# Buying more licenses and upgrading

## How do I buy more licenses for my group subscription?

Only the group administrator can buy more licenses for a group subscription. When an administrator does buy more licenses for the group, an invoice will be generated automatically and emailed to the administrator when the transaction is completed.

If you are a group administrator, to purchase additional licenses click the **Buy more licenses** button. After entering the number of licenses you want to purchase, you'll see a preview of the cost.

## How do I upgrade my group subscription from Standard to Pro?

Only the administrator of a group can upgrade the plan. When an admin upgrades their group, an invoice will be generated automatically and emailed to the lead administrator when the transaction is completed.&#x20;

If you are a group administrator, you can upgrade from a Standard group to a Pro group by clicking **Upgrade Plan**. A cost preview will be provided before you confirm the upgrade.

{% hint style="danger" %}
Please note that only group subscriptions that were purchased on the Overleaf website can upgrade directly from a Standard plan to a Pro plan using this option. Please [contact us](https://www.overleaf.com/contact) if you wish to upgrade the group you administer and do not see this option available to you.
{% endhint %}

## I don't see the option to add licenses or upgrade, what should I do?

Some administrators may not see the upgrade and add license options described here. This can happen if the group was not purchased through the Overleaf website. If you are the administrator of a group and do not see these options, please [get in touch](https://www.overleaf.com/contact) and let us now how you would like to update your group subscription.
