Businesses that have grown beyond the capabilities of the entry-level accounting tools and spreadsheets they used to get their operations off the ground typically turn to cloud-based ERP systems to increase efficiency. Similarly, businesses stuck on dated versions of on-premises ERP software are also looking to cloud ERP to capitalize on this delivery model's intrinsic benefits. For companies in this position, two software providers often wind up on the short list: Odoo and Microsoft Dynamics 365. Both have a rich history in the ERP market and a comprehensive set of features for businesses across multiple industries. They both provide a single source of data from across the company and enable automation that saves their customers time and money. Yet, there are key differences between the systems that companies should understand as they compare Odoo with Microsoft Dynamics 365, a group of business applications that includes two ERP systems in Microsoft Dynamics 365 Finance and Microsoft Dynamics 365 Business Central. Read on for a detailed head-to-head comparison of system architecture, functionality, customization, integrations, support, and implementation strategy. All of this information will help buyers identify the best solution for them.
Odoo Overview
Odoo was first launched in 2005 by Fabien Pinckaers, a Belgian entrepreneur, with the vision of building an open-source platform that could unify and simplify business management for organizations of all sizes. It started as a basic open-source ERP solution focused on core business processes, but quickly expanded to include a wide range of integrated applications covering every area of business operations. Odoo offers natively integrated applications for accounting, inventory and order management, sales, purchase, CRM, HR, manufacturing, project management, marketing automation, eCommerce, and more. Unlike traditional ERP systems, Odoo is fully modular, allowing companies to start with just a few applications and scale to a complete ERP platform as their needs evolve. Odoo’s success as one of the world’s most widely used open-source business applications has enabled it to build a global community of developers and partners. In 2015, Odoo S.A. (the company behind the software) introduced Odoo Enterprise, a commercial version with additional features and official support, while continuing to maintain Odoo Community as an open-source edition. Today, Odoo has millions of users and over 42,000 paying enterprise customers across the globe, making it one of the fastest-growing ERP providers in the market.
Microsoft Dynamics 365 Overview
Microsoft’s growth in the ’80s and ’90s came primarily from its operating systems, business productivity tools, and eventually its database offerings. It entered the business application market by acquiring two large ERP providers in the early 2000s that served midmarket and enterprise companies: Great Plains and Navision A/S (this name reflected Navision’s merger with Axapta shortly before it was acquired by Microsoft). Both already offered multiple solutions—some added through acquisitions of their own—and Microsoft later rebranded Great Plains’ systems as Microsoft Dynamics GP and Microsoft Dynamics SL (a reference to Solomon Software, which Great Plains added to its portfolio a few months ahead of the Microsoft acquisition). Microsoft renamed Navision A/S products Microsoft Dynamics NAV and Microsoft Dynamics AX. Typical of software at the time, all were on-premises systems, and Microsoft continued to deliver them that way, selling the products primarily through partners. Eventually, the provider began to offer cloud ERP deployments by letting partners host the software. Years later, Microsoft settled on a cloud ERP strategy with two choices: Microsoft Dynamics 365 Finance (formerly Microsoft Dynamics 365 Finance and Operations) and Microsoft Dynamics 365 Business Central (more on that later). Microsoft Dynamics 365 Finance launched commercially in October 2016 and targets the upper end of the midmarket. Microsoft Dynamics 365 Finance is a robust ERP with strong support for finance, and it offers additional modules for supply chain management, sales (CRM), HR, commerce, and more. However, only a few thousand customers are believed to currently be live in the cloud on Dynamics 365 Finance.
How Odoo Compares to Microsoft Dynamics 365 Finance
While both Odoo and Microsoft offer extensive functionality for many departments and roles, there are critical differences that customers will notice. Let’s take a detailed look at how the design and features of each system compare.
System Architecture
The core difference between Odoo and Microsoft Dynamics 365 Finance is how the two vendors developed the products. Odoo was designed from the start as a modular, web-based system that can be deployed on-premises or in the cloud. Customers can choose Odoo Online (managed by Odoo S.A.), Odoo.sh (a platform-as-a-service option), or self-hosted servers. Odoo Online customers are automatically upgraded to the newest release every year, ensuring access to the latest features and security enhancements. Customizations created through Odoo Studio or standard modules typically carry forward with these upgrades.
