The choice is up to the client. With whom do you want to get involved, with one of us or both? Of course, the choice is yours! Depending on the type of assignment you can indicate if you want to use one of us or both. If you find it difficult to assess this, we gladly first consult with you to determine jointly what is most efficient. Naturally the location can also play a role in this. Something you will otherwise hardly notice in practice!
