Pain points solved

Built for sellers who cannot afford silent profit leaks.

  • Fees are hard to see: estimate Etsy fees, payment fees, listing fees, shipping, packaging, COGS, discounts, and Offsite Ads before publishing.
  • Sales can erase margin: test discount and free-shipping scenarios before launching a promotion.
  • Listings need fast QA: flag missing details, thin descriptions, risky wording, and weak buyer keywords while editing.
  • Orders need profit review: estimate visible order margin and export local summaries without auto-shipping or hidden automation.
  • Replies need care: use seller-reviewed templates and optional AI drafts without automatically sending buyer messages.

Refund structure by plan type

Subscriptions: cancel anytime to stop future billing. If a non-waivable law requires a refund, credit, or pro rata adjustment for unused service time, we apply the legally required formula for the customer’s jurisdiction.

Lifetime licenses: one-time perpetual licenses are generally final after activation or use. We keep a narrow voluntary pre-activation review window and any required legal exceptions for duplicate charges, payment errors, non-delivery, or unresolved core defects.
