Hello! First of all I am very grateful to be able to learn from each of you and to Day and the team for hosting this platform. I’m preparing my first WOSB bid for a COTS electrical connector in FSC 5935. It’s above the micro-purchase threshold, the non-manufacturer rule is waived, Buy American/Balance of Payments requirements applies and delivery is 167 days after award. Do I have to obtain country-of-origin documentation from the distributor before bidding, is that correct? Also, how does payment work if supplier requires credit card? Do I pay when items ship and then submit invoice and wait for payment from govt. Thank you!
