Business Central Cloud vs On-Premises: Differences, Costs in Australia and Fit

Business Central Cloud, also called Business Central Online or SaaS, is hosted on Microsoft Azure as a subscription service managed by Microsoft, while Business Central On-Premises is hosted on local servers or private infrastructure managed by your organisation or IT provider. Both deployments share core ERP capabilities across finance, inventory, purchasing and supply chain management, but differ in hosting, updates, costs, security responsibilities, customisation and access to Microsoft’s cloud and AI capabilities.

For Australian businesses, the right deployment depends on operational requirements, existing infrastructure, IT resources, customisation needs, total cost of ownership and future technology plans. Existing Business Central On-Premises users must also consider whether to maintain their current environment or assess a move to Cloud.

This guide compares the key differences, total costs in Australia and which deployment fits different business requirements. For existing On-Premises users, it also explains when to consider staying with their current system or migrating to the cloud.

Business Central Cloud vs On-Premises: What’s the Difference?

The fundamental difference between Microsoft Dynamics 365 Business Central Cloud and On-Premises is how the system is hosted, managed, and maintained, rather than its core functionality. Business Central Cloud runs on Microsoft-managed Azure infrastructure, while Business Central On-Premises runs on infrastructure managed by your organisation or its IT provider. Both support core ERP operations, but differ in updates, accessibility, security responsibilities, customisation, integrations and access to cloud-based AI capabilities.

Business Central Cloud runs on Microsoft Azure, while On-Premises runs on infrastructure managed by your organisation.

Business Central Cloud vs On-Premises at a Glance

Hosting, Access and Updates

Business Central Cloud is hosted on Microsoft Azure, with Microsoft managing the infrastructure, service availability and updates. On-Premises gives organisations greater control over their hosting environment and upgrade schedules, but requires more internal or outsourced IT resources.

Features, AI and Microsoft Platform Integration

Business Central Cloud and On-Premises share the same core ERP capabilities, but Microsoft takes a cloud-first approach; new AI features, Copilot and platform integrations are built for Cloud first, with On-Premises receiving limited or no equivalent access.

Independent ERP analysts note that Business Central’s Copilot capabilities are designed around everyday finance and operations tasks, such as vendor invoice processing, sales order creation, and cash flow exceptions, rather than as a separate analytics layer, making AI features more accessible for lean back-office teams (ERP Today, 2026).

Security, Data and IT Management

The key security difference between Business Central Cloud and On-Premises is who manages and maintains the underlying environment. Microsoft handles cloud infrastructure and platform security, while On-Premises places greater responsibility on the organisation or its IT provider.

Customisation and System Integrations

Both deployments support extensions and integrations, but their technical flexibility differs. Cloud relies on supported extensions, APIs and connectors without direct access to Microsoft’s managed production SQL database. On-premises provides greater database and infrastructure control.

For existing On-Premises users, database-level customisations, legacy code and integrations should be assessed before moving to Cloud. Some may need to be redesigned, replaced or migrated to supported extensions and APIs.

For example, we’re currently helping a business automate supplier invoice processing by integrating an AI-powered OCR solution with Business Central. On Cloud, the integration connects directly via API with no middleware. On-premises, it would require additional infrastructure to expose the same endpoints externally, possible, but meaningfully more complex to build and maintain.

These differences also affect long-term cost. Beyond licensing, businesses need to factor in infrastructure, maintenance, upgrades and integration support when comparing total cost of ownership.

How Much Does Business Central Cloud vs On-Premises Cost in Australia?

Business Central Cloud typically follows an operating expense (OpEx) model with recurring per-user subscriptions and no server infrastructure costs, while Business Central On-Premises involves upfront capital expenditure (CapEx) for licensing and infrastructure, alongside ongoing maintenance costs. Australian businesses should compare total cost of ownership (TCO) over three to five years, including implementation, integrations, customisation and ongoing support.

