I’ve had billion dollar companies screw me out of 300$ (a lot of money for me at the time, haha) for no reason except that they could.
I can confirm, I used to work for one. When the budget got tight, all contracts would be paid on the due date and never before (net90 will get paid on the 90 day.) Orders that arrived on the dock would be sent back. And it was too everyone, not a judgement of who could sue or who was also a customer.
I fully encourage large deposits and payment terms that you want.
