Here's how you can make a computed field editable in Odoo by defining an inverse method. This allows users to modify the computed field, and those changes will be reflected in the underlying fields. from odoo import api, fields, models class ProductTemplate(models.Model): _inherit = 'product.template' price_with_tax = fields.Float( compute="_compute_price_with_tax", inverse="_inverse_price_with_tax" ) @api.depends('list_price', 'taxes_id') def _compute_price_with_tax(self): for product in self: tax_rate = sum(product.taxes_id.mapped('amount')) / 100 product.price_with_tax = product.list_price * (1 + tax_rate) def _inverse_price_with_tax(self): for product in self: tax_rate = sum(product.taxes_id.mapped('amount')) / 100 product.list_price = product.price_with_tax / (1 + tax_rate)
