Most common complaint

The published prices are promotional and dated; list price is roughly double

A free start exists, but the terms for moving to a paid tier are not on the page

Feature-level add-on pricing makes the final figure hard to anticipate before a quote

Only the floor of the base package is published; everything else is quoted

“Not checked” means exactly that: we have not verified it, not that the platform lacks it. Every other value was read off the vendor’s own pages on the date shown on each platform page.
