Taxi company seeks billing software (invoicing)

For my taxi company with two operating locations, I am looking for billing software that also supports the billing of medical transport.

The software should meet the following requirements:

• Health insurance billing
• Support for calculating co-payments (including co-payment invoicing)
• Invoicing for all customers
• Billing
• Purchase solution, local preferred over web-based, rental solution

Our tax advisor handles payroll accounting.

One software workstation is planned. We work with an MS Windows system.
