Maximum Order Limit. Basically it is interchangeable with MOT or Maximum Order Thereshold.

It is the price at which you gsa ser successful lists schedule pricing no longer applies and becomes a negotiated price. Example, if I sell chairs that list for gsa ser verified lists $200 on my gsa ser site lists contract for 50% off and my MOT is $100,000, if I get an opportunity to sell more than 1000 chairs I can negotiate a different price.

With that said, you can ALWAYS sell to the government for less, just not more unless you’ve exceeded MOT.
