To activate your Paymash online shop
Settings → Account → Options → Activate Online Shop
This option gives you the opportunity to edit or test the webshop.
Good to know: More important than this setting is the adjustment of the subscription. Without the subscription "Webshop" or "All in one" you cannot publish the webshop.
Good to know: If you no longer want to use the webshop, you must also adjust the subscription settings. If you simply deactivate it as described above, you will continue to be charged.
