I'd assume monthly but I'd rather not have to assume.

And I'd've assumed $/yr. Otherwise … $1M/y for Slack? I figure that's probably too high … or someone is getting fleeced.

But yeah, the number of times I've seen management spreadsheets doing math on "$" where "$" is a weakly-typed mix of $/mo & $/yr, and then the "result" used to "justify" decisions…

We've normalized the prices to per year based on the feedback - thanks everybody
