Odoo - free or licensed?

If you're looking for software to help you manage your company, you've come across Odoo, and you're facing the dilemma of "Is it worth paying for an Odoo license? There's a free version available!" - this article is for you. Lots of people ask themselves this question - after all, why pay for something you can get for free. So how does it actually work with Odoo? What does the free version offer, and what does the licensed one offer? Is Odoo Enterprise just hosting for the free version?

You surely know that in today's world nothing is truly free... and if it is, it comes with costs that aren't obvious at first glance. There's no exception to that rule, and that includes Odoo (and any software or service, for that matter).

Choosing the free edition mainly means server maintenance costs, database costs, update costs, security patch costs, and backup costs. It's also the cost of time and money lost developing custom modules (if the Enterprise - licensed - version already offers that functionality).

There's no single right answer to the question "Is the free version or the paid one better?" It's worth understanding what the Enterprise version offers, as well as the costs tied to running Odoo Community over the long term.

I've described how to approach this below.

Does Odoo Enterprise Include More Modules Than Community?

Odoo Enterprise vs. Community - the Differences

Yes. The differences between Odoo Community and Odoo Enterprise are huge. Odoo Enterprise SaaS isn't just plain Odoo with a per-user, server-access fee tacked on.

Odoo Enterprise gives you access to many modules that aren't available in the Community version. Most of the modules in the Enterprise version are expanded compared to the Community version. A few examples?

These are just a few examples. Maybe these aren't the modules you care about, and Odoo Community will be entirely sufficient for you. Think it through before making a decision.

You can move from Odoo Community to Odoo Enterprise, but that will be an additional cost down the road.

Server and Odoo Maintenance?

Server - Is It Just a Hardware Cost?

Many people choose Odoo Community because, after all, it's free, and they already have a server at their company where they can host Odoo. You need to make sure the server is fast and powerful enough to support many users working at once without the system lagging. Nobody likes working with software that keeps freezing, right?

If you have your own server that's up to the task, you still need someone to maintain it. Installing, configuring, and maintaining Odoo are variable costs. Availability is very important here - Odoo Enterprise SaaS offers 99.9% uptime.

Consider the cost of Odoo Community going down during a workday. Will your server maintenance specialist respond right away? How many people will be waiting for the system to be restored to a reasonably usable state?

If you're running your own server, take into account:

Database - How Much Is Your Data Worth?

The server isn't the only cost. Data is stored in a database - PostgreSQL, in Odoo's case. You need to make sure the database is backed up - ideally on a separate instance (the database itself should also be on a different server than Odoo!) - so that if one server fails, you can recover the database with minimal data loss.

Odoo Enterprise SaaS replicates database backups across three servers in different locations. The SLA specifies a maximum data loss of 24 hours, but notes that for SaaS, data loss should be close to zero.

With Odoo Community you also have the option to configure this yourself. Just remember that you'll need to bring in a specialist to do it. Responding to an emergency also costs money. So does making sure the backup server never runs out of space. The same goes for an SLA - these are typically fixed costs.

For the database, factor in:

Cybersecurity

Is your server correctly configured and secured? If it's a server exposed outside your local network - for example because you're hosting a website on Odoo - you need to make sure it's secured and kept up to date. Data loss is costly.

Remember that cybersecurity isn't just about someone stealing data from the database. What if someone launches a DoS attack against you? Will your infrastructure handle an attack on the website? This matters for Odoo, because it's the same server that provides the application for your employees. If it gets overloaded due to an attack, employees - internal application users - will feel it too.

For digital security, factor in:

Maintenance and Updates

Keep in mind that software is constantly evolving. New functionality is usually added to new versions, and old versions gradually lose their "shelf life" (no updates, no development, no security patches).

With Odoo Enterprise you get a free tool for upgrading Odoo versions. The upgrade is dead simple - all you have to do is check your data after the update. And here's another important point: if any problems come up, Odoo fixes them once you report them (they work pretty efficiently - I've reported bugs to them more than once). It's like having a free specialist!

Support in the Enterprise version goes beyond migration. Any bug that's found gets fixed once it's reported and verified. With Community - you have to hire someone, or file an Issue on GitHub.

For maintenance, factor in:

Summary

I didn't want to sound overly dramatic, and it may look a bit like Odoo Community is a bad idea. It isn't! The software works, but when someone installs it, it's often left unattended until the owner is forced to update it.

It's worth thinking carefully about whether it wouldn't be better to spend those 50 zloty / user and ensure business continuity. IMPORTANT! Odoo offers individual modules for free, for an unlimited number of users. Maybe you only need one module for your use case?

Below is a summary table of what to pay attention to:
Odoo Community (Self-Hosted) Odoo Enterprise (SaaS/Cloud)
Infrastructure (Server) Your own server or VPS. Full responsibility for the hardware and operating system. Included in the license. No need for your own infrastructure.
Database (PostgreSQL) Manual configuration, optimization, and performance monitoring of the database. Fully managed by Odoo. Optimized for performance.
Backups You have to set them up yourself (ideally on an external server) and test that they work. Automatic, replicated across 3 different data centers.
Availability (SLA) Depends on your server provider and your administrator. Guaranteed 99.9% availability from Odoo.
Security (Patches) You have to manually track security bulletins and roll out patches yourself. Automatic and immediate rollout of critical security patches.
Version updates (Upgrade) A manual process, often requiring complex data migration by a specialist. Included. Access to a dedicated migration script that eases the move to a new version.
Maintenance costs (IT) High cost of Linux/Odoo administrator "man-hours." Low - most administrative tasks fall on the provider.
Technical support No vendor support. You rely on forums or paid partners. Direct technical support from Odoo for system bugs.
Cybersecurity Requires your own firewalls, WAF systems, and DDoS protection. Advanced protection of Odoo's infrastructure (WAF, DDoS protection) included.
