Hi,

Odoo can handle your hardware maintenance workflow very well, using mostly the Repairs and Sales/Invoicing modules, with a few customizations to match your stages.

On Odoo (v17 or v18, Community or Enterprise):

               - Repairs (repair) → core module for creating and tracking repair orders

               - Sales → to create quotations/estimates for repairs

               - Invoicing → to handle payments

               - Inventory → to track spare parts

               - Helpdesk(Optional) → if you want to log repair requests from customers online

You can also use the following module.
