Billing & Account
How HarperFlow's Flex plan works, what it costs at each volume, and where Agency and Enterprise fit.
HarperFlow has one plan. You choose how many articles you want published each month, and that choice sets the price. There are no tiers to compare and no features held back behind a higher one.
Pick any volume from 5 to 30 articles a month. The price per article drops as the volume rises — it's $12.90 minus $0.10 for each article in your package:
| Articles / month | Price per article | Monthly price |
|---|---|---|
| 5 | $12.40 | $62 |
| 10 | $11.90 | $119 |
| 20 | $10.90 | $218 |
| 30 | $9.90 | $297 |
Every volume in between is available — 13 articles, 17 articles, whatever matches your cadence. The pricing page shows the full table.
Your subscription renews at the volume you picked until you change it. You can upgrade, downgrade, or cancel at any time, and extra articles are available mid-month at your current per-article rate. See Upgrading and downgrading.
Volume is the only thing that changes. Every subscription — 5 articles or 30 — includes the same premium AI writer, the same brand-voice engine, autopilot, scheduling, the independent quality audit, and the veto window before anything publishes. Buying more articles gets you more articles, not a better writer.
Flex is billed monthly. Annual billing isn't available for Flex yet.
A subscription covers one connected site. Adding a second site creates its own workspace with its own subscription — see Accounts, organizations, and sites for how that separation works, and Managing multiple sites for running several at once.
If you're publishing across several client sites, Agency puts them on one consolidated bill instead of a separate subscription per client. Agency starts at $1,020/month for 120 articles, with per-article rates as low as $6.00 at higher volumes. See Agency billing.
Enterprise is a custom arrangement for larger volume across multiple sites, including your own dedicated pipeline and the option to bring your preferred AI model. It's set up personally with HarperFlow's founder rather than picked off a pricing grid.
Customers who subscribed to Starter, Pro, or Premium before Flex launched keep those plans and prices — nothing changes for you unless you choose to switch. If you'd like to move onto Flex, get in touch and we'll sort it out.
