Last verified 2026-09-03. STALE marks a plan we have not re-checked at its source in over 30 days. Every plan above is marked — we flag rather than silently retain. https://goprospero.com/pricing/ (official pricing page, accessed 2026-06-14).

Self-serve price is published and confirmable: $19/user/month month-to-month, $12/user/month billed annually (~37% off per official page). Corroborated via a web search citing goprospero.com and saasworthy.com (goprospero product). Unlimited proposals, 14-day free trial. Cross-checked against saasworthy.com.

A new dated entry is stamped here each time the price moves — the record builds itself.
From 2026-10-16 our record reflects a correction we published, not a vendor price move, so earlier figures are not compared with it.
Tracked since June 2026. No change record has cleared two sources yet, so nothing is published on the wire.
Corrections to this record
Changes we made to our own record of Prospero, newest first: a figure read again on the vendor's page, a plan it no longer lists, a note. None of them is a price change by Prospero. Every correction on the site is in the corrections log.

Premium. Basis corrected, no new figure. The recorded monthly price was the annual-billed rate while the plan's own note named the month-to-month one; the schema reserves this field for the month-to-month price and carries the saving in the annual discount, so the two recorded figures swapped places. Both were already in the record and neither was re-read.

This standing as a plaque
Prospero currently holds a gold deskmark here — Rank 2 of 7 · Proposal Software. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Prospero moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
