Hi,

Odoo Studio is partially suitable for customizing business documents, excelling at simple tasks like adding/removing fields, rearranging layouts, changing labels, and adding basic text/images. However, it falls short for complex layouts, custom logic/calculations, data model modifications, and advanced reporting features. While Studio offers a GUI, understanding QWeb templates remains beneficial.

For simple customizations and non-technical users, Odoo Studio is a good option, but for complex needs, hiring a developer to modify QWeb templates directly is recommended. Alternatives include Odoo's reporting engine and third-party reporting tools. Consider your requirements and technical expertise when choosing a customization method.
