Pros & Cons
Odoo

Pros

- It is open source and highly customizable through Studio, the API, or self-hosting.
Cons
- Reviewers often describe the interface and workflows as complex for new users.
- Setup usually needs internal staff or a paid implementation partner.

ONES

Cons
- There are very few independent reviews: about 13 on G2 and 9 on Capterra.
- G2 reviewers mention a learning curve for new users.
- Its third-party integration catalogue looks small next to Jira's or monday.com's.
- Gantt charts and automation need a paid plan, and resource scheduling needs Business.
