We show that morphisms from n homotopy unital $A_\infty$-algebras to a single one are maps over an operad module with n+1 commuting actions of the operad $A_\infty^\hu$, whose algebras are homotopy unital $A_\infty$-algebras. The operad $A_\infty$ and modules over it have two useful gradings related by isomorphisms which change the degree. The composition of $A_\infty^\hu$\n-morphisms with several entries is presented as a convolution of a coalgebra-like and an algebra-like structures.
