What is cloud ERP? Guide to a cloud ERP system
June 18, 2026
Cloud has been a buzzword for about a decade now. Even before the pandemic, businesses worldwide recognized the potential of cloud software. The pandemic had proved them right about betting on the online format, with enterprise resource planning (ERP) software making a lion’s share of cloud solutions. Accessing operational and financial business functions from anywhere via the internet? Processing orders for inventory or the supply chain from a smartphone in a few clicks – yes, please. No wonder the relic, on-premise business solutions, are losing relevance.
The numbers speak for themselves: today, cloud ERP is becoming a default choice. Industry statistics show that about 70% of current ERP solutions are already cloud-based, while almost 80% of those about to implement an ERP are going to be cloud-based.
If a new cloud ERP solution is what you are currently considering, dive deeper into what that is, what use you can make of it, and what you should be aware of when choosing the path to the cloud. Follow the guide below to grasp the possible nuances, benefits, and challenges a cloud solution has to offer before you purchase it.
What is cloud ERP?
ERP, or enterprise resource planning, is a critical business software. It embraces core operational processes into a unified system. Enterprise processes in HR, finance, sales, inventory, project management, and more – all run in one common database. Data flows in real time between departments.
In a cloud ERP, this concept is realized thanks to the internet. Businesses no longer need to manage on-premise servers. Instead, they subscribe to a cloud-based platform. This way, the technical infrastructure remains on a cloud vendor’s side: the servers, updates, and what is more, security. What a business does is access the system online, from a web (browser) app or a mobile app, from any location.
What does an ERP mean in practical terms? It means a huge shift from managing one's own costly infrastructure to using business software as a service. The thing is often defined as SaaS ERP. A modern ERP is a convenient and reliable place to run transactions and enforce business rules, generate reports and make decisions – across teams and departments, all in one place, all in real time.
How does a cloud ERP system work?
In layman’s terms, it works like this. Vendors or third-party providers like Microsoft Azure or Amazon Web Services (AWS) manage remote servers. That’s where the cloud ERP systems run – on these remote servers. For security reasons, encrypted internet connections are used to move the data. Role-based permissions control access to the systems.
Let’s dig a little deeper.
Architecture under the hood
Cloud ERP relies on a distributed cloud infrastructure, meaning the system spreads computing (calculations), storage (company’s data – orders, customers, inventory), and networking (connections that enable users and systems to “talk” to the remote servers) across many cloud servers. These servers (secure data centers) are managed by cloud ERP vendors.
A click on a button in an ERP user interface sends a request over the internet to these data centers. There, the app processes it and returns the result. Such scalable storage and computing can be expanded on demand.
Single data as a pillar
The use of a central cloud database enables instant updates across modules, as sales, HR, inventory, finance, and supply chain are tied together. Making changes in one module makes other modules react to this change and update their own data accordingly.
Teams and departments can work smoothly, without silos, using the same data rather than separate spreadsheets.
User interaction with the system
Users access the system through a mobile app or a web browser. Often – and it’s a best practice – the access is tailored to specific roles (management, sales, warehouse, etc.).
Basically, user interaction is minimized to daily operational workflows as everything else – server management, patch installation, or backups – is handled externally by the vendor. As a rule, security fixes and automated updates are part of that external hosting.
Automation and integrations
Automation is a huge advantage of a cloud ERP. The system automates key business workflows (order-to-cash, inventory-to-supply-chain operations, and more). Posting logic, notifications, and approval rules are built in (and might be customized if specific business processes require that).
Useful third-party integrations can amplify a cloud ERP’s potential even further. E-commerce, payment gateways, and many other external systems can be added through APIs or connectors to let data flow, skipping manual cycles of importing and exporting it.
Core modules of a cloud ERP system
At its core, an ERP system is a set of integrated modules. Each of them is responsible for a certain business functionality. The same basic logic applies to on-premise ERP solutions, but the key difference is the deployment method, management, and customization possibilities overall.
