1.) Activate POS Min-Max-Multiple Quantity Feature

This screen shows the Odoo settings where the Min Max Multiple Quantity in POS option can be enabled. Activating this feature allows the POS system to enforce minimum, maximum, and step-based quantity rules during sales. Once enabled, the configuration becomes available on individual product forms.

Navigation : Setting → INKERP → Min Max Multiple Quantity in POS

2.) Set Product-Level Min, Max, and Multiple Quantities

In the product form under the POS tab, users can configure custom quantity rules for each product. Here, you can define the minimum allowed quantity, enable maximum quantity limits, set the maximum allowed quantity, and specify the multiplier step. These settings control how the product behaves during POS order entry.

Navigation : Setting → Products Variants → Product

3.) POS Automatically Applies Minimum Quantity on Product Add

When the product is added to the POS cart, the system automatically fills the minimum allowed quantity (e.g., 10 units). This ensures that cashiers cannot sell less than the required minimum.

4.) POS Adjusts Quantity Based on Multiplier Step

After increasing the quantity, the POS system applies the defined product multiplier (e.g., increments of 5). This ensures the quantity always follows the required step-based increment. Cashiers cannot enter quantities that break the defined multiple rule, ensuring accurate and consistent ordering.

5.) Alert Popup for Maximum Quantity Limit

If a cashier attempts to exceed the maximum allowed quantity (e.g., 30 units), the POS displays a clear Alert popup. The system prevents further quantity increase and informs the user of the allowed limit.
