Answers to frequently asked questions on surcharging in Cornerstone. For general surcharging FAQs, visit software.idexx.com/surcharging-faq.
What is surcharging?
Surcharging is the practice of adding a fee to a credit card transaction to recover payment processing costs. It is a legal and regulated alternative to raising prices in many states and is subject to strict rules by Visa, Mastercard, and other card networks.
Consider the following before implementing surcharging at your practice:
- Pet owner perception and how the front desk will address their concerns.
- State-specific laws and regulations, including disclosures.
Example: What cards can be surcharged, and by how much. - Typically, surcharging requires passing a higher fee to customers than what practices pay.
