Billing & Account
HarperFlow's Solo tiers, the annual discount, and where Agency and Enterprise fit.
HarperFlow bills per workspace on a Solo plan, or as one consolidated bill across every client workspace on Agency. Here's what each tier actually gets you.
Every tier includes the same premium AI writer, brand voice, autopilot, and scheduling. The only real difference between them is how many articles you get a month:
Each Solo plan covers one workspace (one connected site). Adding a second site creates its own workspace with its own plan; see Accounts, organizations, and sites for how that separation works.
Every Solo tier can be billed monthly or annually. Annual billing is paid upfront and saves 10% against paying monthly all year:
You choose the interval when you subscribe, and can switch later. See Upgrading and downgrading.
If you already own or admin a workspace with an active paid plan, your next new site automatically gets a standing 20% discount, applied at checkout with no code needed. See Managing multiple sites for details.
If you're managing several client sites, Agency puts them all on one consolidated bill instead of a separate subscription per client. See Agency billing. Enterprise is a custom arrangement for larger volume across multiple sites, set up personally with HarperFlow's founder rather than picked off a pricing grid.
Note: The tiers above differ only in article volume, not quality. A Starter customer's articles use the exact same premium AI writer and brand-voice engine as a Premium customer's. Upgrading gets you more articles, not a "better" writer.
