Services that have their Invoicing Policy defined as Based on Delivered Quantity (Manual) can be manually delivered by updating the Delivered field on the Sales Order Line.

Hi,

The delivery status in Odoo is typically tied to the delivery orders (shipping) generated for shippable products. Since services don't involve physical shipments.

Refer to the code:

from odoo import models

class SaleOrder(models.Model):

    _inherit = 'sale.order'

    def _compute_delivery_status(self):

        super()._compute_delivery_status()

        for order in self:

            # If order ONLY contains services → mark as delivered

            if all(line.product_id.type == 'service' for line in order.order_line):

                order.delivery_status = 'delivered'

Hope it helps.
