# Cart form
A **Cart Form** lets you collect extra information from customers *before* they checkout, like special instructions, order notes, gift messages, etc. With Powerful Contact Form Builder you can build a cart form fast, then attach it to your store cart page.
### ℹ️ Before You Begin
* Cart Form is available only on the **Premium plan (or higher)**.
* Each store can create **only one cart form**.
* Cart Form works with your theme’s **default cart page**. If you use a custom checkout flow or non-standard cart template (via a 3rd-party app), cart form may not work correctly.
### 🧩 How the Cart Form Works
#### 1 — Customer fills in the Cart Form
When shoppers are on the **cart page**, they see your cart form fields — for example:
* “How did you hear about us?”
* “Delivery date”
* “Message”
* “Agree to terms & conditions”
#### 2 — The form is submitted when the shopper clicks **Checkout**
Unlike a normal form, customers do not press a “**Submit**” button.\
The form is automatically submitted the moment they click the **Checkout** button.
#### 3 — You can view the Cart Form data inside the order
When the order is placed, the cart form answers appear inside the **Additional Details** section of the Shopify order page.
