BidSync alternative: BidFox vs Periscope S2G

BidFox covers the federal side only: the SAM.gov notices that fit your trade and states, in one ranked email.
On SAM.gov today: 9,032 open federal notices, 2,089 of them set aside for small businesses and 9,032 posted in the last 7 days. BidFox reads all of them every morning.
What BidSync (Periscope S2G) does
Periscope S2G says it notifies suppliers of more than 100,000 government bids a month from state, local, education, port, federal and military agencies, and sends daily bid notification emails.
The free S2G Limited plan lets you view and respond to bids from 1,000+ organizations in the Periscope Agency Network; Periscope notes it represents 2% of the bids available on its Premium plans.
Premium plans are published on its pricing page: State $109 a month (or $779 a year), Regional $131 a month ($911 a year) and National $274 a month ($1,571 a year). Federal, Military and Canada add-ons exist; their prices are not published.
Who BidSync (Periscope S2G) is best for
- Suppliers whose buyers publish on the Periscope agency network.
- Vendors selling to state and local governments, schools and ports in one state, region or nationwide.
- Businesses that want state and local bids first and federal as an add-on.
Where BidFox is different
- BidFox includes every federal notice on SAM.gov in both plans; there is no federal add-on. It does not cover state or local bids.
- Each notice is scored out of 100 for your trade and states, with the reason it fits, and each solicitation is sent only once.
- Starter is $29 a month for one trade in up to 3 states; Pro is $59 a month for all trades and states. Both start with 7 days free.