Before choosing an ERP solution, it’s worth mentioning that certain modules might be built-in as “out-of-the-box” options – available straight away, while other vendors may ship them differently, as additional elements.
Either way, a traditional suite of modules across ERP solutions includes:
Financial management. An absolutely basic feature of an ERP. Deals with general ledger, accounts payable and accounts receivable, budgeting and asset management, and reporting, with full audit trails in place.
Supply chain management deals with purchasing, receiving, and inventory tracking. It also manages logistics – how products are delivered from the supplier to customers.
Inventory and warehouse management. These deal with visibility into stock in real time, multilocation, and reorders that are triggered automatically.
Human resources (HR) and payroll. The module deals with employee records, time tracking, payroll, and more. In some ERPs, the HR module comes as an external part.
Sales and CRM. Customer data, order management, pricing rules and more. Like the HR module, CRM is sometimes integrated additionally.
Project management. Allocating resources, budgeting, analyzing profitability and more – all done here.
Reporting and analytics. Tools for business analytics and dashboards that help extract insightful information from data. These are often part of standard ERP suites, along with the project management module.
Manufacturing. Manages production scheduling, bills of materials (BOM), quality control, etc. Standard in some ERPs, while optional and niche in others.
The connection between modules is the real value of any ERP. Entering data in one module pushes it to flow across other modules – without duplicating entries and human errors, providing a complete operational overview instead.
Cloud ERP vs on-premise ERP
The opposition of on-premise VS. cloud versions often boils down to the hosting method. In reality, they differ in costs and flexibility, as well as technical responsibility and risks they pose from a long-term perspective.
ERP cost
☑️ Choosing on-premise implies considerable upfront costs: licenses, hardware, IT teams, and upgrades.
✅ Cloud ERPs, on the other hand, offer more predictable expenses as they use a subscription model with hosting, support, and updates already covered. The total cost of ownership for cloud solutions can often be considerably lower over several years.
Deployment peculiarities
☑️ To operate, on-premise ERPs use local servers owned by the business itself. IT teams are responsible for hardware, disaster recovery, and network security.
✅ For a cloud ERP, a business needs the internet to work. The rest is handled by the vendor.
Implementation duration
☑️ It may take up to a year to implement an on-premise solution.
✅ It’s faster for cloud ERPs. Since infrastructure is on the vendor’s side, it usually takes from several weeks to a few months to implement a cloud ERP.
Maintenance and updates
☑️ Upgrading a local ERP means running an entire project with testing new features and running into downtime.
✅ For cloud solutions, vendors apply updates automatically. Software remains current and secure. Business operations do not disrupt.
Security
☑️ Full responsibility for physical hardware, backups, and patches falls on the organization.
✅ Reliable cloud vendors spend billions on cybersecurity. Entire teams are responsible for that: testing, sticking to ISO 27001 standards, reacting to any issues with instant patches.
Accessibility
☑️ To work in an on-prem application, users need access to a physical network or VPN for remote work.
✅ An internet connection is all it takes for an ERP to run. On any device, from any location.
Considering the risk versus benefit, cloud ERP is the better option for most organizations today. The only question is getting to the cloud in a proper way.
Key benefits of cloud ERP
Lower total cost of ownership
Moving to the cloud means cutting costs on IT infrastructure and physical servers. Budgeting becomes more predictable with subscriptions, and vendor-managed maintenance makes cloud ERPs cost-effective in the long run. The costs businesses save this way can be redirected to product development and sales instead.
Swift implementation
Well-planned and properly realized, cloud ERP implementations may happen several times faster than on-premise alternatives. Stairway to Cloud, our phased approach to cloud adoption, helps move with minimal process disruption. To make the migration process as predictable as possible, we recommend starting from Discovery X-ray. The package helps identify customizations in the current ERP software to decide which should be moved to the cloud as crucial ones, which should be replaced with extensions, and which should be left behind.
