Odoo or Exact: which ERP fits your SME?

Why is choosing an ERP a long-term decision? 

Choosing an ERP is one of the bigger decisions a growing business makes. It ties together invoicing, inventory, sales, and finance into one backbone. Once it is in place, the way the company operates is shaped around it. That makes the choice worth the time. Do the research, prepare thoroughly, and talk to people who have implemented these systems before. 

The ERP software market is crowded. Some systems target large multinationals. Others are built for SMEs. Odoo and Exact both sit in the SME segment, which is why they end up on the same shortlist. They are not interchangeable, though. Knowing where each one is strongest is what turns a shortlist into a decision. 

Before comparing the two, it helps to be clear on what matters. Which data flows are you trying to manage? Which functionality do you need today, and which will you need in two years? How quickly can the team learn the interface? What does support look like after go-live? These four questions cut most of the noise. 

Odoo and Exact: two different starting points 

What is Odoo? 

Odoo is a Belgian open-source ERP suite with over thirteen million users worldwide. It is modular: accounting, CRM, sales, inventory, manufacturing, HR, e-commerce, marketing, and website builder are separate apps that all share one database. You start with the modules you need and add more as the business grows. The interface is modern and approachable, which keeps onboarding shorter than most ERP projects. 

What is Exact? 

Exact is a Dutch software company founded in Delft more than forty years ago. It serves SMEs and accountants across the Netherlands, Belgium, and Germany. The core strength is accounting and financial process management, with extensions into project management, manufacturing, and trade. There are several deployment options, Exact Online, Exact Globe+, Synergy, Financials, depending on company size. More than 675,000 companies use Exact to manage finance and operations. 

What does each system cover, side by side? 

Both Odoo and Exact are built as connected modules. Each module handles a specific function, CRM, finance, inventory, project management, and together they form one database for the organisation. The lists below are the components each vendor markets as core. In practice both platforms ship with many more, and the question that matters is not how many modules exist, but which ones the business will actually use. 

Odoo core modules 

• CRM: customer interaction, sales opportunities, reporting 

• Sales: quotes, orders, sales activity management 

• Purchasing: requests for quotation, purchase orders, supplier management 

• Inventory: real-time stock status 

• Project management: time tracking and cost management 

• Accounting: accounts receivable, accounts payable, full financial transactions 

• HRM: recruitment, payroll, leave 

• E-commerce: product management and online payments 

• Marketing: email, social, lead management 

• Website builder: site creation and management 

Exact core components 

• Financial: accounting, financial management, budgeting, reporting 

• Purchasing: RFQs, purchase orders, supplier management 

• Inventory: real-time stock status 

• Manufacturing: production planning, control, quality management 

• Sales: quote management, order processing, invoicing 

• CRM: customer interaction and reporting 

• HRM: payroll, leave, talent management 

• Project management: time tracking and cost management 

• Service management: customer appointments and maintenance planning 

• Business intelligence: advanced analytics and reporting 

Odoo's flexibility lets the system grow with the business, whether you start small or start big. You configure only the modules you need, and add more as the work changes.

What are four real differences between Odoo and Exact? 

Odoo and Exact share a lot of surface area. Both ship modular ERP for SMEs, both run in the cloud, both cover finance, sales, inventory, and CRM. The differences show up once a business starts pushing the system. Four stand out: how modular each platform is, how the interface feels in daily use, what support looks like after go-live, and which kind of business each one was built for. Naming these four upfront is the fastest way to know whether Odoo or Exact is the better starting point for a given company. 

Modularity and flexibility 

Odoo is modular at its core. You activate the apps you need and add more later. Exact is less modular and offers solutions packaged for specific sectors like construction or manufacturing. That makes Exact a faster start for businesses that fit one of those sector packages, but leaves less room for tailoring when the fit is not exact. 

User-friendliness 

Odoo's interface is built around the same design patterns most teams already know from modern web applications. Exact is functional but less intuitive, particularly for non-technical users. For an SME without a dedicated IT team, the learning curve is the bigger hidden cost. 

Support model 

Odoo works through authorised partners like Dynapps, who provide both consultancy and ongoing support. On top of that, Odoo has a large international community active on forums and contributing modules. Exact provides professional support, but only through partners and consultants. There is no equivalent open community to fall back on. 

Target audience 

Exact targets specific sectors, with manufacturing, logistics, and construction the most developed. Odoo targets SMEs broadly, with vertical depth coming from partners. If a business sits squarely in one of Exact's sector packages, that focus helps. If it does not, Odoo's breadth is the safer bet. 

Picked an ERP. Now the real work starts. 

Choosing the system is the easy part. Implementation is where ERP projects either compound value or quietly drain it. A successful rollout depends on the right package, consultants who have done it before, internal buy-in, and a project plan that survives contact with reality. An implementation partner brings the knowledge, the experience, and the support to put the software into the business without breaking the business in the process. It is a partnership, not a delivery. 

Whichever system the business chooses, the work after the contract is where the value gets made. Get the preparation right and the rest follows. Get it wrong and no software, modular or otherwise, will fix it.
