# Base Amount and Commitment

#### Configuration of Base Amount

> Base amounts allow you to set a minimum amount to be charged in cases of zero consumption. This is only applicable for metered or usage-based products. The base amount is set on the product line item, so you must start with a product line item.

* Go to **Plans & Pricing** → **New plan** → **Add pricing & products** → **Tiered Pricing**
* Add by clicking on **+ Set Base Amount**
* Enter the **amount to be charged** in case of no usage metered
* **Delete** or **edit** by hovering with your mouse

<Tip>
  **Please Note** \
  Base amounts are only applicable for usage products (otherwise it's easier to go for "fixed recurring" pricing). \
  Base amount charges will be added to the customer's invoice according to the plan's billing interval. All amounts are calculated in USD.
</Tip>

#### Configuration of Commitment

> Commitment is the minimum <u>quantity</u> a customer has committed to purchase <u>during the plan lifetime</u>. The commitment is set on the product line item, so you must start by creating a product.

* **Go to Plans & Prcing** --> New plan--> Add pricing & products --> select **Tiered Pricing**
* Add by clicking on **+ Set Commitment**
* Enter the number of units you want to set as your commitment
* **Delete** or **edit** by hovering with your mouse

<Tip>
  **Please Note**

  Commitment can be used for usage products with tiered-based pricing. Commitments are counted in units and calculated based on the price per unit (the defined tier).
