Odoo or Dynamics 365 Business Central: the UK comparison

If you are weighing Odoo vs Business Central, you are usually choosing between two very different philosophies. Odoo is a modular suite built around applications you switch on as you need them. Microsoft Dynamics 365 Business Central is a structured, finance-led platform that sits naturally inside the Microsoft ecosystem and is delivered through a network of partners. Neither is better in the abstract. The right answer depends on your processes, your people and the integrator who will deliver the project.

This page sets the two side by side on the same headings, then gives a verdict by company profile. It is written for finance directors, managing directors and IT leads of UK small and mid-sized businesses. If you are still at the stage of defining the project, our guide on how to choose an ERP is a good starting point. The vendor pages for Odoo and Business Central give more detail on each product.

Odoo or Dynamics: the short answer

Choose Odoo when you want breadth across many business functions in one suite, flexible configuration, a lower entry price per user and the option of an open-source community edition. Choose Business Central when finance is the heart of the project, when your team already lives in Microsoft tools, and when you value a more standardised product with a clear partner channel.

In practice, many shortlists contain both, and the deciding factor is rarely the software alone. It is how well a given integrator understands your sector and how realistically the scope is defined. That is why the comparison below also covers delivery and support, not only features.

Odoo vs Business Central at a glance

Scope and functions

What Odoo covers

Odoo is organised as applications: accounting, sales, purchasing, inventory, manufacturing, projects, e-commerce and more. Odoo states that it offers 50 main applications, and that its community has contributed more than 50,000 additional ones. The advantage is that a company can start with a few applications and add others later. The caution is that a wide catalogue calls for discipline: without a clear scope, a project can grow in every direction.

What Business Central covers

Business Central is built for small and mid-sized organisations that want finance, sales, purchasing, inventory, projects and service management in one system. Its structure is more guided than Odoo's, which many finance teams value because it makes processes easier to standardise and audit. Where you need something outside the standard scope, extensions are normally developed by a partner.

Where the difference shows

Industry fit matters more than any feature list. A discrete manufacturer, a wholesaler, a service firm and an online retailer will each stress the two systems differently. Our pages on manufacturing ERP, wholesale and distribution ERP and professional services ERP explain what to test for each sector before you shortlist.

Licensing and pricing

Both vendors charge per user per month, but the structures differ, and the published prices are not quoted in pounds sterling, so treat the figures below as indicators rather than a UK quote.

Odoo plans

Odoo publishes a free One App Free plan, limited to one application plus its dependencies, hosted on Odoo Online, with unlimited users. The Standard plan is listed at 24,90 EUR per user per month (reduced from 31,10 EUR for twelve months for the users ordered at the start), with all applications on Odoo Online. The Custom plan is listed at 44,90 EUR per user per month (reduced from 56,90 EUR for twelve months), with a choice of Odoo Online, Odoo.sh or on-site hosting; Odoo.sh costs are not included. Odoo also lists a light user at 7,90 EUR per month, arranged through an Odoo adviser.

Two details are worth noting. First, Custom adds Odoo Studio, agentic AI, multi-company and external API access, and installing Studio or adding companies moves a free database to Custom. Second, paying users are those with backend access: portal users such as customers and suppliers are not counted as paying users.

Business Central plans

On Microsoft's US page, Essentials is listed at 80 USD per user per month and Premium at 110 USD per user per month, both billed annually. Team Members is listed at 8 USD per user per month, also billed annually. Microsoft states that displayed prices may differ from the actual list price depending on currency, country and regional variant, and that the final price appears at checkout. For a UK figure, you need a quote in pounds sterling.

What the licence does not include

Subscription fees are only one line of the budget. Implementation, data migration, configuration, training, integrations, hosting where applicable and ongoing support are paid to the integrator and depend on scope. Our guide to ERP cost breaks down the budget lines to expect, and it applies to both products.

