# Recurrent products

Any product can be sold as a one-off or as a recurrent sale by administrators but, when setting up the product, you can indicate if customers can buy the product via the members portal as a one-off, as a recurrent purchase or both.

A recurrent product can be invoiced every any number of days, weeks, months, or years. In addition to this, you can also set the product to be invoiced every time the main contract of the customer is invoiced, effectively linking the billing cycle of the product to that of the contract for that customer.

Examples of items you may want to sell as recurrent products include parking passes and locker rentals. To allow a product to be purchases on a recurrent basis, open the [advanced options](/platform/day-to-day/inventory/managing-products/product-advanced-options.md) for the product. In **Available as**, ensure **Both as recurrent as one-off purchase** or **Only as recurrent** is selected.

In contrast to a contract, which makes a customer a member, selling a recurrent product will not make a customer into a member. Even though this customer will be invoiced for that product automatically based on the billing cycle you set when selling the recurrent product, they do not have a contract and are not a member. 

For example, you may have 

* a customer who purchases 5 day passes every month, so they always have a valid pass for days they want to check into your location.
* a customer who purchases 10 days passes every 3 months because they are only in town for several days per quarter.

{% hint style="info" %}
You can only sell recurrent products to contacts via the admin panel, contacts cannot purchase recurrent products on the members portal.
