# Add one-time products

Add an extra product to one or more upcoming subscription orders without making it recurring, and change or reset items on a single order.

Last updated: 2026-10-18

A one-time product ships with a chosen order and is charged once. It doesn't become part of the subscription. Use it for a free gift, a sample, or something a subscriber asked to add. Open **Subscriptions → Manage → Contracts**, choose the subscription and go to **Upcoming orders**.

## Add a product to upcoming orders

1

#### Open the dialog

Choose **Add one-time product**.

2

#### Choose the product

Pick it in **One-time product**.

3

#### Choose the orders

Under **Add to these orders**, tick the next order and any later dates. You can choose up to 6 orders at a time. The dialog shows what it adds to each order and the total before tax and shipping.

4

#### Confirm

Choose **Add to this order** or **Add to N orders**. Each order shows **Added**, **Not added** or **Couldn't confirm**. If some failed, choose **Try again** for those orders.

Every-order changes wait

Until the last order you added to has been charged, changes to the subscription itself (swapping products, a new address or a new frequency) can't be saved. The dialog tells you the date.

## Change items on one order only

Under **Products in next order** (or on a cycle in **Future billing cycles**), each line has buttons that only affect that order. One-time lines carry a **This order only** badge.

*   **Edit for this order**: set the **Quantity for this order** and **Unit price**, then **Save for this order**.
*   **Properties**: edit the line item properties for this order.
*   **Remove from this order**: take the item off this order only.
*   **Reset order changes**: shown when the order is marked **Customized order**. It removes every change made only for this order, including one-time products, prices, properties and shipping overrides.

## Other ways one-time products get added

*   **Subscribers** can accept an offer in the portal with a button like **Add to next order**. See [Upsells for subscribers](https://chargezen.com/docs/subscriptions/upsells).
*   **Workflows** can add one automatically with the **Add one-time product** action, for example a gift on the third order. See [Workflow automations](https://chargezen.com/docs/subscriptions/workflows).
*   **Quick actions** in emails include **Add one-time product to the next order**. See [Quick actions](https://chargezen.com/docs/subscriptions/quick-actions).

## Troubleshooting

### The button is missing on a prepaid subscription

One-time product changes aren't available for prepaid renewals.

### What happens to a one-time item if the order is skipped?

It stays with the skipped order and is only charged if you restore that order.

### What happens if I move the next charge date?

When the new date lands on a later order, Chargezen asks whether to move the one-time items to the new date or leave them off.
