Your SAM.gov registration is the on/off switch for every federal award and payment you can win. The day it lapses — or silently drops off Active — you're ineligible until it's fixed, and most contractors find out when a payment freezes. Pro guards it every single day so that never blindsides you.
Annual is one payment for the year. We never see or store your card or bank details.
Pro doesn't charge you for anything the government gives away — it just makes sure you never miss a renewal, a status change, or an expiring document across everything you manage.
