Apply a payment template to your site
Go to Add-ons > Store > Settings > Payment types
where you define the payment templates applied to your store.
You will create multiple payment templates if you want to propose different payment methods for the multiple zones. Each zone will need to be created beforehand, if not you will need to create your zones by going to the menu Add-ons > Store > Settings > Zones.
You can propose to pay by charge card for all the zones configured and then add the option to pay by check to a certain zone. For instance, it is standard to propose payment by check in the zone of your bank, as some checks can not be endorsed internationally.