Business Central Cloud Costs

Business Central Cloud uses per-user subscription licensing. Essentials covers core ERP functions, while Premium adds manufacturing and service management capabilities. Team Members licences provide limited access.

Microsoft’s published Australian list prices are:

Prices are based on annual billing, exclude GST and are subject to change. Confirm current pricing with Microsoft before purchasing.

Beyond subscription fees, businesses should budget for:

• Implementation, data migration and training.
• AppSource extensions and subscriptions.
• Partner-developed customisations.
• Third-party integrations and maintenance.
• Ongoing support and optimisation.

Microsoft-managed hosting and platform updates are included in the Cloud subscription. Built-in Business Central Copilot is currently included with eligible Online licences, subject to feature availability and usage conditions.

Business Central On-Premises Costs

Business Central On-Premises licensing varies by Microsoft agreement, including perpetual licences, subscriptions or existing entitlements. Businesses are also responsible for managing their hosting infrastructure, either internally or through an IT provider.

Typical costs include:

• Server hosting, hardware and storage.
• SQL Server licensing where applicable.
• Security, backups and disaster recovery.
• Internal or outsourced IT administration.
• Version upgrades and compatibility testing.
• Customisation, integrations and partner support.

On-premises can involve greater upfront and ongoing infrastructure expenditure. Existing customers may benefit from investments already made, but should also consider hardware replacement, technical debt and future upgrade requirements.

Business Central Cloud vs On-Premises: Total Cost of Ownership

A three-to-five-year TCO assessment should consider licensing, infrastructure, user growth, support and upgrades. Cloud may reduce IT costs, while On-Premises can remain viable for businesses with existing investments. A Microsoft-commissioned Forrester study (2026) projected over 200% ROI and a six-month payback for a modelled Business Central Cloud deployment, although actual results vary.

Cost is only one part of the decision. The next consideration is which deployment best fits your business operations, IT capabilities and long-term technology plans.

Which Business Central Deployment Fits Your Business?

Business Central Cloud suits businesses looking to reduce IT maintenance, enable flexible access and adopt Microsoft’s latest cloud and AI features. On-premises may be a better fit for businesses requiring greater infrastructure control, relying on legacy systems or operating with limited internet connectivity. The right choice depends on your operational needs, existing systems, IT resources and long-term technology plans.

When Business Central Cloud May Fit

Business Central Cloud suits Australian businesses that want to reduce infrastructure management, access managed service updates, and use Microsoft’s built-in AI and cloud capabilities.

Cloud may be a better fit if your business:

• Wants faster deployment without setting up servers.
• Needs remote access across multiple locations.
• Prefers Microsoft-managed hosting, backups and disaster recovery.
• Needs built-in Business Central Copilot capabilities.
• Prefers subscription-based software licensing.
• Uses SaaS-compatible extensions and integrations.
• Relies on the native Shopify connector or Teams integration.

The same Forrester TEI study projected that finance teams using Business Central Cloud could reduce monthly close time by up to 30% and AP, AR and billing activities by up to 50%, outcomes attributed to workflow standardisation and unified data rather than AI alone (Forrester Consulting, 2026).

The right deployment depends on your infrastructure, IT resources, and technical requirements

When Business Central On-Premises May Still Fit

Business Central On-Premises is the right fit when infrastructure control, legacy database dependencies, or migration risk currently outweigh the benefits of moving to Cloud.

• On-Premises may be a better fit if your business:
• Requires direct control over hosting infrastructure.
• Relies on legacy code or SQL-based integrations.
• Has critical systems not yet SaaS-compatible.
• Operates in locations with unreliable internet.
• Needs greater control over upgrade schedules.
• Has significant existing infrastructure investments.
• Faces high migration costs or operational risks.
• Must meet data sovereignty requirements for locally controlled hosting.

Remaining On-Premises can be a reasonable decision when these requirements outweigh the potential benefits of Cloud. However, businesses should regularly reassess maintenance costs, software support, security responsibilities and future technology needs.

