What’s included in this release
eBay
Verified standard non-Store schedule. Single-item order estimate. Use your own rates for category and Store exceptions.
Etsy
US bank accounts only. Processing rates are editable. Regulatory and seller-specific taxes must be entered as other costs.
Amazon
Fulfillment, storage and inbound fees must be entered from your product-specific Amazon fee estimate.
Shopify
US standard online card starting rates. Premium, international and alternative payments can differ. Override with your actual rate.
Update log
September 18, 2026 — Initial configuration. Added US marketplace estimates. eBay, Etsy, Amazon and Shopify official reference pages checked. US standard schedules are the starting assumptions; category and account-specific exceptions still require the seller’s current terms. Publication dates are not fee effective dates; the sources do not establish a single effective date for every rule.
Our update process
Review official sources before deployment, then monthly and whenever a platform announces a change. Update the versioned fee configuration, formula tests and this log together. The current app does not automatically retrieve live fees.
