"Natürlich haben wir eine Alternative."

Translation: Of course we have an alternative.

Why are the "haben wir" swapped even there is no time frame, or is there more rules?

[quis_lib_duo]

In a declarative sentence the verb needs to be in second position, hence the subject moves to third here.

[Hannibal-Barkas]

you could say "wir haben natürlich eine Alternative"
