Review management software cost: Review Software Price Index

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

11 of the 28 named sources that could be read published a usable figure; 17 published none and are recorded as not published, never filled in; 2 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in USD (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 12 figures, never sentences; 376 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the median and range of PUBLISHED monthly prices across review-management vendors, split by unit (per location, per domain, per seat) and by tier, with the share of vendors that are quote-only recorded as its own figure - which on this read is most of the enterprise end; plus, for each quote-only vendor, the prices that third-party readers have published for it, carried as an observation of the reader and never as the vendor's own rate.

376 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
