To let clients and contacts pay invoices online, you can add a **Pay Invoice** button to your invoices.

1. Go to **Settings → Invoices**.
2. Click **Connect Stripe** (if Stripe is already connected skip ahead to step 3), then follow the prompts to create a new Stripe account or connect an existing one. \
   \&#xNAN;***Stripe** is the secure payment processor Caspen uses for handling online credit card payments.*&#x20;
3. Turn on **Online payments**.

Once enabled, invoices you send to clients or contacts will include a **Pay Invoice** button so they can pay by card.

## **Sending an invoice for online payment**

After you create an invoice, you can send it so your client can pay online. You can send invoices in two ways:

* **When finalizing the invoice**
* **After finalizing the invoice**

#### Option 1: Send when finalizing the invoice

Before finalizing:

1. Confirm **Email invoice** is selected (you can untick this if you prefer to send it later).
2. Select an **Email template**.

When you click **Finalize invoice**, Caspen sends the invoice to the client or contact shown under **Invoice to**.

#### Option 2: Send after finalizing the invoice

1. Open the finalized invoice.
2. Click **Send invoice**.
3. Review the email template, subject, and message body.
4. Click **Send**.

**Note:** You can also share the invoice link instead. On the finalized invoice, go to **Actions** → **Copy public link**, then send the link to your client.

{% hint style="warning" %}
**Reminder:** The **Pay Invoice** button only appears when **Stripe** is connected and **Online payments** is enabled (**Settings → Invoices**).
{% endhint %}

## What your client sees

When a client opens the invoice online, they will see a **Pay Invoice** button.

They can enter their card details and click **Pay** to complete the payment. Once the payment is successful, it’s automatically applied to the invoice and the invoice status updates to **Paid**.