For new Business Central implementations without specialised technical constraints, Cloud is generally a practical starting point. On-premises remains an option when specific business requirements justify greater infrastructure management and technical control.

For existing Business Central On-Premises users, the decision goes beyond choosing a deployment model. The next question is whether maintaining the current environment remains viable or migrating to Cloud would deliver sufficient long-term business value.

Should Existing Business Central On-Premises Users Move to Cloud?

Existing Business Central On-Premises users should consider moving to Cloud when infrastructure costs rise, major upgrades are due, or their current environment limits business capabilities. However, migration is not always necessary. The decision depends on your Business Central or Dynamics NAV version, customisations, integrations, costs and migration readiness.

When to Consider Moving to Business Central Cloud

Migration to Business Central Cloud is worth assessing when maintaining your existing On-premises environment becomes more costly or limits your business capabilities.

Common triggers include:

• Servers are approaching replacement.
• Your current Business Central or NAV version is nearing a support milestone; Dynamics NAV extended support ends January 2028 (Microsoft, 2026).
• IT maintenance and upgrade costs are increasing.
• Teams need better multi-location access.
• Built-in Copilot or Online-only integrations are required.
• Legacy infrastructure limits business growth.

In our experience, a hardware refresh or major upgrade is a practical opportunity to compare the cost of maintaining On-Premises with migrating to Cloud. These triggers do not automatically justify migration, but they indicate when a formal assessment may be worthwhile.

Migrating Business Central On-Premises to Cloud typically involves five stages: assess, prepare, migrate, test and go live.

What to Assess Before Migrating

Business Central Cloud migration readiness depends on your current version, customisations, integrations, data and business processes. Before migrating, assess five areas that influence technical feasibility, costs and business continuity.

In our experience, the customisation and integration assessment almost always surfaces more complexity than initial estimates suggest; legacy code scope and undocumented SQL connections are the most consistent sources of budget and timeline overrun in migration projects.

1. Current version and support: Check your Business Central or NAV version, support lifecycle and supported migration path. Older versions may require intermediate upgrades.
2. Customisations: Identify custom code, extensions and database dependencies. Determine what can be migrated, replaced, rebuilt or retired.
3. Integrations: Check whether existing applications and integrations work with Cloud. Direct SQL connections may need replacing with supported APIs.
4. Data and history: Assess data quality and historical records to determine what to migrate or archive.
5. Critical workflows: Confirm that Cloud supports essential finance, inventory, manufacturing, reporting and approval processes.

How Does a Business Central On-Premises to Cloud Migration Work?

Migrating Business Central On-Premises to Cloud typically involves five stages: assessment, preparation, migration, testing and cutover. The process varies depending on your current version, customisations, integrations and data requirements.

1. Assess the existing environment: Review your Business Central or NAV version, infrastructure, customisations, integrations and data to determine the supported migration path and project scope.
2. Prepare the Cloud environment: Configure the target environment, resolve incompatible customisations, prepare extensions and integrations, and clean or map data for migration.
3. Migrate data and applications: Transfer supported data using the appropriate migration approach. Deploy compatible extensions and configure the required integrations and business settings.
4. Test and validate: Conduct user acceptance testing (UAT) using real business scenarios. Verify financial balances, data accuracy, reports, integrations, user permissions and critical workflows before sign-off.
5. Cut over and go live: Complete final data synchronisation or migration, transition users to Cloud and monitor operations. Provide training, resolve post-migration issues and establish ongoing support arrangements.

Older NAV or Business Central versions may require intermediate upgrades, data conversion or additional remediation. Not every environment can migrate directly to the latest Cloud version.

Migration should proceed when the expected operational benefits justify the costs, technical changes and business disruption. Where critical customisations or integrations are not yet Cloud-compatible, maintaining On-Premises while preparing a phased migration roadmap may be the more practical approach.

The questions below address the most common points businesses raise before making this decision.
