Which crm to choose for the organization of passenger transportation?

Question

CRM

Advise the CRM engine, the task is actually this, there are passengers, there is transport, I am generally a system myself. admin, you need to automate the process so that you can see how many seats are on the bus (filled-free) and print documents from there and so on, I didn’t find any ready-made solution, is there? I may not be looking there