Staying updated
Cloud ERPs receive updates automatically, as this process remains on the vendors’ side. Security patches are also automated. Businesses do not run the risk of using outdated software.
Better scalability
A whole new level of scaling possibilities for businesses. It’s enough to change configurations, not run an entire hardware project, to enable new modules, add users, or expand into new geographies. A cool advantage for growing businesses to let the technology keep up with their ambitions.
Global remote access
Cloud ERP can be used from anywhere, be it home, office, or on the road. From any device. If teams are scattered across multiple spots, or a physical office becomes unavailable for any reason, remote access becomes a real structural advantage.
Enterprise-level security
Individual businesses can barely beat the cloud vendors’ investments in security and compliance certifications. Security patches apply instantly, as soon as they are released.
Easy integration with third-party apps
Modern cloud ERP systems are all about connection. Through open APIs, they link with analytical and e-commerce tools, logistic partners, CRM systems, and more. Tools like Jira Connector for Business Central extend the ERP capabilities: businesses do not need to manually copy data between the task management tools (Atlassian Jira and Tempo) and Business Central.
Proper maintenance once in the cloud
The quality of support a vendor provides after implementation defines how long a customer stays. This traditionally implies they react faster to any issues and monitor the solution proactively. Professional, high-quality Business Central cloud maintenance keeps the solution up and running – and evolving – long after it’s implemented.
Challenges and limitations of cloud ERP
There are no perfect technologies. Sometimes it needs a middle ground to work. That’s why there are several related challenges organizations considering the move to a cloud ERP should be aware of.
Dependency on the internet connection
The internet connection must be really reliable for an ERP to work properly. Connection goes down = operations stop, making downtime very expensive.
☑️ TIP: backup plans and offline capabilities for certain features and processes.Changes are hard to accept
Staff might find it challenging to get used to a new cloud solution.
☑️ TIP: structured user training to later use the cloud advantages in full.Data migration might be a challenge
Transferring legacy data to the cloud is one of the largest obstacles to any cloud migration. Moved in the wrong way, with inconsistencies, missing records or duplicates, poor data weakens the ERP from the very start.
☑️ TIP: professional data migration services help avoid such issues by moving exactly what is needed in the cloud instead of dragging extra.You cannot NOT pay for a subscription
Subscription costs do not stop.
☑️ TIP: modeling total cost of ownership for 5-7 years to come before deciding to move to the cloud, considering all the pros and cons.Little room for customization
Cloud ERPs prefer standard features rather than customizations. Businesses might need to come up with certain workarounds or deploy to private clouds for highly unique business processes.
☑️ TIP: using low-code apps/extensions (Power Apps, for instance) instead of changing the core code.Dependency on the vendor
Going cloud means making a long-term commitment to a cloud vendor.
☑️ TIP: checking how stable the vendor’s finances are and what support models they cover is critical before sealing the deal.
Types of cloud ERP deployment models
Traditionally, three deployment models are deemed the most popular for cloud ERPs.
Public cloud (SaaS, Software as a Service)
This model is the most common: vendor's shared infrastructure hosts the software and delivers it via subscription.
Benefits: less expensive upfront (minimal initial payment); offers fast implementation, and regular automated updates.
Best fit: SaaS works really well with small and mid-sized businesses.
Private cloud
A more expensive alternative, meaning an organization uses a dedicated infrastructure to run its ERP. Usually, a third-party cloud provider hosts it.
Benefits: data is better controlled and isolated.
Best fit: industries with strict regulations, e.g., financial services or healthcare.
Hybrid cloud
Literally, a blend: cloud + on-premise, or even public + private cloud. Usually more challenging to manage.
Benefits: could be an option when a business uses a cloud ERP version for standard features while keeping an on-prem system for tailored, niche operations.
Best fit: phased, step-by-step cloud migrations when switching everything at once is impossible.
