# Make changes to contract services

Changing a contract's terms of provision may involve changes in services, prices, or
quantities.
You can add or delete services, change the included quantity, or apply a discount.

Note that you can change the set of provided services for contracts that are based on templates
that allow overriding of contract items.

Contract upgrades and downgrades are performed in two stages: preparation and activation.

During the preparation stage, you modify provisioning terms, but contract invoicing and service
provision are performed according to the initial settings of the contract. When the changes are
activated, contract invoicing and service provision are performed according to the new settings.

You use the Customer contracts (CT301000) window to change services of a contract with the **Active** status as follows:

1. Go to the [Customer contracts (CT301000)](https://docs.vismasoftware.no/visma-net-erp/help/customer-ledger/customer-ledger-windows/customer-contracts-ct301000/index.md) window.
1. In the **Contract ID** field, select the contract you want to upgrade.
1. Click **Actions**, and select **Upgrade contract**.

    This gives the contract the **Pending upgrade** status, which means that you can change the terms of provision.
1. On the **Details** tab, modify the list of services or their quantity, or apply a discount.
1. Click ![icon-save](https://docs.vismasoftware.no/media/visma-net-erp/icon-save.png).
1. Click **Actions**, and select the **Activate upgrade** action. In the **Activate contract dialog box**, specify the date of contract activation and click **OK**.

    If the operation is completed successfully, the green check mark appears in the window toolbar.
