This is something that I suggest retailers go to their industry bodies to enquire as to what is defined as overcharging for surcharges for customers using their credit cards. New laws are coming into effect in a few months that mean that retailers could be fined up to $108,000 per alleged contravention if caught overcharging customers. For more details click here.
Once you have determined your surcharge, let us know as its very easy to change in our system.