Microsoft Dynamics 365 Finance’s architecture is based on a rearchitected version of on-premises software that’s not optimized for frequent, automatic upgrades. This leads some customers to hold back on upgrading to the latest version over fears of it breaking integrations and bolt-on applications. This can mean that not all customers are on the same version of the software, even though all are paying for these regular upgrades through their annual subscription fees. Those customers not on the latest version are missing out on the latest features and security enhancements, which could prevent them from realizing the full value of the system and make them more vulnerable to damaging cybersecurity attacks.
Finance
As the name suggests, Dynamics 365 Finance has strong accounting, financial management, and financial reporting capabilities. Like Odoo, it offers real-time financial data and reporting, though in Dynamics reporting may often require using external Microsoft products (such as Power BI) or third-party tools.
Through Microsoft’s licensing agreement with a third party, Dynamics 365 Finance supports subscription billing and advanced revenue recognition that is especially relevant to many software and services companies. Odoo, on the other hand, natively supports subscription billing and revenue recognition through its Accounting module and additional applications.
Reporting and Analytics
A centralized source of companywide data is the central benefit of an ERP system. This enables intuitive, comprehensive reporting to help businesses monitor performance and make the most of their resources. Odoo comes with an extensive set of dashboards and prebuilt reports for different roles and functions. Nontechnical users can easily create new reports to uncover additional insights. Odoo also offers advanced data analysis capabilities through its Pivot Tables, Graph views, and customizable dashboards, which make it easy to drill down into data to uncover business insights. These tools can pull financial, customer, product, and services data directly from the ERP system.
Odoo also offers a unique differentiator with its Filters, Group By, and Favorites (Saved Searches equivalent). Businesses can use these features to quickly find relevant records across their systems—including customer, financial, inventory, supply chain, and other records—with no configurations or coding. Users can save the results for future reference and even include them in dashboards that always display the latest results. Something similar can be achieved in Dynamics 365 Finance, but it requires additional developer resources familiar with C# and SQL-based coding.
While Dynamics 365 Finance offers some prebuilt reports, many customers rely on building reports themselves and integrations with other applications, notably Microsoft Power BI, to deliver data visualizations, dashboards, and financial reports. But note that Power BI is a technical application that requires people familiar with the system to build custom reports.
Configurations and Customizations
An oft-overlooked aspect of selecting an ERP system is finding people who have experience setting up and managing the system. The SaaS ERP model solved many of those issues by eliminating the need for an IT staff responsible for managing the software, servers, and data centers—the SaaS provider handles all of the hosting requirements, patches, and updates. Moreover, Odoo has taken a “clicks not code” approach that empowers nontechnical users to tailor the system to their needs through custom fields, custom reports, and workflows without the need for programming. For more advanced needs, Odoo Studio provides a low-code/no-code environment to build apps and automations. For deeper technical requirements, Odoo is built on Python and PostgreSQL, both of which have a large global community of skilled professionals.
Making customizations to Dynamics 365 Finance often requires more specialized coding capabilities and knowledge. It is based on .NET and SQL frameworks and also leverages the popular C# language. Thanks to its legacy Axapta backbone, users also benefit from knowledge of the older X++ language. The need for greater technical resources to make the system fit your needs can add to the cost of ownership. Additionally, there is concern that developers will need to understand both the old and the new technical aspects of Dynamics 365 Finance, given its convoluted evolution over the last two decades.
Integrations
Not all Dynamics 365 modules are on the same codebase. The CRM module, for instance, was built primarily by Microsoft itself rather than leaning heavily on acquired technology, so it’s on a different codebase than the Dynamics 365 Finance platform. This means it functions as a separate application and has a different user interface. Customers must utilize Microsoft’s Dataverse middleware to pass data and perform workflows between the finance and other Dynamics 365 applications.
With Odoo, the entire suite is built on a single integrated platform, where all applications (CRM, Sales, Inventory, Accounting, Manufacturing, etc.) share the same codebase and database. This simplifies customizations and removes the need for middleware. It also makes the upgrade process smoother because customers don’t need to test those customizations separately every time there’s a new release.
