How to check a result
Compare a single order with your actual marketplace statement. Processing, tax treatment and rounding can differ by account. Use actual fee amounts for unsupported tiers or caps. A zero fee is an assumption that no charge applies.
Sign-in and saved data
Free calculators work without an account and do not save your figures automatically. Existing accounts can sign in to manage their settings. New accounts and Pro subscriptions are not open yet. Saved records remain protected by account ownership checks.
Billing and cancellation
The website is not collecting subscription payments. Monthly and annual checkout, cancellation and payment recovery have been tested in Stripe's sandbox. Live billing still needs its final business and tax settings. Subscribers will be able to manage cancellation through the billing portal.
Exports
Use PDF for individual calculations and documents. Use CSV for complete product and expense data. Reports preserve their original assumptions rather than silently adopting new fees.
