Subscription starts, then core use is blocked: Carrier Calculated Shipping is unavailable on Basic and needs a higher Shopify plan.

“To start a subscription but then immediately says no CCS detected which is needed for the actual application and only available on a growth plan, pretty deceptive.”

How to read this

Sources: the product's public listing and reviews, its published price, and public forum threads. Revenue is an estimate unless marked verified by the founder; the formula and its inputs are on the full x-ray. Complaints are grouped by a language model and each quote is a verbatim excerpt, linked to the original review. Build difficulty is a model's reading of the listing and the complaints, not a measurement. Figures are a snapshot of Nov 4, 2026. Corrections: corrections.
