Hi,

I'm trying to see if Odoo can be a solution for my business. The business of my company is to be a broker : to be simple, my clients buy products to supplier, and i take a commission for services rendered in the sale.

For example the client C want to buy one quantity of the product P, the price is 100 euros,  my commission is 8 %, so my invoice to he client C is 8% of 100 euros, so 8 euros. The price 100 euro of the product must be mentionned in the invoice, and of course to total invoiced to the customer, 8 euros.

In odoo if i make an order from the client for the product, i will have an invoice of 100. I would like the calculation of the pricee modified so it is price of product x commission.

So I would like to modify the way the price is calculated in a quotation and order. It seems that i need to create a module which modify the calculation by inheriting the method which do that. My questions are :

1. Should i create a module which will just modify one method ?

2. How can i find the method who do this calulation ? Having the method will help me, but knowing how to find it will help me also for the whole dev i have to do on odoo

Regards

Hi Matz,

In order to achieve this, please follow to following steps:

  1. Create product P as service item.

  2. Enter its Sale Price in product form as 100 euros.

  3. Create a new pricelist to define commission on every product.

  4. In the pricelist->Pricelist Items, choose 'Apply on' as product and select the product P. 

  5. In Compute Price, select 'Percentage (Discount)' and define discount as 92 i.e. 100-'your commission'.

  6. Save the pricelist.

  7. Link the customer(s) with this pricelist.

  8. Now to go Technical->Database Structure->Models and search for sale.order.line.

  9. Create a new field 'x_product_price',name it Product Price and enter 'product_id.lst_price' in the 'Related field' field.

  10. Now add this custom field in your sale order form.

  11. Accordingly you can add the field in your Sale Order/Quotation report as well.

Hope it will help you to achieve your goal without writing any python code.

Hi Waqas,


It is working really well. I thank you very much, it is a very good way to do what i want without any python line code ! 

One question : i need the product price to be on the invoice too. I modified the model of account.invoice.line and added also x_product_price,  related field product_id.lst_price like on sale.order.line. I also modified the views account.invoice.line.tree and account.invoice.line.form  like for the order. But on the invoice, i don't have the price of the product shown. Where am i wrong ?


My account.invoice.line.form is like this with the new field :


<?xml version="1.0"?>
<form string="Invoice Line">
                    <group>
                        <group>
                            <field name="product_id" context="parent and {'partner_id': parent.partner_id}"/>
                            <field name="x_product_price"/>
                            <label for="quantity"/>
                            <div>
                                <field name="quantity" class="oe_inline"/>
                                <field name="uom_id" class="oe_inline" groups="product.group_uom"/>
                            </div>
                            <field name="price_unit"/>
                            <field name="discount" groups="base.group_no_one"/>
                            <field name="currency_id" invisible="1"/>
                        </group>
                        <group>
                            <field domain="[('company_id', '=', parent.company_id)]" name="account_id" groups="account.group_account_user"/>
                            <field name="invoice_line_tax_ids" context="{'type':parent.get('type')}" domain="[('type_tax_use','!=','none'),('company_id', '=', parent.company_id)]" widget="many2many_tags" options="{'no_create': True}"/>
                            <field domain="[('company_id', '=', parent.company_id)]" name="account_analytic_id" groups="analytic.group_analytic_accounting"/>
                            <field name="company_id" groups="base.group_multi_company" readonly="1"/>
                        </group>
                    </group>
                    <label for="name"/>
                    <field name="name"/>
                </form>
