My business has more than one stores or VAT numbers. Do I have to purchase multiple Cardlink pulse subscriptions?

No. One Cardlink pulse account, i.e. one subscription, can support as many stores (Cardlink MerchantID/MID) as the selected plan allows.

Since the account creation process is different for more than one VAT numbers, you will have to contact the Cardlink pulse team in order to create your account.
