Getting started with Odoo 18 comes down to two decisions: where it runs and what you install. Hosting is Odoo Online, Odoo.sh or your own server; the edition is Community, which is free and open source, or Enterprise, which is a paid subscription adding apps such as Accounting, Helpdesk, Documents and Studio. Install the two or three apps you actually need first and add the rest later.

Just sign up and start!
✅ Best for: Startups, small teams, non-technical businesses.

- Odoo still handles the server, backups, and scaling.
✅ Best for: Growing businesses that need customization without full server management.
🎯 Pro Tip: Think of Odoo.sh as the "sweet spot" between full DIY and full SaaS!
🖥️ Option 3: On-Premise (Self-Hosted)
Host Odoo yourself:
On your company servers
Or using cloud providers like AWS, DigitalOcean

Questions we get asked
What is the difference between Odoo 18 Community and Enterprise?
Community is the free, LGPL-licensed edition and includes CRM, Sales, Invoicing, Inventory, Manufacturing, Employees, Project, Website, eCommerce and Discuss, among others. Enterprise is a paid subscription that adds apps licensed OEEL-1, such as full Accounting, Helpdesk, Field Service, Documents, Sign, Marketing Automation, Planning, Appraisals, Payroll and Studio, plus the Enterprise web client and upgrade support.
Which hosting option should I pick for Odoo 18?
Odoo Online is the fastest start and Odoo handles updates and backups, but you cannot install custom code. Odoo.sh is a managed platform where you keep your own Git repository, get staging branches and can deploy custom modules. On-premise gives you total control of the data and the code, and hands you responsibility for updates, backups and security.
Can I install custom modules on Odoo Online?
No. Odoo Online runs Odoo's own code, so third-party and custom modules cannot be added there; customisation is limited to configuration, automation rules and Studio. If you need custom Python or a community module, you need Odoo.sh or your own server. Databases can be moved between the three options, which is why many businesses start on Online.
How many apps should I install at the start?
Start with the apps that map to a process you are already running badly, usually CRM, Sales and Invoicing, and add the next one only once the first is genuinely live. Odoo installs dependencies for you, and every extra app brings menus, fields and access rights your team then has to ignore. You can install more at any time.
Is Odoo 18 Community really free?
Yes. Odoo 18 Community is published under the LGPL-3 licence, so you can download, run and modify it without paying a licence fee; you pay only for hosting and whatever help you choose to buy. Costs appear when you need an Enterprise-only app, the official upgrade service or Odoo's support, all of which come with the Enterprise subscription.
