In this eye-opening episode of the Veterinary Business Podcast, margin recovery expert Mark P. Shannon reveals the hidden financial drains quietly eroding veterinary practice profits—from confusing credit card fees to unnoticed vendor markups and auto-renewed contracts. With nearly a decade optimizing payment systems and recovering lost margin for healthcare organizations, Mark explains how most clinics can reduce processing costs by 30–60% without switching software or disrupting workflows. He breaks down interchange optimization in simple terms, shares how routine expense audits uncover thousands of dollars in avoidable costs, and empowers practice owners to regain control of their bottom line, allowing them to reinvest in their teams, patient care, and sustainable growth.
