Healthcare for your business
Founded in healthcare technology, Medeor® Healthcare Payments are purpose-built to fit seamlessly into your clinical and operational workflows - making payments feel like a natural part of your existing system.
While clinical integrations require caution to protect patient safety, administrative integrations are a smart and strategic move. Medeor® helps protect your profitability by enhancing the patient experience, reducing administrative workload, improving accuracy, and preventing lost revenue.
To give you confidence in every transaction, Medeor® partners with the Bank of New Zealand (BNZ), one of the country’s most established and trusted financial institutions. This ensures your payments are processed securely, reliably, and with the backing of a leading bank.
Whether you're running a busy general medical practice, managing repeat dispensing in a pharmacy, coordinating care in an allied health setting, operating as a specialist with complex billing needs, or overseeing hospital admissions, Medeor® flexes to meet your unique requirements.
Medeor® is more than a payment system - it’s an enabler of better business performance in healthcare.
