Cumulative Variant Discount
Sum quantities across product variants to unlock bulk pricelist discounts in Odoo.
Overview
Cumulative Variant Discount changes how Odoo pricelists count quantity for bulk discounts. The standard pricelist evaluates each product variant separately, so a customer who buys several variants of the same product — different sizes or colours — may never reach a quantity break, even though the total order is large.
Built by TechUltra Solutions, the module adds a Cumulative by Product Template option to pricelist rules. When it is enabled, Odoo sums the quantities of all variants of a template and applies the discount once the combined quantity reaches the threshold, instead of treating each variant in isolation.
Prices recalculate automatically as variant lines are added or changed in quotations and sales orders, the same logic carries through to the eCommerce shop, and taxes are computed on the discounted price. The result is consistent bulk pricing across Sales and the website with no custom development.
Key features
-
Cumulative discounts across variants
Quantity discounts apply across every variant of a product template, so mixed orders of sizes or colours still earn the bulk rate in both Sales and eCommerce.
-
Variant-aware sales handling
The module tracks and prices product variations together, giving accurate variant-based pricing across the sales process.
-
Unified pricing for a template
A single, centralised rule keeps discount and pricing logic consistent across all variants that belong to the same product template.
-
Quantity aggregation across variants
Odoo sums the quantities of all variants of a template; when the combined quantity reaches the pricelist threshold, the discounted price applies.
-
Dynamic price recalculation
Prices update automatically in quotations and sales orders as variant quantities are added or changed, always reflecting the current cumulative discount.
-
Sales and eCommerce coverage
The cumulative logic works in the Odoo Sales app and on the eCommerce shop, so customers see the same discounted variant pricing on the website.
-
Tax applied on discounted price
Taxes are calculated on the unit price after the cumulative discount has been applied, keeping order totals accurate.
-
Quick rule configuration
Cumulative discount rules are set up directly on the pricelist with a short configuration, with no customization required.

Setup & configuration
From install to first call — here is the path.
- 1
Install the module
In Odoo, open Apps, remove the Apps filter, search for “Cumulative Variant Discount”, and click Install.
- 2
Configure the pricelist rule
Open the pricelist and add a standard rule with a minimum quantity and price — for example, a fixed price of 50 for a minimum of 50 units.
- 3
Enable cumulative by template
On the pricelist, open the Cumulative by Template tab and switch on the Cumulative by Product Template field to turn on the cumulative discount logic.
- 4
Add variants to an order
Create a quotation or sales order and add lines for different variants of the same template. Odoo sums their quantities against the pricelist threshold.
- 5
Check the discounted price
Once the combined variant quantity reaches the threshold, the discounted price applies and recalculates automatically. The same logic appears on the eCommerce shop.
Frequently asked questions
-
What does Cumulative Variant Discount do?
It makes Odoo pricelists sum the quantities of every variant of a product template when applying quantity-based discounts, instead of counting each variant separately.
-
Why doesn't standard Odoo handle this?
The default Odoo pricelist evaluates each variant on its own. A customer buying several variants of one product may never reach a quantity break, even when the total order is large.
-
How do I turn on the cumulative logic?
On the pricelist, open the Cumulative by Template tab and enable the Cumulative by Product Template field. The rule then sums variant quantities against its threshold.
-
Does it work in the eCommerce shop?
Yes. The cumulative discount logic applies in both the Odoo Sales app and the eCommerce website, so customers see the same discounted variant pricing online.
-
How is tax calculated?
Taxes are calculated on the unit price after the cumulative discount has been applied, so order totals stay accurate.
-
Do prices update as I change quantities?
Yes. Prices recalculate automatically in quotations and sales orders as variant quantities are added or modified, always reflecting the current cumulative discount.
-
Which Odoo versions are supported?
The module supports Odoo 16.0, 17.0, 18.0, and 19.0.
-
Is support included?
Yes. The module includes 90 days of bug-fix support, Monday to Friday, 10:00–19:00 IST.
