> Your base rate includes core features. As your team grows, additional invoices, projects, clients, and tasks are billed based on what you use, so you're never overpaying.
That's a bit bewildering, lol. Especially since they have annual plans.
This clarifies it:
> On Flex billing your first (sign-up) invoice usually covers seats only, because no projects, tasks, clients, or invoices have been tracked yet. Usage-based charges are calculated from the previous billing period, so they first appear at your renewal — not at sign-up. This is why a bill can jump (e.g. from a seats-only $44 to $404 once usage is added).

That's roughly a 10x multiplier, just like aphyr's jump from $13.32 to $133.98!
You're right something doesn't ad up, and seems fishy (to me, bizarre even). But that isn't the author, it's Harvest after the Bending Spoons aquisition.
