In July of 2018 we signed a purchase order agreeing to supply materials in accordance with our terms. Terms are 50% deposit before we place the order. We did not receive the deposit and we did not place the order. In September of 2018 we received a stop work letter for all subcontractors and suppliers on the project. Now it is January 2020 and the company is requesting we fulfill our PO obligation. Are we legally obligated to perform this after such a long stop work order? We told them the only way we would be able to do it is with an increased price due to recent tariffs and AD and they are saying that is not acceptable or that the new price we quoted is too high. The stop work order was due to owners failure to pay the GC. If we go through with this project along with the higher price we would prefer our payment terms change to 75% up front or 100% upfront.