Open source, licences and openness

Odoo is available in two editions. According to its documentation, Odoo 19 Community is released under the LGPLv3 licence, while Odoo 19 Enterprise is released under the Odoo Enterprise Edition licence v1.0 and may be used only with a valid Enterprise subscription covering the right number of users. This gives UK firms a genuine open-source route, with the trade-off that some features and support sit in the paid edition. Our guide to open-source ERP explains what that means in practice.

Business Central is proprietary software. You do not hold the code, but you benefit from a vendor-managed product, a defined release cycle and an extension model that partners know well.

Hosting and deployment

Odoo is deployed on Odoo Online (software as a service), or on Odoo.sh or on your own premises under the Custom plan. This range suits firms with specific hosting or data requirements.

Business Central is mainly consumed as a cloud service from Microsoft. If your organisation is comfortable with a vendor-hosted model, this reduces the infrastructure you must run yourself. If you need to understand the trade-offs more broadly, read our comparison of cloud and on-premise ERP.

UK localisation, VAT and e-invoicing

Localisation is where a UK buyer should be most careful. Microsoft provides the Business Central localisation directly in 21 countries, including the United Kingdom, Austria, Belgium, Germany, France, Italy, Mexico, the Netherlands, Spain and Switzerland. For other countries, localisation comes through partner-built apps on Microsoft's marketplace. Being in the first group is a reassurance for UK buyers.

Odoo relies on its localisation packages and on the work of your integrator to align charts of accounts, VAT handling and reporting with local practice. Either way, do not rely on a feature list: ask the integrator to demonstrate your real VAT scenarios, your banking formats and your reporting needs on your own data. Digital invoicing is changing quickly, and our guide to ERP and e-invoicing sets out the questions to raise.

Customisation and integration

Odoo is known for flexibility. Studio-style tools, a large module ecosystem and an open code base let integrators adapt the system closely to a company. That is an asset, provided the customisation is controlled: every bespoke change adds to future upgrade work.

Business Central encourages extending rather than altering the core. This makes upgrades more predictable and keeps the product closer to its standard, which finance teams often prefer. It also means that unusual requirements need a capable partner.

On integration, Business Central fits naturally with the wider Microsoft environment. Odoo can connect to Microsoft services and to third-party tools, but the integration is a piece of work to scope and price.

Integrators, partners and support

Neither vendor implements projects itself in the way a single supplier would. Odoo reports more than 21,000 partners, more than 8,000 employees and 17 offices, and claims more than 28 million users worldwide, ranging from a single user to more than 300,000 for its largest customers. Business Central is likewise delivered through a partner channel.

The consequence is simple: the integrator shapes the outcome as much as the software. Compare their sector references, their method, how they handle data migration and what support they offer after go-live. Our guide on choosing an ERP integrator lists the questions to ask. We do not implement ERP ourselves and we are not affiliated with any vendor: we introduce you to an integrator that fits your project, and the integrator carries out the work. Our how it works page explains the process.

Verdict by company profile

If you are a small business

For a very small firm, the entry route matters. Odoo's free plan lets you test a single application, while Business Central is priced from the start as a full business system. Our guide on ERP for small business and our ranking of the best ERP for small business cover this stage in more depth.

If you are a growing mid-sized company

Here the decision rests on process complexity, reporting needs and the number of entities. Both products can serve a multi-company group, although Odoo requires the Custom plan for multi-company. If you are also considering enterprise-grade alternatives, see NetSuite vs Business Central and SAP Business One vs Business Central.

How to decide without regret

1. Write down your processes first. A short requirements document prevents both systems from being judged on their demonstrations rather than on your needs. Our ERP requirements template helps.
2. Shortlist integrators, not only products. Ask each to show a comparable project.
3. Demand a scripted demonstration. Use your own data and your hardest scenarios, including VAT and stock.
4. Request a full quote in pounds sterling. Include licences, implementation, training and support.
5. Plan the migration and the risks. Many failures come from data and change management, as our guide to ERP project mistakes shows.

You may also want to compare Odoo with other options, for example Odoo vs Sage or Odoo vs SAP Business One.
