# Connect payment & accounting apps

Connect a payment provider so you can take payments through the Point of Sale, and link your accounting system to keep your books in step.

| 📍 **Where to find this:** Left navigation menu → Apps → Billing/Payment

## ✅ What you can do

- Connect Stripe to take card payments online
- Connect Fortnox to manage invoices
- Connect Swish for mobile payments
- Connect Viva Wallet for card and Klarna payments
- Enable manual payments for transactions taken outside MERIDIQ

## 💳 Available integrations

| Integration | What it does | Available in | Price |
| ---- |
| Stripe | Accept online payments — connect your account for secure card payments | Most countries | Free |
| Fortnox | Integrate with Fortnox to manage invoices | Sweden only | Free |
| Swish | Support Swish payments from your clients | Sweden only | Free |
| Viva Wallet | Handle card transactions and Klarna payments | Sweden and the Netherlands | Free |
| Manual Payment | Register a transaction in MERIDIQ while taking payment outside the system | Everywhere | Free |

|| ℹ️ You only see the integrations available in your clinic's registered country, so the Billing/Payment tab looks different from clinic to clinic. Your country is set under **General Settings → Company information**.

|| ℹ️ **Klarna is not a separate integration.** It comes with Viva Wallet — connect Viva Wallet and Klarna becomes available as a payment option.

## 🔗 Connect a payment method

1. Click **Apps** in the left navigation menu.
2. Open the **Billing/Payment** tab.
3. Click **Activate** on the integration you want to connect.
4. You are taken to **Point of Sale System → Settings → Payment methods**, with your chosen provider already selected.
5. Follow the provider's steps to authorise the connection.

||| ⚠️ These integrations need an active **Point of Sale** subscription. Without one, the app card shows a **Subscribe to Point of Sale** button instead.

|| ℹ️ Some clinics must also complete **Infrasec registration** before payment methods can be connected. If that applies to you, the app card prompts you to connect Infrasec first.

## ✅ Check what is connected

Integrations you have already connected show **Active** and a settings icon, instead of the **Activate** button.

| 💡 To take a payment once a provider is connected, see the [POS (Point of Sale System)](https://help.meridiq.com/en/category/pos-point-of-sale-system-18cyi7m/) section.
