Annual fee payment

Hello everybody
I want to create an annual fee. It is a fee for stores that want to connect only the POS for credit card transactions.
it’s possible?

Hello Alessandro,
please create a ticket with a full description of how this fee should be applied.

As far as i understand customer will be charged for extra fee 10(for example) if he/she paid an invoice with credit card only? If paid with cash or bank transfer this fee shouldn’t be applied?

Hi Mykhailo
it’s not right… I create a support tiket and I’ll explain you better.
