Periscope S2G vs RFPFinder, line by line
Where RFPFinder falls short. It is a feed, a scorecard and an alert, not a proposal workspace or a submission portal. State and local coverage is still being built portal by portal. If several people work every bid together, or your agencies require you to submit through Periscope S2G, keep that account.
$29 a month. Locked for life.
Instant alerts, 5 categories × 5 states, set-aside and value filters, scorecards and buyer contacts. $39/mo after the founding seats go.
Our take on Periscope S2G
Periscope S2G is worth keeping on the free Limited tier if you sell to agencies that run Periscope, because that is where you submit. Paying $1,571 a year for National makes sense only if you need their submission workflow across many states; for discovery alone, free feeds cover the same public notices.
Periscope S2G reviews: is it worth it?
- Free tier with real submission to Periscope network agencies
- Monthly billing on every Premium tier
- Large partner agency network
- The free tier is a sliver of the paid volume
- $109 a month for a single state is steep next to flat-rate feeds
- Add-on prices are not published
- Submit bids to agencies that run their procurement on Periscope
- Want a free tier that still lets you respond to network agencies
- Prefer monthly billing on a state or regional plan
- Bid in a few categories or states and want deadline-first lists with a should-bid scorecard
- Want to read full listings, summaries and document links before paying anything
- Need a daily digest or an instant alert more than a bid-management suite
