Billing & Account
Change your monthly volume through the web billing flow or Shopify approval screen.
Open HarperFlow's Plan page and choose the monthly article volume that matches your publishing cadence. The available single-site range is 5–30 articles. The full publishing pipeline is included at every volume.
Use the volume controls for your current web subscription and review the billing confirmation before accepting the change. Web subscriptions use Stripe. Check the amount, any adjustment, and the effective date displayed in the confirmation flow. The payment-method portal and cancellation control are separate actions.
Open HarperFlow from Apps in Shopify admin, then open Plan. Select your new article volume and continue to Shopify's subscription approval screen. Review and approve the replacement recurring charge there; the change is not completed merely by moving the volume control.
Shopify calculates applicable billing adjustments. The confirmation screen is the authority for the charge and effective timing. Your Shopify subscription uses the Shopify price ladder, not the Webflow/WordPress formula.
If you need articles beyond your current monthly volume, use the extra-article control shown for your subscription. Shopify add-ons require their own Shopify charge approval. Check the quantity and total before confirming.
Return to HarperFlow and check the active volume on Plan. If the page shows a pending or declined change, follow its instructions or contact support. Do not start another subscription to work around an unresolved update.