Microsoft Dynamics 365 Business Central Overview
To create Microsoft Dynamics 365 Business Central, the company rearchitected its Navision product for the cloud and designed it for smaller companies than Dynamics 365 Finance. Microsoft released Dynamics 365 Business Central in 2018, meaning it is also newer than its Dynamics counterpart.
Business Central is often priced very competitively, but companies should realize that they will get what they pay for. The system lacks functionality many midmarket businesses need as they outgrow their entry-level accounting system, and support for this functionality requires third-party applications that plug into the ERP. These integrations to other applications can quickly drive up costs, and each represents a potential point of failure. Additionally, companies considering Business Central should know that it’s not necessarily simple to set up, even though it’s less robust than Dynamics 365 Finance.
How Odoo Features Compare to Microsoft Dynamics 365 Business Central
Many of the same caveats that apply when evaluating Odoo and Microsoft Dynamics 365 Finance also apply to Dynamics 365 Business Central. In the sections below, we dig into the details of what separates Odoo and Dynamics 365 Business Central.
System Architecture
As with Dynamics 365 Finance, the on-premises heritage of Business Central impacts the current solution. That means not all customers are necessarily on the same version of this software. Microsoft customers on outdated versions could be missing out on key security enhancements, putting their critical data and processes at greater risk. They also miss out on new features and other system enhancements that could make their operations more efficient. In the meantime, some customers must rely on internal staff or paid consultants to help them upgrade to newer versions.
Odoo, on the other hand, is developed as a modular, web-based ERP platform. Customers can choose Odoo Online (managed cloud), Odoo.sh (platform-as-a-service), or on-premises deployments. Odoo Online users are automatically upgraded to the newest version once per year, ensuring they benefit from the latest features and security enhancements without requiring internal IT resources.
Revenue Recognition
Odoo provides revenue recognition features through its Accounting and Subscription modules, enabling compliance with international standards (including IFRS). Subscriptions and service contracts can be configured to recognize revenue over time, which is particularly important for software and services companies. Business Central has more limited revenue recognition capabilities that often require non-native extensions or integrations.
Billing
Odoo offers flexible billing functionality through its Subscription and Invoicing modules. Businesses can manage recurring billing, milestone-based billing, and usage-based invoicing directly in the system. It supports multiple pricing models, discounting rules, and customer-specific rate cards, making it easier to automate complex invoicing scenarios. By contrast, Business Central’s billing features are more limited and typically require customization or third-party add-ons.
Intercompany Consolidation
Dynamics 365 Business Central often requires either external tools or manual work to handle multisubsidiary and international consolidations, creating another headache for companies structured this way. Localizations for organizations operating in multiple countries each require separate instances on separate databases. Third-party applications designed for Business Central are usually the best way to handle consolidations, but external tools typically mean integrations and another source of expenses and potential problems.
Odoo’s multi-company functionality is built into its unified platform. Each subsidiary can operate with its own chart of accounts, local currency, and tax localization, while transactions are automatically consolidated at the parent company level with proper currency conversion. This allows international, multisubsidiary businesses to manage consolidation and reporting within Odoo itself, without relying on separate databases or external applications.
Reporting and Analytics
Again, Odoo comes with a wider array of reports and analytics that are built into the system than Business Central. Business Central has limited prebuilt reports, and if customers want anything beyond that, they frequently turn to integrations with outside tools including Power BI or Jet Reports. Each of those integrations require setup and maintenance, adding to costs.
Additionally, Odoo’s global search and advanced filter capabilities mean customers can drill down from reports to the individual transaction level and build their own reports and dashboards without any need for coding. That can be more difficult with Microsoft. For example, if a customer has Dynamics 365 Business Central and Dynamics 365 Sales, which are two distinct systems, they may not be able to push and pull data between those two systems without custom development, limiting reporting capabilities.
Configurations and Customizations
While Dynamics 365 Business Central does not require the same level of technical expertise to make system customizations or create custom reports as Dynamics 365 Finance, it still does not match the simplicity of Odoo’s “clicks not code” approach. Odoo allows end users to configure fields, workflows, and reports directly, and Odoo Studio provides a low-code/no-code environment for building new apps and automations.
Odoo is a more complete system out of the box and includes more prebuilt functionality that makes implementation and configurations easier. End users and administrators will find it far easier to adapt Odoo to their unique needs without requiring internal or external technical assistance. This becomes more important as a business grows and its processes evolve.
