I made my SaaS but I'm stuck at pricing

About a year and a half ago, I launched the beta of my first SaaS application, which is a hospital management software. However, now that I want to publicly launch it, I'm stuck at pricing. I'm not sure how much to charge, what would be a fair price. I'm thinking of a per user per month pricing model. If you're someone in the medicare industry, what do you think would be a fair price.

For your reference, here are some of the features that are currently available:

1. Patient management
2. Doctor/Staff management (including salary)
3. Finance (keeping track of income and expenses)
4. Lab test management
5. Inventory management
6. Prescription composition (basically create and print prescriptions in pre-built or custom templates)
