We use Vaxcare here in Fort Collins also and we love it. We do not have to purchase the vaccines vaxcare takes care of it and will also reorder automatically once your inventory gets low. Yes if the patient has insurance they will bill the insurance company. They even have an eligibility check for you when you check the patient into their system. They reimburse you for each administration. Their cash pay pricing for patients who do not have insurance is very good, very affordable! Also I have to say their customer service is amazing, our rep always gets back to me right away, set up was super easy and the rep comes to your clinic to teach your staff how to use the system. I definitely recommend them!
