# How to add the order-sync add-on
### :memo-circle-check: Before you start
**You’ll need**
* The Standard Marketplaces module
**Good to know**
* All order connections that go to the same seller account will count as one order connection.
* The costs for the order process are €49 per active unique order connection per month (or $59 with a Shopify plan)
### Add the Order sync add-on
1. In your **Channable account**, go to **\[company name] > Plans & Pricing**.
2. Click **Continue to additional modules**.
3. In the **Marketplaces** section, find **Order sync** add-on. Click the + icon for each marketplace you want to use.
4. Click **Complete subscription**.
From here, you continue by setting up your order connection(s).
**Example**
If you have a Magento webshop connection and want one order connection for Cdiscount and one order connection for bol, you will need to add two order connections (€49 + €49 = €98) in addition to your Marketplace Standard subscription cost.
