Based on the information you've given, Matchpeg Meetings will cover its costs, even
on the
pay-as-you-go rate rather than a subscription, if it saves the following amount of time:
(i.e. if it makes everyone % "more efficient")
For example, if it reduces the length of the meeting by this much, because it takes
less time to run through the action points from previous meetings, or if
it reduces each person's pre- and post-meeting administration by making
it easier to distribute and share information.
This assumes, of course, that Matchpeg Meetings has no
benefits other
than saving time. The truth is rather different: you can't afford
not to use
Matchpeg Meetings.
