Anarcho-collectivism and Anarcho-syndicalism to achieve communism?

Hey everyone, so i am more of a market anarchist, but i am trying to understand more about Anarcho-communism, what do you guys think that is the steps to communism? Do you guys think that these 2 branches of anarchism are the main steps to ancom? The labor vouchers and all the trade unions as a transitional stage and a way to achieve an established commune?

Or there are other types of steps that are praxis specifically to communism? Also does different syndicates trading with each other are inherently markets or there are other ways that unions can work together beyond markets or planning together?

Thanks everyone
