# How Do I Price My Products?

#### What is a price?

A price is the amount of money you charge for your product or service. When you create a product, you must add pricing information.

Prices are attributed a frequency. You can price your product or service by selecting one of the following:

* One time
* Recurring plan

#### What price frequency should I choose?

Your price frequency depends on the type of product you create.

* If you create a stand-alone product, choose **one time**.
* If you have a product or service that requires a subscription model, choose a **recurring plan**.

By choosing a **recurring plan,** you can set the price and the billing period in which your customer gets charged.

You can choose from the following:

* Weekly
* Biweekly
* Monthly
* Annually

If you sell the same product at different subscription intervals, we recommend creating multiple recurring prices for the same product.

Because a product can have multiple prices associated with it, you’ll need to select which price to use when creating checkout links, invoices, or subscriptions if you want to sell a specific product price to the customer.

**You must always select at least one price when creating a product**

#### How do I select my pricing model?

Pricing models reflect your business revenue model. Zūm Rails offers 2 pricing models:

* **Standard** **pricing**: This means you charge the same price for each unit every time
* **Package pricing:** This means you charge by package (group of units)

{% hint style="info" %}
Package pricing is automatically rounded up. This means, for example, if you charge $15.00 CAD for every 5 units purchased, a customer who purchases 8 units will pay $30.00 CAD.
{% endhint %}
