How to choose between minimum stock rule and make to order? - Odoo 9.0

Minimum Stock rules and Make to Order have similar consequences but different rules. They should be used depending on your manufacturing and delivery strategies.


Minimum stock rule

Minimum Stock rules are used to ensure that you always have the minimum amount of a product in stock in order to manufacture your products and/or answer to your customer needs. When the stock level of a product reaches its minimum the system will automatically generate a procurement with the quantity needed to reach the maximum stock level.

Make to Order

The Make to Order function will trigger a Purchase Order of the amount of the Sales Order related to the product. The system will not check the current stock valuation. This means that a draft purchase order will be generated regardless of the quantity on hand of the product.


Minimum stock rules

The Minimum Stock Rules configuration is available through the menu Inventory ‣ Inventory Control ‣ Reordering Rule in the drop down menu. There, click on Create to set minimum and maximum stock values for a given product.

If the active field is set to False, it will allow you to hide the orderpoint without removing it.
Minimum Quantity
When the virtual stock equals to or goes below the Min Quantity specified for this field, Odoo generates a procurement to bring the forecasted quantity to the Max Quantity.
Maximum Quantity
When the virtual stock goes below the Min Quantity, Odoo generates a procurement to bring the forecasted quantity to the Quantity specified as Max Quantity.
Quantity Multiple
The procurement quantity will be rounded up to this multiple. If it is 0, the exact quantity will be used.
Procurement Group
Moves created through this orderpoint will be put in this procurement group. If none is given, the moves generated by stock rules will be grouped into one big picking.
Lead Time
Number of days after the orderpoint is triggered to receive the products or to order to the vendor

Then, click on your product to access the related product form and, on the Inventory submenu, do not forget to select a supplier.

Make to Order

The Make to Order configuration is available on your product form through your Inventory module ‣ Inventory control ‣ Products (or any other module where products are available).

On the product form, under Inventory, click on Make To Order.

Choice between the two options

The choice between the two options is thus dependent of your inventory strategy. If you prefer to have a buffer and always have at least a minimum amount, the minimum stock rule should be used. If you want to reorder your stocks only if your sale is confirmed it is better to use the Make to Order.