CRM
The Dynamics 365 Business Central feature set is broader than Dynamics 365 Finance, its counterpart for larger companies, if not quite as functionally rich. Business Central includes a CRM system with contact management features and other tools for sales force automation. The solution also includes project management capabilities.
Odoo offers CRM functionality natively integrated with its ERP platform, including contact management, lead and opportunity tracking, sales pipeline management, marketing automation, and quotation tools. Odoo also includes project management features such as task tracking, timesheets, and project billing. Because CRM, project, and ERP modules all run on the same Odoo database, there is no integration to manage.
For more robust or specialized CRM and marketing capabilities, Dynamics 365 Business Central customers frequently turn to outside modules that can quickly drive up the solution’s total cost of ownership.
HCM
Business Central also includes human capital management functionality in the core system (this was previously offered through a separate HR module).
Odoo provides human resource management through a suite of native HR apps, including recruitment, employee records, payroll, attendance, time-off management, performance management, and expense tracking. These HR modules are fully integrated with the rest of the ERP, enabling organizations to unify HR processes with finance, projects, and other core functions.
Why You Should Choose Odoo Over Microsoft Dynamics
Regardless of which Microsoft Dynamics 365 product a company is considering, there are limitations decision-makers should be aware of when comparing those systems to Odoo. The first is Microsoft’s decision to put two different cloud ERP products on the market.
Microsoft customers run the risk of outgrowing Dynamics 365 Business Central. If that happens, the move to Dynamics 365 Finance would essentially be a new implementation, resulting in disruption and steep costs. The inverse is also true—downgrading from Dynamics 365 Finance to Business Central is akin to replacing your system.
Odoo, by contrast, is a single modular platform used by companies of all sizes—from startups with just a few employees to large enterprises with thousands of users. Businesses can start small by adopting only the apps they need, and then add functionality as requirements grow. If the business later decides to scale down, it can simply deactivate modules without needing to reimplement the system.
Approach to Implementation
Odoo provides a straightforward implementation approach thanks to its modular design and best practices developed by its global community and partner ecosystem. Industry-specific modules, prebuilt workflows, and dashboards allow organizations to get up and running quickly. Customers can choose between Odoo’s own cloud services (Odoo Online, Odoo.sh) or work with one of the many certified partners worldwide.
Microsoft does not offer an implementation methodology comparable to this. Most implementations are partner-led, making it more difficult to share learnings across the ecosystem and follow consistent best practices. Moreover, because both Microsoft products are based on a combination of older and newer technologies, implementations are usually more complex and demand a wider range of skill sets.
Customer Support
Microsoft relies on its partner network for frontline support that is limited to any one partner’s business hours. Customers have little contact with Microsoft directly, and partners are mostly interested in ongoing consulting engagements and billable hours, so support often becomes secondary.
Odoo, on the other hand, offers vendor-provided support along with a global partner network. Customers using Odoo Online receive support directly from Odoo S.A., ensuring access to professionals who know the system inside and out. Odoo’s large community also contributes extensive documentation, forums, and resources that make problem-solving easier and faster.
Additionally, Microsoft must split its support resources across multiple ERP products and business lines, meaning it cannot offer customers the same level of focus as a provider like Odoo that dedicates all its resources to one unified system.
Research and Development
Both Odoo and Microsoft continue to invest in their ERP product lines, adding functionality and industry-specific capabilities. However, Odoo is solely focused on continuously expanding its ERP ecosystem, releasing a major new version every year with hundreds of new features and usability improvements. Microsoft’s resources, in contrast, are divided between multiple ERP products with distinct architectures, as well as its many other lines of business.
Odoo Is Right for Growing Businesses
Many companies are making the case for a new ERP system and trying to determine if they want to migrate from QuickBooks to Odoo, from Microsoft’s on-premise systems such as Microsoft Dynamics GP to Odoo, or to one of Microsoft’s cloud ERP offerings. As they weigh the risks and benefits of different systems, they need to account for the product’s history, current level of adoption, base functionality, costs, and difficulty of customization and maintenance. Moreover, they should ask if the system has the scalability to continue supporting the business as it grows.
After evaluating each of those areas, many businesses will realize that Odoo is the clear winner.
