Payment before or after completion of the construction phase?

Of course, that also depends on how confident your provider feels.

Nope.

Why? Do you really think that something will go through the human route then?

You have such a cute dog, we will adjust the schedule according to your wishes.

Why? Do you really think that anything runs on the human side then?

Something only "runs" if the control center agrees. Cute four-legged creatures don't change anything about that.

Of course, in such matters the headquarters will be the central point of contact. Funny pun. For the initial customer consultation, the payment plan itself will probably not matter, since it neither increases nor decreases their earnings.

I currently cannot assess how crucial this point would be for us regarding the very concrete question of whether we sign or not. Realistically, we do not expect a bankruptcy; otherwise, we would probably back out of a construction project with them. But if one cannot show any flexibility here, that would not be very customer-friendly.
