I’m currently exploring options for keeping my ERP stable and reliable. I’ve seen providers offering Odoo Maintenance Services and Odoo Support Services, but I’m not fully clear on how they differ or overlap.

Do maintenance services mainly cover bug fixes, updates, and performance monitoring?
Are support services more about handling day-to-day issues and user queries?
For a growing business, which of the two is more important to invest in first?

I’d appreciate insights from those who have used these services for their Odoo systems.
