What Is GSA eOffer?
eOffer is GSA's online system for submitting an offer for a Schedule contract and, after award, changes to it (eMod).
eOffer in plain English
You prepare your Schedule offer in eOffer: the Special Item Numbers you want, your commercial prices and discounts, past performance and financial documents. You sign in to it with a digital certificate.
After award, you use the same system, called eMod there, to add products, change prices or update your contract.
