Get in touch

Email hello@resellfees.com. We read everything and reply to fee reports first.

Reporting a fee change

Include the platform, what changed, the effective date, and a link to the platform's own announcement or updated fee page. Changes are verified against the source before the calculators are updated and the change log gets a row.

Reporting a calculation error

Send the calculator URL (it includes your inputs after the # sign), the result you expected, and ideally a screenshot of the real fee statement from the platform. Most reports turn out to be a category or option difference, but genuine bugs are fixed within a few days.

Requesting a platform

Tell us which marketplace and roughly how many sellers you think would use it. Platforms with published, stable fee schedules are the easiest to add.
