We keep verifying each system's data, so some cells read "Unconfirmed" or "Not published" until we check them against the vendor's own pages.
Every reservation system here is measured the same way. What a reservation system costs depends on where your guests book: some charge a fee for each guest who finds you through their own diner app, others charge the same monthly fee no matter where the booking came from, and a few also charge for the guests who book on your own website. The table shows that cost for a typical restaurant, whether the plan includes table management and a waitlist, deposits and card guarantees against no-shows, which POS systems it connects to, how long the contract runs and what leaving early costs. If a vendor doesn't publish something, you'll see "Not published" or "Quote only", never a zero.
