Odoo Version: 19 Community

Use Case

I'm setting up Odoo for a roofing contractor. They need to create quotations for services like "Velux window installation" where a single line item is actually composed of:

Materials:

• Velux roof window
• Flashing kit
• Insulation material
• Screws/fasteners

Labor:

• Installation time (e.g., 8 hours × hourly rate)

Requirements

1. Customer view: The customer should only see ONE line item with a total price (e.g., "Velux Window Installation - €1,850.00")
2. Price calculation: The price should be calculated dynamically from the sum of all components (materials cost + labor hours × hourly rate)
3. Internal view: Internally, we still need all details for inventory management and accounting

What I've researched

• Kit products with Phantom BoM: Works for materials, but services cannot be added as BoM components
• Odoo 19 Sections with "Hide Details": Seems promising, but I'm not sure if this calculates prices dynamically or just hides the display
• OCA Product Pack: Not yet available for Odoo 19

My Questions

1. What is the recommended approach in Odoo 19 to achieve this?
2. If using Sections with "Hide Details" - does the section automatically sum up all line items as a subtotal that the customer sees?
3. Is there a way to save this as a template/product so the contractor doesn't have to manually add all components for each quotation?
4. Any experience with third-party bundle modules that work well with Odoo 19 and support services?

Thanks in advance for any guidance!
