Open-source ERP vs proprietary ERP
Source availability can affect auditability, extension and supplier choice. It does not remove the cost of operating, securing, upgrading and supporting a system. Proprietary products may offer managed features or support that better match a team’s constraints. Datrylo uses Odoo Community and publishes this guide with a commercial interest.
A decision worksheet to reuse
Adapt this buying checklist to your team, priorities and budget.
| Decision field | Worked example and evidence to request |
|---|---|
| Software licence | Record exact code, version, licence, permitted changes and notices. Open source provides rights under its licence; a proprietary subscription provides the contracted usage rights. |
| Hosting and operations | For either model, name the operator, environment, capacity and service responsibilities. Access to code does not supply a hosted runtime or an operations team. |
| Maintenance and support | Example worksheet: customer finance owner tests a release; the named service operator applies agreed updates; the support contract specifies channels and response commitments. Do not assume free lifetime maintenance. |
| Customisation and exit | Compare change cost, ownership/licence, upgrade effort and a usable data export. Preserve third-party copyright and provenance. Request a scoped service quote rather than equating licence price with total cost. |
Compare the whole service
Ask who can inspect or modify each component, which licence applies, how updates are delivered, who tests custom modules, and what happens if the vendor relationship ends. Separate the software licence from hosting, implementation, integrations, backup, recovery and support. Require a current export and restore demonstration, not only a statement of ownership.
Odoo publishes its edition boundary. Datrylo’s independent management and add-ons create their own maintenance and service obligations. Neither open source nor proprietary status proves fit, security or portability. Read the open-source disclosure and plan an exit path.
