Specialist tour operator seeks management software

We are a specialist tour operator and are looking for management software to support us in our daily work.

The following requirements must be met:

• Manage customers
• Manage bookings
• Enable online travel bookings
• Check capacity utilization
• Independently create and send confirmations, enter them into lists (room occupancy, update customer data)
• Invoice creation, payment control, and dunning
• The software should be easy to integrate into a website frontend (widgets or similar)
• Easy to manage in the backend
• Windows-compatible or web-based

We are planning 1-2 software workstations.