Who should use cloud ERP?
Even though cloud ERP is often a good fit for a wide range of organizations, it does not work for every scenario.
Who can benefit practically straight away:
Small and medium-sized enterprises that grow fast and need to scale up but keep investments in IT infrastructure quite low.
Teams across multiple locations wanting to access a unified system from any spot, any time.
Businesses expanding to new markets where on-prem apps would be challenging or impossible.
Those replacing on-prem ERPs nearing the end of support or spreadsheets.
Who might need a customized advice:
Companies located in places with unstable internet should address this issue before completing a cloud migration.
Enterprises with deeply customized local ERPs may need to consider a phased transition to the cloud.
Defense, financial services, some healthcare segments, and any other sectors that are strictly regulated may consider a hybrid or private cloud model.
With BC development services and quality assurance in place, standard ERP functionality might be smoothly connected with specific operational processes.
How to choose the right cloud ERP system
The right choice here depends greatly on how structured an approach to this matter is. A business or an organization risk preferring a costly false start over a game-changing implementation, unless they think of choosing cloud software as a vital step as well.
1
The most critical: set requirements before choosing a vendor. This is a must. Put current processes in black and white. Single out the must-haves for the cloud. Doing this beforehand means avoiding expensive surprises along the way.
2
Calculate how much the entire project will cost you, not simply subscription payments. A combo of a cheap subscription and a complex implementation can eventually turn out to be a very expensive option.
3
Pay attention to how stable the vendor is and the roadmap they offer. Check the track record and experience in the industry. Check how often the updates are going to be delivered and what support modes they have.
4
Make the list of the most important apps you need to integrate with your ERP. Make sure that the vendor supports integrations with the tools you already use (via marketplace add-ons or built-in).
5
Test before you make a project commitment. Use a sandbox environment first. It’s a chance to check if your data really fits in. A scripted demo might be not enough.
6
Plan the implementation itself, in details. Keep in mind the budget for data migration, training, and maintenance after you are finally in the cloud. Planning is critical as underestimating implementations is one of the main reasons such endeavors fail.
Future trends in cloud ERP
AI turns ERP into a system of intelligence.
Automation based on AI deals with data entry. It also flags unusual operations and anomalies in transactions. What’s more, AI now works with natural-language interfaces, enabling users to communicate with the system as if they simply have a conversation.
Going modular instead of monolithic.
More and more organizations prefer composable systems, assembling the most suitable modules connected by APIs. ERP solutions are becoming more flexible, but at the same time, they require greater attention to how they are integrated.
Vertical (industry-specific) solutions are gaining popularity.
Vertical ERP software addresses specific sectors’ needs better, makes implementation shorter, and customization costs lower. Niche, specialized businesses get better access to enterprise-level functionality.
ESG (environmental, social, governance) reporting.
Regulatory pressure on businesses rises. More environmental, governance, and social data needs to be integrated into ERP processes. In addition to financial data, such flows track carbon emissions, social metrics, and much more.
Bottom line
Those businesses that value modern, flexible, and cost-effective management for their operations choose cloud ERP. And it’s more than a technical change. It’s a change in long-term strategic thinking: placing bets on better scalability, security, and innovation – things that on-prem and legacy apps can barely offer. Overall, the meaning of an ERP itself is changing.
It does make sense. Cloud ERP is cheaper to operate in the long run. It also means automated updates to stay current all the time. It can be accessed from anywhere and at any time. Security is provided on the enterprise level, and a huge ecosystem of integrations and AI-driven features is available on top. Over time, using cloud ERP brings even more advantages: technical obstacles fade, new capabilities are easier to adopt, and internal teams experience less day-to-day workload.
The challenges of cloud adoption are real, but for sure manageable. With a good implementation partner and the right, suitable approach to cloud migration, this transition becomes a well-reasoned investment. A planned cloud migration, starting from an assessment of the current software, makes the real difference.
