Question 1

What's the difference between Odoo Studio and custom modules?

Accepted Answer

Odoo Studio is a no-code, drag-and-drop tool included in Odoo's Custom plan. It lets you add fields, create approval flows, and build conditional logic without writing code. Studio handles about 70% of business needs: basic workflows, custom reports, branded documents. Custom modules are Python-based extensions for everything Studio cannot handle: complex business logic, real-time system integrations, high-volume data processing, and industry-specific workflows. Choose Studio if the feature is simple; choose custom modules if you need business logic Studio's visual tools cannot express. Many businesses use both.

Question 2

How much does it cost to build a custom Odoo module?

Accepted Answer

Cost depends on scope and complexity. To use custom modules at all, you need Odoo's Custom plan (€29 to €37.40 per user per month). If you choose Odoo.sh for hosting, you pay extra on top of your subscription; exact Odoo.sh pricing requires contacting Odoo sales. Self-hosted deployments on your own VPS cost less per month but require in-house DevOps expertise or hiring contractors to manage staging, backups, upgrades, and monitoring. Managed hosting like Opsily includes all of this in one transparent monthly price, removing variable costs and deployment complexity.

Question 3

Do I need Odoo.sh to deploy custom modules, or can I self-host?

Accepted Answer

You have three options. First: Odoo.sh (Odoo's Git-integrated CI/CD platform) handles staging, automated testing, deployment, and backups. It costs extra on top of Odoo subscription with variable pricing (contact Odoo sales). Second: self-hosted on your own VPS (cheapest monthly cost, but requires in-house DevOps knowledge or hiring contractors). Third: managed hosting (like Opsily) where a provider manages the infrastructure, backups, and deployments for you with transparent, all-in-one pricing. Choose based on your team's DevOps skills and budget.

Question 4

Is it cheaper to hire a developer or use Odoo Studio?

Accepted Answer

If your need is covered by Studio (new fields, approval flows, conditional logic), use Studio, it is included free and ships fast. If your need requires code (API integration, complex business logic), you must hire a developer. There is no cost comparison: Studio is free if it works; custom modules require hiring. The real question: Can Studio solve this need? If yes, use it. If no, invest in a custom module.

Question 5

How do I get started with custom modules on Opsily?

Accepted Answer

Sign up for an Opsily managed Odoo hosting plan (Small, Medium, Large, or Unlimited). Connect your Git repository (GitHub, GitLab, Bitbucket) where your custom modules live. Opsily auto-detects your module code, builds it, and deploys to a staging environment. Test your changes in staging, approve, and deploy to production in one click. Rollback is instant if needed. Opsily handles backups, monitoring, and version upgrades automatically.

Question 6

Can I migrate my existing Odoo custom modules to Opsily?

Accepted Answer

Yes. If your custom modules are version-compatible with Opsily's Odoo instance, migration is straightforward: push your code to a Git repository, configure Opsily to pull from it, and deploy. Opsily also migrates your Odoo database (all your live data) and installed third-party modules. If your modules were built for an older Odoo version, we can help assess compatibility and plan updates. Contact our team for a custom migration quote.

Question 7

How does Opsily secure my custom Odoo modules and data?

Accepted Answer

Opsily hosts Odoo on German servers with GDPR compliance. All data is encrypted at rest and in transit. We run automated backups daily, stored securely in a separate region. Your modules are isolated in a secure container; no other customer can access your code. We monitor for security patches and apply them automatically to Odoo and system dependencies. You retain full ownership of your custom module code, we are just hosting it.

Question 8

What happens when Odoo releases a new version? Do I need to update my custom modules?

Accepted Answer

Odoo releases major versions yearly (Odoo 17, 18, 19, etc.). Your custom modules should be updated to work with the new version, usually a small maintenance task, but critical to stay supported. Opsily can help coordinate version upgrades: we test your modules in staging on the new version, notify you of compatibility issues, and help schedule production upgrades with zero downtime. This maintenance cost is much lower than self-hosting, where you would do it all yourself.

Question 9

Can I use third-party Odoo modules (from the Odoo App Store) alongside my custom ones?

Accepted Answer

Yes. Opsily supports installing both first-party Odoo apps and third-party community modules from the Odoo App Store. You can mix and match: use Studio for quick customizations, third-party modules for industry solutions, and custom modules for unique business logic. All three coexist in the same Odoo instance.
