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.
