbacks of Public Cloud ERP
Higher costs: More expensive than public cloud due to dedicated hardware, setup, and ongoing maintenance.
Limited scalability: Scaling up infrastructure can take more time and planning versus the elasticity of public cloud.
Maintenance responsibility: You (or your MSP) are responsible for ongoing updates, patches, backups, and security.
Requires expertise: Internal teams (if not using an MSP) need sufficient technical know-how to manage private cloud environments.
Disaster recovery complexity: Unless specifically configured, DR and failover setups can be more complex than public cloud options.
