Extra activity fees are only applied when you have used up all of your free activities and process more e.g. your business is on the Bronze plan and uses the Secure Batch Drive to process 50 payments from your regular customers; your team also uses Invoices to receive a further 80 payments throughout the year, bringing you to a total of 130 activities. You will only be charged the extra activity fee for the last 30 payments, since the Bronze plan includes 100 free activities. Our plans all include free activities.
