"Set" and "set" can be used in many places, and there is no difference in meaning. But "order" only means that both parties have an agreement in advance, regardless of whether the agreement can be guaranteed to remain unchanged, emphasizing the process; "Fixed" means that the matter has been settled, and it will not be changed easily, but the result is important.

So you have to customize the tent. Maybe in the early stage of your business, the tent manufacturer will give you drawings, plans, quotations and other preliminary discussions.

If you are satisfied, sign a contract and give a deposit. This is customization. The factory has put your tent into production, and there are changes at this time, which means a lot of economic losses will be involved, so be sure to communicate more in the early stage. It's best not to make too many changes after the decision.
