If you have several Ecwid stores, you can link them all to one Paypal account. Thus, your customers will place orders in your different stores, but the money will arrive to one PayPal account.
Ecwid takes care about proper values for each storefront. All you need to do is enable the Auto return option:
- Log in to your merchant account in the PayPal backend.
- Go to Profile → My selling tools → Website Payment Preferences.
- Set the Auto return option to Enabled.
