# Add-Ons
> Create and manage add-ons.
In Fynn, products can be used as both main products and add-ons,
enabling efficient product management and flexible offerings.
## Benefits
### Efficient Product Management
By using add-ons in Fynn, the product list can be managed more efficiently. There are no duplicates, as products can be defined as both main products and add-ons.
This improves the clarity of the product list and simplifies product management.
### Flexibility in Creating Offers
With add-ons, you can create more flexible offers for your customers. You can offer various combinations of main products and add-ons to meet the different requirements and budgets of your customers.
## Create Add-On
To define a product as an add-on, you have several options:
* **Subscriptions**: When creating a subscription, you can define a product as an add-on by adding it as a "sub-product". This inherits contract terms and notice periods.
For more information, see [Managing Subscriptions](/guide/subscriptions/introduction).
* **Plans**: When managing your plans, you can define a product as an add-on by adding it in the "Add-On" section. You can then set a price for the add-on or use an existing price.
