How do contracts work?

[H5N1]

I've made a company and I bought a contract from Over Seas Imports and assigned a truck but what do I do with the 72k I just plunked down on it? Also should I assign multiple buses to the same route?

Anything but the bus routes you have to transport yourself currently.
Considering the buses, I think it's a better idea to give each their own route (you can also create custom routes or import them).

Did my first contract Bus route today with a small Bus. Payed out very little and you have to micro mange them with repair cost. Wasn't worth it.

Bus routes and cargo contracts are different things.

Bus routes generate income over time when you add your vehicles to them and you have to repair them from the company menu when they break.

Contracts are obligations to deliver a certain amount of cargo to a place, currently you do that yourself using any fitting kind of vehicle.
