Is Upgrading to Odoo 18 Worth It for Australian Companies?
For most Australian organizations, the performance improvements and enhanced compliance features justify upgrading to Odoo 18. The most compelling business cases include:
- Organizations requiring improved Australian regulatory compliance
- Businesses experiencing performance constraints with Odoo 17
- Companies seeking enhanced mobile capabilities for field operations
- Enterprises wanting reduced dependence on third-party integrations
The ideal timing for migration typically falls 3-6 months after release, allowing for community testing and initial stability updates.
What About Odoo 19? Looking to the Future
While this article focuses on the Odoo 18 vs Odoo 17 comparison, it’s worth noting that Odoo 19 is already on the horizon. Odoo 19 is expected to launch during Odoo Experience 2025, scheduled for September 18–20 in Brussels.
For organizations currently considering an upgrade from Odoo 17, this future release timeline creates an important strategic question: upgrade to Odoo 18 now or wait for Odoo 19? The answer depends on several factors:
- Your current pain points with Odoo 17 and whether Odoo 18 addresses them
- The timing of your planned upgrade relative to the Odoo 19 release date
- Your organization’s appetite for frequent upgrades
If your planned upgrade would occur close to the Odoo 19 release date (within 3-4 months), it may be worth waiting to leapfrog directly to Odoo 19. However, if you’re planning an upgrade in the near term, the immediate benefits of Odoo 18 likely outweigh the advantage of waiting over a year for Odoo 19.

Frequently Asked Questions About Odoo 18 Upgrade
When should Australian businesses upgrade from Odoo 17 to Odoo 18?
The ideal time is 3-6 months after the official release, which allows for community testing and initial bug fixes. Organizations with critical business processes should wait for the first stability update, typically released 1-2 months after the initial launch.
Will Australian tax reports and BAS templates work in Odoo 18?
Yes, Odoo 18 includes updated Australian tax reporting templates. Most report formats from Odoo 17 will function, but those using deprecated QWeb elements may require updates. The migration tool provides a compatibility report highlighting affected reports.
How much downtime should we expect during migration?
With proper planning, production downtime can be limited to 4-8 hours for most migrations. This can be scheduled during off-hours to minimize impact. Complex environments with extensive customizations may require longer windows of 12-24 hours.
Can we test Odoo 18 before committing to migration?
Yes, Odoo provides demonstration environments and trial options. Additionally, you can create a duplicate test environment of your current system and perform a trial migration to evaluate compatibility and performance without affecting production.
What are the most significant technical changes affecting Australian customizations?
The most substantial technical changes include enhanced ORM layer performance, updated JavaScript framework components, improved REST API capabilities, and expanded Python 3.10 feature utilization. Australian payment gateway integrations may require minor updates.
Do we need to retrain our Australian staff for Odoo 18?
Most users will find the transition intuitive as the core experience remains similar. However, training is recommended for departments receiving significant feature updates, particularly accounting, manufacturing, and sales teams. Typical training requirements range from 2-4 hours for regular users.
Can we skip from Odoo 16 directly to Odoo 18?
While technically possible, migrating directly from Odoo 16 to Odoo 18 introduces additional complexity. The recommended approach is sequential upgrades (16→17→18) for heavily customized environments. Direct migration is feasible for standard implementations with minimal customizations.
What happens if we don’t upgrade to Odoo 18?
Odoo 17 will continue receiving security updates and critical bug fixes for approximately three years after release. However, you won’t benefit from new features, performance improvements, or integration capabilities introduced in Odoo 18. Eventually, third-party module developers will prioritize newer versions.
How much does upgrading to Odoo 18 cost for Australian businesses?
The cost varies based on implementation complexity. For standard installations, expect to invest 25-40 hours of technical resources. Highly customized environments may require 80-120 hours. Organizations using a certified Odoo partner can request a migration assessment to receive a specific estimate.
Will Odoo 18 affect our existing integrations with Australian payment systems?
Integrations using standard APIs generally remain compatible, though some endpoints have enhanced capabilities requiring minor adjustments. Custom integrations using deprecated methods will need updating. The pre-migration assessment will identify affected integrations.
